ultimaker / libarcus

Communication library between internal components for Ultimaker software

Arcus

This library contains C++ code for creating a socket in a thread and using this socket to send and receive messages based on the Protocol Buffers library. It is designed to facilitate the communication between Cura and its backend and similar code.

License

Arcus is released under terms of the AGPLv3 License. Terms of the license can be found in the LICENSE file. Or at http://www.gnu.org/licenses/agpl.html

But in general it boils down to:
You need to share the source of any Arcus modifications if you make an application with Arcus.

How To Build

Note:
We are currently in the process of switch our builds and pipelines to an approach which uses Conan and pip to manage our dependencies, which are stored on our JFrog Artifactory server and in the pypi.org. At the moment not everything is fully ported yet, so bare with us.

If you want to develop Cura with libArcus see the Cura Wiki: Running Cura from source

If you have never used Conan read their documentation which is quite extensive and well maintained. Conan is a Python program and can be installed using pip

1. Configure Conan

pip install conan==1.56
conan config install https://github.com/ultimaker/conan-config.git
conan profile new default --detect --force

Community developers would have to remove the Conan cura repository because it requires credentials.

Ultimaker developers need to request an account for our JFrog Artifactory server at IT

conan remote remove cura

2. Clone libArcus

git clone https://github.com/Ultimaker/libArcus.git
cd libArcus

3. Install & Build libArcus (Release OR Debug)

Release

conan install . --build=missing --update
# optional for a specific version: conan install . arcus/<version>@<user>/<channel> --build=missing --update
cmake --preset release
cmake --build --preset release

Debug

conan install . --build=missing --update build_type=Debug
cmake --preset debug
cmake --build --preset debug

Creating a new Arcus Conan package

To create a new Arcus Conan package such that it can be used in Cura and Uranium, run the following command:

conan create . arcus/<version>@<username>/<channel> --build=missing --update

This package will be stored in the local Conan cache (~/.conan/data or C:\Users\username\.conan\data ) and can be used in downstream projects, such as Cura and Uranium by adding it as a requirement in the conanfile.py or in conandata.yml.

Note: Make sure that the used <version> is present in the conandata.yml in the libArcus root

You can also specify the override at the commandline, to use the newly created package, when you execute the conan install command in the root of the consuming project, with:

conan install . -build=missing --update --require-override=arcus/<version>@<username>/<channel>

Developing libArcus In Editable Mode

You can use your local development repository downsteam by adding it as an editable mode package. This means you can test this in a consuming project without creating a new package for this project every time.

    conan editable add . arcus/<version>@<username>/<channel>

Then in your downsteam projects (Cura) root directory override the package with your editable mode package.

conan install . -build=missing --update --require-override=arcus/<version>@<username>/<channel>

Using the Socket

The socket assumes a very simple and strict wire protocol: one 32-bit integer with a header, one 32-bit integer with the message size, one 32-bit integer with a type id then a byte array containing the message as serialized by Protobuf. The receiving side checks for these fields and will deserialize the message, after which it can be processed by the application.

To send or receive messages, the message first needs to be registered on both sides with a call to registerMessageType(). You can also register all messages from a Protobuf .proto file with a call to registerAllMessageTypes(). For the Python bindings, this is the only supported way of registering since there are no Python classses for individual message types.

The Python bindings expose the same API as the Public C++ API, except for the missing registerMessageType() and the individual messages. The Python bindings wrap the messages in a class that exposes the message's properties as Python properties, and can thus be set the same way you would set any other Python property.

The exception is repeated fields. Currently, only repeated messages are supported, which can be created through the addRepeatedMessage() method. repeatedMessageCount() will return the number of repeated messages on an object and getRepeatedMessage() will get a certain instance of a repeated message. See python/PythonMessage.h for more details.

Origin of the Name

The name Arcus is from the Roman god Arcus. This god is the roman equivalent of the goddess Iris, who is the personification of the rainbow and the messenger of the gods.

Java

There is a Java port of libArcus, which can be found here.

libarcus's Issues

cmake cannot find PROTOBUF

I test %PROTOBUF_LIBRARY%, % PROTOBUF_INCLUDE_DIR%, shows my path.

`CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):

build in windows erro

how can i solve it...

FindSIP.py is run with Python 2 instead of 3

While FindSIP.cmake requires Python 3.4.0, FindSIP.py is apparently run with the Python 2 interpreter on Debian.

Since my system only has python3-sip installed, this results in the following error:

Traceback (most recent call last):
  File "~/cura/libArcus/cmake/FindSIP.py", line 10, in <module>
    sipcfg = sipconfig.Configuration()
AttributeError: 'module' object has no attribute 'Configuration'
CMake Error at cmake/FindSIP.cmake:58 (MESSAGE):
  Could not find SIP
Call Stack (most recent call first):
  CMakeLists.txt:22 (find_package)

Running FindSIP.py with python3 works and produces the expected output.

Hi, is there anyone knows this issue,

when I make the libarcus on cygwin, it display below:

version of protobuf

Is it suppossed to be currently unreleased version 3 of protobuf? Or v2 still can be used?

AttributeError: module 'Arcus' has no attribute 'SocketListener'

Hi, people. I'm new with Cura. I'm trying to install it. I have installed Protobuf, libArcus and Uranium in my MacBookPro with OSX Yosemite.

One of the cura plugins named CuraEngineBackend is failing. I isolate the issue executing this python call in bash:

python3.5 -c "import plugins.CuraEngineBackend"

And this is the exception:

But the SocketListener class is not included on Arcus/init.py.

Can you tell me if it is a bug? Or I make a mistake on the install process.

Thanks a lot for your time

Was hoping someone could tell me why this was happening. Thanks!

EDIT: IT may have some thing to do with this, when building cmake:

WARNING: Target "python_module_Arcus" requests linking to directory "C:\msys64\mingw64\lib\python3.5". Targets may link only to libraries. CMake is dropping the item.

Problem is mingw32-w64 doesn't give you a .lib file, just a directory

SOVERSION / VERSION / Cura version mismatch

I ran into this problem while attempting to package Cura up for Debian:
There seems to be a general disagreement over which versioning scheme to use for libArcus.

• The "release" uses the same scheme as Cura (ex. 2.3.0)
• The library version is currently 1.1.0
• The SOVERSION (i.e. API level) is 3

While technically not an issue, it is highly confusing and causes lintian to throw a tantrum. Silencing it is an option, but I'd rather have an official opinion why Arcus doesn't use a more consistent versioning scheme.

Even better, it would be nice if the three versions would match up.
I understand that this will most likely introduce a discrepancy between Cura and libArcus, but I don't think it will be a major problem. One can always require a specific library version, if necessary.

Hi, I managed to solve the FindSIP issue by installing python3-sip-dev, so now it shows Found SIP version: 4.18.1 even though running sip -Vstill shows 4.19.3. Shrug. But now I get this error when attempting to sudo make

[2.1] - Multi-architecture installation not possible anymore

Because debian allows multiarch installation of libraries, it is needed to install to a specific path.
CMAKE_LIBRARY_PATH usually sets this path, but it doesn't work anymore on 15.10 branch.
The reason could be commit 6eeb674 here the */lib path has been hardcoded.

give me instrution,thankyou...

AttributeError: module 'Arcus' has no attribute 'SocketListener' on windows

@Ghostkeeper @daid @fabianrodrigo

i'am also encountering the issue "No attribute SocketListener".
and
commands:

python3.5
import Arcus
print(Arcus.__file__)

get:
somethingsomething/python3.5/lib/site-packages/Arcus/init.py

the big trouble for me is: i don't know how to build the libArcus on the windows, so the file Arcus.pyd can't be generated out. when i follows the build guidelines about Arcus on the webpage, also guideline about protobuf, they are no effective when i try to compile or install, every compile path is full of errors.

Could you point me out more detailed compile or install procedures? many thanks!

I have a check the inst folder, and found there's file inst\lib\libArcus.a, it seems the libArcus should has built, and I think the above problem is just a linking problem, but I don't know how to handle it.

will anybody instruct me how to handle the problem?

Also as a note, instructions for building should tell a person how to tell CMAKE to find python and SIP.

So what's this directory: "google" ? It doesn't appear in the library's project.

release snapshots please

Please give us release snapshots for this project that correlate to releases for uranium and cura.

Error 1 and 2 on make and/or minGW-make

Dear,

this is how far I got. tried both "make" in MSYS environment and "minGW32-make" in normal terminal enivronment (both built by cmake in the corresponding flavour).

one thing to add, I did build protobuffer 3.0.0 beta 2, with cmake instead of using minGW.
this because of the handguide provided by protobuffer.

for the rest: I'm lost

Linux 64 bits issue

Hi, in order to compile Cura (and all the libs) I had to patch up the CMakeLists.txt to correctly use Lib_Suffix.
I share my lib64.patch, if you found it acceptable can you add it to the code?
lib64.txt

libArcus.so SONAME and .so.VERSION don't match

When building libArcus 2.1.3, the SONAME gets (correctly) set to libArcus.so.2, but the library itself is named libArcus.so.1.0.0.
While this inconsistency does not cause any immediate problems, it's a bad idea and should be fixed.

This line:
set(ARCUS_VERSION 1.0.0)
should read:
set(ARCUS_VERSION 2.1.3)

installation issue

Hello,

protobuf is already installed in ubuntu system from repository. Then while compiling this library from source, the system gives the following error:

///////////////////////////////////////////////////////////////

Any hint to get around this issue ?

Thanks

Use "stable" protobuf.

The library can't be built using protobuf version that is present in repositories:
example.protoexample.proto::1:101: :Unrecognized syntax identifier "proto3". This parser only recognizes "proto2".10: Unrecognized syntax identifier "proto3". This parser only recognizes "proto2".
Use of proto3 requires manual build of protobuf beta version that is veeeery unconvinient.

Building in Windows

When I try to configure in cmake, I got this error:

When I tried setting PROTOBUF_INCLUDE_DIR to its location
set(PROTOBUF_INCLUDE_DIR "C:/MinGW/msys/1.0/local/protobuf-master")
the error still exists.

I am using "MSYS Makefiles" for generating the files.

Issues with installing- could not find SIP despite being installed

When attempting to run cmake on libArcus, cmake exits with the error "Could not find SIP". However, SIP is on my system and I have tried several methods of installing and checking. Here's what I've done so far (for reference, I'm running Debian Stretch):

• Install sip using pip3 install sip as mentioned in the SIP documentation
• Downloading sip-4.19-cp35-cp35m-manylinux1_x86_64.whl from the link in Running Cura from Source, then running pip install on that file. It exited with error, saying it wasn't a supported wheel on my platform, so I tried sip-4.19-cp36-cp36m-manylinux1_x86_64.whl (the other possibility from that link), and had the same issue.
• The same as above but with pip3, which successfully installed but was not found by libarcus
• Installing the sip-dev package from the Debian repositories through my package manager, which also succeeded but was not found by libarcus
• Extracting the .whl's mentioned above using unzip, but the contents only contained a few text files (METADATA which recommended I use pip3 to install, and RECORD and WHEEL which had some record and configuration stuff) and an executable called sip.so. I tried running it and got a segmentation fault, and neither python nor python3 could run it. This was true in both the .whl's.

I know sip is installed because I can run an import sip from the python3 console, so I'm not sure why libarcus still won't find and use it. Any help here would be much appreciated!

make problem

In the process of compiling libArcus, the implementation of cmake is successful, but the implementation of the make command, the compiler error. The following is the exception information:
/usr/bin/ld: /usr/local/lib/libpython3.6m.a(abstract.o): relocation R_X86_64_32S against _Py_NotImplementedStruct' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libpython3.6m.a: error adding symbols: Bad value
collect2: Error：ld return 1
make[2]: *** [Arcus.so] error 1
make[1]: *** [CMakeFiles/python_module_Arcus.dir/all] Error 2
make: *** [all] Error 2
`
I have read some information that 64-bit system will compile Python when the problem occurs, but I re-compiled Python. Again make make libArcus when the implementation of this error message.
My environment is centos 7 python3.6 sip4.19.2
Will the following give some good advice? Thank you

Could not find SIP

Platform: Ubuntu 17.04
libtool: (GNU libtool) 2.4.6
SIP: 4.19.3

Steps to Reproduce:
Follow CuraEngine installation instructions from https://github.com/Ultimaker/CuraEngine
Get down to the install libArcus step
When executing cmake .. I get the following error:
-- Found Protobuf: /usr/local/lib/libprotobuf.so;-lpthread (found suitable version "3.3.2", minimum required is "3.0.0") -- Found PythonInterp: /usr/local/bin/python3.4 (found suitable version "3.4.6", minimum required is "3.4.0") -- Found PythonLibs: /usr/local/lib/libpython3.4m.a (found suitable version "3.4.6", minimum required is "3.4.0") CMake Error at cmake/FindSIP.cmake:64 (MESSAGE): Could not find SIP
Yet I do have SIP installed. Any hints on what I should do?

LibArcus build is broken on Linux with Python 3.x

08a7108 introduced a change in FindSIP.py that doesn't allow to "import sip" when sys.platform isn't "win32".

arcus in 64bit windows

I am trying to set up arcus with Python bonding in 64-bit windows. I successfully installed protobuf. Any detail suggestion on how to use Microsoft Visual C++ to build Arcus in 64-bit windows?

Missing check for Initial state

In Socket::connect there is a check if the socket is in the initial state. But in Socket::listen that check is missing. Shouldn't that there be in place too?

Make Error of Libarcus while building CXX Object

I'm trying to build curaengine on a shared web hosting server where I DO NOT have root access and cannot use the package manager. I currently cannot get my Libarcus make to work. Any help or tips would be greatly appreciated.

Notes: I have been able to get cmake working with SIP by installing in a customized directory path; I've tried disabling python bindings by passing -DBUILD_PYTHON=OFF to CMakes.

Try and use libprotobuf-lite

For embedded systems, the use of libprotobuf-lite could safe precious resources. Unless we have a hard dependancy on the full libprotobuf, we could suffice with libprotobuf-lite.

Could not find SIP

Platform: win10
version: sip 4.19.8 for python 3.6.5
I have already installed sip via "python -m pip install sip". And I can find sip.pyd at "C:\Users\CZB\AppData\Local\Programs\Python\Python36\Lib\site-packages" and a folder "C:\Users\CZB\AppData\Local\Programs\Python\Python36\Lib\site-packages\sip-4.19.8.dist-info".
Whether I add these to PATH or not, I get the same error:

SIGPIPE crashes program

In a program of which the details I can't disclose, I am having trouble with the following error. This is the output of GDB:

Program received signal SIGPIPE, Broken pipe.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

Is there a way to catch this, or prevent this SIGPIPE from interrupting the program? It seems to check in a UNIX system directory that normally contains the connection to the other side, but if that connection is gone, the file won't exist which causes it to crash.
It's worth noting that unlike Cura, this application is not working with local ports but actually connects to a remote device.

The stack trace doesn't indicate it, but at position #1 the error seems to occur at line 509 in Socket_p.h.

Windows install: no make file

When attempting to install libArcus on Windows 8.1 (using MinGW / MSys) after running CMAKE, there are no make files generated so the MAKE command fails (Step 3 in the the BUILDING section of the readme). It looks like Visual Studio solutions and projects are created.

When attempting to build the Arcus.sln file via Visual Studio, it keeps throwing Unresolved Externals errors in relation to protobuf even though I followed the Protobuf install directions with no errors.

Building Protobuf on Windows

Hi Guys,

I am using the tutorial "Installing Protobuf on Windows C++" to build Protobuf using MinGW. But in Step "$ ./configure", I find "stdint.h" and "inttypes.h" are not found. At the next step "$ mingw32-make", it reports error: "./google/protobuf/stubs/port.h:44:20: stdint.h: No such file or directory."
Does anybody have the similar problem? (I am new to MinGW, should I copy and cover C:\MinGW\include to C:\MinGW\C:\MinGW\msys\1.0\include ?)
My protobuf locates at C:\MinGW\msys\1.0\local\protobuf-master.
Thanks in advance.

issues when developing protobuf on win10

hi, I am very new to this.
when I am trying to install protobuf, I run autogen.sh, and I got this

$ ./autogen.sh
++ autoreconf -f -i -Wall,no-obsolete
Can't locate Autom4te/ChannelDefs.pm in @inc (you may need to install the Autom4 te::ChannelDefs module) (@inc contains: /mingw/share/autoconf /usr/lib/perl5/sit e_perl /usr/share/perl5/site_perl /usr/lib/perl5/vendor_perl /usr/share/perl5/ve ndor_perl /usr/lib/perl5/core_perl /usr/share/perl5/core_perl .) at /c/MinGW/bin /autoreconf-2.68 line 40.

can anyone help me with that? thanks in advance

tag a 1.1.0 release please

Please tag a 2.1.0 release to go along with all the other 2.1.0 releases for the other bits of the software stack: uranium, cura etc.

libArcus can't find python3 in /usr/local/bin for mac

I have installed python3 in /usr/local/bin on mac and libArcus comaplains of not having correct version of python.
Could NOT find PythonInterp: Found unsuitable version "2.7.10", but required is at least "3.4.0" (found /usr/bin/python)

I am not able to create symlink as well ... because of El Capitan. Is there a way to tell libArcus to find python3 in a particular dir/path?

Hi Guys,

I want to build the library. I installed libtool (sudo apt-get install libtool) and I followed the steps to install protobuf.
But when I try to build the library i have this problem.

However, I already did these steps:
Navigate to protobuf-master/python
sudo apt-get install python3-setuptools
sudo python3 setup.py build
sudo python3 setup.py install

Can anybody help me, please?

Thanks in advance
