Hi,

TL;DR : I face a syntax error when building flext under windows, although I successfuly built it under OSX.

I am trying to build flext for Max 7 with msvc.
After configuring config-win-max-msvc.txt, the second run of build max msvc build fails as follows :

------------------------------------------------

Sorry for that French command line tool (still cannot figure how to change its language).

So the error here is :

d:\downloads\flext-master\source\flclass.h(1119): error C2061: erreur de syntaxe : identificateur 'Point'
NMAKE : fatal error U1077:

Which translates as syntax error : indentifier 'Point'.
Identifier 'Point is only found in flclass.h in this bloc (ll.1115-1119) :

1115 #if FLEXT_SYS == FLEXT_SYS_MAX
1116    char **indesc,**outdesc;
1117
1118    static void cb_assist(flext_hdr *c,void *b,long msg,long arg,char *s);
1119        static void cb_click (flext_hdr *c, Point pt, short mods);

I can't find how to work around this error, since it lays in fext's source's headers...
PLUS I successfuly built flext and flext-based externals under OSX (using GCC) this week.
How can a syntax error be plateform-dependent ?

I also note the warning D9002 : unknown '/YXflext.h' option ignored...

If anyone has any insight on this...

TS

this is more of a question than an issue:

when building flext as a dynamic library, you get something like libflext-pd.so against which flext-externals link.

however, afaiu libflext-pd.so will not be able to deal with multiple floatsizes (either it can handle Pd32 (single precision) or Pd64 (double precision); but not both).

so how should this be handled?

my naive suggestion would be:

but maybe you have better ideas...

I'm encountering a problem with the pointers to the inputs/outputs.
For some reason, when I create a 2-in-2-out object, the first input and the second output point to the same buffer/address.

Is this a bug? Or is my assumption flawed? Or did I do something strange in the instantiation?

My system: Puredata vanilla 0.49-1, OS X 10.14.1, Apple LLVM version 10.0.0 (clang-1000.11.45.5)

This simple external should enable you to reproduce the issue:

#include "flext.h"
#include <cassert>

#if !defined(FLEXT_VERSION) || (FLEXT_VERSION < 401)
#error You need at least flext version 0.4.1
#endif

class TestObject : public flext_dsp
{
  FLEXT_HEADER(TestObject, flext_dsp)
  
public:
  TestObject()
  {
    AddInSignal("audio in 1");
    AddInSignal("audio in 2");
    AddOutSignal("audio out 1");
    AddOutSignal("audio out 2");
  }
  
protected:
  virtual void m_signal(int n, float *const *in, float *const *out) override;
};


FLEXT_NEW_DSP("TestObject~", TestObject)

void TestObject::m_signal(int n, float *const *in, float *const *out)
{
  // Inputs and outputs should not point to the same memory!
  assert(in[0] != out[0]);
  assert(in[0] != out[0]);
  assert(in[0] != out[1]);  // assertion triggers here!
  assert(in[0] != out[1]);
  assert(in[1] != out[0]);
  assert(in[1] != out[0]);
  assert(in[1] != out[1]);
  assert(in[1] != out[1]);

  // talk-through
  while (n--)
  {
    out[0][n] = in[0][n];
    out[1][n] = in[1][n];
  }
}

I'm in the process of packaging flext for Debian (and derivatives).
However, for this to work I would need a "proper" release of flext (for me it's enough if you create a new tag)

So: is there an estimated timeline for the next flext (v0.5.1 iirc) release?

Hello.

I ran into problems using FLEXT_USE_CMEM, it result in a call-loop:

void *operator new(size_t bytes) in flsupport.cpp calls flext_root::operator new(bytes);
which is inlined with: ::operator new(bytes); defined in flsupport.h
which calls the global new operator again.

Not sure what the idea was about FLEXT_USE_CMEM, but this seems wrong.
It looks like neither the global new operator nor the inline new-operator is necessary?

Version 6 and 7 of the Max-SDK contain elements (e.g. t_buffer) which are marked as C74_DEPRECATED.

Is this an issue that comes from flext? chikashimiyama/Pd_leapmotion#3

Trying to build flext in order that I can get the py externals working on my system.

After adjusting all the file locations in config-win-max-mingw.txt I get the following:

mingw32-make -f C:/flext-master/buildsys/gnumake-sub.mak  PLATFORM=win RTSYS=max COMPILER=mingw BUILDPATH=C:/flext-master/buildsys/ PKGINFO=package.txt BUILDCLASS=flext USRCONFIG=config.txt USRMAKE=build/gnumake-win-mingw.inc TARGETMODE=release TARGETTYPE=single _build_

Here's the first part of my config file:

flext should use pthreads for Pure Data and the Max threading API, nothing else.

it would be great to have a @[email protected] file (or similar), that outputs the proper CFLAGS and LIBS for dynamically linking with flext on @System@.

e.g.

 $ pkg-config --cflags pd-flext
 -I/usr/local/include/flext -DPD -DFLEXT_SHARED
 $ pkg-config --libs pd-flext
 -lflext-pd

lower priority: pkg-config also has a --static flags that outputs flags for static linking:

 $ pkg-config --static --cflags pd-flext
 -I/usr/local/include/flext -DPD
 $ pkg-config --static --libs pd-flext
 -lflext-pd_s

Hi, so I'm trying to build and install flext.

at step 1.2 "Building and installing flext" I entered "bash build.sh pd gcc" into the terminal, then "buildsys/config-mac-max-gcc.txt" was created and I edited it to refer to the new Pd Vanilla's path, so all I did was, instead of Pd-042-5 including "PDPATH=/Applications/Pd-0.47-1-64bit.app/Contents/Resources"

then I tried building it again and got three errors, here's everything...

A default package configuration file has been created.

Hi...

Since pulling the latest version of Flext master into my project, I am getting link errors:

duplicate symbol 'operator delete[](void*)' in:

etc

I am defining FLEXT_USE_CMEM which used to fix this (I think).
I am also using FLEXT_INLINE and FLEXT_USESIMD

Any ideas?

Startup of secondary threads in flext::StartHelper (flthr.cpp) and flext_base::StartQueue (flqueue.cpp) use (non-thread-safe) static variables as flags and Sleep() calls to wait for startup. This is very unelegant and error-prone.

On Yosemite, both for PD and Max builds I was getting the error:

ld: framework not found vecLib

It looks like that name has been deprecated for some time and now doesn't work any more. Just changing vecLib to Accelerate in buildsys/mac/gnumake-gcc.inc got me building again.

Hi,

what's this error? how to fix it? it was ok with pd 0.45 but error with 0.47

ubuntu 14.04 64bit
pd 0.47

thanks,
akntk

Currently, there are still a few per-instance definitions in the tutorial examples.

followed the instructions but I'm stuck at this point:

When trying to compile flext-based externals on Github Actions/macOS, I'm getting errors like these:

When I comment a few things out in source/flsupport.h (lines 126 and 127):

... those errors are gone, but instead of them there are some warnings:

Despite those warnings, the externals are successfully created: https://github.com/mgeier/ssr/actions/runs/136504305

I don't know whether they actually work as expected, though, because I don't have a Mac to test them.

I have no idea what's the right course of action is here, I just wanted to report my experiences ...

On Linux (GCC) everything works fine, BTW.

why is v0.5.1 a direct successor of v0.6.0?
should the tag read v0-6-1 instead?

Hello.

I ran into problems using flext when compiling externals (into a library) without using FLEXT_USE_CMEM on a bela (using a xenomai linux).
I did not dig deep - but it results in a Bus Error

On a desktop linux (archlinux) it does not show this behaviour - the externals load and work fine.

Any ideas where this may come from?

Is dyn~ / dynext dead?

Hello,

We are looking to writing externals for Jitter (in Max) and GEM (in Pd).
Our library is in C++, so I thought flext would be a good fit.

Questions are:

• is this project still maintained and still can work agains the most recent Max and Pd versions?
• I am also looking for Jitter and GEM examples of externals that compile with this

I saw some forks of this have newer material that is not in this repo so I guess there is still interest in this.

it seems that i cannot properly link against the dynamic library of flext.

My rough Makefile (i've used make install DESTDIR=/tmp/flex for pseudo-installing flext):

FLEXTDIR=/tmp/flex/usr/local/
CXXFLAGS=-DPD -I$(FLEXTDIR)/include/flext -I/usr/include/pd -fPIC -DPIC
LDFLAGS=-rdynamic -shared -Wl,-rpath,"\$ORIGIN",--enable-new-dtags -fPIC
LIBS=$(LDFLAGS) -L$(FLEXTDIR)/lib -lflext-pd_d

henon.pd_linux: henon.o
    g++ -o $@ $< $(CXXFLAGS) $(LIBS)

henon.o: henon.cpp
    g++ -o $@ -c $< $(CXXFLAGS)

this gives me a nice henon.pd_linux.
But when I run it, it cannot be loaded with the error

./henon.pd_linux: ./henon.pd_linux: undefined symbol: _ZN17flext_base_single4InitEv

which translates to flext_base_single::Init() not being found.

everything works fine when i link against the static version of flext -lflext-pd_s

Hi
Been experimenting with Pd_leapmotion (based on flext) for some time and recent Mac OS updates seem to crash with this. Thought I'd build the flext code and investigate. simple1 example crashes in exactly the same way - huge stream of warnings from mach_o_image_reader.cc (see attached text) when creating the simple1 object.

Using Pd-l2ork.

Any help appreciated.
David

pd-l2ork.crash.txt

A strange error message happens with newer versions of Pd, but not with Pd 0.43.
See also http://grrrr.org/pipermail/flext/2015-January/000505.html

I would need some input concerning the situations the bug happens, and when it does not.

The should not be supported, due to the lack of maintenance possibilities.

I'm experiencing a weird crash on OS X 10.14.1 (Mojave) with any externals built with flext.

When I try to load a (flext-based) external, the app just closes / crashes.
I don't see any log entry in the system log nor the pd console (after I restart it).

What I did:

1. built and installed flex with build.sh (edited config file to match my installation, then build and install)
2. I build one of the tutorial externals (e.g. simple1 or signal1~) - by going into the tutorial/simple1 directory and then doing a ../../build.sh pd gcc
3. Install the built external
4. start puredata
5. create a new patch and (try to) add a new object

Is there another place where I could look for hints on why it crashes?

I'm using pd-0.49-1 and gcc -v yields:

Apple LLVM version 10.0.0 (clang-1000.11.45.5)
Target: x86_64-apple-darwin18.2.0

hi,

i'm trying to build flext for 64-bit Pd (amd64, not double precision) on Windows 10 using MSVC. since MSVC doesn't allow inline assembly on 64-bit, this fails on flsimd.cpp and (with SIMD disabled) lockfree/cas.hpp.

is it possible to do a 64-bit build? should i be using MinGW or Cygwin instead of MSVC?

these links are broken

for Windows (http://synthesisters.com/pluggo3/downloadMaxWinSDK.php)
for OSX (http://www.synthesisters.com/sdk/max.php)

here's where it seems to live now https://cycling74.com/downloads/sdk

trying to install Flext in Mac OS Mojave I have having this error:

I have tried to put the flag in buildsys/mac/gnumake-gcc.in but it is not changing nothing....

My compiler version is:

Apple LLVM version 10.0.0 (clang-1000.10.44.4)
Target: x86_64-apple-darwin18.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Thank you so much.

when initializing automake, the foreign option should be passed (since a number of files (e.g. README) required to be strictly GNU autotools conformant) are missing.

e.g. configure.ac:10

 AM_INIT_AUTOMAKE([foreign])

this is needed to bootstrap the project with the standard autoreconf -fiv (instead of ./bootstrap.h which adds the --foreign manually)

Misleading output of --help regarding --with options
When .configure the package, in the help it is written that options to provide STK and SndObj headers are --with-stk and --witch-sndobj, however configure script doesn't recognize them.
I figured out that correct options are similar to --with-sdkdir and need to include dir in the end: --with-stkdir and --with-sndobjdir
Final command that worked for me:

./configure --with-stkdir=/usr/include/stk --with-sndobjdir=/usr/include/SndObj --with-sdkdir=/usr/include/pd

Include dirs messed up
After ./configure script succeeded and both SndObj and STK were enabled (I inspected configure.status and Makefile) actual compilation fails with error

flbase.cpp:31:22: fatal error: g_canvas.h: No such file or directory

that apparently means that somehow even if configure script confirmed the file exists (it actually exists, I checked), include dirs are not properly passed to the compiler.

Further investigation confirms that SndObj and STK include paths somehow overwrite instead of appending to include path given to compiler, because building flext without them succeeds.

Building via build.sh works without problem
