ODE 0.13 Ubuntu 16.04 about grsim

It seems that the problem is like this:
https://stackoverflow.com/questions/13489940/stupid-bug-with-fscanf-comma-instead-of-point
I solved the problem setting the following environment variables before executing grsim:
$ export LANG=en_US.UTF-8
$ export LC_CTYPE=en_US.UTF-8
$ export LC_ALL=en_US.UTF-8

Many of our team had this problem. Eventually it turned out to be because their Ubuntu was configured for the dutch format, where the comma is used as a decimal. The grsim xml uses dots as decimal, so there it probably goes wrong when ODE reads these. So make sure your system uses dots as decimal.

Yes, the first time grSim was working, but later emerge this problem, and I thought that problem was GCC or Operative system (Ubuntu 16.04), then I tested with Ubuntu 14.04 but was same.

@mahi97 Hello,
Possibly I have a solution. I think there are issues with this vartypes file, because:
I deleted vartypes and I have reinstalled it and I had this error:
[ 41%] Building CXX object CMakeFiles/vartypes.dir/vartypes/gui/moc_VarItem.o In file included from /tmp/vartypes/./vartypes/VarTypesFactory.h:37:0, from /tmp/vartypes/./vartypes/VarTypesInstance.h:17, from /tmp/vartypes/./vartypes/VarTypes.h:42, from /tmp/vartypes/build/vartypes/gui/../../../vartypes/gui/VarItem.h:25, from /tmp/vartypes/build/vartypes/gui/moc_VarItem.cxx:9: /tmp/vartypes/./vartypes/primitives/VarAny.h:27:45: fatal error: boost/archive/binary_iarchive.hpp: No existe el archivo o el directorio compilation terminated.

I have had to install vartypes from google like this:

• I downloaded from page: https://code.google.com/archive/p/vartypes/downloads (vartypes-0.7.tar.gz), and then I did this:
  tar xfz vartypes-0.7.tar.gz cd vartypes-0.7 mkdir build && cd build cmake .. make sudo make install

Are you sure that you'r using ODE with double precision ?

[pabloreyesrobles]

I'm having the same issue. I did "./configure --enable-double-precision --with-trimesh=opcode --enable-new-trimesh --enable-shared -enable-release" before installing, as I saw in other threads assuming that will solve the problem, but I'm still getting the error.
I have Ubuntu 16.04 and recently installed ODE 0.13.

[mahi97]

As I personally tested grSim only on Ubuntu 14.04 and macOS i'm not sure about it, but is seems, as it's happened for the second time, that config files (~.xml) which made by vartypes from the first time cause this error. maybe because language setting or any other related settings.
I will test grSim on 16.04 ASAP.

[mahi97]

I test it on 16.04 lately and i hadn't any problem, can you share your *.xml files here ?

[Anamaria11]

Hola,
What .xml files you need? I dont see .xml files in my grSim folder

[pabloreyesrobles]

@mahi97 I erased the .grsim.xml file on home folder, and I was able to run the simulator again, but got this:

XML Parsing error inside file '/home/pablo/.grsim.xml'.
Error: File not found
At line 0, column 0.

I also got this the first time I ran the the simulator after installed it but I think wasn't important, what could it be? Is it our problem? Sharing my .xml by the way.

grsim.xml.zip

[Anamaria11]

Error is the second time that you run grsim. My .xml file:

.grsim.xml.zip

[pabloreyesrobles]

@Anamaria11 It worked for me! Thank you a lot. I'm fighting with the simulator right now but I have no issues now running it.

[mahi97]

Sorry for late response i was too busy about IranOpen.
I think any error related to xml files can only came from vartypes xml file, but grSim currently work with vartypes 0.8 and vartypes from google code is version 0.7 so I think change form version 0.7 to 0.8 may cause this issue. but I never get this error though so i still thinking that the problem is the way that vartypes save and load data form xml files.

[bermeom]

I solved this problem using a Docker container (it is easy if you have any problem it just restart container) look my repository: https://github.com/bermeom/grSim-docker or https://hub.docker.com/r/bermeom/grsim/

[renatoosousa]

thanks @Anamaria11, it work for me too

(Ubuntu 18.04 LTS and 16.04 LTS) I compiled and installed ODE with the "--enable-double-precision" flag but I got the same error, then, I tried to apply the @Anamaria11 's solution (installing vartypes 0.7) but I couldn't because of problems with c++11, but I found that, if I close grSim, open ~/.grsim.xml and change all the dots by commas (except by "?xml version="1.0" encoding="utf-8"?" and "VarString name="Vision multicast address" 224.5.23.2 /VarString"), it works. But I have to do that every time I want to open grSim.

[renatoosousa]

@edgarcamilocamacho This worked for me too.

[mahi97]

Please test this PR #84.
I Hope this fixes the issue.
