How do we compile the cpp-interface-vrep from source?

[marcos-pereira]

Hello everyone,

I tried compiling the cpp-interface-vrep from source because I want to to add some new functionalities to it, but some errors occurred when running make after configuring the build with CMake.

I did the following steps:

1. Forked the cpp-interface-vrep.
2. Cloned my fork locally.
3. Copied the files below to the folders coppeliarobotics/include and coppeliarobotics/remoteApi inside the cloned fork folder:

coppeliasim-4-5-1-rev4/programming/legacyRemoteApi/remoteApi/extApi.c
coppeliasim-4-5-1-rev4/programming/legacyRemoteApi/remoteApi/extApi.h
coppeliasim-4-5-1-rev4/programming/legacyRemoteApi/remoteApi/extApiInternal.h
coppeliasim-4-5-1-rev4/programming/legacyRemoteApi/remoteApi/extApiPlatform.c
coppeliasim-4-5-1-rev4/programming/legacyRemoteApi/remoteApi/extApiPlatform.h

4. Made a build folder in the cpp-interface-vrep directory and run CMake:

cd cpp-interface-vrep
mkdir build
cmake -G "Unix Makefiles" ../
make

When running make the following error occurs:

cpp-interface-vrep/coppeliarobotics/include/extApi.h:12:14: fatal error: simLib/simConst.h: No such file or directory
   12 |     #include <simLib/simConst.h>
      |              ^~~~~~~~~~~~~~~~~~~
compilation terminated.
make[2]: *** [CMakeFiles/dqrobotics-interface-vrep.dir/build.make:76: CMakeFiles/dqrobotics-interface-vrep.dir/src/dqrobotics/interfaces/vrep/DQ_VrepInterface.cpp.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/dqrobotics-interface-vrep.dir/all] Error 2
make: *** [Makefile:136: all] Error 2

Did I forget any step regarding installing additional dependencies?
I found this remote API client side link and also this link.

Any hints on how to compile the cpp-vrep-interface from source?

Kind regards,
Marcos

Hi everyone,

I think I solved the issue in some way. I just copied the simConst.h from the CoppeliaSim directory coppeliasim-4-5-1-rev4/programming/include/simLib/simConst.h to the directory cpp-interface-vrep/coppeliarobotics/include/ and changed the include in the extApi.h to be:

#include "simConst.h"

Now the cpp-interface-vrep compiles without problems.

If anyone has a prettier way of solving this compiling issue, feel free to add to this discussion.

Kind regards,
Marcos
