Hello,
I am trying to implement a custom project using the tutorial steps enlisted. When I generate my project after giving the source, build and Chrono_DIR, I notice that the values of the CXX flags and C flags are as follows 

   CHRONO_CXX_FLAGS (Compiler flags): /DWIN32;/D_WINDOWS;/W3;/GR;/EHsc;-openmp;/arch:AVX2;/arch:AVX;/Zc:__cplusplus;/wd4275

   CHRONO_C_FLAGS (Compiler flags): /DWIN32;/D_WINDOWS;/W3;-openmp;/arch:AVX2;/arch:AVX;;/wd4275

these are getting generated from the ChronoConfig.cmake or ChronoConfig.cmake.install I suppose.

However when I load my solution and my project in VS, I'm seeing this error of command-line error:invalid macro definition (refer attachment below). Unable to resolve it.
 
Thanks,
Shubhankar

Shubhankar,

 

I suspect the problem is that you are setting the compiler flags listed in the variable CHRONO_CXX_FLAGS using obsolete CMake syntax.  Take a look at: https://github.com/projectchrono/chrono/blob/develop/CHANGELOG.md#changed-cmake-project-configuration-script and make sure your CMakeLists.txt uses target_compile_options to set the C++ flags for your project, just like it’s done in the latest version of the code for the template_project example.

 

If this does not fix your problem, please provide more details:

  • Which version of Chrono you are working with
  • What version of CMake you have
  • What compiler version you have

And attach the CMakeLists.txt file for your project.

Radu,

Thanks a lot for pointing me to the solution. I was able to get past the macro errors and get my project running.

Sincerely,
Shubhankar
