Build Issue

[Mohammad Wasfi]

Hello, 

I am trying to link the chrono-projects branch to Chrono and I am able to configure and generate with any problems. However, I get the following error in the attached picture when I try to make it. I am using (cuda/11.6.0, and eigen/3.4.0-gcc-11.2.0). 

Thank you, 

[Radu Serban]

Mohammad,

 

Could you please confirm the compiler and compiler version you are using? Not sure if it is GCC-11.2, or if that is part of your eigen installation name.

 

Also, when configuring chrono-projects with CMake enable CMAKE_VERBOSE_MAKEFILE and then post here the full compile command where the error occurs.

 

Thanks,
Radu

Hi Ruda,

Yes, I am using GCC/11.2.0.

I have enabled the CMAKE_VERBOSE_MAKEFILE and attached is the error I see on the screen. Not sure if that is what you meant by "the full command" but I just took a screen shoot of the entire screen. 

Thank you,

Mohammad,

 

Please make sure you pull the latest Chrono code in the ‘main’ branch of the repository, then reconfigure with CMake and rebuild.  I had fixed this issue a while back, but you are likely using an older version of the Chrono code.

 

To make sure you have the fix, once you reconfigured Chrono with CMake, look at the file cmake/ChronoConfig.cmake in your *build* tree.  Starting at line 71, it should contain something like:

# Collect compiler and linker flags in CMake lists!

string(REGEX REPLACE "[ \t]+" ";" CHRONO_CXX_FLAGS " -pthread -fopenmp -march=native")

string(REGEX REPLACE "[ \t]+" ";" CHRONO_C_FLAGS " -pthread -fopenmp -march=native")

string(REGEX REPLACE "[ \t]+" ";" CHRONO_LINKER_FLAGS "")
