Driveworks 1.2 Samples Compilation Error

Hello,

My group is attempting to cross-compile the Driveworks samples provided in 1.2, but are getting an error about constraint graphs from cmake. I don’t fully understand this error and was not there at the time they were working on the cross-compilation but they sent me a screenshot of the error. I’m attaching it here in hopes to get some help in resolving this issue to get the samples compiling for us. Thanks!

Dear bjsmyth,

Could you please help to check the following? Thanks.

  1. Host System Prerequisites part in DriveWorks doc.
  2. CUDA environment set up in bashrc.
  • export PATH=/usr/local/cuda-9.2/bin/:$PATH export LD_LIBRARY_PATH=/usr/local/cuda/targets/aarch64-linux/lib:$LD_LIBRARY_PATH

Hi Steve,

I checked the bashrc and saw the PATH and LD_LIBRARY_PATH were set to cuda-9.0. I updated them to 9.2 and that resolved the issue. Thanks!

Hi Steve,

I get the exact same errors. Unfortunately, this solution did not work for me.

Any other idea what could it be causing this error?

Hi Steve,

I get the exact same errors.

my bashrc is
export PATH=/usr/local/cuda-9.2/bin/:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/targets/aarch64-linux/lib:$LD_LIBRARY_PATH

But the solution is not.

However, it is work well when i execute make command by ignoring the above error.

The executable also works.
Is this an error i can ignore?

We are having the same issue. Is there any update?
