I am trying to do a cross compilation of driveworks samples following this https://docs.nvidia.com/drive/driveworks-3.5/dwx_samples_building_V5L.html but I keep getting this error :

Hi, @mohammed.el-yaagoubi
Is /home/melyaagoubi/nvidia/nvidia_sdk/DRIVE_OS_5.2.0_SDK_Linux_OS_DRIVE_AGX_XAVIER/DRIVEOS/drive-t186ref-linux/ the right directory? Were the target components installed successfully via SDK Manager ?
Have you cross-compiled successfully before?
DriveWorks 4.0 was released. Would you like to move to DRIVE OS 5.2.6 and DriveWorks 4.0?

4

Yes AGX DRIVE is the right target and all the components were successfully installed via SDK Manager.
I have already done a cross-compilation before.
No I would like to keep DRIVE OS 5.2.0 and DriveWorks 3.5

5

I haven’t seen the failure. Could you figure out why it worked before?

6

It is the first time I get this error. Should I define the path with export CMAKE_MAKE_PROGRAM ?

7

I don’t think it’s necessary.
I would think about why last time didn’t have the error.
Was the last successful build done on the same host?

8

Yes it was done on the same host. I can do a compilation but it is the cross compilation that causes problems

Please remove the line ending slash of your DVIBRANTE_PDK path in your command and try again.

change from:
/home/melyaagoubi/nvidia/nvidia_sdk/DRIVE_OS_5.2.0_SDK_Linux_OS_DRIVE_AGX_XAVIER/DRIVEOS/drive-t186ref-linux/
to:
/home/melyaagoubi/nvidia/nvidia_sdk/DRIVE_OS_5.2.0_SDK_Linux_OS_DRIVE_AGX_XAVIER/DRIVEOS/drive-t186ref-linux

Does it solve your problem?
