I try to cross compile an application (not a driveworks sample) to run after on AGX DRIVE but I keep getting this error:

Dear @mohammed.el-yaagoubi,
Do you see the file in relavant path? May I know what library sample you are trying to build?

4

I try to do the cross compilation of an open source framework for deep learning called N2D2 (GitHub - CEA-LIST/N2D2: N2D2 is a open source CAD framework for Deep Neural Network simulation and full DNN-based applications building.).
And yes I can see the file in the relevant path

5

Dear @mohammed.el-yaagoubi,
It looks like a include path issue. Please double check if the aarch64-linux-gnu/python3.6m/pyconfig.h is in include path?

When I try to change the folder containing the pyconfig.h file I get this error:
