Programs don't compile after load from dusty-nv/jetson-inference

[steven.sparks]

I’m on ORIN Jetson AGX Developer kit
L4T 35.1.0 [ JetPack 5.0.2 ]

Reading document posted by dusty-nv - jetson-inference/docs/building-repo-2.md
All was successful, until the “Compiling the Project” step.
I executed the $ make command from the jetson-inference/build directory.
Then i see errors during tensorNet.cpp, captureWindow.cpp, and PyNumpy.cpp compile:

Did I miss a step? I assume others have had similar issues?

Thanks for the Help!

I modified the three programs that caused the build to fail. I have not tested the code changes and will do so as I develop. They all now compile at least.

PyNumpy.cpp
jetson-inference/utils/python/bindings/PyNumpy.cpp
Added a new line of code

308   // Initialize NumPy
309  PyMODINIT_FUNC PyNumpy_ImportNumpy()
310  {
311	      import_array();
312       //import_ufunc();    // only needed if using ufunctions
313	      return NULL;         // SPARKS 2023-04-20 Added this line to fix error
314  }

tensorNet.cpp
jetson-inference/c/tensorNet.cpp
Add 20 to cache_path variable length

1212 char cache_prefix[PATH_MAX]; // No change
1213 char cache_path[PATH_MAX + 20];   // Add 20 to length to help compile

captureWindow.cpp
jetson-inference/tools/camera-capture/captureWindow.cpp
Added return

218 // GetWidget
219 glWidget* CaptureWindow::GetWidget( int index ) const
220 {
221	return display->GetWidget(index); // SPARKS 2023-04-20 Added return to fix compaile error
222 }

Hi @steven.sparks, those were warnings not errors, so they shouldn’t have prevented the programs from compiling. Regardless, thanks for tracking these down - is it working for you ok now?

[steven.sparks]

Yes, all is working ok now. Thanks for the quick reply.
