Error compiling deepstream-app c files.

[emad555]

I am trying to make few edits on the c files to print more information, when I compile the files using:

CUDA_VER=10.2 make -C deepstream_app, I got the following error:

Makefile:67: recipe for target 'deepstream_app.o' failed
make: *** [deepstream_app.o] Error 1

Even when I removed my lines I still get the same error.

hello I'm curious about this too. Do you know where the deepstream_app.c file is?

[emad555]

@bongpigeon

Now I have edited the files and I am getting the following without errors, but nothing happened:

sudo CUDA_VER=10.2 make deepstream-app make: Nothing to be done for 'deepstream-app'.

You can find the folder here: /opt/nvidia/deepstream/deepstream-6.0/sources/apps/sample_apps

[bongpigeon]

So I'm trying to display the objects that are counted, but I can't display it so I tried to edit the deepstream_app_main.c code but nothing happended. Do you know how to?

[emad555]

I could compile the edited code without errors, but I can't see the changes.

[bongpigeon]

me too.

This is more specific to the NVIDIA sample code. I recommend you to ask in the NVIDIA forums.
