hi:
when I run the deepstream-test1,it met an error such as:
tesco-yu@tescoyu-desktop:~$ cd /opt/nvidia/deepstream/deepstream-5.1/sources/apps/sample_apps/deepstream-test1
tesco-yu@tescoyu-desktop:/opt/nvidia/deepstream/deepstream-5.1/sources/apps/sample_apps/deepstream-test1$ ls

Fatal error: can’t create deepstream_test1_app.o: Permission denied

A regular user does not have permissions to write to content under most system directories. “/opt” is one such location. You could use “sudo” to run the commands, but if possible (to avoid the pitfalls of messing up a system directory) you might first try compiling as your regular user in an alternate location. In the case of the sample apps though I already know the content is not going to interfere, so you might as well just use sudo for the case of the deepstream sample (I would not suggest this with most builds, deepstream sample is an exception).

Thanks for your quick response,I have solved the error when I run the command “sudo CUDA_VER=10.2 make”.
