Hi
I am following this ( jetson-inference/building-repo-2.md at master · dusty-nv/jetson-inference · GitHub ) and trying to build the project. During the cmake ../ command, I am getting below errors:

rocket@ubuntu:~/jetson-inference/build$ cmake ../
-- The C compiler identification is unknown
-- The CXX compiler identification is GNU 7.5.0
-- Check for working C compiler: /usr/bin/cc

CMake Error at /usr/share/cmake-3.10/Modules/CMakeTestCCompiler.cmake:52 (message):
  The C compiler

	"/usr/bin/cc"

  is not able to compile a simple test program.

  It fails with the following output:

Just to give a quick background. I am using the waveshare jetson nano which comes with emmc. I have installed Jetpack 4.6.1 and SDK components using SDK manager and then I have copied all the root filesystem to external usb drive so my jetson is booting up from the usb drive. Everything seems to be working fine so I think this should not create any issue with jetson inference project. Please if anyone can help me resolve this issue. Thanks

Hi @ART97, I haven’t seen this error before and I wonder if it’s somehow related to the filesystem configuration you are using. Have you been able to build any other C programs? This wouldn’t seen an error with jetson-inference persay, but rather your GCC toolchain.

Hi dusty_nv

Let me try to see if I can run and build any C program and then will get back to you.

Thanks

It looks like the c ompiler was creating issue after moving the os from internal memory to external usb drive. I have now moved it from internal to external sd card and everything is fine.

Hi @ART97, ok great - glad that you were able to get it working again!
