So I am trying to do cross compiling of dw samples using the tutorial here:
https://docs.nvidia.com/drive/driveworks-3.5/dwx_samples_building_V5L.html

But I am getting an error as:

-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:16 (project):
  The CMAKE_C_COMPILER:

    /../toolchains/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.

The command I used was:

ai@ai-PC:~/nvidia/dw_samples/build-agx$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=/usr/local/driveworks-2.2/samples/cmake/Toolchain-V5L.cmake -DCVIBRANTE_PDK:STRING=/home/ai/nvidia/nvidia_sdk/DRIVE_Software_10.0_Linux_OS_DRIVE_AGX_XAVIER/DRIVEOS/drive-t186ref-linux .. -DTRT_VERSION:STRING=6.3.1.3 /usr/local/driveworks-2.2/samples/src

this thread talks about the same problem:

But I tried re-flashing using nvidia SDK manager, but to no avail, any help will be appreciated. Thanks.

I am fairly new to NVIDIA, Drive and making these topic threads, if I should have created this thread somewhere else, feel free to let me know I will delete/close it and re-ask somewhere else.

Hi, @praveen.p.kumar
Was it due to the typo? Could you compare the command provided in the other topic you pointed out?

Yes, I am so sorry!!! i will be very careful next time. Thank you.
There is another error though, perhaps I should start another thread for it, or can we address it here?:

Error below:

CMake Error at cmake/ResourcesConfiguration.cmake:35 (message):
  Combination of TRT version 6.3.1.3 and PDK version 5.1.6.1 not supported
Call Stack (most recent call first):
  CMakeLists.txt:30 (include)
4

how can I check which version of TRT is supported for which version of PDK?

It looks you’re using DRIVE Software 10 which has DriveWorks 2.2. For the cross-compiling command, you should refer to /usr/local/driveworks-2.2/doc/nvsdk_html/dwx_samples_building_V5L.html document on your host system (installed along with DRIVE Software 10 by SDK Manager).
It will be similar to the one in the other topic (also based on DRIVE Software 10).
