Cross-compile

When I try to cross compile the sample code on host machine, when I type the following command:
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=/usr/local/driveworks-2.0/samples/cmake/Toolchain-V5L.cmake -DCAMKE_PDK:STRING=/home/zhang/nvidia/nvidia_sdk/DRIVE_Software_9.0_Linux_hyperion_E3550/DriveSDK/drive-t186ref-linux …

There is an error:
– The C compiler identification is unknown
– The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:17 (project):
The CMAKE_C_COMPILER:

/../toolchains/tegra-4.9-nv/usr/bin/aarch64-gnu-linux/aarch64-gnu-linux-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.

Dear yu.zhang01,

Recently we’ve post Drive Software 10.0(DriveWorks 2.2).
Could you please update Drive Software 9.0 to 10?

I believe you already know DriveWorks starting guidance and cross-compilation way like below.
However could you please help to check it again?
https://docs.nvidia.com/driveworks/dwx_devguide_getting_started.html
https://docs.nvidia.com/driveworks/dwx_samples_building_V5L.html

Because I could run the command w/o any issue. Thanks.

Dear yu.zhang01,
I notice you have used DCAMKE_PDK:STRING instead of -DVIBRANTE_PDK:STRING in command. Also, the last parameter should point to DW samples folder. Could you check these things?
As Steve said, we recommend upgrading to latest DRIVE SW version to get new features and enhancements.

@SivaRamaKrishna，
oh， I am so careless, Thank you!

Dear yu.zhang01,
Were you able to cross compile or you still have any issues?

6

Yes, I am able to cross compile, thank you.
