I’m following the cross-compiling instructions but got the following error:

nuc4agx@nuc4agx-NUC8i3BEK:~/build$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=/usr/local/driveworks/samples/cmake/Toolchain-V5L.cmake -DVIBRANTE_PDK:STRING=/home/nuc4agx/nvidia/nvidia_sdk/DRIVE_OS_5.2.6_SDK_Linux_OSWithSamples_DRIVE_AGX_XAVIER/DRIVEOS/drive-t186ref-linux /usr/local/driveworks/samples

That works fine (my original post had a syntax error in VIBRANTE_SDK).
However, the actual make fails because libbsd.so.0 not found:

... warning: libbsd.so.0, needed by /usr/lib/aarch64-linux-gnu/libXdmcp.so.6, not found (try using -rpath or -rpath-link)

Any suggestion?

Hi, @user28207

Please compare your command to the below one from the document page you pasted. Thanks.

I’ve added TRT_VESRION option but it didn’t help:

I was able to build everything by copying libbcd,0* from ${VIBRANTE_PDK}/targetfs/lib/aarch64-linux-gnu/ to ${VIBRANTE_PDK}/lib-target. Not a solution but a hack to move forward.

Good to hear it works on your side. I saw you already fixed the command typo in your first post but I haven’t seen the libbcd,0* issue.

Please help to create another topic for this. Thanks.
