I compiled the "sample_hello_word.cpp " on my host pc ,then i used “scp” command to send the binary file “sample_hello_word” to my target machine . It does not work and print the error “cannot execute binary file:Exec format error”

Dear @FYJ,
I think you have not cross compiled the sample. If so, please see the instructions at https://docs.nvidia.com/drive/driveworks-3.5/dwx_samples_building_V5L.html

Dear @SivaRamaKrishnaNV , I followed the link that you gave to me step by step, and the step 3 .3 as shown below(I have no PDK now). I still can not run the sample on target machine and print the error “cannot execute binary file:Exec format error”

Hi, @FYJ
Your command has some typos. Please double-check and try again.

Dear @VickNV there are some typos when converting images to text , because I can’t upload my screenshots .One thing that can be confirmed is that my command is correct.

Dear @FYJ,
Could you share the logs of -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=/path/to/driveworks/samples/cmake/Toolchain-V5L.cmake -DVIBRANTE_PDK:STRING=/path/to/drive-t186ref-linux -DTRT_VERSION:STRING=6.3.1.3 /path/to/driveworks/samples/folder and make -j12 to see what is the issue. If the compilation is successful, the build folder is expected to have all binaries

Dear @SivaRamaKrishnaNV , I have no PDK now, I can not do the command “-DVIBRANTE_PDK:STRING=/path/to/drive-t186ref-linux”. Is this why I can not cross compile?

9

Dear @FYJ,
I can not do the command “-DVIBRANTE_PDK:STRING=/path/to/drive-t186ref-linux

Does that mean, you don’t have drive-t186ref-linux folder on host? If so, you can not cross compile the sample in that case. To cross compile DW sample on host, You need to install DRIVE Release on host and also you need to select flashing target option in sdkmanager to have all neccessary things installed for cross compilation.

10

Dear @SivaRamaKrishnaNV , I have no drive-t186ref-linux folder on host, I followed the guide step by step to install all necessary things. “You need to install DRIVE Release on host and also you need to select flashing target option in sdkmanager to have all neccessary things installed for cross compilation”&“-DVIBRANTE_PDK:STRING=/path/to/drive-t186ref-linux”, Does that mean I have to install PDK on my host ,then i will have the drive-t186ref-linux folder on host?

11

Dear @FYJ,
If you install DRIVE release on host using sdkmanager, it should be at ~/nvidia/ . Could you check what you see in that path?

12

Dear @SivaRamaKrishnaNV , here is my path list:

Dear @FYJ,
Please check DRIVE_OS_5.2.0_SDK_Linux_OS_DRIVE_AGX_XAVIER folder contents for drive-t186ref-linux folder. If you don’t find, Please check re-installing using sdkmanager

14

Please try if the below command works on your side.

$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=/usr/local/driveworks/samples/cmake/Toolchain-V5L.cmake -DVIBRANTE_PDK:STRING=$HOME/nvidia/nvidia_sdk/DRIVE_OS_5.2.0_SDK_Linux_OS_DRIVE_AGX_XAVIER/DRIVEOS/drive-t186ref-linux -DTRT_VERSION:STRING=6.3.1.3 /usr/local/driveworks/samples

15

Dear @VickNV thanks a lot, I will try that later.

16

Dear @SivaRamaKrishnaNV thanks a lot, I have re-installed using sdkmanager, I find the folder now.
