Execute socktap in Cohda SDK #108

Closed KaHartmann closed 4 years ago

KaHartmann commented 4 years ago

Hi,

I would like to build vanetza and socktap for Cohda MK5 using the Cohda SDK. I have followed the instructions and everything looks correct but I cannot execute neither the socktap-hello nor the socktap-cam application.

The error message is: /lib/ld-linux-armhf.so.3: No such file or directory

I found ld-linux-armhf.so.3 in /home/duser/mk5/bsp/kernel/initrd/src/lib and in /home/duser/mk5/bsp/kernel/initrd/src/lib/arm-linux-gnueabihf.

Is the fault due to the cross compilation toolchain?

Thanks in advance.

If you have cross-compiled the executables then you can only run them on the target architecture. You can check with readelf -h <path/to/executable> for which machine type an executable has been built. I guess you are trying to run an ARM binary on a x86-64 machine, which fails naturally.

Okay, thanks for the info. Because of the information on the Cohda website that you can use the SDK to develop, cross-compile and run programs for the cohda, i thought it should work despite different architectures. But don't ask me how :D
