Cross compiling libgpiod is not working

Dear Toradex,

I cannot compile a C object file for the Colibri IMX6 that includes the library gpiod.h: no such file or directory. The toolchain from the quick-start guide is sourced and gpiod is installed using the package manager (apt) in Ubuntu (the host).

This is the command for compiling the code:
${CC} test_program.c -o test_program -lgpiod

And as output I get:

fatal error: gpiod.h: No such file or directory
 #include <gpiod.h>
          ^~~~~~~~~
compilation terminated.

In the gcc command it’s specific library is also linked using “-lgpiod” like this, and works for the host machine.
$gcc test_program.c -o test_program -lgpiod

Hi

Toolchain you are using perhaps doesn’t include ligpiod.a library and gpiod.h header. Perhaps there’s an easy way solve it, but I’m using instead armhf toolchain from Ubuntu. Then I just add missing part like this.

sudo apt install libgpiod-dev:armhf

Hello,

Thank you for your response, I think this might be the solution, I had the library installed for my host computer which is 64 bit. So your solution might work.
