Can't compile when including <pthread.h> with Rasbpian 11 (bullseye)

[lucasssvaz]

When building the cmake project, after following all instructions and changing the build script to reflect my board, the compilation fails with the following error:

In file included from /usr/include/pthread.h:25,

• Platform: Raspberry Pi Zero W
• OS: Rasbpian OS 11 (bullseye)

One solution I found was reverting the OS back to Rasbpian OS 10 (buster) and getting the required files from the board again. After that the code was compiled without any hassle and worked as intended. Both installations were fresh and with all packages updated to the latest version. I also found another user with a similar problem using the toolchain in this forum while trying to compile RtAudio.

Hello,
I have the same issue with Rasbpian OS 11 (bullseye), and I don't a solution yet.
Regards.

Here's a work-around. It contains the root FS which allows for building for bullseye:
