Unable to link libpthread on Mac OS 14.2.1 and Apple M2 chip

Hi, I am trying to configure a model, but FlexibleSUSY is not able to find libpthread. I see that you already fixed this bug for version 2.4.0, so maybe this issue is related to the previous one?

Here is the terminal output:

Error: libpthread must be installed to enable multithreading!

Please let me know if you need further input from my side.

Thank you!

Dear @michelelucente ,

thanks for reporting this issue!

Could you please search for libpthread* on your machine? Maybe it is not installed or located in a directory where FlexibleSUSY does not search.

Alternatively, you could also disable multi-threading by ./configure --disable-threads. Then FS will not search for the threads library. :)

Best regards Alex

Hi Alex, I found the origin of the issue. libpthread seems to have a different name on my machine, the library is libsystem_pthread.dylib.

So I solved the issue by creating a symlink with the standard library name:

sudo ln -s /usr/lib/system/libsystem_pthread.dylib /usr/local/lib/libpthread.dylib

It works now.

Thank you for helping with that!

Ah, excellent solution! :) Anyway, thanks for reporting!
