Age of Wonders III fails to start: undefined symbol pthread_yield
Hello @osce0, this issue should also be mentioned to the game's dev(s).
Here is a request to game dev: https://support.paradoxplaza.com/hc/en-us/requests/247198
Thank you.
I can confirm the issue on Gentoo Linux x86_64 (after having recently upgraded to glibc-2.34). I can also confirm that the workaround described in this forum post works.
The idea is to create a shim pthread_yield with contents:
extern int sched_yield(void);
int pthread_yield()
{
return sched_yield();
}
compile it with gcc -m32 -shared -fPIC pthread_yield.c -o pthread_yield.so, copy this into the AoW3 folder (next to AoW3Launcher.sh) and modify the latter by adding the following right before the exec line
# preload shim for >=glibc-2.34
export LD_PRELOAD="pthread_yield.so"
After this, the game starts up normally, although I haven't tried playing yet, as figuring this out took over my playing time...
@chdoc I followed your instructions but I get an "wrong ELF class: ELFCLASS32)" error when I compile it with gcc -m32 -shared -fPIC pthread_yield.c -o pthread_yield.so:
ERROR: ld.so: object 'pthread_yield.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

If I compile it with gcc -m64 -shared -fPIC pthread_yield.c -o pthread_yield.so I get a similar error but now with the undefined symbol like when I provide no pthread_yield.so at all:
ERROR: ld.so: object 'pthread_yield.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.

I use fedora 37 with glibc 2.36-9.fc37.
do you have any hints for me?

Crosscompiling is not easy, probably you need the libgcc-dev for i386 and probably gcc-multilib installed.
On latest linux mint i had installed today: gcc-multilib libgcc-11-dev:i386

you can just run it through a proton, then everything works

I'm guessing something to do with the game not compatible with newer glibc-2.34-25 that separates out pthread. I wonder if re-packaging with detecting newer glibc and doing workaround will fix this.
