Linux version crashes with ./libiggy_linux.so: undefined symbol: pthread_yield

[atomopawn]

The linux version is built against an old version of glibc. Version 2.34 and higher of glibc removes the pthread_yield function this game needs. Instead, programs are supposed to use sched_yield(). A workaround is to compile a "shim" that will create a pthread_yield() function that calls sched_yield() and use LD_PRELOAD to load it.

I am attaching two files I've created that allow you to fix this. To use them, rename pthread_yield.c.txt to pthread_yield.c and compile it with:

gcc -m32 -shared -fPIC pthread_yield.c -o pthread_yield.so

And copy pthread_yield.so to

STEAM_FOLDER/steam/steamapps/common/AoW3/

(or whichever folder your AoW3 files are in)

Then edit AoW3Launcher.sh.txt to add an LD_PRELOAD variable set to pthread_yield.so or copy the AoW3Launcher.sh.txt file over the existing AoW3Launcher.sh file).

Hopefully the publisher will release a patch soon that fixes this issue more correctly.

Thanks for the post! It was quite helpful.

Just a quick note, the external function declaration should really be:

extern int sched_yield(void);

One could also just remove it and uncomment the first line.

Hello. I already have an issue because of this. Is there a proper fix on the way ?

Thank you in advance

 

[keiki85]

Thanks for the workaround. It worked. I thought it continued to stop working because of this, but was because the server are down.

Is AoW3 still being cared for ?

@emmasterakia : Is there any plan for a corrective patch for Linux ?

The fix in the OP worked exactly as advertised. THANK YOU SO MUCH for posting this! I had to go back to my windows partition to play AoW3 for awhile, now I can boot linux everytime again!

Ah that was the last thing I needed to fix the game once and for all on my end.
Thank you so much for the information. Another game will work smoothly.

Thank you very much for the tip!

It's of no use for me now, because my distribution (Mageia 10 stable) keeps with glib 2.32 (rev. 1867065 from 2022/07/01), for some reason.
But I should soon be affected, I guess.

As a side note, in some other occasion, with another game, I had to manually download and install the 32 bit version of a library that is shipped only in 64 bits now by my distribution.

Delightful. Thank you.

Sadly, it doesn't work for me on Gentoo with glibc-2.38.
No error when I run from the shell : sh AoW3Launcher.sh, then nothings !

edit : ok, it works for me too, but as Guest!

Hello guys, i compile a pthread_yield.so for Ubuntu 22.04.

 

[Gagarinten]

And it work for me. I use an Ubuntu22.04
