Sourcemod fails to load for srcds, pthread_cond_clockwait symbol not found #3608
Description
As before, I'm running an Ubuntu 22.04 Docker image on an RK3588 with Box86 compiled to run a Counter-Strike: Source dedicated server with Sourcemod and Metamod. When starting the server, it fails to load Sourcemod, stating that the pthread_cond_clockwait symbol can't be found.
I tried running srcds_run with BOX64_LD_PRELOAD=libpthread.so.0 and LD_PRELOAD=libpthread.so.0 as described here, but still got the same results.
Sourcemod version: 1.12 - build 7221
Metamod version: 1.12 - build 1219
