Source SDK Base 2013 Multiplayer previous2021 release fails to execute due to issues with engine.so

As it says on the tin. Default public release works, but not previous2021. This seems to be a constant across installations and distributions based on Arch, so this is an overarching Arch problem.

I cannot parse for the life of me everything else about the topic, and everything else assumes I am missing something vital which I already have installed. However this doesn’t seem to be a problem with older Debians and Ubuntus.

Select Source mods need to use this specific build. Why is this so broken in Arch?

I mean, do you have a specific error message you can share so we can see the exact details?

It is possible it is looking for some older libraries that are no longer present on Arch but we would need a lot more details including the exact error message and where you got the software in question from.

Was doing a bit of reading and came across this here on github and maybe it can help or point you the right direction.

Build created by following documentation initially fails to run

I have followed instructions for building on Linux however: `game/mod_tf` doesn'…t exist instead `game/mod_tf_linux64` exists, this is probably just a simple mistake by whoever documented it. Running that file yields an error that it fails to `load interface VCvarQuery001 from engine.so`. The issue deceptively lies with `libcurl-gnutls.so.4`, something somewhere related to the engine wants that library but cannot find it. Placing version `4.7.0` from Sniper Runtime somewhere in the dynamic linker's path, such as: `Source SDK Base 2013 Multiplayer/bin/linux64/libcurl-gnutls.so.4` fixes the issue and the game launches. I suspect this could be an issue with the launcher forgetting a library path.

Have fun parsing this log.

Yes, I am using linux-cachyos-bore as kernel. But that surely can’t be the problem… right?

A minor breakthrough; my instance of EndeavourOS uses GlibC 2.43, while Linux Mint uses 2.39. Perhaps it’s a missing filename issue in /var/lib I can resolve with a symlink?
