How to compile an extension against specific glibc version(2.13 in my case)?

[Powerlord]

If you're getting GLIBC issues during runtime for extensions, for a lot of games it means that the extension was linked against server.so and vstdlib.so instead of server_srv.so and vstdlib_srv.so.

I tried to copy libvstdlib_srv.so and libtier0_srv.so into hl2sdk-l4d2/lib/linux and then remove _srv from filenames.
Nothing changed.

How to link these libraries properly?

[Powerlord]

If you're compiling it using a Makefile, the "easy" route would be to update the Makefile where it says libtier0 to libtier0_srv and where it says libvstdlib to libvstdlib_srv

Note that this is the "easy" fix. The proper fix is to rewrite the Makfile to only do this change if the game is css, tf2, dods, hl2dm, or l4d2.

And finally it compiled.

Thanks.
