Hi! As far as i know, it'll work for CS 1.5. But tested only under Windowz. Not sure about linux hlds of CS 1.5. If not, can you please PM me a link with hlds for cs 1.5, i will fix the probs.
Try:
https://yapb.jeefo.net/drop/releases..._latest.tar.xz (build 4305) I have removed GLIBC_2.15 dependency, it's should run ok. If not, give me "ldd yapb.so" output.
@Storm: yapb is not linked with libstdc++ dynamically nor statically
