Well as far I can tell the sandbot.so that I've recompiled appears to be linked with only '/usr/lib/i386-linux-gnu/libstdc++.so.6', if my amateur C++ skilled mind doesn't deceive me:-
Code:
desktop@na:~/steamcmd/hlds/gearbox/dlls$ ldd sandbot.so
linux-gate.so.1 => (0xf777d000)
libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf76bd000)
libstdc++.so.6 => /usr/lib/i386-linux-gnu/libstdc++.so.6 (0xf75b1000)
libgcc_s.so.1 => /lib/i386-linux-gnu/libgcc_s.so.1 (0xf7594000)
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf73e3000)
/lib/ld-linux.so.2 (0xf777e000)
libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf739c000)
It doesn't appear to be linked to 'usr/lib/i386-linux-gnu/libstdc++.so.6.0.24' from my server. I am not sure but I think that most Metamod Addons, as well as HL1 Bots seem to adapt better with GCC/G++ 4.8.
Also I got bad news my old Linux Laptop died a couple weeks ago. So I had to install the Debian Jessie i386 Netboot into VMWare and install DropBox where I've kept the src files.
