(Transplanted from [hlds_linux]...)
Actually, GCC 3.4 and 4.x have the same ABI. The big change happened 3.3
-> 3.4. I don't know what Valve compiled their current engine versions
with (please tell), but is there a plan to move to one of these versions
(3.4, 4.0, 4.1)? What would the timeframe be?
You may wish to read about the ABIs at
http://gcc.gnu.org/onlinedocs/libstdc++/abi.html. It's the major version
(first number) of libstdc++.so that matters. Since GCC 3.4 (versions of
4.2 and 4.3 are not known yet), they're at major 6.
Oh... and here's a tip: DON'T add "-Wall -Werror -pedantic" to and
remove "-fpermissive" from the CCFLAGS. g++ will hate you. ;-)

This question is better asked on the hlcoders list (subscribe via

the Source engine is compiled with GCC 3.x and GCC 4.x binaries aren't
binary compatible for the C++ ABI.

Hi,
Can someone either point me towards discussion of why the linux_sdk
need to be compiled under GCC 3.?.? I am trying to resolve a
problem with my Battlegrounds 2 server and I don't want to downgrade
my compiler from 4.1.1 . I was able to compile a server under 4.1.1
by simply tweaking two source files lightglow.cpp & mathlib.cpp
Anyone ?
