symbols c/c++ link problems

["Wesley Smith" <wesley.hoke@...>]

Hi list,
I'm having some problems with symbol mangling in C++ and linking that
I can't seem to figure out.  I have a C++ template class that uses lua
API functions.  It serves as my base class for userdata modeling. For
some reason though, when I inherit from this class, the lua symbols
used look like this:

 U __Z10luaL_errorP9lua_StatePKcz
         U __Z10lua_gettopP9lua_State
         U __Z10lua_insertP9lua_Statei
         U __Z10lua_rawgetP9lua_Statei
         U __Z10lua_rawsetP9lua_Statei

I've checked and double checked my code and everywhere I include lua
headers I have this:

#ifdef __cplusplus
extern "C" {
#endif

#include "lua.h"
#include "lauxlib.h"

#ifdef __cplusplus
}
#endif

which leads me to believe that the symbol mangling shouldn't be
happening.  There aren't any weird compilation settings.  Here's the
GCC call:

/usr/bin/gcc-4.0 -x c++ -arch i386 -pipe -Wno-trigraphs
-fpascal-strings -fasm-blocks -g -O0 -fmessage-length=0
-mfix-and-continue -Wno-deprecated-declarations -Wno-invalid-offsetof
-mmacosx-version-min=10.4 -DLUA_USE_MACOSX -D__MACOSX_CORE__ -lpthread
-isysroot /Developer/SDKs/MacOSX10.4u.sdk -c luaOfTexture.cpp -o
luaOfTexture.o

Any ideas?

thanks,
wes
