Linking with gnu libstdc++ using no%Cstd option

Question

Has anybody had success using (compiling and linking with) the GNU libstdc++ C++ standard library? This would be excluding the use of the Sun supplied Cstd library by using the compile option -library="no%Cstd".
If so please provide any key details.
I'm just trying a very simple test program:
#include <string>
int main(int argc, char** argv) {
string s = "Hello";
The command line to compile is: CC -library="no%Cstd" -lstdc++ test.cc
Many many compile errors follow. Curiously enough it doesn't seem to find the standard includes at /usr/include, even if I explicity specify in the compiler options.
Thanks.

This isnt going to happen. You would have to use -I to point CC at the gcc std header files. They are not going to compile with CC. Furthermore, CC and g++ use different mangling algorithms, so even if you got it to compile, the mangled names that CC emitted would not match the symtab entries in the gcc standard library shared object. And if you managed even more magic to get past this, you would discover that nothing ran, because CC and g++ use different ABI's, i.e. the mechanism by which g++ would propogate an exception would be incomprehensible to code generated by CC, etc. This is actually the underlying reason why the mangling algorithms differ - to explicitly prevent mixing compilers and libraries. Its a sad fact about C++, but you've got to use the same compiler all around, unless you limit yourself to a strict subset at the .so boundry, which is how COM gets around this.
