help gcc
« on: June 14, 2007, 01:59:36 pm »
i write C++ sample code, then i compile with C:\PROGRA~1\CODEBL~1\bin>"mingw32-gcc.exe" -o helo.exe hello.cpp -Wno-deprecated
so appears :
C:\DOCUME~1\user\LOCALS~1\Temp/ccKEaaaa.o:hello.cpp:(.text+0xd): undefined reference to `std::string::size() const'
C:\DOCUME~1\user\LOCALS~1\Temp/ccKEaaaa.o:hello.cpp:(.text+0x60): undefined reference to `std::string::operator[](unsigned int) const'

Use g++ or mingw32-g++ instead of mingw32-gcc.

This question is barely Code::Blocks related -- and at any rate, C::B knows how to compile your program better than you do, so why aren't you using it?
