Your question is off-topic for this list, please send requests for help using or building gcc to gcc-h...@gcc.gnu.org. Please take any follow-up questions to that list, thanks. > According to what I have found in the Internet these errors come when > attempting to link object files compiled with different versions of > gcc.

That will compile the code, but will not link to the C++ runtime library, which causes the linker errors you're getting. This is documented in the manual, which you should read: http://gcc.gnu.org/onlinedocs/gcc-4.4.5/gcc/Invoking-G_002b_002b.html The easiest solution to your problem is probably to use 'g++' for C++ programs instead of 'gcc'
