Questions tagged [g++]
g++ is the C++ frontend to the GNU Compiler Collection (GCC). It's the de facto standard compiler for C, C++, Go, Fortran, and Ada on Linux and supports many other languages and platforms as well. Apart from the compiler, GCC has a toolchain (libc, libstdc++, objdump, nm etc.) that is widely used on several platforms and systems.
