How do I check my gcc C++ compiler version for my Eclipse?

Question

I'm using Eclipse release version 3.7.0, but I can't find the gcc anywhere. How and where can I see the version of gcc I'm currently using?

Answer 1

Just type

gcc --version

in any terminal near you.. ;-)

Answer 2

gcc -dumpversion

-dumpversion Print the compiler version (for example, 3.0 ) — and don't do anything else.

The same works for following compilers/aliases:

cc -dumpversion
g++ -dumpversion
clang -dumpversion
tcc -dumpversion

Be careful with automate parsing the GCC output:

• Output of --version might be localized (eg to Russian, Chinese, etc.)
• GCC might be built with option --with-gcc-major-version-only . And some distros (eg Fedora ) are already using that
• GCC might be built with option --with-pkgversion . And --version output will contain something like Android (5220042 based on r346389c) clang version 8.0.7 (it's real version string)

Answer 3

#include <stdio.h>

int main() {

  printf("gcc version: %d.%d.%d\n",__GNUC__,__GNUC_MINOR__,__GNUC_PATCHLEVEL__);
  return 0;
}

Answer 4

The answer is:

gcc --version

Rather than searching on forums, for any possible option you can always type:

gcc --help

haha! :)

Answer 5

you can also use gcc -v command that works like gcc --version and if you would like to now where gcc is you can use whereis gcc command

I hope it'll be usefull
