9.2 Version numbers
You can find the version number of
gcc using the version
$ gcc --version gcc (GCC) 3.3.1
The version number is important when investigating compilation problems, since older versions of GCC may be missing some features that a program uses. The version number has the form major-version.minor-version or major-version.minor-version.micro-version, where the additional third "micro" version number (as shown above) is used for subsequent bug-fix releases in a release series.
More details about the version can be found using
$ gcc -v Reading specs from /usr/lib/gcc-lib/i686/3.3.1/specs Configured with: ../configure --prefix=/usr Thread model: posix gcc version 3.3.1
This includes information on the build flags of the compiler itself and the installed configuration file, ‘specs’.
