With gcc, I suppose you should be looking for the compiler version
使用 gcc，我想你应该寻找编译器版本
gcc -v
Perhaps in combination with the version of libgomp
也许结合libgomp的版本
ls -ltr /usr/lib/libgomp.so.1*
e.g.
例如
-rw-r--r-- 1 root root 46652 2010-09-27 23:00 /usr/lib/libgomp.so.1.0.0
-rw-r--r-- 1 根 46652 2010-09-27 23:00 /usr/lib/libgomp.so.1.0.0
Depending on your distro this might give more info:
根据您的发行版，这可能会提供更多信息：
dpkg --status libgomp
E.g:
例如：
Package: libgomp1
Status: install ok installed

In my case it confirms that the version matches gcc

Quoting from the GCC wiki pagecontaining information on the OpenMP specification:
引用包含 OpenMP 规范信息的GCC wiki 页面：
As of GCC 4.2, the compiler implements version 2.5 of the OpenMP specification, as of 4.4 it implements version 3.0 and since GCC 4.7 it supports the OpenMP 3.1 specification. GCC 4.9 supports OpenMP 4.0 with the follow exceptions (as of 2013-11-28): the new 4.0 directives are not yet supported in Fortran and omp targetwill always run on the host
从 GCC 4.2 开始，编译器实现了 OpenMP 规范的 2.5 版，从 4.4 开始，它实现了 3.0 版，并且从 GCC 4.7 开始，它支持 OpenMP 3.1 规范。GCC 4.9 支持 OpenMP 4.0，但有以下例外（截至 2013 年 11 月 28 日）：Fortran 尚不支持新的 4.0 指令，omp 目标将始终在主机上运行
