Example: Determining the installed version of gcc-c++

To see whether gcc-c++ is installed, query for the gcc-c++ package as follows:
   rpm -qa | grep gcc-c++
If gcc-c++ version 4.1.0 is installed, you will get a result similar to the following output:
   gcc-c++-4.1.0-43.24
Note: On RHEL4U2, YDL, and Y-HPC, both 32-bit and 64-bit glibc-devel and libstdc++-devel packages are required. To ensure that these packages are available before you install the compiler, follow the instruction in Could not determine location of 32-bit or 64-bit GCC (RHEL4U2, Y-HPC, YDL). Do not use the example in this section to verify that these packages are installed because the names of the packages on RHEL4U2, Y-HPC, and YDL are structured so that they have the same name regardless whether they are 32-bit or 64-bit packages. As a result, the output does not indicate whether 32-bit, 64-bit or both packages are installed.
