[rhn-users] installing g++ on my RH desktop

[Peter C. Lai]

On rhel5 here is what I have for a working c++ compiler:

[root at trac1 httpd]# rpm -qa | grep gcc
gcc-c++-4.1.2-42.el5
libgcc-4.1.2-42.el5
gcc-4.1.2-42.el5

(still on 5.2 not upgraded to 5.3...)

[root at trac1 httpd]# yum search gcc-c++
gcc-c++.i386 : C++ support for GCC
gcc-c++.i386 : C++ support for GCC
