I know very little about linux.
I need to update gcc to at least 4.4 for xbt install
when I do
yum install boost-devel gcc-c++ mysql-devel subversion
I get Finished
Setting up Install Process Package boost-devel-1.33.1-16.el5_9.i386 already installed and latest version
Package gcc-c++-4.1.2-54.el5.i386 already installed and latest version
No package mysql-devel available.
yum install gcc44-gfortran
yum install gcc44-c++
but still gcc version 4.1.2
CentOS release 5.7 (Final)
