The open64 compiler binaries are 32bit type or i686 type. So you would need to have support for 32bit binaries.
You will find this documented at: 22.214.171.124. Using 32-bit compilers on a 64-bit host
While installing these package you may face yum package installer errors.
By default yum expects to have \var folder, if its not there it will complain. So we are modifying cachedir variable to point to a path that is correct and valid.
I would suggest to create one folder in your home e.g. /home/alvaro/yumcache (presuming your home is /home/alvaro )and modify /etc/yum.conf following way.
cachedir=/home/alvaro/yumcache/<keep the rest path as is>
Then go to the “System” menu on the Top bar and select “Administration” and then “Add / Remove Programs”. Search the package name with name alone i.e. excluding arch type e.g. glibc-devel
You will have to install all the three packages. glibc-devel.i686 libgcc.i686 libstdc++-devel.i686
You can do this one by one: 1. glibc-devel 2. Libgcc 3. libstdc++-devel
When you search for above packages in the “Add Remove window”, it will show both x86_64 and i686 packages suffixed accordingly. Make sure you select i686 packages.
