Evaluate which application libraries you might want to add after the "../configure ....." stages to support the wine functionality you require...

Thank you for the link. Unfortunately, I could not execute the forth yum install statement because my system did not find any i686 packages in the clearos-centos repo.

If you can't find the packages in the stock repo you can try looking in clearos-centos. Not everything that is CentOS is included in ClearOS because the outcomes and results are experimental. But that is what the community edition is for so run the following to get the 32 library for gcc:

yum --enablerepo=clearos-centos install libgcc.i686

Don't do an upgrade or update with that repo enabled, it will break things.

Also, I don't think there is a gcc.i686 package. If you want to compile with gcc in 32-bit mode, try the -m32 flag.

It seems that repo clearos-centos has no 32-bit packages. Here for example what I get when trying to install libgcc.i686:

I found the 32bit packages in a mirror site here: http://mirror1-orem.clearsdn.com/clearos/7/centos/os/x86_64/Packages/ but I don't know how to update the clearos-centos repo's to include the mirror url.
