Editing Installation of FLUKA (section)

==== Step 3:  Install the appropriate i686 libraries ====

With g77, FLUKA will compile the needed binaries in 32-bit mode, even though one might be on a x86_64 (i.e 64-bit) system.  Thus, it will look for 32-bit libraries at the linking stage, which probably are not installed (by default).  Note that one should install the appropriate i686 version of whichever glibc-devel 64-bit libraries are installed.  You can find out which version is installed on your system with:

<syntaxhighlight lang="bash">
rpm -qa | grep glibc-devel
</syntaxhighlight>

For the jlabdaq system, version 2.12 is installed.  Thus, the appropriate command to install the i686 libraries is:

<syntaxhighlight lang="bash">
sudo yum install glibc-devel-2.12-1.149.el6.i686
</syntaxhighlight>
