Hi there!
One of the basic libraries glibc inside hepsw/cvmfs-lhcb is corrupt, missing two files gconv-modules and gconv-modules.cache.
They were installed:
[root@dev workspace]# rpm -ql glibc | grep module
/usr/lib64/gconv/gconv-modules
/usr/lib64/gconv/gconv-modules.cache
but they are not in the folder:
[root@dev workspace]# ls /usr/lib64/g
games/ gio/
That's why there is an error when running some of the LHCb applications:
Could not load a transcoding service
I fixed the problem with: yum reinstall glibc
