 +==== Issues with POS ====
 +
 +When running XDAQ, one might observe problems on SLC5 when loading shared libraries:
 +''cannot restore segment prot after reloc: Permission denied''
 +
 +Usually SELinux is enabled on SL(C)5 machines and there are 2 cases so far in which one can run into this problem.
 +One needs to disable SELinux by doing as root:
 +
 +''echo 0 > /selinux/enforce''
 +
 +Alternatively, but not working for me, you can get a warning message instead of crash if you set ''SELINUX=permissive'' inside
 +
 +''/etc/selinux/config''
 +
 +You might also run into this problem when loading a library compiled on local disk you might get "error: cannot restore segment prot after reloc: Permission denied". In that case most probably the reason is that either the library or the one which it was linked against need to be rebuild with "-fPIC" option. The SELinux context on AFS does not permit library relocations so sometimes you might hit the problem on local disk but not on AFS or vice versa.

 +
 +==== Issues with XDAQ ====
 +
 +When running XDAQ on SLC6 64-bit and trying to compile my own package, the following error occured:
 +
 +''/opt/xdaq/include/toolbox/net/UUID.h:18:23: error: uuid/uuid.h: No such file or directory''
 +
 +Could be fixed by installing package: ''libuuid-devel''
