==== 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.

=== curlpp ===

  cp -r /usr/include/curlpp/ $BUILD_HOME
in ''$BUILD_HOME/curlpp/internal/global.h'' change
  #include "curlpp/config.h"
to
  #include "curlpp/config.h.in"


==== 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''
