Re: [Brahms-dev-l] PROOF with your own library

Hello.  This is an additional comment to the previous instruction.  As I 
found out, the instruction is correct.  (It actually works.)   But, you 
need to be carefull with SETUP.C file since in the PROOF session, your 
include path is not correct.  For PROOF to compile your code (meanning 
you do "set->Process("yourcode.C+") ), it needs to know header files of 
your library.  You can specify your include path by 
gSystem->SetIncludePath("-I/path_to_header") in your SETUP.C.
