Ich stehe gerade vor einem kleinen Problem,
Ich habe vor Lazarusprogramme für einen MPI-Cluster zu erstellen.
Leider gibt es nur eine etwas ältere anleitung im Internet:
http://wiki.lazarus.freepascal.org/MPICH" onclick="window.open(this.href);return false;
Dieses habe ich soweit durchgearbeitet bis zum Testen eines Laraus-exaples
dort bekomme ich jedoch eine Menge Fehler:

helloworld.lpr(14,1) Error: Error while linking
helloworld.lpr(14,1) Fatal: There were 1 errors compiling module, stopping/home/user/mpich2/lib//libm...
Meine Quelle habe ich wie im Tutorial beschrieben eingefügt:
Könnte der doppelte slash den Fehler verursachen?add the following line to /etc/fpc.cfg
-Fl/home/username/mpich-install/lib
Hat jemand ne Idee wie man den Fehler beheben kann?
Wäre sehr dankbar für schnelle Hilfe =)
