Error when compiling RTTI samples

[amoroder]

when I try to compile the RTTI samples with Lazarus 0.9.30 I get the error that it cannot create runtimetypeinfocontrol.o in the directory usr/lib/lazarus/components/rtticontrols. After that lazarus is no more usable and must be killed.
Probably it is because I run lazarus as non root user and don't have the necessary rights.
I started the makefile in this directory as root and the .o file whas created, but If I retry to compile the sample from lazarus it continues to try to recreate the .o file it does not have the rights.

Is there a solution other than run lazarus as root ? I can not give a normal user the rights to write to /usr/lib.
