[gate-users] geant4 installation question

[ayanas at mail.med.upenn.edu]

Hello,
I have a problem with GEANT4/OpenGL installation on a Xeon CPU machine running
RHEL4. I posted this question to geant4 discussion list but so fat have not
received any response yet. So I am writing here in case others GATE-users
experienced the same problem.

GEANT4 compiles fine w/o any problem. however when I try to test the G4
installation with an example , say N01, during the linking face I get the 
errors as:

---------------------------------
Compiling exampleN01.cc ...
Using granular libraries ...
Linking exampleN01 ...
/usr/X11R6/lib64/libGL.a(glthread.o)(.text+0x17): In function `_glthread_InitTSD':

: undefined reference to `pthread_setspecific'
collect2: ld returned 1 exit status
-------------------------------------------------------
 

I would appreciate any suggestions as to what I need to do to solve this problem .
Thanks,
