SHMAT problem; IPC config?

[Chris Conn]

Hello to all,

I am attempting to use programs I compiled with the GNU GCC 2.8.1 package 
downloaded from www.sunfreeware.com.  The GIMP imaging tool, among others, 
indicates during startup that a "shmat" failed.  I tried editing the 
/etc/system file to increas the amount of available shared ram from 1Mb to 4Mb 
and this does not change anything.  I am quite sure this is an IPC problem.  
Here is the output of ipcs:

IPC status from <running system> as of Fri Aug 20 07:55:33 1999
Message Queue facility not in system.
T         ID      KEY        MODE        OWNER    GROUP
Shared Memory:
m          0   0x50018b13 --rw-r--r--     root     root
m        601   00000000 --rw-rw-rw-    cconn    staff
m        602   00000000 --rw-rw-rw-    cconn    staff
m       3003   00000000 --rw-rw-rw-    cconn    staff
Semaphores:

I wonder what does "Message Queue facility not in system" mean?  Does this 
indicate that my system does not support it (SS20/64Mb/Solaris 2.6), or do I 
need to tweak the config to activate/enable IPC?  Or is it simply a GCC 
problem (not supported?)

Thanks in advance,

Chris
