I've been trying to compile gem5.opt for x86, using both the unmodified
gem5-stable repo (with 'scons build/X86_SE/gem5.opt') and the unmodified
gem5 repo (with 'scons build/X86/gem5.opt'). I've tried on gcc 4.3.2,
4.5.2, and 4.6.1, and in all cases the build fails when it gets to
decoder.cc after a very long time. The error is always something like:
[ CXX] X86/arch/x86/decoder.cc -> .o
build/X86/arch/x86/decoder.cc:120069:3: fatal error: error writing to -:
Broken pipe
compilation terminated.
g++: Internal error: Killed (program as)
Please submit a full bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
scons: *** [build/X86/arch/x86/decoder.o] Error 1
scons: building terminated because of errors.
I've seen several other related errors on both the users and dev mailing
list, but I haven't seen any solutions. On the dev list, I saw a discussion
about splitting decoder.cc into several files, so that gcc could compile
it, but I haven't come across any followup.
Does anyone have an techniques for getting past this point in the compile?
Thanks,
Max
Other system details:
The system has 8GB memory
Red Hat (Enterprise 4)
Python 2.6.7
Are you able to compile gem5.fast or gem5.debug? It definitely seems like
gcc runs out of memory while compiling. Try compiling on a machine with
more memory / swap space if you can.
