Hi all,
I have built chapel with following environmental variable for the
debugging mode.
if [ "$1" == "debug" ]; then
echo "Debugging mode on"
export CHPL_DEVELOPER=1
export CHPL_COMM_DEBUG=1
export CHPL_GASNET_DEBUG=1
export GASNET_BACKTRACE=1
export CHPL_DEBUG=1
fi
The chapel compiles with no error. The hello world compiles fine. Then when
I try to compile the lulesh from the benchmark directory I get
In file included from /tmp/chpl-xxxxx-29352.deleteme/_main.c:49:0:

Should I turn off the compiler flag -Werror=maybe-uninitialized? If yes
where is this compiler flag set from?
fyi - gcc-4.9.2
