segmentation fault running MM5 3.7

Hello,

I got “segmentation fault” on a single CPU run of MM5 3.7.

I use the PGF 6.0.
The linux kernel version is 2.6.9
The processor is: Intel Xeon 3.20GHz.
I set the stack size to be 1GB.

The compiler flags (in configure.user) are as the following:

RUNTIME_SYSTEM = “linux”
FC = pgf90
FCFLAGS = -I$(LIBINCLUDE) -O2 -Mcray=pointer -Mbounds -Mnoframe -byteswapio
##FCFLAGS = -I$(LIBINCLUDE) -O2 -Mcray=pointer -tp p6 -pc 32 -Mnoframe -byteswa
pio -mp
##-Mnosgimp
CPP = /lib/cpp
CFLAGS = -O
CPPFLAGS = -I$(LIBINCLUDE)
LDOPTIONS = -O2 -Mcray=pointer -Mbounds -Mnoframe -byteswapio
##LDOPTIONS = -O2 -Mcray=pointer -tp p6 -pc 32 -Mnoframe -byteswapio -mp
LOCAL_LIBRARIES =
MAKE = make -i -r

Any idea of where to look at? Many thanks!!!

In 64-bits, you also need to add the define flag “-DDEC_ALPHA”.

Hope this helps,

Thank you Matt. I’ve add -DECC_ALPHA and my run was completed.
