Folks,
I am new to rosetta and new to scons so kindly be patient.
From rosetta commons tiki I read:
"(**) Rosetta will crash if optimization level on GCC is greater that -O1."
I am building rosetta-2.3.0 like this:
scons arch=x86 arch_size=64 cxx=gcc bin mode=release extra=mpi
My system is selecting optimization level –O3. I get an executable and there are no errors yet trying to work the test examples gives me segmentation faults.
I read in the scons 0.94 and 1.2 User guides that I can set env variables
“env = Environment(CC = 'gcc',
CCFLAGS = '-O2') “
I have not yet figured out in which of the various rosetta SConscript files to add such a change.
Can anyone tell me how to get scons to tell gcc to use –O1 optimization?
Thanks,
Starr
