It seems the config/configure.py options -COPTFLAGS, -CXXOPTFLAGS, -FOPTFLAGS
work correctly. That is if you set them then the default optimization is turned
off and what you provide is used. This works with petsc-dev.
If this does not work for someone please send configure.log so we can

Hi Aron,
Thanks for the information...everything is clear now.
Hope you will be back to Ireland soon. Sure the weather can be miserable but
nothing beats a good hike in the rain followed by a good pint of Guinness.
Actually Guinness is pretty good with everything including PETSc coding :-)

Perfect...thanks for the info.

Hi PETSc Users/Developers,
Could someone explain how I can override the default optimization level that
comes with my PETSc build (currently -O). I want to set a more aggressive
optimization level (e.g. -O3) for my compiler (PathScale).
Ideally I would prefer a solution which doesn't involve re
And as a correction to my last email, PETSC_ARCH is a 'global'
environment variable, it along with PETSC_DIR help you coordinate
multiple PETSc installations and builds.

Dear Tim,
I was just in Ireland a few weeks ago, had a great time climbing
Carantouhil and the Pilgrim's Path :D
Have you tried declaring a new $PETSC_ARCH and then overriding the
optimization flags in ./conf/configure? PETSc likes to use the
$PETSC_ARCH flag to maintain all local builds under t

Or you could just do:
./config/configure.py PETSC_ARCH=petsc_linux_o3 COPTFLAGS=-O3
make
