[petsc-users] error with xlib

[Mark Adams]

Now that I look at it, I see:

CFLAGS="-fstack-protector -fno-stack-check -Qunused-arguments -O2 -g
-Xpreprocessor -fopenmp -I"$(brew --prefix libomp)/include" -L"$(brew
--prefix libomp)/lib -lomp""
prefix="/Users/markadams/Codes/petsc/arch-macosx-gnu-O-omp"

Note the two ". That does not look right. I use

'COPTFLAGS=-O2 -g  -Xpreprocessor -fopenmp -I"$(brew --prefix
libomp)/include" -L"$(brew --prefix libomp)/lib -lomp" ',

I know how to do stuff like:

'--with-blaslapack-lib=-L' + os.environ['OLCF_NETLIB_LAPACK_ROOT'] +
'/lib64 -lblas -llapack'

Is there like and os.exec that I could use like this for my FLAGS?
