Installing CAMB on Sierra

Post by Damian Sowinski » February 24 2017

I'm having problems with getting CAMB working on Sierra.

First off, I have the latest version of gfortran installed

Code: Select all

GNU Fortran (GCC) 6.3.0
Copyright (C) 2016 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
The latest version of pyCAMB says that it fixed the compilation issue with 6.3, but theres another post (http://cosmocoffee.info/viewtopic.php?t ... ht=install) where someone was having problems with 6.3.

When I run from inside the camb/pycamb folder:

Code: Select all

sudo python setup.py install --user
,
I get the following error:

Code: Select all

mkdir -p Releaselib
gfortran -shared -fPIC -O3 -fopenmp -ffast-math -fmax-errors=4 -JReleaselib -IReleaselib/ -c constants.f90 -o Releaselib/constants.o
FATAL:/opt/local/bin/../libexec/as/x86_64/as: I don't understand 'm' flag!
Running through the code, I see that the setup.py starts the subprocess "make camblib.so".
That ends up running Makefile, which gets to the end and starts running Makefile_main.
When gfortran ($(F90C)) is called in the line ,

Code: Select all

$(DLL_DIR)/%.o: %.f90
	$(F90C) $(SF90FLAGS) -c $*.f90 -o $(DLL_DIR)/$*.o
the error pops up.

If anyone know why this is happening, please let me know.
After trying to get around this I finally took Caldwell's advice and installed gfortran v5.3.
Running setup.py no longer pops us the 'm' flag error, but now I get a strange:

Code: Select all

gfortran -dynamiclib -fPIC -O3 -fopenmp -ffast-math -fmax-errors=4 -JReleaselib -IReleaselib/ -c utils.F90 -o Releaselib/utils.o
/var/tmp//ccijfDb9.s:9224:suffix or operands invalid for `movq'
/var/tmp//ccijfDb9.s:9328:suffix or operands invalid for `movq'
make: *** [Releaselib/utils.o] Error 1
looking a the traceback, the problem appears to be in the setup.py file:

Code: Select all

    101             subprocess.call&#40;"chmod 755 Releaselib/camblib.so", shell=True&#41;

SystemExit&#58; Compilation failed
At this point I gave up.
If anyone can help with either the prior issue or the present one, that would be great.

As with that post, it's probably an issue with your gfortran/gcc/ports installation, e.g. cf

https://github.com/Homebrew/legacy-home ... sues/45258
https://github.com/SciRuby/nmatrix/issues/406

If you have problems I'd just compile and run it in one of the CosmoBox virtual environments instead.
