Hi,
I just tried to put openkim-api-v1.4.0 onto my macbook pro and it failed to compile. Here is the offending part of the result:
Hi Ron, Yes. Sorry about that. I should have documented this issue before the release of 1.4.0... Anyway, here is the workaround.
As of 2014-01-20, gfortran on Darwin OS (Mac OSX) has a bug
associated with the use of iso_c_binding Fortran/C
interoperability features which are now standard in openkim-api.
(See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59888) We have
reported this bug and are awaiting its fix. In the meantime,
the following workaround has been identified:
(i) You must have a "multi-library" version of gfortran
installed on your mac due the need (see (ii) below) to
compile for a 32bit architecture. This means that GCC must
have been configured with the "--enable-multilib" flag. To check
your version execute `gfortran -v' and look for the string
"--enable-multilib". In order to install a multilib version
of gfortran on your mac you can use a package manager such
as Homebrew, Mac Ports, or fink. Follow the instructions
for installing the package manager of your choice. Then
execute the command to install gfortran.
For Homebrew the command is:
% brew install gfortran --enable-multilib
For Mac Ports the command is:
% sudo port select --set gcc mp-gcc48
(Note, this may require that you compile the package from source
in order to get the correct version.)
(ii) You must compile the openkim-api and associated Models,
Tests, etc. using the `KIM_SYSTEMARCH = 32bit' setting.
(iii) Item (ii) above, may mean that you will need to tell your
compilers to use 32bit mode (for example):
`CC = gcc -m32'
`CXX = g++ -m32'
`FC = gfortran -m32'
(iv) You need to have the following line in the
Makefile.KIM_Config file in order to avoid harmless
compiler warnings:
`LDFLAGS += -read_only_relocs suppress'
That should do it.... Let's hope the gfortran team gets around to fixing this bug quickly.
Cheers,
Ryan
