[Bug-gsl] Re: [Help-gsl] compiling with gsl on MAC OS X

[Peter Johansson]

Hi Tim,

Please keep list in cc.

If I understand correctly, the problem is that your libgsl is 64-bit and 
your gcc builds 32-bit by default. I'm not sure how to change the 
behavior of your gcc, so I think the easiest path would be to rebuild 
your gsl and configure it for multiple architectures as described in the 
INSTALL file. In short: If you already have a gsl directory issue 'make 
clean' before you configure. Then configure with

 ./configure CC="gcc -arch i386 -arch x86_64" CPP="gcc -E" CXXCPP="g++ -E"

that is you will build a library for both i386 and x86_64

followed by
$ make
$ make install
as usual I think it may work.

Cheers,
Peter
