[gmx-users] 64 bit compiling on OS X

[David van der Spoel]

Has anybody succeeded compiling gromacs in 64 bit mode on OS X with 
assembly? The problem is that uname -m returns i386, even though the 
machine is perfectly able to compile 64 bit stuff.

A little bit later I was able to compile like this:
#!/bin/csh -f

setenv CPPFLAGS -I/sw/include
setenv LDFLAGS  "-L/sw/lib -m64"
setenv CFLAGS   -m64
setenv CXXFLAGS -m64
setenv ASFLAGS ""
/Users/spoel/GROMACS/head/gmx/configure 
--prefix=/Users/spoel/software-4.0 --with-gsl --host=x86_64-apple-darwin 
--build=x86_64-apple-darwin --disable-ia32-sse
--disable-ia32-3dnow --disable-x86-64-sse

make install

However, no assembly, and one needs to compile all the dependencies 
(FFTW etc.) in 64 bit mode as well.

Any more tips and fixes?
