If I call "mex hello.f", I get the message:
/Applications/MATLAB_R2009aSV.app/bin/mex: line 992: gfortran: command not found

However, I can use gfortran to compile functions from the command line.

Any idea what the problem is? Does mex have its own path variable?
My gfortran is located at /usr/local/bin/gfortran

I'm running Matlab R2009a on my mac x86 with OS 10.6.

I had a similar problem until I hard-coded the gfortran path as below. This was for R2009b/64-bit, but a similar solution may work for your.

% Compiler settings for R2009b 64-bit Mac OS X: %
-----gfortran:-----
I used this version http://r.research.att.com/gfortran-4.2.3.dmg instead of the experimental version for Xcode 3.2.

-----Xcode:-----
http://developer.apple.com/technology/xcode.html


-----Matlab Mex options:-----
Here's the modificatins to the maci64 section from my 'mexopts.sh' file. There was a problem with it using the wrong libgfortranbegin when building a 64-bit mex until I hard-coded the correct path. BTW, you may want to clear out the '/usr/local/lib/' directories before re-installing gfortran.

# To use the gfortran compiler, which must be installed separately,
# include the following modifications to the 'maci64' section of the
# '~/.matlab/R2009b/mexopts.sh' file

# -----Modifications by D.Jones, Sep-2009:--------------------
FC='/usr/local/bin/gfortran'
FC_LIBDIR='/usr/local/lib/'
FC_LIBDIR2='/usr/local/lib/gcc/i686-apple-darwin8/4.2.3/x86_64/'
FOPTIMFLAGS='-O5 -funroll-loops -ftree-vectorize'
# ------------------------------------------------------------

# Note that gfortran installs its libraries in ‘/usr/local/lib/’

Robert,
Did you run mex -setup and choose the fortran compiler?

No, but you need to set up the internal matlab environment
variables to recognize the compiler. You do that by using the

mex -setup

command from the matlab command prompt, *provided* matlab
has already been set up to recognize the compiler.

Be aware that the -setup option only works for a number
of pre-selected compilers, so there might be more hacking
required.

If I run mex -setup, I get only two options. Choosing either one gives the same error reported above.

I'll try Dave's hack.
