Re: [netcdfgroup] 64-bit build with Snow Leopard?

it looks like you are using x-code stuff... I think they are quite broken to compile NetCDF. You might try to upgrade your compiler and autoconf/automake using the MacPorts, that is an independent implementation (not official to osx) similar to 'apt-get', 'emerge', 'yum', 'yast', to install latest version of software to your MAC.

It is available at www.macports.org.
A friend was only able to compile NetCDF (4.2.x) once he used MacPorts to upgrade his compiling environment. The sequence is to install X-Code to get initial compiling environment, and then upgrade the compiler, make, some libraries already present from MacPorts as needed, and then compile NetCDF.

Sorry I can't be much specific to your problem, but I believe this information might help.

Also, I see you have gcc-4.2.1, gfortran is just 4.2. This might be the cause you can't link a file compiled with gfortran to a file compiled with gcc. Although it shouldn't. Regardless of that, I still think upgrading your compiler environment with ports will solve the issue.

I am struggling to build netcdf with snow leopard.

I have read this thread and tried things but am still getting problems.

This is the error I am getting:

Any help is much appreciated. I have looked on the information in this
thread and i am not if when people are referring to the FFLAGS am i changing
it in the .tcshrc for my computer.
