G77 Fortran compiler on Intel MacBook?

Does anyone know if G77 works on intel macs? I was using it on my iBook (Power PC) - it was installed using Fink+ X code tools.

I'm trying to get g77 to work on my intel MacBook now but Fink seems to suggest g77 is not available for intels. Has anyone tried this?

Alternatively, are there any other fortran compilers out there that will work on intel macs?

thanks,

You can download the fink g77 source code and compile it.
I think this is going to work.

Ash,

G77 will ot compile on Intel based Macs. G77 needs either gcc3.1 or gcc3.3, which aren't available for Intel. I'm not sure how long it'll take for either of those to be ported over, so don't keep your fingers crossed. Have you tried using f2c (it's available through Fink for intel) to convert Fortran 77 to C? Might help with compiling.

That worked, thanks! I think the executable it produces are for PPC but they still run ok.

However, I am having some problems linking a series of object files. I get this error:

/usr/bin/ld: Undefined symbols:
MAIN_
collect2: ld returned 1 exit status

Does anyone have any insight into what could be causing this? Those object files link perfectly fine on a linux machine. Seems to be something to do with the ld binary??

Yup, g77 isn't gonna build on intel. But fink does have g95 and gcc4 if you want a Fortran compiler.

Ok, I tried using gfortran (which is intel compatible) but still getting this ld error:

/usr/bin/ld: Undefined symbols:
__dsohandle
collect2: ld returned 1 exit status

Many thanks Bill! I'm compiling great using gcc and gfortran (via fink).
