This is a Heroku buildpack for FORTRAN-77 apps. Apps need to be compiled using the included f2c FORTRAN to C tranlator. It uses Make.
Example usage:
$ ls
Makefile myapp.f
$ heroku create --stack cedar --buildpack http://github.com/martinrehfeld/heroku-buildpack-f77.git
$ git push heroku master
...
-----> Heroku receiving push
-----> Fetching custom buildpack
-----> f77 app detected
-----> Fetching f2c binaries
-----> Setting up build environment
-----> Compiling with Make
f2c myapp.f
gcc -o myapp myapp.c -lf2c
The buildpack will detect your app as FORTRAN-77 if it has the file Makefile in the root.
It will then run make to compile the app (see examples/Makefile for a template).
