This suggestion from Paul has led to a nice file named libproj.a.
When used in combination with a sample program based on the
bit of code shown on the Proj site under proj_api (the code
contains errors!!) this library shows its power: it works!
Then Fortran. With some help from people from comp.lang.fortran
I managed to construct a so-called Module that should interface
with the C-functions pj_init_plus and pj_transform in libproj.a.
The module compiles and produces object code. Even my sample
Fortran program compiles, but it refuses to link: the sample
program calling pj_init_plus cannot find routine pj_init_plus.
Does anyone have a suggestion of how to proceed?
Once I'll have a working Fortran sample, I'll post the solution
to this list anyhow.
