Re: [photran] How to build a Windows DLL from a fortran code with
|
Okay I played with it a little bit and figured it out. Once you have an automatic makefile project ready,go to Project->Properties->Fortran build->Settings.
Under the Tools Settings tab select Miscellaneous under GNU Fortran Linker and add
"-shared -mrtd" to the Linker Flags box. Then go over to the Build Artifact tab
and set the Artifact extension to .dll (I had to type it in). Set a prefix if
desired and you are ready to build a .dll.

Subject: [photran] How to build a Windows DLL from a fortran code with

Dear photran users and developers,
I recently got a 72 ko fortran code full of subroutines that is usually
transformed into a Windows DLL by Lahey Fortran 90 (using DLL_EXPORT
lines in the code)
Could anyone tell me how I could do the same with photran ?
(I already tried using a "shared library type" project, with MinGW GCC
tool chain and could get foo.o (once the DLL_EXPORT were commented
out...), but the later command
gfortran -o foo.dll foo.o
does complain about "undefined reference to `MAIN__' which is normal
since there is no main program.
Under Linux I would think I would have had a ranlib or ar line instead
of this gfortran line...
It is the first time I try to build a Windows DLL so that I do not know
the specific flags/steps to build a dll.
