I am a newcomer to fpm and I am trying to build a library project with different options. I am the main developer of the library CrysFML (https://code.ill.fr/scientific-software/crysfml). We use Cmake for building the library with ifort or gfortran for the three platforms Windows, Linux and MacOS with two options: (1) console and (2) using an external library for making GUIs.
I wanted to use something simpler than Cmake to build the library and I came aware of fpm.
I have found that for building console programs fpm is very simple and efficient. However, I had to use a script, invoking fpm with response files and other scripts for renaming files, for handling different compilers and different source files containing the same module name but different content (by automatically renaming before invoking fpm). This is not a problem, but something that I have not found, clearly explained in the documentation, is how to use an external library that is installed locally (*.mod files and library) outside the CrysFML directory. After trying several options using [dependencies] in the fpm.toml file, I never succeeded in building the GUI version of the library CrysFML that uses the commercial Winteracter library.
In the Windows (Linux or MacOS is the same) platform, the (simplified) structure of the two directories is the following
CrysFML
├── Program_Examples
│ └── Subdirectories with different programs
├── rsp
│ └── Directory with different response files
├── fpm.toml
├── make_CrysFML_fpm.bat
├── src
│ └── All module source files
Winter
├── lib.i64 (ifort 64 bits)
│ └── Directory containing *.mod, winter.lib and some *.obj files
├── src
│ └── All interface modules source files
My questions are the following:
What have I to write in the fpm.toml file to make fpm finding the pre-compiled *.mod files of the Winteracter library? The winteracter.mod (within lib.i64) is used by one module of CrysFML when the script for building it is invoked with the appropriate response file.
I have tried to put in the compiler flags the include item “/I…\winter\lib.64” but fpm is always trying to find the source file of the module winteracter which is in “…/…/winter/src”. Is fpm unable to work with pre-compiled objects or mod files?
Thank you in advance for providing some tips.
