Dear FOAMers,
Is this possible to compile user-developped OpenFOAM solvers when using OpenFOAM on Windows, with a 'Native-windows' installation? I would need to do so for teaching purposes. Thanks by advance for your help!
All the best,
Laurent

Bonjour!

1/ What compiler (and linker and makefile system) do you intend to use?

2/ Can you copy a solver (e.g. laplacianFoam or simpleFoam) from src/ to a scratch space and try to compile, link and execute there (possibly good to rename solver first)?

3/ How big/complex is the user developed solver?

4/ Does it help to try this on linux first (in case not already done so)?

Bonjour

Thanks for your reply, please find my answers below.

Best regards,

Laurent

1/ What compiler (and linker and makefile system) do you intend to use?
-> I would like to compile a user developed solver with wmake (not sure that I fully understood the question).

2/ Can you copy a solver (e.g. laplacianFoam or simpleFoam) from src/ to a scratch space and try to compile, link and execute there (possibly good to rename solver first)?
-> I did not get in any practical step yet, I am just wondering whether or not it is theoretically possible to compile my homemade OF solvers on a Windows installation of OpenFOAM.

3/ How big/complex is the user developed solver?
-> Nothing really exotic I would say:
https://develop.openfoam.com/Community/hydrology/

4/ Does it help to try this on linux first (in case not already done so)?
-> These solvers do compile on linux systems with OF2206 for instance.

Q1: wmake is a shell around the makefile. wmake in turn calls compiler and linker. It is here where differences between windows and linux become obvious.

Q2: yes, should be possible. The fact that OpenFoam compiles and runs on Native-Windows demonstrates this.

Q3: clear. If not too complex, then yes, again, should work.

Q4: precisely. Do we understand how to adapt the compilation of e.g. simpleFoam and laplacian to your hydrology code? How are simpleFoam and laplacian compiled on Native-Windows using wmake? What are steps that wmake takes? Can these steps be adapted to your hydrology code.

Q5: you will need to adapt https://develop.openfoam.com/Communi...ref_type=heads to your windows system by providing proper definitions of variables like WM_COMPILER and WM_COMPILER_TYPE to your system. The value of these variables can be found using printenv (or similar) on your Windows machine.

Bonne chance. D.

I just read this :

'Native Windows : Cross-compiled Windows binaries (mingw).
Provides a quick means of using OpenFOAM on windows, but does not currently include an OpenFOAM development environment (ie, cannot compile code, no dynamic code)'

My bad, sorry :P
