Problem with compilation order?

[IsaMammadli]

Hi,
I added new subroutine in math/operators.f90 called rotate_cyc and I include this in multiple places like fluid_pnpn.f90, fluid_volflow.f90 , flow_ic.f90 etc. When I do make install, I am getting error given in the picture

I guess this might be due to operators.mod not being available at the time flow_ic is compiled. When I remove (comment out) these lines in flow_ic.f90 the compilation finishes and then I put them back in and make install again, it finishes succefully and works as expected. Interestingly this doesnt happen for any other files location in fluid directory.

I was wondering if there is more direct way of doing it by (e.g. changing compilation order) in make files?

Hej,

Check the 'build system' section in the docs: https://neko.cfd/docs/develop/d1/d5a/contributing.html

I think that, as you say, Neko just does not know that it needs to operators when compiling. This can be fixed by running 'make depend'. Give that page a read and try to do as instructed. Hopefully it should work afterwards.

Thank you! Very useful source.
I did a quick fix by adding math/operators.lo line to dependencies of fluid/flow_ic.f90 in src/.depends file.
