build fails with gfortran on linux (CMAKE)

[fiolj]

Description

Building with CMAKE on fedora 43
with GNU Fortran (GCC) 15.2.1 20251111 (Red Hat 15.2.1-4)
and cmake version 3.31.6

using:

cmake --build build

I'm getting serveral errors on compilation, being the first:

src/stdlib_sorting_radix_sort.f90:16:30:

16 | integer(kind=int_index), intent(in) :: N
| 1
Error: Symbol ‘int_index’ at (1) has no IMPLICIT type

I could not trace yet where is the error. Any help would be appreciated.

Expected Behaviour

Successful compilation

Version of stdlib

34723c7

Platform and Architecture

Fedora 43 Linux

Additional Information

No response

hmmm..., I have no problems on Ubuntu 24.04 wit the following:

$ git status
HEAD détachée sur 34723c7d
rien à valider, la copie de travail est propre

$ cmake --version
cmake version 3.28.3

I will try to add GCC15 to the CI/CD

Thanks Jeremie, it definitely was an error on my end.
It seems as there was some unfinished compilation files around that impeded to rebuild some source files and produced the error. Even after I've cleaned-up the error was still there.

Now, I've got a fresh copy from the repository on a different location and it compiled without problems.

Ignorance from my part: Is there a cmake command to clean-up configuration/compilation files in the build system?
Seems as GCC 15 is working!

Happy to hear that it compiled fine with GCC15.

Ignorance from my part: Is there a cmake command to clean-up configuration/compilation files in the build system?

Maybe the following:

cmake --build build --clean-first

However, in practice, I always remove completely the build directory.

Ok, I don't know if keep commenting here. I'll leave it for future reference.

Removing /build and using --clean-first was not enough to make it work.

Finally it worked by removing manually all objects and module files, i.e: mod_files/ , *.mod, *.smod, *.o

Thanks for the help!
