openblas:build_lapack should use gfortran from CCI #13169

Library name openblas packages

Openblas relies on system gfortran compiler for building with the option build_lapack, which on many systems may not available out of the box
This PR changes openblas recipe to use gfortran from conan-center-index
Additionally update the recipe to use conan V2

I've read the guidelines for contributing.
I've followed the PEP8 style guides for Python code in the recipes.
I've used the latest Conan client version.
I've tried at least one configuration locally with the conan-center hook activated.


          use conan fortran with build_lapack option

I believe gfortran is a build requirement, does not it? You want fortran to build lapack only.

ggulgulia Sep 27, 2022

that is true. I should use build_requires I suppose there.

          use fortran as build requirements

I'm still not able to build openblas with lapack after the modifications. When I run the command

conan create path/to/openblas/conanfile.py 0.3.17@user/testing -o openblas:build_lapack=True

I get an error indicating that fortran compiler is not found

From our previous discussion on simbody MR, I conclude that we cannot change the option build_lapack=True in the recipe to test if this works on conan-center-index CI

I would assume there's some hint or path check and we need to give the CMake the location of the compiler?

  source_subfolder/CMakeLists.txt:73 (include)

I would assume there's some hint or path check and we need to give the CMake the location of the compiler?

Likely, gfortran needs to be installed. Otherwise, CMake documents setting the Fortran compiler here. Use the FC environment variable or the CMAKE_Fortran_COMPILER cache variable.

Wow, I had no idea we had a gfortran Conan package. Oh... it's a binary package. Bummer. Yeah, setting the environment variable should work for Autotools, too, per the documentation here.

@jwillikers There is a long history behind gfortran package. It was totally broken for many months, then we converted to a pre-built tool recipe.

I think the gfortran package is still broken as per #14120, even after making the necessary modifications to export FC to the build environment. I've had limited success on linux building lapack using the gfortran executable build with the gcc as updated in #13896 but this still won't be useful for modifying the default option until the gcc recipe supports both windows and macos as well.
