@hacksd: I had a look at the gtest issue, and I assume the following is happening: Trilinos brings its own version of gtest, hence the conflict with gtest. However, during build an existing gtest installation is required (in my case, the already installed trilinos package provides it). I'll figure out if this can be solved, but since disabling gtest works it's not on my list of priorities

I have disabled pyTrilinos in this package to have no dependency on python or python2. From https://trilinos.github.io/pytrilinos_faq.html, it seems that python3 is not supported. I also remember vaguely that even python2 (SWIG) caused problems. Also note that current gtest depends on python2.

Once gtest 1.10 (currently in testing) is available, I will see if trilinos works with a system-wide gtest.

I can't successfully build Trilinos with LTO - has anyone else experienced that issue? I don't think LTO will help much with this project anyway since it compiles so many interdependent libraries.

Hi @MartinDiehl Could you please add the option -D Zoltan_ENABLE_F90INTERFACE=ON to generate the module interface file?

I need it to link the Zoltan library in the package elmerfem-git. You will probably also need to add -D CMAKE_C_FLAGS="$CFLAGS -Wno-error=incompatible-pointer-types" to allow compilation. Many thanks for considering my request.

Please don't hardcode the amount of build parallelism with --parallel 4. If you want to enforce parallelism, it is best to add ninja to makedepends and -G Ninja to CMake's configure flags, otherwise just leave it up to users to define their MAKEFLAGS environment variable as they like.

For me, seems strange the following output

$ldd /usr/lib/libkokkosalgorithms.so
        statically linked

Also is possible to add provides=(kokkos).

Edited 2023-07-10: This patch allow bump version to 14.2.0. And works with deal.II 9.5.0 or later. 14.0.0 does not work with 9.4.2 due libkokkos shared/static object issue.

Hi, could you add

provides=(zoltan)

@petronny Same for me

Hi, I have a small request: I made an AUR package called trilinos-sacado which only compiles sacado because I needed it for something else (I mostly took inspiration from yours).

Could you perhaps add a provides=('trilinos-sacado') to your PKGBUILD? Many thanks in advance!

Hello Martin, Trilinos is now at version 13.2.0 I just updated the PKGBUILD

Please could you update? Thanks Regards Gianluca

python-numpy and swig should be added to dependencies, the package does not build otherwise.

But even when I added the packages, the build failed in the end:
