Building NVTT failed

[Seleucids]

I am trying to build the latest version of the game, but I encounter nvtt build error when compilling libraries:

$ ./build-source-libs.sh -j28
Building third-party dependencies...
Building CxxTest...
Skipping - already built (use --force-rebuild to override)
Building FCollada...

CMake Error at CMakeLists.txt:1 (CMAKE_MINIMUM_REQUIRED):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.


-- Configuring incomplete, errors occurred!
ERROR: NVTT build failed

I do have cmake installed at version 4.0.0-1:

extra/cmake 4.0.0-1 (12.0 MiB 78.8 MiB) (Installed)
    A cross-platform open-source make system

I tried to build libraries with NVTT included but this error will  occur when i am making:

$ make -j28

@real_tabasco_sauce this problem is preventing me from testing out your patch. This is for the latest A28 source code.

Your Cmake is too recent. You might get away by editing the cmake file for nvtt and change the version there.

Sadly this didn't work and resulted in a cascading follow up errors. I suspect conda environments are the cause and I am going to try to do it with a new system user.

Is that the original .patch file?

Maybe compiling https://gitea.wildfiregames.com/0ad/0ad/pulls/7736 instead will be easier.

@real_tabasco_sauce they haven't reached the point of compiling the game yet. They are building the side libraries.

@Seleucids Python isn't needed for NVTT so it shouldn't be because of conda. If we used another build system like meson for that library it might have, but this is not the case.

@hyperion do you have cmake 4 on Gentoo ?
