[Solved] FlexiBLAS -- Cmake cannot find modules

[tkzv]

Last time I needed BLAS for compilation, I simply switched between packages with eselect.

Today I tried to build whisper.cpp and got an error:

Code: Select all

$ cmake build
...
-- Adding CPU backend variant ggml-cpu: -march=native 
CMake Warning at ggml/src/ggml-blas/CMakeLists.txt:9 (find_package):
  By not providing "FindBLAS.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "BLAS", but
  CMake did not find one.

  Could not find a package configuration file provided by "BLAS" with any of
  the following names:

    BLASConfig.cmake
    blas-config.cmake

  Add the installation prefix of "BLAS" to CMAKE_PREFIX_PATH or set
  "BLAS_DIR" to a directory containing one of the above files.  If "BLAS"
  provides a separate development package or SDK, be sure it has been
  installed.


CMake Error at ggml/src/ggml-blas/CMakeLists.txt:84 (message):
  BLAS not found, please refer to
  https://cmake.org/cmake/help/latest/module/FindBLAS.html#blas-lapack-vendors
  to set correct GGML_BLAS_VENDOR

In the past I simply used eselect, but now it's been phased out in favor of flexiblas. I tried running «GGML_BLAS_VENDOR="FlexiBLAS" cmake build», but got the same error. How do I set up compilation now?

Update: I tried that again today and everything worked. Since then, I updated dev-build/cmake
to 4.1.4, sys-devel/gcc to 14.3.1_p20260213, kde-frameworks/extra-cmake-modules to 6.23.0 and sci-libs/openblas to 0.3.31. Same sci-libs/flexiblas-3.5.0, as before. The problems may or may not had been caused by incompatible libraries in /lib64 left after hardware failure recovery.

Code: Select all

qfile -o $(find /bin /sbin /lib* /usr/{bin/,games/,include/,lib*/,sbin/,x86_64-pc-linux-gnu/} -mtime 150 -type f)

I see app-accessibility/whisper-cpp in ::guru where they set:

Code: Select all

src_configure() {
        # Note: CUDA and HIP are currently untested. Build failures may occur.
        # Turning off examples causes errors during configure
        # -DWHISPER_BUILD_TESTS=$(usex test)
        local mycmakeargs=(
                -DWHISPER_BUILD_EXAMPLES=ON
                -DGGML_BLAS=$(usex blas)
                -DGGML_CLBLAST=$(usex opencl)
                -DGGML_CUBLAS=$(usex cuda)
                -DGGML_HIPBLAS=$(usex hip)
                -DGGML_VULKAN=$(usex vulkan)
                -DWHISPER_SDL2=$(usex sdl2)
        )
        cmake_src_configure
}

app-accessibility/whisper-cpp in ::guru

It gives the same error, if I enable blas.

Besides, this ebuild does not use ffmpeg, and the resulting program cannot work with AAC or Opus.

Which version of extra-cmake-modules are you running?

Which version of extra-cmake-modules are you running?

Same for kde-frameworks/extra-cmake-modules-6.20.0 and 6.22.0.
