@swiftscythe what do you think?

Btw I think this package should have a check veryfing if cuda is being used after cmake step and fail if not.

I have used options=( '!lto' ) and CXX=g++-13 CC=gcc-13 cmake ... -DCUDA_HOST_COMPILER=/usr/bin/gcc-13 ... and it seems to compile and work properly.

@AchmadFathoni indeed, using gcc11 works *(see NOTE).

But beyond adding -DCUDA_HOST_COMPILER=/usr/bin/gcc-11 also avoid doing LTO, in the PKGBUILD include the line options=( '!lto' ).

*NOTE:Now we have gcc14 in arch wich cannot compile gcc11. So this can get tricky: 1. with gcc14, build gcc13. 2. Use gcc13 to build gcc11 (GOTCHA: patch the PKGBUILD to use gcc13, see aur comments) 3. Use gcc11 to build dlib-cuda.

Will this package be updated? Package has been marked out of date for some months now. 19.24.2 has been out since May. This PKGBUILD should just do what the dlib AUR package does and get the tarball from the GitHub which is 19.24.2: https://github.com/davisking/dlib/releases/tag/v19.24.2

Additionally, this package isn't erroring when the CUDA test compilation fails which results in building dlib without CUDA

-- Disabling CUDA support for dlib. DLIB WILL NOT USE CUDA

Can these be fixed please?

Add gcc11 as makedepend & add -DCUDA_HOST_COMPILER=/usr/bin/gcc-11 should fix this
