Yes, thank you. It works for me on my Thinkpad T450s with HD Graphics 5500. I wonder if that's also true for AMD and nvidia users. ___ freebsd-ports@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"

Nope. Mesa uses LLVM library ABIs which provide NO stability guarantees so we can not publish them as part of the release without locking the branch to a single LLVM version for the 5-year life (we effectively tried that with 10.x, it was terrible with many ports requiring workarounds for the increasingly obsolete base compiler). If you want to save space here, help out on the subpackage work so you only need to depend on the libraries. https://reviews.freebsd.org/D16457 -- Brooks signature.asc Description: PGP signature

See https://wiki.freebsd.org/WhyDoIHaveToBuildLLVMWhenIAlreadyHaveClangInstalled The long-ish answer is that software graphics rendering and a few other use cases require LLVM libraries not included in base. Base only includes enough to make clang, lld and lldb function, that's it. -- Charlie Li …nope, still don't have an exit line.

mesa-dri's Makefile.common has:

That could be. Maybe someone from x11@ knows more.

devel/llvm80 port on 12.1
I'm trying reduce the size of the NomadBSD image and the biggest installed package is devel/llvm80 with 848 MiB. llvm80 is a dependency of graphics/mesa-dri which is needed for x11-servers/xorg-server. Looking at the llvm version of 12.1-RELEASE in base I see that it is the same version like the installed port: $ /usr/bin/clang --version FreeBSD clang version 8.0.1 (tags/RELEASE_801/final 366581) (based on LLVM 8.0.1) Target: x86_64-unknown-freebsd12.1 Thread model: posix InstalledDir: /usr/bin $ /usr/local/llvm80/bin/clang --version clang version 8.0.1 (tags/RELEASE_801/final) Target: x86_64-portbld-freebsd12.0 Thread model: posix InstalledDir: /usr/local/llvm80/bin So it looks like on 12.1 the mesa-dri port can use the base llvm instead of the one from ports and save all people running Xorg almost 1 GB of disk space? -- Lars ___ freebsd-ports@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
