You don=E2=80=99t want that; llvm-devel is snapshots of LLVM=E2=80=99s = development branch. You want just llvm, which is the latest officially released version, if you need a package at all, which I doubt is actually the case (see below). > This worked fine on FreeBSD/amd64 inside Virtual Box but not for = FreeBSD/RISC-V in QEMU: >=20 > pkg: No packages available to install matching 'llvm-devel' have been = found in the repositories >=20 >=20 > So is there really no llvm-devel port available for FreeBSD/RISC-V? Indeed, depending on what repo you want, there is currently no version of that built, nor recent released versions of LLVM, due to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D261374. The bug has been fixed but as far as I can tell no recent rebuild has happened for the 14 latest repo, only the 13 quarterly repo. > Another thing that caught my attention is, that freshports.org never = seems to mention any RISC-V availability. I thought that with FreeBSD 13 = the RISC-V architecture moved to Tier-2 support ( = https://wiki.freebsd.org/riscv#Current_Status ).

Just asking =E2=80=A6 RISC-V is self-hosting via the in-tree toolchain, thus no external toolchain is required, and thus no official binary packages are required to be provided. Out of the box you can compile with Clang and link with LLD, no packages needed. You only need the packages if you need a different specific version or you need to use = libLLVM/libClang=E2=80=99s APIs.
