Gem files will remain installed in /home/dev/.local/share/gem/ruby/3.2/gems/tiktoken_ruby-0.0.5 for inspection.

I see it's aware of OpenBSD's clang and clang++ which is great. For those who don't know, OpenBSD's has its own rewrite alternative of almost everything, including make.

Anybody know what to do?

[basicfeatures]

pkg_add llvm seemed to do the trick.

[basicfeatures]

Actually that was not at all how. But I found a temp workaround, maybe leave this issue open until we have a real solution?

$ ruby -v
ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-openbsd]
$ uname -sr
OpenBSD 7.3

$ gem install --user-install tiktoken_ruby
[...fails...]
$ doas pkg_add gmake
$ export LIBCLANG_PATH=/usr/local/lib/
$ gmake
$ doas gmake install

Nasty!

[basicfeatures]

Found the way:

make=gmake LIBCLANG_PATH=/usr/local/lib gem install --user-install tiktoken_ruby
