How to add pthreads to pkg-config

[Nikolaus Rath]

Hello,

How do I add pthreads when generating the pkg-config file?

I tried:

threads = dependency('threads')
# ...
pkg = import('pkgconfig')
pkg.generate(libraries: [libfuse, threads],
version: meson.project_version(),
name: 'fuse3',
description: 'Filesystem in Userspace',
subdirs: 'fuse3')

but this fails with "Library argument not a library object nor a string."

If I omit "threads" from the "libraries" argument, the .pc is generated
fine, but the -lpthread argument is missing in the "Libs" line.

Thanks,
-Nikolaus

Strings are passed through directly, so libraries : [libfuse,
'-lpthread']. This is not the greatest of UIs, but unfortunately the
way threading works on different platforms is one huge Rube Goldberg
machine. :(

Hmm. Ok. Is this also the only solution for libraries found with
.find_library() (like 'dl')? I wasn't able to pass them to
pkg.generate() either.


Best,

It is. We should probably do something about that...
