intl is complicated to look up. Some of that complexity now resides in
Meson, since 0.59.0, via a `dependency('intl')` lookup, so use that
instead.
The Meson lookup doesn't include all the checks here, but likewise this
meson.build doesn't include all the checks in Meson. Particularly, the
following are different:
- Meson accurately detects support built into libc, even if that
conflicts with an external library version (which should be detected as
broken and thus not-found, but glib does not do so).
The problem here is that depending on which libintl.h header is first
in the search path, the *gettext symbols may be the libc ABI, or they
may be renamed to libintl_*gettext, then additionally take over the
*gettext names via a macro, in order to invoke the external library
version even on systems where there is a libc builtin. This means that
checking for `cc.has_function()` correctly reports that there is such
a function in libc, but that unfortunately does not mean it is usable,
because source code referencing `ngettext` etc. will expect to be
linked to `libintl_ngettext`.
- glib checks whether the found intl requires pthread, rather than
simply trusting the result of `cc.find_library()` for the external
library case.
Do the heavy lifting by using Meson to check for intl, and select the
correct implementation, but do a post-discovery check if the symbol is
linkable both with/without pthread.
The logic is still a bit hairy, and eventually more of the logic could
be moved into Meson. But it's better than before.
Fixes incorrect detection of intl on musl-based systems (which have a
less capable libc intl), when GNU libintl is installed as an external
library.
GLib
GLib is the low-level core library that forms the basis for projects such as GTK and GNOME. It provides data structure handling for C, portability wrappers, and interfaces for such runtime functionality as an event loop, threads, dynamic loading, and an object system.
The official download locations are: https://download.gnome.org/sources/glib
The official web site is: https://www.gtk.org/
Installation
See the file 'INSTALL.md'
Supported versions
Only the most recent unstable and stable release series are supported. All older versions are not supported upstream and may contain bugs, some of which may be exploitable security vulnerabilities.
See SECURITY.md for more details.

Discussion
If you have a question about how to use GLib, seek help on GNOME’s Discourse
instance. Alternatively, ask a question
on StackOverflow and tag it glib.
Reporting bugs
Bugs should be reported to the GNOME issue tracking system. You will need to create an account for yourself. You may also submit bugs by e-mail (without an account) by e-mailing incoming+gnome-glib-658-issue-@gitlab.gnome.org, but this will give you a degraded experience.
Bugs are for reporting problems in GLib itself, not for asking questions about how to use it. To ask questions, use one of our discussion forums.
In bug reports please include:
- Information about your system. For instance:
- What operating system and version
- For Linux, what version of the C library
- And anything else you think is relevant.
- How to reproduce the bug.
- If you can reproduce it with one of the test programs that are built
in the
tests/subdirectory, that will be most convenient. Otherwise, please include a short test program that exhibits the behavior. As a last resort, you can also provide a pointer to a larger piece of software that can be downloaded.
- If you can reproduce it with one of the test programs that are built
in the
- If the bug was a crash, the exact text that was printed out when the crash occurred.
- Further information such as stack traces may be useful, but is not necessary.
Contributing to GLib
