Glib cannot be built statically on Windows because glib, gobject and gio modules need to perform specific initialization when DLL are loaded and cleanup when unloaded. Those initializations and cleanups are performed using the DllMain function which is not called with static builds. Issue is known for a while and solutions were already proposed but never merged (see: https://gitlab.gnome.org/GNOME/glib/-/issues/692). Last patch is from version 2.36.x and since then the "constructor/destructor" mechanism has been implemented and used in other part of the system. This patch takes back the old idea and updates it to the last version of glib to allow static compilation on Windows. WARNING: because DllMain doesn't exist anymore in static compilation mode, there is no easy way of knowing when a Windows thread finishes. This patch implements a workaround for glib threads created by calling g_thread_new(), so all glib threads created through glib API will behave exactly the same way in static and dynamic compilation modes. Unfortunately, Windows threads created by using CreateThread() or _beginthread/ex() will not work with glib TLS functions. If users need absolutely to use a thread NOT created with glib API under Windows and in static compilation mode, they should not use glib functions within their thread or they may encounter memory leaks when the thread finishes. This should not be an issue as users should use exclusively the glib API to manipulate threads in order to be cross-platform compatible and this would be very unlikely and cumbersome that they may mix up Windows native threads API with glib one. Closes #692
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.

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.

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.
