Supported platforms
|
||
===
|
||
|
||
GLib’s approach to portability is that we only support systems that we can test.
|
||
That means that either a large number of GLib developers are regularly using
|
||
GLib on a particular system, or we have regular builds of GLib on that system.
|
||
|
||
Minimum versions
|
||
---
|
||
|
||
* macOS: minimum version OS X 10.7 (we
|
||
[don’t support universal binaries](https://bugzilla.gnome.org/show_bug.cgi?id=780238);
|
||
some features (like notification support)
|
||
[require OS X 10.9](https://bugzilla.gnome.org/show_bug.cgi?id=747146)
|
||
* Windows:
|
||
[minimum version is Windows 8](https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1970),
|
||
minimum build chain is Visual Studio 2012
|
||
* Static builds are only supported with MinGW-based toolchains (cf
|
||
[this comment](https://gitlab.gnome.org/GNOME/glib/-/merge_requests/2384#note_1336662))
|
||
* Android: [minimum NDK version 15](https://gitlab.gnome.org/GNOME/glib/issues/1113)
|
||
* Linux: glibc newer than 2.5 (if using glibc; other forms of libc are supported)
|
||
|
||
Tested platforms
|
||
---
|
||
|
||
GLib is regularly built on at least the following systems:
|
||
|
||
* GNOME OS Nightly: https://os.gnome.org/
|
||
* Fedora: http://koji.fedoraproject.org/koji/packageinfo?packageID=382
|
||
* Ubuntu: http://packages.ubuntu.com/source/glib2.0
|
||
* Debian: https://packages.debian.org/experimental/libglib2.0-0
|
||
* FreeBSD: https://wiki.gnome.org/Projects/Jhbuild/FreeBSD
|
||
* openSUSE: https://build.opensuse.org/package/show/GNOME:Factory/glib2
|
||
* CI runners, https://gitlab.gnome.org/GNOME/glib/blob/main/.gitlab-ci.yml:
|
||
* Fedora (34, https://gitlab.gnome.org/GNOME/glib/-/blob/main/.gitlab-ci/fedora.Dockerfile)
|
||
* Debian (Bullseye, https://gitlab.gnome.org/GNOME/glib/-/blob/main/.gitlab-ci/debian-stable.Dockerfile)
|
||
* Windows (MinGW64)
|
||
* Windows (msys2-mingw32)
|
||
* Windows (Visual Studio 2017, and a static linking version)
|
||
* Android (NDK r23b, API 31, arm64, https://gitlab.gnome.org/GNOME/glib/-/blob/main/.gitlab-ci/android-ndk.sh)
|
||
* FreeBSD (12 and 13)
|
||
* macOS
|
||
|
||
If other platforms are to be supported, we need to set up regular CI testing for
|
||
them. Please contact us if you want to help.

|
||
Policy and rationale
|
||
---
|
||
|
||
Due to their position in the market, we consider supporting GNU/Linux, Windows
|
||
and macOS to be the highest priorities and we will go out of our way to
|
||
accommodate these systems, even in places that they are contravening standards.
|
||
|
||
In general, we are open to the idea of supporting any Free Software UNIX-like
|
||
system with good POSIX compliance. We are always interested in receiving
|
||
patches that improve our POSIX compliance — if there is a good POSIX equivalent
|
||
for a platform-specific API that we’re using, then all other things equal, we
|
||
prefer the POSIX one.
|
||
|
||
We may use a non-POSIX API available on one or more of our supported systems in
|
||
the case that it provides some advantage over the POSIX equivalent (such as the
|
||
case with `pipe2()` solving the `O_CLOEXEC` race). In these cases, we will try
|
||
to provide a fallback to the pure POSIX approach. If we’ve used a
|
||
system-specific API without providing a fallback to a largely-equivalent POSIX
|
||
API then it is likely a mistake, and we’re happy to receive a patch to fix it.
|
||
|
||
We are not interested in supporting other systems if it involves adding code
|
||
paths that we cannot test. Specifically, this means that we will reject patches
|
||
that introduce platform-specific `#ifdef` sections in the code unless we are
|
||
actively doing builds of GLib on this platform (ie: see the lists above). We’ve
|
||
historically accepted such patches from users of these systems on an ad hoc
|
||
basis, but it created an unsustainable situation. Patches that fix
|
||
platform-specific build issues in such a way that the code is improved in the
|
||
general case are of course welcome.
|
||
|
||
Although we aim to support all systems with good POSIX compliance, we are not
|
||
interested in adhering to “pure POSIX and nothing else”. If we need to add a
|
||
feature and we can provide good support on all of the platforms that we support
|
||
(above), we will not hold back for other systems. We will always try to provide
|
||
a fallback to a POSIX-specified approach, if possible, or to simply replace a
|
||
given functionality with a no-op, but even this may not be possible in cases of
|
||
critical functionality.
|
||
|
||
Specific notes
|
||
---
|
||
|
||
Note that we currently depend on a number of features specified in POSIX, but
|
||
listed as optional:
|
||
|
||
* [`CLOCK_MONOTONIC`](http://pubs.opengroup.org/onlinepubs/009695399/functions/clock_gettime.html)
|
||
is expected to be present and working
|
||
* [`pthread_condattr_setclock()`](http://pubs.opengroup.org/onlinepubs/7999959899/functions/pthread_condattr_setclock.html)
|
||
is expected to be present and working
|
||
|
