As the data from meson is no longer relative path, it is not longer
possible to move gst-build around and run gst-uninstalled.py. This broke
cross-compilation usage, where you build on a host and run over NFS on
target. This adds an option to tell the script to strip off the host path
to the sysroot.
When relying on a system-wide libnice, we end up not building
the nice elements, which means we can't use them, and by extension
webrtcbin, in the uninstalled environment.
This also introduces a way to avoid checking the version of
a given subproject, and makes use of it for libnice and pygobject,
which only passed the version check by chance, as its current
major version is 3.
This is needed for using the qmlgl out of the box inside
gst-uninstalled. Of course this won't work if the user is using
a native file to specify the path to `qmake`.
... depending on detected shell program. For instance,
if the nearest ancestor process is PowerShell, run uninstalled
environment via PowerShell. Otherwise, $COMSPEC (most likely cmd.exe)
will be used.
When using a custom prompt the automatic override may not look good, so
provide a mechanism to disable it.
Document that the user will have to use GST_ENV manually when setting
the prompt to have a visual indicator of the gst-uninstalled
environment.
Use an array instead of a dict to make sure we iterate over
the list of subprojects in the right order, which is first
GStreamer core, then gst-plugins-base, then other things.
Without this subprojects might get configured in random order,
in which case gstreamer or gst-plugins-base libs might get picked
up via pkg-config if they are also available installed, instead of
being picked up from the subproject. This breaks all kinds of
assumptions in gst-build and will likely have strange effects
and/or lead to build failures such as
subprojects/gst-plugins-good/tests/check/meson.build:144:2:
ERROR: 'gstreamer-plugins-base-1.0' is not a pkgconfig dependency
Starting with Meson 0.50, meson instrospect --targets uses a list
for the filename and install_filenames of each target. Handle both
lists and strings.
Since gst-devtools checks for gst-rtsp-server and will
happily pick up an external dep which isn't what we want
if we configure it as subproject afterwards.
This assumes meson dicts are always stable, which may
not necessarily be the case, but it seems to work in
practice for now.
See #16
This to simplify the checks made when for example a flex binary
is available system wide: the build process was failing when
that system wide binary didn't have the required version. Instead
of adding more checks and making things more complex, let's just
always use our binary subproject.
libpsl is a dependency if libsoup that has an upstream Meson build
system (in master only).
libsoup also needs libxml2 but we already have a wrap file for it.
The only remaining dependency that must come from the system is sqlite3.
These are example cross files that will be used by the CI. They
could require manual editing to change hardcoded paths to toolchains
when used on different environment.
