Developers often run QEMU without installing. The bundle mechanism
allows to look up files which should be present in installation even in
such a situation.
It is a general mechanism and can find any files located relative
to the installation tree. The build tree must have a new directory,
qemu-bundle, to represent what files the installation tree would
have for reference by the executables.
Note that this abandons compatibility with Windows older than 8 to use
PathCchSkipRoot(). The extended support for the prior version, 7 ended
more than 2 years ago, and it is unlikely that anyone would like to run
the latest QEMU on such an old system.
Thanks, merged.
However there were a couple issues:
- the bashism in patch 4, replaced by
+meson_option_build_array() {
+ printf '['
+ (if test "$targetos" == windows; then
+ IFS=\;
+ else
+ IFS=:
+ fi
+ for e in $1; do
+ e=${e/'\'/'\\'}
+ e=${e/\"/'\"'}
+ printf '"""%s""",' "$e"
+ done)
+ printf ']\n'
+}
+
- oss-fuzz didn't work, it has a syntax error and also can be simplified
to use qemu-bundle as well, like
-# Copy over the datadir
-cp -r ../pc-bios/ "$DEST_DIR/pc-bios"
+# Prepare a preinstalled tree
+make install DESTDIR=$DEST_DIR/qemu-bundle

v10:
* Update destdir_join() in scripts/symlink-install-tree.py with the
latest implementation from Meson:
https://github.com/mesonbuild/meson/pull/10531
v9:
* Update _WIN32_WINNT in include/qemu/osdep.h (Thomas Huth)
v8:
* Pass absolute paths to get_relocated_path() (Paolo Bonzini)
* Use meson introspection (Paolo Bonzini)
* Drop "qga: Relocate a path emitted in the help text" as it is no longer
relevant for the bundle mechanism.
v7: Properly fix --firmwarepath (Daniel P. Berrangé)
v6: Reuse get_relocated_path() in find_bundle() (Paolo Bonzini)
v5:
* Prefer qemu-bundle if it exists. (Daniel P. Berrangé)
* Check install_blobs option before installing BIOSes (Paolo Bonzini)
* Add common code to set up qemu-bundle to the top level meson.build
(Paolo Bonzini)
v4:
* Add Daniel P. Berrangé to CC. Hopefully this helps merging his patch:
https://mail.gnu.org/archive/html/qemu-devel/2022-06/msg02276.html
* Rebased to the latest QEMU.
v3:
* Note that the bundle mechanism is for any files located relative to the
installation tree including but not limited to datadir. (Peter Maydell)
* Fix "bridge" typo (Philippe Mathieu-Daudé)
v2: Rebased to the latest QEMU.
