+Subject: [PATCH 1/2] Optionally use native generators
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+fprint-list-udev-hwdb and fprint-list-udev-rules are run
+during the build to generate autosuspend.hwdb and 70-*.rules,
+respectively.
+
+Since they are not marked as "native: true", a cross-compiled
+version is not possible.
+
+Since these binaries are linked with the libfprint_drivers target,
+marking them as native binaries would also need libfprint_drivers
+to be duplicated as a native version and possibly other library
+targets, too.
+
+Instead, make it the responsibility of the cross-compiler
+framework to build the native variant separately and allow
+the external binaries to be passed in.

Meson is specifically configured in yocto to user qemu usermode as the
wrapper to run cross binaries, so can libfprint build configuration be
tweaked to use that? This would avoid all the nasty -native extensions
and modifications.

Wasn't the mariadb change I made about 2 years ago
to use cmake's CROSSCOMPILING_EMULATOR that saved
building the whole mariadb-native just for one small binary
reverted recently because qemu doesn't emulate certain
parts of the instruction set and caused crashes?

The same principle applies to meson running binaries via qemu, too.

The executable is built, it is there, and it's using the target system's
runtime linker path.

Obviously, meson doesn't run it through the exe_wrapper.

How do libfprint's meson rules for producing the executable and then
running it look like?

Any meson based recipe has a similar entry in ${WORKDIR}/meson.cross:

exe_wrapper = '/srv/storage/alex/yocto/build-64-alt/tmp/work/core2-64-poky-linux/glib-2.0/1_2.74.6-r0/meson-qemuwrapper'

And the use of the exe_wrapper is documented here:
https://mesonbuild.com/Cross-compilation.html

Meson is specifically configured in yocto to user qemu usermode as the
wrapper to run cross binaries, so can libfprint build configuration be
tweaked to use that? This would avoid all the nasty -native extensions
and modifications.

How would I do that? This is the error if I not use the
externally built executables:

The executable is built, it is there, and it's using the target system's
runtime linker path.

Obviously, meson doesn't run it through the exe_wrapper.

It is possible that meson doesn't support running executables
via exe_wrapper whose output is captured in a file?

Maybe rewriting the generators to write their output directly
instead of on stdout will make libfprint more cross compiler
friendly.

Maybe you can raise the concern with upstream and see what they say?
How, in their opinion, should their component be cross-compiled? Can
the need to run target executables be eliminated from the build in
some other way we're not seeing?

How do libfprint's meson rules for producing the executable and then
running it look like?

Here are the two generators:
https://gitlab.freedesktop.org/libfprint/libfprint/-/blob/master/libfprint/meson.build#L310
https://gitlab.freedesktop.org/libfprint/libfprint/-/blob/master/libfprint/meson.build#L325

Any meson based recipe has a similar entry in ${WORKDIR}/meson.cross:

exe_wrapper = '/srv/storage/alex/yocto/build-64-alt/tmp/work/core2-64-poky-linux/glib-2.0/1_2.74.6-r0/meson-qemuwrapper'

Yes, and it's created for libfprint, it's just not used.
Otherwise running the executable would have succeeded.

And the use of the exe_wrapper is documented here:
https://mesonbuild.com/Cross-compilation.html

Meson is specifically configured in yocto to user qemu usermode as the
wrapper to run cross binaries, so can libfprint build configuration be
tweaked to use that? This would avoid all the nasty -native extensions
and modifications.

How would I do that? This is the error if I not use the
externally built executables:

The executable is built, it is there, and it's using the target system's
runtime linker path.

Obviously, meson doesn't run it through the exe_wrapper.

+fprint-list-udev-hwdb and fprint-list-udev-rules are run
+during the build to generate autosuspend.hwdb and 70-*.rules,
+respectively.
+
+Since they are not marked as "native: true", a cross-compiled
+version is not possible.
+
+Since these binaries are linked with the libfprint_drivers target,
+marking them as native binaries would also need libfprint_drivers
+to be duplicated as a native version and possibly other library
+targets, too.
+
+Instead, make it the responsibility of the cross-compiler
+framework to build the native variant separately and allow
+the external binaries to be passed in.

Right. Welcome to:
https://github.com/mesonbuild/meson/issues/11029

I'm not sure what rules in meson do use the exe_wrapper setting, if
you can investigate that and see if one of them can be used in this
case, would be great. Or those two generators can be patched to prefix
the wrapper.

It needs to address native deps on udev-native I am seeing

This is a problem with using two different mailing lists
and separate layers. Interconnected changes are often
overlooked without taking the changed in the other layer.

This particular problem is addressed by the systemd change
with BBCLASSEXTEND = "native" and other tweaks which
was sent to the openembedded-core ML and is being debated there.

FWIW, this meson bug prevents libfprint to use the exe_wrapper,
which would make the systemd-native recipe unnecessary:

+Subject: [PATCH 1/2] Optionally use native generators
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+fprint-list-udev-hwdb and fprint-list-udev-rules are run
+during the build to generate autosuspend.hwdb and 70-*.rules,
+respectively.
+
+Since they are not marked as "native: true", a cross-compiled
+version is not possible.
+
+Since these binaries are linked with the libfprint_drivers target,
+marking them as native binaries would also need libfprint_drivers
+to be duplicated as a native version and possibly other library
+targets, too.
+
+Instead, make it the responsibility of the cross-compiler
+framework to build the native variant separately and allow
+the external binaries to be passed in.
+
+Upstream-Status: Submitted
