Without this export, the host variant of g-ir-scanner will call the host
gcc for linking.
For autotools packages, this is not an issue as they use
Makefile.introspection, which will export the cross-cc, however for meson,
this is not the case, and linking errors occur when meson packages generate
.gir and .typelib files.

HHhmmm. I remember that I said I wanted the wrapper to still be
rrrelocatable. But it is in staging (sysroot) while the compiler is in
host dir, so you added that many .././/.. needed to got from there to
there.
But look at the line below: we already have HOST_DIR:
> ${HOST_DIR}/bin/g-ir-scanner \
^^^^^^^^^^^
So, just:
export CC="${HOSTTT_DIR}/bin/@BASENAME_TARGET_CC@"
Or did we miss something?

That's what I had originally and you said to change it to this!
Make up your mind! These patches take 2 - 3 weeks each to be reviewed
and it is fairly annoying when a request for a change comes through, I make that
change quickly, the changes sit for several weeks, and then a new
request to revert
the change that was originally requested comes in.
I will remake the patch with
HOST_DIR again.

That's not exactly what you did, which was:
export CC=@TARGET_CC@
and:
$(SED) "s%@TARGET_CC@%$(TARGET_CC)%g" $(STAGING_DIR)/usr/bin/g-ir-scanner
So, even if it would use the same path, it is not semantically
equivalent.

Sorry, but as you know well, this is a volunteer effort, and there is
always so much time available, and so many patches pending.
I agree that it can be frustrating, yes. I've been there too. We've all
been there...
But please, be sure that your work is very welcome. It's just that the
goi is so baly borked by design that it makes the topic so complex.
And when applying something, I like to at least have the impression that
I do understand the problkem and that the fix, how ugly it is, is indeed
the only solution.

Currently, meson hard codes the paths of these binaries which results in
cross-compiled environments to run the host versions of these tools.
However, GObject-introspection provides the appropriate paths to these
utilities via pkg-config
find_program is needed in the case g-i is built as a subproject. If
g-ir-scanner or g-ir-compiler are in the build or source directory use those.
If they aren't found in the source directory, use the results from pkg-config.

This is backporting two commits, so should be two patches.

I guess? The second patch fixes the first one. Is there any reason why
it would have to be two patches other
than precednence?

What's LDPATH? Did you mean LDFLAGS? Or LD_RUN_PATH? Or soemthing else?
Still, this is not clear what the problem is, and why we need
LD_LIBRART_PATH. We already discussed this on IRC, and you said upstream
said to use it, but I am still not convinced, because this is really
ugly.
Also, this is not just g-ir-scanner that has the problem Is we were to
just export LD_LIBRARY_PATH in our wrapper, that would stil cause build
failures:
1 #!/usr/bin/env bash
2
3 export GI_SCANNER_DISABLE_CACHE=1
4 export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}${HOST_DIR}/lib" # Not enough!
5 ${HOST_DIR}/bin/g-ir-scanner \
6 --lib-dirs-envvar=GIR_EXTRA_LIBS_PATH \
7 --use-binary-wrapper=$(dirname $0)/g-ir-scanner-qemuwrapper \
8 --use-ldd-wrapper=$(dirname $0)/g-ir-scanner-lddwrapper \
9 --add-include-path=$(dirname $0)/../share/gir-1.0 "$@"
> order to ensure that g-ir-scanner does not use the host library path.
Did you mean:
... that g-ir-scanner does not use the system-install libglib2.
There is indeed a problem, but I still don't understand it, and even if
setting LD_LIBRARY_PATH does indeed solve the issue, I'm still not happy
about that... :-(
Yeah, we've already concluded that anything goi related would have to be
ugly by design... Still, I'm not happy... :-(
Maybe if the commit log were to at least point at the discussion with
upstream (on their issue tracker?), that could make the pill easier to
swallow... :-/

Yann E. MORIN.

I meant LDFLAGS. Sorry about that.

It's specifically needed during the build process because during the
build process
host-goi builds and calls g-ir-scanner to build .gir files. I don't
like it either, but it
works and on IRC a maintainer told me that it needs to be exported and that is
the correct solution.

The host computer or system-installed libglib2.
