This is a pre-approval request.
Thanks for fixing and handling this!

[ Reason ]
xmlrpc-c/1.59.03-10 fix the FTBFS of the reverse dependencies
whom for some other reasons end-up dependening on 'pkgconf'
Ah sorry, should have been more clear and probably give more details
which are not obvious, on the bug report!
This does not seem to currently affect any package in the archive,
but it breaks (external) projects that use pkgconf/pkg-config to get
its build flags.
[ Impact ]
That is not exactly clear to me, but I'm the one _learning_
from all my previous & current interractions with Guillem;
so I trust he's judgement.
*blush* :D
Here's the details I incorrectly obviated from the report. With the
version in trixie right now:
,---
$ xmlrpc-c-config --libs | sed -e 's/^/STDOUT: /'; echo EXIT:$?
Package expat was not found in the pkg-config search path.
Perhaps you should add the directory containing `expat.pc'
to the PKG_CONFIG_PATH environment variable
Package 'expat', required by 'virtual:world', not found
STDOUT: -L/usr/lib/x86_64-linux-gnu -lxmlrpc -lxmlrpc_util -lpthread
EXIT:0
`---
Which is what I think most packages are currently using in Debian. But
the problem is with:
,---
$ pkgconf --libs xmlrpc | sed -e 's/^/STDOUT: /'; echo EXIT:$?
Package expat was not found in the pkg-config search path.
Perhaps you should add the directory containing `expat.pc'
to the PKG_CONFIG_PATH environment variable
Package 'expat', required by 'xmlrpc', not found
EXIT:1
`---
So this does not ignore the errors, and then produces no output, so
library users end up failing to link against the library, where expat
is an implementation detail, that should only be needed when statically linking.
With the fixed libxmlrpc-core-c3-dev package, which pulls in
libexpat1-dev, we should get instead:
,---
$ pkgconf --libs xmlrpc | sed -e 's/^/STDOUT: /'; echo EXIT:$?
STDOUT: -lxmlrpc -lxmlrpc_util
EXIT:0
`---
,--
$ pkgconf --static --libs xmlrpc | sed -e 's/^/STDOUT: /'; echo EXIT:$?
STDOUT: -lxmlrpc -lxmlrpc_util -lexpat -lm
EXIT:0
`---
Thanks,
Guillem
