Package: pkg-config
Version: 0.29.2-1
Severity: normal
Tags: patch
Hello,
With newer dpkg-architecture (I'm using 1.19.7), when I cross build
for i686-w64-mingw32, the command i686-w64-mingw32-pkg-config (linked
to pkg-config-crosswrapper) fails with the message:
Please install dpkg-dev to use pkg-config when cross-building
... even if dpkg-dev is installed.
This is because the command invocation in pkg-config-crosswrapper
dpkg-architecture -ti686-w64-mingw32 -qDEB_HOST_MULTIARCH
fails with the message:
dpkg-architecture: error: unknown GNU system type i686-w64-mingw32, you must
specify Debian architecture, too
with the exit code of 255 (as of version 1.19.7).
# It is related to the change of dpkg and this dpkg bug:
# https://bugs.debian.org/606825
#
# When I modify /usr/share/dpkg/ostable and
# /usr/share/dpkg/tupletable, I can let i686-w64-mingw32-pkg-config
# work correctly.
If we can depend on the behavior of shell having the exit code of 127 when
it can't find the command, I think that we can do like this:

Could you please consider an improvement like this?
Well, let me explain my situation adding some more information.
I encounter this bug when I cross build GnuPG for i686-w64-mingw32 on
Debian host. Note that Debian's GnuPG package build process includes
building gpgv for Windows (IIUC, so that it can be used for
win32-loader).
Even if I have dpkg-dev installed, when the GnuPG's configure script
invokes pkg-config, pkg-config fails like:
=====================
...
checking for cc for build... cc
checking for i686-w64-mingw32-pkg-config... /usr/bin/i686-w64-mingw32-pkg-config
checking pkg-config is at least version 0.9.0... Please install dpkg-dev to use
pkg-config when cross-building
no
