[Qemu-devel] [PULL for-2.9 2/2] qga: Make qemu-ga compile statically for Windows

[Michael Roth <mdroth@linux.vnet.ibm.com>]

From: Sameeh Jubran <sameeh@daynix.com>

Attempting to compile qemu-ga statically as follows for Windows causes
the following error:

Compilation:
    ./configure --disable-docs --target-list=x86_64-softmmu \
    --cross-prefix=x86_64-w64-mingw32- --static \
    --enable-guest-agent-msi --with-vss-sdk=/path/to/VSSSDK72

    make -j8 qemu-ga

Error:
    path/to/qemu/stubs/error-printf.c:7: undefined reference to `__imp_g_test_config_vars'
    collect2: error: ld returned 1 exit status
    Makefile:444: recipe for target 'qemu-ga.exe' failed
    make: *** [qemu-ga.exe] Error 1

This is caused by a bug in the pkg-config file for glib as it doesn't define
GLIB_STATIC_COMPILATION for pkg-config --static.
