There's no need for the cross prefix here. After you've run ./configure with --cross-prefix, argument, you'll see the following in build/config-meson.cross file: [binaries] .... widl = ['x86_64-w64-mingw32-widl'] windres = ['x86_64-w64-mingw32-windres'] windmc = ['x86_64-w64-mingw32-windmc'] And these are the actual values meson's find_program() is going to be looking for. So it doesn't seem like there's anything broken here, it's a matter of build requirements. > > Regards > Stefan

Here's what's happening: Makefile:72 > # force a rerun of configure if config-host.mak is too old or corrupted > ifeq ($(MESON),) > .PHONY: config-host.mak > x := $(shell rm -rf meson-private meson-info meson-logs) > endif Makefile:92 > # 1. ensure config-host.mak is up-to-date > config-host.mak: $(SRC_PATH)/configure $(SRC_PATH)/scripts/meson-buildoptions.sh $(SRC_PATH)/VERSION > @echo config-host.mak is out-of-date, running configure > @if test -f meson-private/coredata.dat; then \ > ./config.status --skip-meson; \ > else \ > ./config.status && touch build.ninja.stamp; \ > fi configure:2529 > if test "$skip_meson" = no; then > ... > echo "widl = [$(meson_quote $widl)]" >> $cross > echo "windres = [$(meson_quote $windres)]" >> $cross > echo "windmc = [$(meson_quote $windmc)]" >> $cross Now if you checkout a revision which doesn't have this patch, perform a build, then checkout to a revision which has this patch and try to perform a build again, ./configure will be called with --skip-meson and config-meson.cross won't be regenerated. I'm not sure how we could detect a necessity to regenerate config-meson.cross in this case. Your suggestions are welcome, if any.

This commit allows QGA to write to Windows event log using Win32 API's ReportEvent() [1], much like syslog() under *nix guests. In order to generate log message definitions we use a very basic message text file [2], so that every QGA's message gets ID 1. The tools "windmc" and "windres" respectively are used to generate ".rc" file and COFF object file, and then the COFF file is linked into qemu-ga.exe.
