Hi all,
I am maintaining a toolchain [1] for cross-compiling GTK+
application for windows on archlinux. I'd like to upstream a
couple of patches, if possible.
The first one (implib.patch) creates an import library on the
mingw target. Credits go to the MSYS2 project: the patch is
theirs. I can't comment on this one as I don't even know what an
import library is... I just know I needed liblua.dll.a later on
the chain and this patch provided it.
The second one instead (strip.patch) is mine. In src/Makefile
there is this line:
"AR=$(CC) -shared -Wl,--out-implib,liblua.dll.a -o" "RANLIB=strip --strip-unneeded" \
that fails when cross-compiling because the native `strip` command
does not work on host code.
Alternatively, if this is a dummy definition (as it seems), the
actual command can be substituted with `touch`, `true` or similar
inoffensive commands.

Ciao.
