Hi, To get guile-1.9.14 cross built for mingw, I re-updated gnulib to include socket-related modules (starting with accept here) gnulib-tool --import --dir=. --lib=libgnu --source-base=lib --m4-base=m4 --doc-base=doc --tests-base=tests --aux-dir=build-aux --libtool --macro-prefix=gl --no-vc-files alignof alloca-opt announce-gen autobuild byteswap canonicalize-lgpl duplocale environ extensions flock fpieee full-read full-write func gendocs getaddrinfo git-version-gen gitlog-to-changelog gnu-web-doc-update gnupload havelib iconv_open-utf inet_ntop inet_pton isinf isnan lib-symbol-versions lib-symbol-visibility libunistring locale maintainer-makefile nproc putenv stat-time stdlib strcase strftime striconveh string sys_stat verify version-etc-fsf vsnprintf warnings accept bind close connect getpeername getsockname getsockopt listen malloc malloca recv recv recvfrom send sendto setsockopt shutdown socket sockets and used the attached patches. Without this update you get things like .libs/socket.o:socket.c:(.text+0xc72): undefined reference to `_accept_used_without_requesting_gnulib_module_accept' when building for mingw. The full cross build recipe is in GUB git://github.com/janneke/gub.git in the guile-1.9 branch https://github.com/janneke/gub/blob/guile-1.9/gub/specs/guile.py Of course, when cross building someone should verify that build and host have the same endianess and word size. This means that for cross building on an x86_64 box, we'd probably need to build a 32-bits guile too. Another small gripe, this handy thing in configure.ac m4_esyscmd([build-aux/git-version-gen\ .tarball-version\ 's/^release_\([0-9][0-9]*\)-\([0-9][0-9]*\)-\([0-9][0-9]*\)/v\1.\2\.\3/g']), makes it tricky to patch configure.ac when working from a tarball release, I got $ autoreconf Usage: build-aux/git-version-gen $srcdir/.tarball-version configure.ac:39: error: AC_INIT should be called with package and version arguments /home/janneke/vc/gub/target/tools/root/usr/share/aclocal-1.10/init.m4:26: AM_INIT_AUTOMAKE is expanded from... configure.ac:39: the top level autom4te: /home/janneke/vc/gub/target/tools/root/usr/bin/m4 failed with exit status: 1 esp. because the README talks about ./autogen.sh which does not exist.
