Here are the packages.

Overall comments: I see you reverted to bundling the DLLs with the compiler packages (e.g. no separate mingw64-x86_64-libfoo-* tarballs). While it isn't the way I would do it, that's your choice as maintainer (and Yaakov would agree with you, not me).

Many of the setup.hint's specify
requires: mingw64-x86_64-gcc

I *think* that should be
requires: mingw64-x86_64-gcc-core.

You don't actually HAVE a 'mingw64-x86_64-gcc' package, except for the
source-only one. And I'm sure you don't mean to require everybody to
install the source code...


Sorry, I was recycling setup.hint from earlier tries. I will fix this.

OK, and rebuilds fine from source.

Rebuilds fine from source (*), but the binary tarball above is not ok. It has the headers in the following directory: usr/x86_64-w64-mingw32/sys-root/mingw/x86_64-w64-mingw32/include/ instead of usr/x86_64-w64-mingw32/sys-root/mingw/include/

Now, if I *rebuild*, the binary tarball generated has the headers in the
correct spot; I think you just uploaded an old version.


Strange, I'll try a rebuild. The former should be the correct location.

OK, and (mostly) rebuilds fine from source. I had to comment out the Ada parts. Even though I had gcc4-ada-4.3.4 installed, rebuilding your package with Ada enabled failed. However, I've *never* tried to build Ada before, so it may be that I'm missing some pre-requisite.

Or does building gcc-4.5.x Ada require a newer native Ada compiler than
4.3.4?


I installed gcc 4.5.x from experimental for this purpose. The GCC docs say to have a native ada compiler of the same version installed first. GCC 4.5.0 and 4.5.1 should be close enough.



(*) I notice that both the -headers and -runtime cygport included this line as the final command in src_install:

mv ${D}${CROSS_PREFIX}/${CROSS_HOST}/* ${D}${CROSS_PREFIX}

I see the same thing when I tried to use my old mingw*-zlib cygport; I
think the problem is in cygport(1), and your cygport(5) is just working
around the issue.


To sum up, assuming the Ada thing has a reasonable explanation, and the setup.hints are fixed, I think this is GTG.


If you want to hold off and see what Yaakov does about the issue below, and maybe revise your cygport(5)'s based on a new release of cygport(1), that's up to you.



OK, my cygport was mostly from Yaakov's examples.



========== POSSIBLE CYGPORT(1) BUG ============= Yaakov?

the config.status for includedir has this:
S["includedir"]="${prefix}/include"
but other dirs are explicit:
S["bindir"]="/usr/x86_64-w64-mingw32/sys-root/mingw/bin"

Looking at the configure command (from config.status):

'/usr/src/mingw64/headers/mingw64-x86_64-headers-svn3433-1/src/mingw-w64-headers/configure'

'--srcdir=/usr/src/mingw64/headers/mingw64-x86_64-headers-svn3433-1/src/mingw-w64-headers'
'--prefix=/usr/x86_64-w64-mingw32/sys-root/mingw'
'--exec-prefix=/usr/x86_64-w64-mingw32/sys-root/mingw'
'--bindir=/usr/x86_64-w64-mingw32/sys-root/mingw/bin'
'--sbindir=/usr/x86_64-w64-mingw32/sys-root/mingw/sbin'
'--libexecdir=/usr/x86_64-w64-mingw32/sys-root/mingw/lib'
'--datadir=/usr/x86_64-w64-mingw32/sys-root/mingw/share'
'--localstatedir=/usr/x86_64-w64-mingw32/sys-root/mingw/var'
'--sysconfdir=/usr/x86_64-w64-mingw32/sys-root/mingw/etc'
'--datarootdir=/usr/x86_64-w64-mingw32/sys-root/mingw/share'
'--docdir=/usr/x86_64-w64-mingw32/sys-root/mingw/share/doc/mingw64-x86_64-headers'
'-C' '--build=i686-pc-cygwin' '--host=x86_64-w64-mingw32'
'--target=x86_64-w64-mingw32' '--enable-sdk=all'
'build_alias=i686-pc-cygwin' 'host_alias=x86_64-w64-mingw32'
'target_alias=x86_64-w64-mingw32' $ac_configure_extra_args --no-create
--no-recursion

I see that --includedir is missing. I think that is an oversight in
autotools.cygclass, and --includedir should be one of the elements
specified in confargs:

confargs="--prefix=${prefix} --exec-prefix=${prefix}
--bindir=${prefix}/bin \
--sbindir=${prefix}/sbin --libexecdir=${prefix}/lib \
--datadir=${prefix}/share --localstatedir=${prefix%/usr}/var \
--sysconfdir=${prefix%/usr}/etc"

I'm not real sure about the ${prefix%/...} manipulation, either,
especially for cross. (The effect of this manipulation for a cross for
$host=mingw is not apparent, since $prefix doesn't actually end in /usr
in that case). But...the current code seems to be incorrect, IMO.


As an aside, I happened to notice there is a bug in cyginstall() when USE_DESTDIR=0, inherit cross, and $host is mingw: localstatedir (/var) and sysconfdir (/etc) aren't handled correctly. But that has little to do with JonY's mingw-w64 ITP.
