That's a little odd, and I don't think that's exactly what was meant by
the documentation http://cygwin.com/setup.html#package_contents.
I don't think this is a showstopper for this release, but ordinarily
configuration files belong in the top-level /etc directory. However,
once installed there, a name like "backend.cfg" is poorly chosen, since
it doesn't really indicate what package it belongs to, and thus might
conflict with some other package.
/usr/share/<pkg>/ is usually used for other, more extensive data files
and support -- e.g. that's probably where your star catalog files
(indexes?) ought to go.
Furthermore, if backend.cfg is user-editable, then you would probably
want to install it into
and include a postinstall/preremove scripts here:
whose job is to (a) copy the "default" version into /etc on install, IF
no such file already exists, and (b) remove the /etc/backend.cfg file on
uninstall, if and only if it is identical to the /etc/defaults/ one. See
/etc/postinstall/tcp_wrappers.sh [or .done]
for and example. FYI, cygport will handle creating these scripts for
you (almost) automatically, via a single command:
All this complexity is so that user-modified configuration settings
don't get clobbered by package updates, but non-modified files will get
However, what is probably a showstopper are various lines like this in

IOW, cygwin python's distutils is _doing the right thing_ -- creating
the plugin with the name spherematch_c.dll -- but the Makefile in
astrometry.net thinks the plugin will always be named spherematch_c.so
and reports an error when it tries to install the latter file.
Also, when I did 'make install ...' my lib/astrometry/bin directory was
I can't help but think this will cause problems for your users...
Now, this bit is interesting:
- mkdir -p $(INSTALL_DIR)/python/astrometry/libkd
+ mkdir -p $(INSTALL_DIR)/share/astrometry/python/astrometry/libkd
Normally, python extensions go under the "real" python dir:
But...this whole build system doesn't really support that; it hardcodes
the destination path and then adds that path to sys.path via the
"application" .py files; when it really should use some mechanism to
find the entry in $python's sys.path list which contains "site-packages".
So...accepting that, the python stuff should ALSO go under /lib rather
than /share, because (a) the .pyc files are platform specific, and (b)
the .dll's which ought to go there are also platform specific.
....so, not GTG. Also, you missed Corinna's statement: "If the binaries
are using it (the libbackend library), they should also be linked
against [the DLL], rather than being linked statically."
Your build still links against libbackend.a, rather than cygbackend.dll.
I'm trying to massage your -src package to DTRT. Stay tuned.
