[Libguestfs] [PATCH nbdkit 0/13] Port to Windows without using a separate library.
Also available here: https://github.com/rwmjones/nbdkit/tree/2020-windows-mingw-nolib After a lot of work I have made the port to Windows work without using a separate library. Instead, on Windows only, we build an "import library" (library of stubs) which resolves references to nbdkit_* functions in the main program and fixes up the plugin, basically the first technique outlined in this email: https://www.redhat.com/archives/libguestfs/2020-August/msg00268.html Most tests fail, unsurprisingly. The vast majority fail because we lack support for Unix domain sockets. There is some hope that we could add this: https://devblogs.microsoft.com/commandline/af_unix-comes-to-windows/ Although this could fix many tests, it's probably not going to be very useful for actual Windows users. Another large cause of test failures is lack of --run option which might also be fixed with a lot of effort. As before it's entirely possible to develop on, compile and test this series using only the tools provided in Fedora or RHEL. You need a few mingw64-* packages and wine. (Note you don't need to run wine explicitly, there should be a binfmt handler installed which allows you to run nbdkit.exe directly). Apart from having to use ./nbdkit.exe to run the wrapper, it should all work the same way, eg: ./nbdkit.exe -f -v memory 1G ./nbdkit.exe -f -v file disk.img starts a RAM disk or exports a file. This patch series should contain fixes for everything picked up on in previous reviews. Rich.

[Libguestfs] [PATCH nbdkit 01/13] common/replacements: Replace missing functions using LIBOBJS.
Especially on Windows, some common functions are missing. Use the
autoconf LIBOBJS mechanism to replace these functions.
This includes replacement functions for:
Function names Implementation Origin
getdelim, getline general purpose NetBSD under a compatible license
openlog, syslog, Win32 written by me
vsyslog
realpath Win32 written by me
strndup general purpose NetBSD under a compatible license
This should do nothing on existing supported platforms. It is only
intended in preparation for porting nbdkit to Windows.

[Libguestfs] [PATCH nbdkit 08/13] server: Port nbdkit to Windows.
This is a partial port of nbdkit to Windows using native APIs. On
Linux we can use mingw-w64 and Wine to cross-compile and run the
server. There are many missing or partially implemented things in
this port, see TODO for a mostly complete list.

+ mingw-w64 libxml2 (optional, but highly recommended)

+
+Other mingw-w64 libraries may be installed which will add

[Libguestfs] [PATCH nbdkit 09/13] build: On Windows every plugin/filter must link with the import library.
In the previous commit we built an import library on Windows
(server/libnbdkit.a). This contains the stubs which allow plugins to
dynamically link to symbols such as nbdkit_error exported by
nbdkit.exe.
An additional complexity is added by libtool which refuses to believe
that it's possible to add a *.a file when generating a dynamic
library. We must therefore hide the *.a file from libtool by using
-Wl options (ie. passing the library directly through to the linker).

[Libguestfs] [PATCH nbdkit 12/13] wrapper: Port the wrapper to run on Windows.
This also defines SOEXT as the extension of shared objects (ie. "so"
or "dll"), and uses it everywhere. I assumed this must already be
defined by either autoconf or mingw (like OBJEXT) but I cannot find
anything except in glib (G_MODULE_SUFFIX).
Thanks: Zebediah Figura for helping out with exec vs spawn on Windows.

[Libguestfs] [PATCH nbdkit 13/13] tests: Port some tests to Windows.
The vast majority of tests fail currently because Unix domain sockets
have not been implemented. There is some hope we could make them
work, see:
