Glad that you asked -- revisiting my notes from Feb27 this year...

talloc compiles far enough to get to work with notmuch in cygwin

Here are steps to get notmuch working in cygwin, just updated

--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--

* notmuch-cygwin

-- latest notmuch HEAD (0.24.x may be too old (zlib configure checks))

-- packages:
        gcc-g++
        pkg-config
        zlib-devel

        libxapian-devel
        libgmime2.6-devel
        libiconv-devel

        python-sphinx

-- talloc to be compiled -- see below

--- install package curl (or wget...) some "fw" rules may prohibit either...

   : in notmuch source directory
   curl -k -O https://download.samba.org/pub/talloc/talloc-2.1.8.tar.gz
   tar xf talloc-2.1.8.tar.gz
   cd talloc-2.1.8/
   ./configure ;: takes some time -- quite a few emulated forks...
   : 'configure' finished successfully (5m23.539s)
   make ;: (warns about -fPIC, ignore). fails...
   ln -s cygtalloc-2.dll bin/default/talloc.dll
   ln -s cygtalloc-2.dll bin/default/cygtalloc.dll
   make ;: 'build' finished successfully (0.992s)

   cd ..
   : now back in notmuch dir -- disable talloc check
   sed -n '/exists talloc/ s/ / : /p' configure
   sed -i '/exists talloc/ s/ / : /' configure :; yau, GNU sed ,/
   echo '#define asprintf(pp, ...) talloc_asprintf(NULL, __VA_ARGS__)' >> lib/notmuch-private.h
   CPATH=$PWD/talloc-2.1.8 LIBRARY_PATH=$PWD/talloc-2.1.8/bin/default ./configure
   sed -i '/TALLOC_LDFLAGS/ s/$/ -ltalloc/' Makefile.config
   CPATH=$PWD/talloc-2.1.8 LIBRARY_PATH=$PWD/talloc-2.1.8/bin/default make
   : linking notmuch-shared fails... but "non"shared works, as usual
   : cygwin (windows?) uses PATH to find .dll's too
   PATH=./talloc-2.1.8/bin/default:$PATH ./notmuch.exe --version
   : notmuch 0.24.1+84~g6ac3d8c
   PATH=./talloc-2.1.8/bin/default:$PWD:$PATH emacs -L $PWD/emacs -f notmuch
