The easiest way is to use the gpg4win installer (the tar.bz2 file) which
makes sure that everthing is in place.   If you want to manually build
it, I suggest to create a directory


or alternativley any other directory and set w32root=directory.  Then
you can just use

 ./ --build-w32 && make install

for all GnuPG related packages (those with that script).  For the other
packages you need to pass appropriate options to ./configure.  Start
with libgpg-error, libgcrypt, w32pth, libassuan, libksba.

That's okay.

libassuan requires libws2_32 as well.  Compare your ld command to mine:

../gl/libgnu.a ../common/libgpgrl.a -lz -lws2_32 -L/home/wk/w32root/lib
-lgcrypt -lgpg-error -L/home/wk/w32root/lib -lassuan -lws2_32
-L/home/wk/w32root/lib -lgpg-error

Here you see -lws2_w32 after -lassuan.  This is because my
libassuan-config says this.

  $ ~/w32root/bin/libassuan-config --libs
  -L/home/wk/w32root/lib -lassuan -lws2_32

My conclusion is that you do did use "./ --build-w32" for
libassuan or forgot to run "make install". The GnuPG build command is:

    ./configure --enable-maintainer-mode --prefix=${w32root}  \
             --host=${host} --build=${build} \
             --with-gpg-error-prefix=${w32root} \
	     --with-ksba-prefix=${w32root} \
	     --with-libgcrypt-prefix=${w32root} \
	     --with-libassuan-prefix=${w32root} \
	     --with-zlib=${w32root} \
	     --with-regex=${w32root} \
             --with-pth-prefix=${w32root} \
             --with-adns=${w32root} \
             --without-included-gettext "$@"

which uses "--with-libassuan-prefix=${w32root}" and thus takes 
libassuan-config from ~/w32root/bin/.



Die Gedanken sind frei.  Auschnahme regelt ein Bundeschgesetz.
