Cross compilation failed

Hi all. I want to make a Win32 port of GnuPG 2.0.10 from my sid with
the help of mingw32.
$ dpkg -l "mingw32*"
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-

ii mingw32-runtime 3.13-1 Minimalist GNU win32
(cross) runtime

I downloaded the following libraries for building GnuPG:
libgcrypt-1.4.4.tar.bz2
w32pth-2.0.2.tar.bz2
libgpg-error-1.7.tar.bz2
zlib-1.2.3.tar.gz
gettext-0.17.tar.gz
libiconv-1.12.tar.gz
readline-5.0-1-bin.zip
readline-5.0-1-lib.zip
libassuan-1.0.5
libksba-1.0.5.tar.bz2
libassuan-1.0.5.tar.bz2

When cross compiling libassuan, I got the following warnings:
configure: WARNING:
***
*** Data structure for sending ancillary data missing.
*** Descriptor passing won't work.
***
***
*** No implementation of fopencookie or funopen available.
*** The assuan_get_data_fp feature won't work.
***
But it succeeded in creating the library itself.

However when it comes to linking GnuPG, something went wrong:

I think there might be something wrong with my compilation of
libassuan. But I am not sure what caused it. Could anybody tell me how
to fix it?

Thank you a lot!

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

$HOME/w32root

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

./autogen.sh --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 "./autogen.sh --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/.

Shalom-Salam,

Werner
