Hi Nikos.
Thanks to your help, I'm getting closer ...

Is your environment set correctly? I have a text file with this in it
(~/bin/mxe-env):

PKG_CONFIG_PATH_i686_w64_mingw32_static="/home/realnc/opt/mxe/usr/i686-w64-mingw32.static/lib/pkgconfig"
I didn't set the PATH before, this definitely helps!
I'm not quite sure if the second line has any effect, but I used it
anyway (changing i686 to x86_64).
Now I get a bit further, but then I get the old warning again (and
then a bunch of linker errors):
*** Warning: This system can not link to static lib archive
[...]/usr/x86_64-w64-mingw32.static/lib/libvorbis.la.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have.
These were the exact steps I did:
# install the required Debian packages
TARGET=x86_64-w64-mingw32.static
git clone https://github.com/mxe/mxe.git
cd mxe/
make libsndfile -j8 JOBS=8 MXE_TARGETS=$TARGET
cd ..
export PATH=$(pwd)"/mxe/usr/bin:$PATH"
export
PKG_CONFIG_PATH_i686_w64_mingw32_static=$(pwd)"/mxe/usr/i686-w64-mingw32.static/lib/pkgconfig"
export
PKG_CONFIG_PATH_x86_64_w64_mingw32_static=$(pwd)"/mxe/usr/x86_64-w64-mingw32.static/lib/pkgconfig"
tar xvzf mxe/pkg/libsndfile-1.0.25.tar.gz
cd libsndfile-1.0.25/
patch -p1 < ../mxe/src/libsndfile-1-fixes.patch
./configure --host=$TARGET --enable-shared --disable-static
--disable-sqlite --enable-external-libs --disable-octave
--disable-alsa LIBS="$($TARGET-pkg-config --libs vorbis ogg)"
make -j8
Did I make a mistake somewhere?
I also tried your suggestion with checking out 0b5be38d, but this led
to the exact same errors.
What else could I try?
cheers,
Matthias
Before using MXE, I do:
. ~/bin/mxe-env
(Note the dot at the start of the command.)
You must NOT set anything else in there.

Hi Nikos.
Thanks a lot, this looks promising!
Everything works fine including "./configure", but I get an error during
"make":

... and many similar errors.
What did I do wrong?
As far as I can tell, the ./configure output looks OK:

This makes a lot of sense in general, but I have a specific case where
I would like to mix static and shared libraries.
I would like to create a DLL for libsndfile, which should statically
include all dependencies (libFLAC, libogg, libvorbis, ...).
Build against a static MXE, but outside of MXE. That's how I create my
self-containted :-)
That means, build everything libsndfile needs in MXE. Statically. But
*don't* build libsndfile itself. Then, build it outside of MXE with
something like the below. It also applies the MXE-specific patch and
rebuilds the configure script for that patch to take effect.
(I assume here that you installed MXE in ~/opt/mxe; adjust the path below
according to your MXE directory.)
cd /tmp
tar xf libsndfile-1.0.25.tar.gz
cd libsndfile-1.0.25
patch -p1 < ~/opt/mxe/src/libsndfile-1-fixes.patch
autoreconf -fi -IM4
./configure --host=i686-w64-mingw32.static --enable-shared
--disable-static --disable-sqlite --disable-octave --disable-alsa
make -j4
This will produce a dll somewhere. Find it with:
find . -iname "*.dll"
That dll should contain everything it needs to run on its own.
The above assumes you're on latest git master of MXE. For the old
"stable"
MXE, you need to adjust the --host accordingly.
Note though: this method can be problematic with C++ exception handling,
since each DLL you produce contains a static copy of libgcc. If you have
several DLLs that are built that way, then each one contains its own
libgcc.
The result of that is that exceptions might not propagate correctly. I
think
this only applies when the DLL is used by an *.exe or another dll that is
written in C++, but I'm not sure.
