Re: imagemagick support on W32

[Christoph <cschol2112@googlemail.com>]

I found the linker problem. This is the correct way to configure:

configure.bat --no-cygwin --enable-checking --with-gcc --distfiles 
D:/devel/emacs/libXpm-3.5.8/src/libXpm.dll --cflags 
-IC:/Progra~2/GnuWin32/include --cflags 
-ID:/devel/emacs/libXpm-3.5.8/include --cflags 
-ID:/devel/emacs/libXpm-3.5.8/src --cflags 
-IC:/Progra~2/ImageMagick-6.6.4-Q16/include --ldflags 
-LC:/Progra~2/ImageMagick-6.6.4-Q16 --ldflags -lCORE_RL_magick_ 
--ldflags -lCORE_RL_wand_

i.e.

-LC:/Progra~2/ImageMagick-6.6.4-Q16

not

-LC:/Progra~2/ImageMagick-6.6.4-Q16/lib

Now the only problem is this:

Line 8631 of image.c:

return CHECK_LIB_AVAILABLE (&imagemagick_type, 
init_imagemagick_functions, libraries);

Where is init_imagemagick_functions defined?

For example, init_png_functions is defined in image.c, but 
init_imagemagick_functions is not.

Therefore, the linker complains about a missing reference to 
init_imagemagick_functions when linking with ImageMagick support on Windows.

I added a stub for this function in my code and now it compiles and 
links fine, but it will most likely blow up at runtime.
