On unix, Image Magick is not correctly detected
if the CPPFLAGS and LDFLAGS are not correctly set.
I'm proposing to duplicate the
AC_CHECK_HEADER([magick/api.h],[passed=`expr $passed + 1`],[failed=`expr
$failed + 1`])
line. The first instance, verbatim, for windows. The second,
for unix, after adding the result of `Magick-config --cflags`
to CPPFLAGS (that is restored to the previous value afterward).
I'm not completely happy with this part of the patch
- AC_CHECK_LIB( Magick,GetImageInfo, passed=`expr $passed + 1`,
failed=`expr $failed + 1`, [ $LIB_MAGICK ])
+ AC_CHECK_LIB( c,GetImageInfo, passed=`expr $passed + 1`,
failed=`expr $failed + 1`, [ $LIB_MAGICK ])
The reason of this change is that on some systems
the Magick library is not called libMagick.
For example, on my system I have
libMagickWand and libMagickCore
This is already taken in account by `Magick-config --libs` in
LIB_MAGICK="`Magick-config --ldflags` `Magick-config --libs`"
so we simply have to check that a program using GetImageInfo can be
built with LIB_MAGICK flags. Unfortunately, AC_CHECK_LIB requires a
library name. So, I'm trying to fool the macro using, as library name,
the c standard library. I dont' know there is any macro better suited
for the check we want to perform here.
