I try to compile Xastir on Cygwin using GraphicMagick. I uninstalled
ImageMagick.
I get the following error:
map_geo.c: In function `draw_geo_image_map':
map_geo.c:1907: error: too few arguments to function `GetNumberColors'
map_geo.c:1914: warning: implicit declaration of function
`CompressColormap'
map_geo.c:2117: error: too few arguments to function `GetNumberColors'
map_geo.c:2117: warning: int format, long unsigned int arg (arg 3)
map_geo.c:2125: error: too few arguments to function `IsGrayImage'
map_geo.c:2126: error: too few arguments to function `IsMonochromeImage'
make[3]: *** [map_geo.o] Error 1
GraphicMagicks's color.h header says "GetNumberColors" needs 3 arguments:
extern MagickExport unsigned long
GetNumberColors(const Image *,FILE *,ExceptionInfo *);
The code im map_geo.c looks like this:
#if (MagickLibVersion < 0x0540)
if (visual_type == NOT_TRUE_NOR_DIRECT && GetNumberColors(image,
NULL) > 128) {
#else // MagickLib >= 540
if (visual_type == NOT_TRUE_NOR_DIRECT && GetNumberColors(image,
NULL, &exception) > 128) {
#endif // MagickLib Version
It looks like this 0x0540 is an *ImageMagick* version nummber.
GraphicMagick has in version.h:
#define MagickLibVersion 0x000008
Which causes the wrong call for GetNumberColors with only 2 arguments.
The easiest solution is to just drop support for ImageMagick < 0x0540...
Kind regards,
Henk.
