multiple definition of `_zlibVersion'

[Paul J]

Hi, I'm trying get ImageMagick 6.5.0.0 to compile with MinGW/MSYS (1.0.10). I built jpeg, tiff, and png (v1.2.35) libraries first. My configure output is below.

The ImageMagic make outputs...

I found this post...
viewtopic.php?f=3&t=11088
and tried the solution for this, modifying the configure file for PNG as shown below...

/* Override any GCC internal prototype to avoid an error.
Use char because int might match the return type of a GCC
builtin and then its argument prototype would still apply. */
#ifdef __cplusplus
extern "C"
#endif
char zlibVersion ();
int
main ()
{
return zlibVersion ();
;
/* return 0; per viewtopic.php?f=1&t=11419 */
return "1.2.3";
}

but it didn't help. Any ideas?
Thanks in advance..

Paul

We compiled ImageMagick 6.5.1-6 just yesterday without complaint under Ming / MSYS. Not sure while its failing for you.

I was wondering, do you included png (http://www.libpng.org/pub/png/libpng.html, v1.2.35) code? It seems to be having a problem with it.
