build broken with zlib 1.2.6

[jue]

Build of imagemagick is broken with latest version of zlib, 1.2.6. Guess it's because of this change in zlib.h:

Code: Select all

-typedef voidp gzFile;       /* opaque gzip file descriptor */
+typedef struct gzFile_s *gzFile;    /* semi-opaque gzip file descriptor */

I get the following errors:

Download ImageMagick 6.7.5-0, the current version. It compiles against Zlib 1.2.6.

Sorry, but it was against 6.7.5, as you can see in my build log, but looks like you've updated the sources without
changing the version. Anyway it works now, thanks for your quick response.
