undefined reference to `MagickSetImageEndian' in 1.0.9

[BilboUK]

MagickWandForPHP 1.0.9 will not compile against the currently released versions of ImageMagick.

I don't know which version of ImageMagick the devs compiled it against but I tried ImageMagick-6.7.5-7 as well as the allegedly "approved" version 6.3.5-9 as specified in INSTALL (which is wrong since it's < the minimum version required by the compiler!) and version 6.3.8-11 (as specified in ./configure script).

None of these worked since the method MagickSetImageEndian() doesn't appear to exist in those versions of ImageMagick.

I reverted to MagickWandForPHP 1.0.8 and it compiles (& works) just fine with 6.7.5-7 (although the compiler reports a lot of deprecated methods and 'incompatible pointer type' warnings).

(p.s. sorry for also posting in MagickWand forum - I post it here in case any of the MagickWandForPHP devs read this forum).

Are there no developers reading this forum? There are multiple reports of this problem all over this forum, other forums on this site, and elsewhere.

Here is the bug report the MacPorts project received about this problem, but it's not our problem to fix:

https://trac.macports.org/ticket/34089

Please fix this problem and release a new version of MagickWand for PHP containing the fix. Thank you.

We'll have a patch for the problem you reported in the ImageMagick 6.7.7-1 release, available within a few days. Thanks.

Thank you. I updated ImageMagick to 6.7.7-2 but the problem remains, even after rebuilding php-magickwand 1.0.9.

Check wand/magick-image.c and look for MagickSetImageEndian(). It should be there. If so, perhaps MagickWand for PHP is not linking against that version of the ImageMagick MagickWand library.

I got a different error:

undefined reference to `MagickGetImageEndian'

It is Get not Set!

[magick]

We'll have a patch for the problem you reported in the ImageMagick 6.7.7-6 release, available within a few days. Thanks

Yes it is, as is MagickGetImageEndian().

If so, perhaps MagickWand for PHP is not linking against that version of the ImageMagick MagickWand library.

There is no other version installed.

The problem remains using ImageMagick 6.7.8-5. When starting php when php-magickwand 1.0.9 is installed, a warning is printed:

for this issue, you should add the code in the file magickwand.c (which is in the package "MagickWandForPHP 1.0.9")

Code: Select all

/* {{{ proto bool MagickSetImageEndian( MagickWand magick_wand, int endian_type ) 
	*/ 
PHP_FUNCTION( magicksetimageendian ) 
{ 
	MW_PRINT_DEBUG_INFO 

	MW_GET_MAGICKWAND_SET_ENUM_RET_BOOL( EndianType, MagickSetImageEndian ); 
} 
/* }}} */

Thanks for the tip zhaoley.
It seems a shame that no-one is maintaining this extension any more. I find it very useful.

We'll get your patch into the next point release of MagickWand. It should be available within just a few days. Thanks.
