Description Pierre Amadio 2011-02-23 10:21:38 UTC

This is the same as fedora bz#641639
With graphviz-2.26.0-4.el6, the php gv.so module does not load and generate the following warning:

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/gv.so' - /usr/lib64/php/modules/gv.so: undefined symbol: zend_error_noreturn in Unknown on line 0

This seems due to the fact that the swig library used to build the php module is still using zend_error_noreturn function (see bz#679713)

Rebuilding the graphviz with a modified swig (with change zend_error_noreturn to zend_error available in bz#679713) fixed the problem.
