Not enough information was provided for us to be able

If you can provide more information, feel free to add it
to this bug and change the status back to "Open".

Thank you for your interest in PHP.


1. Does this also segfault when you load it via an ini file?
2. This appears to be having issues when attempting to load the glade php-gtk extension, is that in an ini file?  Or did you compile it statically into php-gtk?
3. the PECL cairo extension IS a required dependency of php-gtk - did you load that before you attempted to load php-gtk?  PHP should be angry if you don't do that instead of segfaulting - but just checking to see what exactly is making this blow up

1/ I have put cairo.so and php_gtk2.so in the ini file and always crash
2/ I don't specify to use liglade i just compile php-gtk with this :
   ./buildconf &&
   ./configure --prefix=/usr &&
   make
3/ Yes i load it before

I made different try and compiling php-gtk with ./configure --prefix=/usr --
without-libglade
don't crash anymore

my libglade version is 2.6.4

So this is actually a bug with the php-gtk glade extension and loading

I'll take a look but it's not a high priority since libglade is deprecated - I would suggest you try migrating any glade code to gtkbuilder on any existing projects

The 2.0.1 version of php-gtk will no longer fixes.
We will work on version 3 of the php-gtk with gtk 3.

I'm gonna suspend this report as the PHP GTK project activity seems halted, if the activity picks backup for the project then this report should be re-opened.
