Maybe I'm doing something wrong, but I can't get the module working on a Debian Lenny amd64 system. When compiling the module I get the following warnings:

/tmp/gmagick/gmagick-1.0.3b3/gmagick_methods.c: In function "zim_gmagick_readimage":
/tmp/gmagick/gmagick-1.0.3b3/gmagick_methods.c:68: warning: cast to pointer from integer of different size
/tmp/gmagick/gmagick-1.0.3b3/gmagick_methods.c:68: warning: cast to pointer from integer of different size
/tmp/gmagick/gmagick-1.0.3b3/gmagick_methods.c: In function "zim_gmagick___construct":
/tmp/gmagick/gmagick-1.0.3b3/gmagick_methods.c:99: warning: cast to pointer from integer of different size
/tmp/gmagick/gmagick-1.0.3b3/gmagick_methods.c:99: warning: cast to pointer from integer of different size

I am actually able to compile, install and load the module, but when I try to use it, it doesn't work, and I get the following error in Apache's error.log:

apache2: magick/semaphore.c:525: LockSemaphoreInfo: Assertion `semaphore_info != (SemaphoreInfo *) ((void *)0)' failed.

Forgot to mention that the "cast to
pointer from integer of different size
" warning repeats a bunch of times for a lot of different functions.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read for *NIX and for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.


this was an issue with some versions of ImageMagick. Try upgrading ImageMagick and retry.

Hi, the backtrace is not needed. I selected the wrong resolution for the bug.
 [2010-01-27 15:10 UTC] spinn909 at gmail dot com

I'm guessing you meant 
GraphicsMagick, or do I also have 
to have ImageMagick installed? As 
for GraphicsMagick, I have the 
latest stable version, 1.3.8. 
Should I try with another, older 
 [2010-01-27 15:19 UTC]

sorry I meant GraphicsMagick. Getting confused while fixing bugs on both. I'll assign this to vitoc for further analysis

How does your build config look like? Optional features?

Can you paste your PHP code?
 [2010-01-28 10:02 UTC] spinn909 at gmail dot com

my GraphicsMagick build config is very basic, beforehand I installed a couple of libraries (JPEG, PNG, TIFF and FreeType) and built GraphicsMagick with --without-perl --enable-shared. Haven't used any of the other optional features. GM works normally and I am able to convert images from the command line.

My PHP code is also very simple, this is all it takes for the error to appear in my apache error.log:

$gm = new Gmagick('image.jpg');

Let me know if there's any other info you might need, or if there's something other I should try (install an additional library, try a different build config).

I managed to compile the extension in the end, using an older GraphicsMagick version (1.2.10).

By "compile" I actually meant "get it working and be able to convert images", sorry.

This bug has been fixed in SVN.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on

In case this was a website problem, the change will show
up on the website in short time.
Thank you for the report, and for helping us make PECL better.
