Strange Exception while generating PDF

[sensi]

I've load the current wkhtmltopdf-0.9.9-OS-X.i368 from the developer page (http://code.google.com/p/wkhtmltopdf/) and install SnappyBundle as described at install guide.
Everything looks fine but when I try to generate an pdf throw the snappy bundle I got following error:

The exit status code '5' says something went wrong:
stderr: "dyld: Symbol not found: __cg_jpeg_resync_to_restart

When I run the some command from the terminal: command: /usr/bin/wkhtmltopdf 'http://www.google.at' '/Applications/MAMP/htdocs/cosamui/web/data/test.pdf' it works as expected.

What can I do to solve this issue? Anyone other the same problem?

it's look like wkhtmltopdf lib got a symbols for file name that can't processed. Try for test filename 111.jpg

thx for your respond but the problem was the missing library files...

I've now solved the above issue by coping the library files into the MAMP lib folder. After that everything looks fine but:

The exit status code '5' says something went wrong:
stderr: "dyld: Library not loaded: /Applications/MAMP/Library/lib/libiconv.2.dylib

Ok I've fixed!

If someone get's similar exception like me, you have to check your MAMP library files under: /Applications/MAMP/Library/lib/

So in the folder above are many libs missing for the wkhtmltopdf to run correctly...
I've copy my system lib files into the MAMP lib folder and it works ;)

cp /usr/lib/* /Applications/MAMP/Library/lib/

Notice: That only works if you can run the wkhtmltopdf from the terminal successfully!

@sensi, did You have any issues after copying everything from sur/lib to MAMP lib folder? I tried it but now my Apache won't even start, it doesn't even say anything is wrong in the Log.

Ok, it seems that after following hints in this link (http://lists.macosforge.org/pipermail/macports-users/2010-November/022663.html) I've managed to come a buit further, but I'm stuck here:

dyld: Library not loaded: /Applications/MAMP/Library/lib/libiconv.2.dylib Referenced from: /Applications/MAMP/Library/lib/libxml2.2.dylib Reason: Incompatible library version: libxml2.2.dylib requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0

hi ragulka, no in my case it works. But I think I had luck that it works. Because on my iMac with new OS Lion I had some issues with the wkhtml stuff. This tool needs some more requirements which are not installed in an default mamp installation.

Best practice to use the wkhtmltopdf tool is, to run it on a linux installation. There I can install all required packages with yum or apt-get tool.

You also can try to install a new lamp by hand on your mac. Or try the XAMP for Mac. But I've no experience if it works on XAMP installation.

Hey @sensi, I solved this by switching from MAMP to the built-in PHP/Apache in OSX Lion

[sensi]

Hi @ragulka I think about it, but I have to create a lot of vHosts and modify the php.ini files or disable some mod... That's all in one place and it's very comftable and fit into my workflow using MAMP.

But you're right, if I install it on the build in PHP/Apache it will work without issues...

I had the same error as described above. I could run wkhtmltopdf from the command line just fine, but from php, with proc_open, it just produced an error code 5. The Apache logfile stated the same error as above, not finding the required libraries.
What helped in the end was to look into the environment variables set on my command line and compare it to the variables set in php.
The variable in question is named DYLD_LIBRARY_PATH, which was set to /Applications/MAMP/Library/Lib.
After setting this variable to /usr/lib, everything started to work just fine.

My command now looks something along this line:

$process = proc_open($command, $descriptorspec, $pipes, $cwd = null, array('DYLD_LIBRARY_PATH' => '/usr/lib'));

This allows wkhtmltopdf to load the system libraries, and not the MAMP specific libraries, which apparently do not work with wkhtmltopdf too well.

[sensi]

Thx @Kufi for your comment. Seems that works fine.

[kevindecapite]

I second @Kufi for the updated proc_open() command. Works like a charm now.

We maybe should have a way to configure this array from bundle/snappy. Thanks for all the input by the way.
