After 4 or so hours of troubleshooting, I thought I would share my solution while it is fresh in my head.
My system is a new Server (intel) running Solaris 10, and all dependent software packages from http://www.sunfreeware.com to run apache-2.2.20-sol10-x86-local and php-5.3.6-sol10-x86-local with Joomla_1.7.0-Stable-Full_Package.zip.
I got the site up and running, loaded a cool template,installed Phoca Gallery, loaded a few images, and bammmm... Error creating thumbnail. I wasn't the first with this problem....
While find a solution, I came across chmod_set.sh and chmod_unset.sh which are a good idea when you're not making changes to the site (to lock down the filesystem from write access via apache). Permissions were not my problem.
Info.php showed me that my PHP was installed correctly, and that GD was there with all applicable modules enabled....
I enabled display_errors = On in my php.ini, and started to see the problem on screen.
Warning: imagecreatefromjpeg(): gd-jpeg: JPEG library reports unrecoverable error: in /data/www/administrator/components/com_phocagallery/libraries/phocagallery/image/imagemagic.php on line 214 Warning: imagecreatefromjpeg(): '/data/www/images/phocagallery/VEG2.JPEG' is not a valid JPEG file.
Well, my JPEG was a valid file, and converting it to a PNG, and back to a JPEG was not the solution. Same error applied.
I think looked in my apache error_log and got the following:
[Wed Sep 14 22:12:38 2011] [notice] Apache/2.2.20 (Unix) mod_ssl/2.2.20 OpenSSL/1.0.0e DAV/2 PHP/5.3.8 configured -- resuming normal operations
Wrong JPEG library version: library is 62, caller expects 80
I'm a little closer... Looks like a version problem somewhere...
After much trial and error, I ended up downloading the source code for php, and building it myself with the following:
Code: Select all
cd /data/downloads
wget http://us2.php.net/get/php-5.3.8.tar.gz/from/us.php.net/mirror
gunzip php-5.3.8.tar.gz
tar -xvf php-5.3.8.tar.gz
cd php-5.3.8
make clean

make
make test
make install
/usr/local/apache2/build/libtool --finish /data/downloads/php-5.3.8/libs
root@www 22:18 /data/downloads>locate jpeglib.h
/usr/include/jpeglib.h
/usr/local/include/jpeglib.h
/usr/sfw/include/mozilla/jpeg/jpeglib.h
I did a "more /usr/include/jpeglib.h" and found it was for jpeg version 6.2, and "more /usr/local/include/jpeglib.h" was for 8.0. So I moved the 6.2 library file (mv /usr/include/jpeglib.h /usr/include/jpeglib.h.bak) and created a symbolic link to replace it (ln -s /usr/local/include/jpeglib.h /usr/include/jpeglib.h).
I then rebuilt PHP with the same process outlined above, and restarted apache.... Whola, JPEG thumbnail creation works.
This is a pretty tough problem (at least for me) to isolate down to a .h file. But it makes sense that PHP may grab one over the other when building. I'm not sure how it all works, nor do I care, but I'm happy that I can at least test the functionality of Phoca, which better work!
