I'm desperately trying to get PIL going under Zope, so I can run the
Photo and Photo Folder products.
Everything seems to be working fine as long as I stick to .gif
images-- I can create a photo folder, add photo docs, pregenerate
thumbnails, etc.
However, it breaks when I try to use a .jpg image. When I try to
create a photo doc with a .jpg, I get the following error:
* Module PIL.Image, line 255, in _getdecoder
IOError: decoder jpeg not available
OK, so i've searched all the lists I can find, and it seems as if i
don't have JPEG support compiled into PIL.
If I go to /var/zope/lib/python2.1/site-packages/PIL and run "ldd
_imaging.so", I get:
libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
I believe I should have a line in there like "libjpeg.so.6 =>
/usr/lib/libjpeg.so.6". But I don't. So I believe this means that I
need to recompile the PIL libraries? I went back to my PIL /libImaging
folder and tried manually editing the ImConfig.h file. I uncommented
the line
/* Define if you have the IJG jpeg library (-ljpeg). */
#undef HAVE_LIBJPEG */
then re-run make, but the new "_imaging.so" still doesn't seem to be
linked to libjpeg.so.6.
I think i'm close, but I can't quite get there. How do I recompile PIL
with JPG support? Sorry for being an idiot here, but can someone help
drag me the last 10 feet to victory?
