I'm attempting to install PIL under Redhat 7.3, to use in conjunction with the Photo product. I have gotten it installed and GIFs seem to work fine, but JPEGs do not. I'm trying to follow the "Using PIL with Zope" document found at http://www.zope.org/Members/regebro/PIL_zope/.

In Step 2, it instructs me to find out where my jpeglib is located using:
  ld -L/usr/local/lib -ljpeg -nostdlib
 ld -L/usr/lib -ljpeg -nostdlib

Neither of these steps work, but I do have a file called "libjpeg.so.62" in /usr/lib, which I understand is actually the jpeg library I want. I also have a "libz.so.1" which i'm going to assume is my Zlib library, needed in step 1.

OK, so I believe I have both the z and jpeg libraries on my system. I tried running the configure command from step 3 like this:
  ./configure --with-zlib=/usr/lib --with-jpeg=/usr/local/lib
and it completes with no errors.

Then I edit my Makefile and edit the LIBS= line to:
  LIBS= -L/usr/lib -lz -L/usr/lib -ljpeg -lm

When I run "make", it fails with "cannot find -lz". Since my z library is actually called "libz.so.1", I then tried changing the Makefile LIBS= line to "-llibz" and then "-llibz.so.1" but both still failed. So obviously i'm not grasping how to reference these libraries.

Can someone please point out what i'm obviously missing here?

Regards,
Dave
