<br><font size=2 face="sans-serif">Hello all,</font>
<br>
<br><font size=2 face="sans-serif"> I'm new to python and spent some time Friday installing PIL using the following configuration:</font>
<br><font size=2 face="sans-serif">OS: SunOS usatux29 5.8 Generic_108528-13 sun4u sparc SUNW,Sun-Fire-280R</font>
<br><font size=2 face="sans-serif">python: packaged with Zope (python 2.1.3)</font>
<br>
<br><font size=2 face="sans-serif">At any rate, I ran into several issues with the install. After being unable to find resolutions</font>
<br><font size=2 face="sans-serif">addressed in a mailing list anywhere I decided to post this in hopes of helping others down the line.</font>
<br><font size=2 face="sans-serif">At the end of this email I list the correct steps for installing PIL on a solaris box. Note, in the examples</font>
<br><font size=2 face="sans-serif">below you'll see Imaging-1.1.2. That was my playground. The same applies to Imaging-1.1.4</font>
<br>
<br><font size=2 face="sans-serif">=========================================================================</font>
<br><font size=2 face="sans-serif">BOTTOM LINE</font>
<br><font size=2 face="sans-serif">Most of my problems were because I did not have the directory containing</font>
<br><font size=2 face="sans-serif">libjpeg in my LD_LIBRARY_PATH environment variable.</font>
<br>
<br>
<br><font size=2 face="sans-serif">=========================================================================</font>
<br><font size=2 face="sans-serif">Symptons I received as a result, when I ran configure:</font>

<br>
<br><font size=2 face="sans-serif">Then, when running make, I received the following errors:</font>

<br>
<br>
<br><font size=2 face="sans-serif">I looked in my config.log and found the C code used by configure to test these </font>
<br><font size=2 face="sans-serif">parts of my system. The reason all of these tests were failing was that configure</font>
<br><font size=2 face="sans-serif">was passing -ljpeg as a gcc compiler option. Since I did not have libjpeg in my</font>
<br><font size=2 face="sans-serif">ld path, the compilation failed and I received the errors above.</font>

<br>
<br><font size=2 face="sans-serif">Looks much better now!</font>

<br><font size=2 face="sans-serif">=========================================================================</font>
<br><font size=2 face="sans-serif">SUMMARY OF STEPS FOR INSTALLING PIL ON SOLARIS:</font>
<br>
<br><font size=2 face="sans-serif">gtar zxvf Imaging-1.1.2.tar.gz</font>
<br><font size=2 face="sans-serif">cd Imaging-1.1.2/libImaging</font>

<br><font size=2 face="sans-serif">./configure</font>
<br><font size=2 face="sans-serif">edit Makefile and add -fPIC to the end of the CFLAGS variable ( about line 36? )</font>

<br><font size=2 face="sans-serif">make -f Makefile.pre.in boot</font>
<br><font size=2 face="sans-serif">edit Setup.in and added -L/opt/sfw/lib to the libjpeg specification, </font>

<br>
<br>
<br><font size=2 face="sans-serif">=========================================================================</font>
<br><font size=2 face="sans-serif">SUGGESTIONS:</font>
<br><font size=2 face="sans-serif">First, to the authors of PIL, thanks for the software. </font>
<br><font size=2 face="sans-serif">I am grateful for the use of it. I hope that these suggestions will be perceived</font>
<br><font size=2 face="sans-serif">as such and not complaining.</font>
<br>
<br><font size=2 face="sans-serif">1. The README gives the appearance that the jpeg library is optional, when it's not since</font>
<br><font size=2 face="sans-serif">configure doesn't produce the correct output without libjpeg in the ld path.</font>
<br><font size=2 face="sans-serif">"""</font>
<br><font size=2 face="sans-serif"> If you need JPEG and/or PNG support, make sure to get and build</font>
<br><font size=2 face="sans-serif"> the necessary external libraries:</font>
<br>
<br><font size=2 face="sans-serif"> - for JPEG support, get the IJG JPEG library, version 6a or 6b.</font>
<br>
<br><font size=2 face="sans-serif"> You can find this library here:</font>
<br>
<br><font size=2 face="sans-serif"> http://www.ijg.org</font>
<br><font size=2 face="sans-serif"> ftp://ftp.uu.net/graphics/jpeg/</font>
<br><font size=2 face="sans-serif">"""</font>
<br><font size=2 face="sans-serif">Should this be changed to remove the If?</font>
<br>
<br><font size=2 face="sans-serif">2. The configure process should run a test specifically for libjpeg and fail with an error</font>
<br><font size=2 face="sans-serif">message stating that it could not be loaded and is needed by the program. If this</font>
<br><font size=2 face="sans-serif">were done at the beginning of the build process, I believe it would be enough</font>
<br><font size=2 face="sans-serif">information for an admin or developer to make the adjustments necessary to install PIL.</font>
<br>
<br><font size=2 face="sans-serif">3. Is there a way to remove the jpeg and z library dependencies for the ASNI C header check</font>
<br><font size=2 face="sans-serif">and the sizeof checks? I don't know the GNU Autoconf toolset very well, but</font>
<br><font size=2 face="sans-serif">I think a check for sizeof should only fail if the sizeof C call fails, and not for a </font>
<br><font size=2 face="sans-serif">missing library that isn't used in the actual C code.</font>
<br>
<br>
<br><font size=2 face="sans-serif">4. I didn't have xv on my system, so I received a non-fatal error</font>
<br><font size=2 face="sans-serif">while running 'make check'. It would be useful if it were documented in the</font>
<br><font size=2 face="sans-serif">README or elsewhere that a successful make check depended on xv.</font>
<br>
<br><font size=2 face="sans-serif">Well, I hope this information is found useful by others. If I haven't got something quite right,</font>
<br><font size=2 face="sans-serif">please let me know.</font>
<br>
<br><font size=2 face="sans-serif">Thanks,</font>
