PDFLib - Builds & Installs, but doesn't show up in phpinfo()

Hi all, I've been banging my head against the wall for a few days and have finally decided to consult the list. Here's what I'm trying to do and what is happening: Platform: Various version of RH Linux, primary 6.2 (on an i586), but when that failed (repeatedly) I started trying it on a 7.1 box (Athlon). Goal: Build libpdf support into PHP for dynamic pdf generation What is Happening: -libpdf appears to configure, build, and install properly (from source) -php is rebuilt and appears to configure, build, and install properly -the output of phpinfo() does _not_ list any information on libpdf and libpdf functions do not work What I've Been Doing: Aside from beating my head against the wall I have been configuring libpdf builds with the following: ./configure --enable-shared-pdflib --enable-php --enable-cxx The output at the end of the ./configure process indicates that shared library, C++, and PHP support (among others) has been enabled. pdflib then appears to build and install properly with 'make; make install' * Note, I have been blowing away the pdflib source directory and re-untaring each time I do a build. For PHP builds I have been configuring with the following: ./configure --with-apxs --with-pdflib=/usr/local/lib --with-mysql=/usr/local/mysql/lib/mysql --with-zlib=/usr/include --with-ttf=/usr/lib --with-jpeg-dir=/usr/lib --with-tiff-dir=/usr/lib Again, it appears to configure properly. I then build PHP with ./make and ./make install. When apache is restarted and the output of testinfo() is checked pdflib is _not_ listed and pdflib specific functions do _not_ work. The configure options shown above are listed in the Configure Command portion of the output. Any pointers or tips would be most appreciated. I would be happy to provide any additional information that might explain what I've done. Thanks, Ben
