PDF Functions

I finally got everything to install on RedHat 7, but I can't do anything with pdflib like I had expected. I get back Fatal error: Call to undefined function: pdf_new() in /var/www/html/pdfclock.php on line 7. Line 7 is $pdf = PDF_new(); This is rather frustrating that every time I try to install PHP on a machine it takes me a week to get it going. Here is what I have for the config from the srpm after modification as instructed earlier. ./configure \ --prefix=%{_prefix} \ --with-config-file-path=%{_sysconfdir} \ --disable-debug \ --enable-pic \ --enable-shared \ --enable-inline-optimization \ $* \ --with-exec-dir=%{_bindir} \ --with-regex=system \ --with-gettext \ --with-gd \ --with-jpeg-dir=%{_prefix} \ --with-png \ --with-zlib \ --with-gdbm \ --enable-debugger \ --enable-magic-quotes \ --enable-safe-mode \ --enable-sockets \ --enable-sysvsem \ --enable-sysvshm \ --enable-track-vars \ --enable-yp \ --enable-ftp \ --enable-wddx \ --with-mysql \ --with-xml \ --with-pdflib=/usr/lib/lipdf.so.0 \ --with-tiff Can someone look at this and tell me what else I need to put in to get this to work?
