Installing PDFLib when compiling from source
From Sfiabwiki
First, download and install PDFLib Lite from:
http://www.pdflib.com/products/pdflib/download-source.html
Now download the PHP source from:
http://www.php.net/downloads.php
configure php, here's the configure options I use
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql --enable-exif --with-gd --with-zlib --enable-gd-native-ttf --with-freetype-dir=/usr --with-jpeg-dir=/usr --with-imap-ssl --with-kerberos --with-pgsql --enable-mbstring=all --enable-soap --with-curl --with-curl-wrappers --with-pdflib=/usr/local
The most important one here is the last one, set it to the location that you install pdflib into... next BEFORE you build anything, run the following:
pear download pdflib tar -zvxf pdflib-2.0.5.tgz mv pdflib-2.0.5/* ext/pdf
now you can
make make install
as normal.
