You can easily install PDFlib on linux server.

==========================

cd /usr/local/src/

ftp://ftp.uni-hannover.de/pub/mirror...e-X.X.X.tar.gz

tar -zxf PDFlib-Lite-X.X.X.tar.gz

cd PDFlib-Lite-X.X.X

./configure

make

make install

mount -o remount rw /tmp

pecl install pdflib

mount -o remount noexec,nosuid,rw /tmp

php -m | grep pdf

if pecl fails try the one below.

tar -zxvf pdflib-2.1.7.tgz

cd pdflib-2.1.7

phpize

./configure --with-pdflib=/usr/local/

make

make install

Just add extension = "pdf.so" to the server php.ini & restart apache service.
