I downloaded to /usr/local/src/fdftk4_05 then copied fdftk.h to /usr/local/include/FdfTk.h and libfdftk.so to /usr/local/lib/libFdfTk.so.
Until I got the capital "F" and "T" letters correct, I got the same error as mentioned. However, with the capitals sorted, the build command command:-
./configure --with-fdftk --with-apxs=/usr/sbin/apxs
worked fine. I then went on to "make" and "make install".
Unfortunately, when I then tried to start Apache, I got the message:-
Syntax error on line 210 of /etc/httpd/conf/httpd.conf:
Cannot load /usr/lib/apache/libphp4.so into server: libFdfTk.so: cannot open shared object file: No such file or directory.
Versions: - php-4.0.4.pl1, Apache-1.3.12.
Any thoughts out there?
