I'm trying to get the FDF shared module to work with PHP 4.0.6 on RedHat 7.1. I've installed fdftk.h to /usr/local/include and libfdftk.so to /usr/local/lib. The FDF module itself is located in /usr/lib/php4. Other modules are working fine, but when I start Apache with the FDF extension enabled, I get this error:
/usr/sbin/httpd: error while loading shared libraries: /usr/lib/php4/fdf.so: undefined symbol: FDFInitialize
The thing that's odd about this is that it appears that fdf.so is calling an undefined function, but it isn't even trying to reference libfdftk. Note that I have tried changing the capitalization of the library to libFdfTk, and that didn't help.
Thx in advance,
- James
