Please Cc: me directly, if possible. Thanks! [This got long, but a search for "Synopsis:" (two of them) should give the gist.]
Originally, the machine (Linux 2.4.19-16mdk) had Mandrake 8 RPM's of PHP 4.2.3 and Apache 1.2.26 I was able to install LIBFDFTK.SO 5.0 and the .h file, symlinked to lower-case libfdftk.so so Linux would like it, edited /etc/ld.so.conf and did "ldconfig -v" to confirm its existence, and then downloaded PHP 4.2.3 source and compiled --with-fdftk=shared, shoved the resulting fdf.so into the extensions directory, used http://php.net/dl('fdf.so') and was succesfully using FDF to generate and process PDF Forms. I wrote a hack (sample at http://php.net/fdf_enum_values) to dis-assemble the PDF /Field object (Free Dimitry!) but it turned out to be not a good enough hack later when more complex PDF Forms made the /Field object be a "nested" array sort of thing. Thus, I needed fdf_open_string and friends, which was only available in PHP >= 4.3.0, in order to correctly process incoming forms. Downloaded Apache 1.2.28 source and PHP 4.3.2 source, and started compiling. Got Apache and PHP running okay, and even managed to configure and copy and symlink enough things so all the old httpd.conf files and php.ini file were being used, which got the server back to the original pre-FDF state. Alas, then the real problems started. 1) If I configure --with-fdftk=shared, then the resulting fdf.so file yields: /usr/local/apache/bin/httpd: relocation error: /usr/lib/php/extensions/fdf.so: undefined symbol: FDFInitialize Now I've used "diff" to convince myself that I really really *DO* have the "fdf.so" from 4.3.2 in /usr/lib/php/extensions And I've used "strings fdf.so" to verify that there is some kind of entry for FDFInitialize in there. Plus, I've used "strings LIBFDFTK.SO" to verify that there is some kind of entry for FDFInitialize in there as well. So I'll be damend if I can figure out why the symbol is undefined. Everybody involved seems to know about it, so why is it undefined? Who's supposed to have the function body? Which .so file was supposed to define it? How could it have managed to disappear in between 4.2.3 and 4.3.2? 2) Hoping that I could perhaps get FDF support in "static" and not lose the symbol, I re-compiled --with-fdftk (IE, not "shared") phpinfo() then showed me that FDF was there: fdf FDF Support enabled FdfTk Version 5.0 Alas, attempting to use fdf_create() yielded: FDF Error: An internal FDF Library error occurred Gee, that's a useful error message. Not. How about some detail, Adobe?! ldconfig -v *STILL* shows libfdftk.so getting loaded, so I don't think it has suddenly disappeared from the OS. The only other slightly weird thing is MySQL ended up being built-in to PHP (argh!) so I get a ton of messages about duplicate symbols when trying to load mysql.so But I've seen that before on other boxes and safely ignored it, and it sure shouldn't mess up FDF, right?... Does anybody know of anything that changed between 4.2.3 and 4.3.2 that would affect FDF support? Can anybody tell me for 100% sure where the FDFInitialize symbol was supposed to have been defined? I figure it would be in LIBFDFTK.SO, right? Is there some way to convince PHP that it should be looking at the modules loaded into Linux to find that -- It's already supposed to be doing that, right? Plan B: Does anybody have a better hack for dis-assembling PDF /Field objects recursively? I don't *REALLY* want to back-track to 1.2.26 and 4.2.3, but it's an option at least, if I can correctly parse the /Field object. Synopsis: PHP 4.2.3 + Apache 1.3.26 (RPM's) + fdf.so (source) works. PHP 4.3.2 + Apache 1.3.28 (source) + fdf.so (source) yields: /usr/local/apache/bin/httpd: relocation error: /usr/lib/php/extensions/fdf.so: undefined symbol: FDFInitialize PHP 4.3.2 + Apache 1.3.28 (source) + fdf (static) yields: FDF Error: An internal FDF Library error occurred If we can't fix those, anybody got a good hack for recursively dis-assembling the /Field object in a PDF, preferably into a 1-D array?
