FW: Problem: Undefined symbols

Mr. Noelle, I understand your discussion of your problem below. I executed ldd -r {path}/libphp4.so and found that I too enjoy quite a number of undefined symbols. In my case, the first offender is the undefined symbol uncompress. What steps did you take to overcome the problem?

I just thought I'd post the solution in case anyone else runs into it. ldd -r {path}/libphp4.so libdl.so.2 => //lib/libdl.so.2 (0x40147000) libpq.so.2.1 => not found libmysqlclient.so.10 => not found libresolv.so.2 => //lib/libresolv.so.2 (0x4017f000) libm.so.6 => //lib/libm.so.6 (0x40190000) [... libcrypt, libnsl, libc, libz, lib/ld-linux ...] undefined symbol: ... (/var/lib/apache/libexec/libphp4.so) [... MANY undefined symbols ...] Note the second and third libraries, marked "not found". It turned out that two of the shared libraries I was trying to link against, MySQL's libmysqlclient and PostgreSQL's libpq, weren't being found by ld.so. What threw me off was the way Apache named libphp4.so with its "shared object not open" error, when the shared objects it couldn't open were two _other_ libraries linked from libphp4.so. I'm no autoconf expert, and I don't know if there's a reliably portable way to do this, but it would be nice if configure could make sure the shared libraries being linked against could actually be found. The misleading "libphp4.so ... shared object not open" and that particularly helpful "syntax error" are, of course, an Apache problem. -- -Dave Noelle, dave@Straylight.org -the Villa Straylight, http://www.straylight.org Coalition Against Unsolicited Commercial Email == http://www.cauce.com Disclaimer: Any similarities to the opinions of any real or hypothetical entities, living, dead, or otherwise, are clearly the reader's own delusion.
