Relocation error for precompiled shared module extension.

I'd normally post this to the internals list but I think that this group is the new, more appropriate list. Correct me if I'm wrong :) Anyways I recently released my InterJinn project which included an optional extension for a large speed enhancement when working with templates. I received an email from a user indicating the following error: php: relocation error: /usr/lib/php4/php_interjinn.so: undefined symbol: _ecalloc I found similar information on Google suggesting, though not indefinately, that this is due to PHP version incompatibility. Can anyone verify that this is indeed the cause? For the sake of providing more complete information, the shared module works fine on my system and was compiled under linux with the following command lines: cc -fpic -DCOMPILE_DL_INTERJINN=1 \ -Iext/interjinn/ -Iinclude -Imain -I. -IZend -ITSRM \ -c -o ext/interjinn/interjinn.o ext/interjinn/interjinn.c cc -shared -L/usr/local/lib -rdynamic -o \ ext/interjinn/interjinn.so \ ext/interjinn/interjinn.o Thanks in advance, Rob. -- .------------------------------------------------------------. | InterJinn Application Framework - http://www.interjinn.com | :------------------------------------------------------------: | An application and templating framework for PHP.
