Compile troubles, impossible to create .so extensions with current cvs?

Hi, First, I'm not well into compiling PHP in specific ways, so consider these semi-newbie questions. I hope someone has an idea about what could be going on, if so, please drop me a line. My system is Linux Debian unstable, everything relevant is up-to-date. My compile-line is: ./configure --disable-static --with-mysql=shared * Result on 406 dist: works fine, mysql.so appears in modules dir * Any recent snapshot: mysql.a and mysql.la appear in modules, but no .so * Latest cvs after ./buildconf: same result * getting back to 406 by means of CVS, ./buildconf fails: cvs up -r PHP_4_0_6 && ./cvsclean && make clean && make distclean [jeroen@richard]~/php/php4> ./buildconf buildconf: checking installation... buildconf: autoconf version 2.52 (ok) buildconf: automake version 1.5 (ok) buildconf: libtool version 1.4 (ok) rebuilding Makefile templates rebuilding configure ./aclocal.m4:814: error: m4_defn: undefined macro: _m4_divert_diversion ./aclocal.m4:360: PHP_SUBST is expanded from... ./aclocal.m4:814: the top level rebuilding main/php_config.h.in ./aclocal.m4:814: error: m4_defn: undefined macro: _m4_divert_diversion ./aclocal.m4:360: PHP_SUBST is expanded from... ./aclocal.m4:814: the top level autoconf: tracing failed Thanks a lot Jeroen
