Need help with the build system

Hello all, I'm trying to make a module for php-4.2.1 but i'm having difficulties with the build system. I perform the following steps: 1. extract a fresh source tree (php-4.2.1) 2. go to ext/ and run ./ext_skel --extname=mymodule 3. edit config.m4 and uncomment some lines to make this: PHP_ARG_ENABLE(memusage, whether to enable memusage support, dnl Make sure that the comment is aligned:

[  --enable-memusage           Enable memusage support])

if test "$PHP_MEMUSAGE" != "no"; then PHP_EXTENSION(memusage, $ext_shared) fi 4. go to the root of the source and run ./buildconf 5. run ./configure --enable-mymodule 6. run make, and then i get the error 'make: *** No targets specified and no makefile found. Stop.' So it seems configure doesnt create a Makefile. I exactly followed the steps outlined in the manual and the output of ext_skel. Can anyone tell me whats going wrong here? Thanks in advance, Hans Rakers Parse BV, the Netherlands
