process in README.SELF-CONTAINED-EXTENSIONS broken?

I just grabbed PHP from CVS and tried to go through the procedure outlined in README.SELF-CONTAINED-EXTENSIONS and found that it doesn't work. Can someone help? I'm looking at revision 1.10 of the README. The php4 module's checked out into my ~/devel directory. So under CONVERTING AN EXISTING EXTENSION, I do mkdir /tmp/newext cd /tmp/newext cp -rp ~/devel/php4/ext/sockets/* . phpize phpize gives some warnings: aclocal: macro `AC_ADD_LIBPATH' defined in acinclude.m4 but never used aclocal: macro `AC_ADD_LIBRARY' defined in acinclude.m4 but never used aclocal: macro `AC_ADD_LIBRARY_WITH_PATH' defined in acinclude.m4 but never used aclocal: macro `AC_ADD_INCLUDE' defined in acinclude.m4 but never used You should update your `aclocal.m4' by running aclocal. I ran aclocal, which gave the same output as phpize, save for the last line; finally: ./configure configure dies with: configure: error: can not find sources in . or .. I've tried running buildconf and configure in the cvs working directory, but still no dice. Can anyone help? B -- Brian Lalor blalor@ithacabands.org blalor@jabber.ithacabands.org
