Remove the hardcoded module2dir mapping and use the results from echo-requires-recursive instead. Add README which briefly explains how module-deps is supposed to work. Add XSLT hacks to modules.mk.footer. Add cygdrive hacks to modules.mk.stub. Force string & embedstring to be built after xpcom since they now live in the xpcom hierarchy.

# First attempt at using module-graph.pl to generate
|
|
# a cvs checkout list, and building the resulting tree.
|
|
#
|
|
# bootstrap.pl starts with an "all.dot" requires map file
|
|
# and nothing else, and does the following:
|
|
# * Figures out the module dependencies for the module
|
|
# you want to build, via module-graph.pl.
|
|
# * Creates a list of directories from the modules via
|
|
# modules2dir.pl.
|
|
# * Checks out core config files, nspr, and module directories.
|
|
# * Based on this resulting tree, allmakefiles.sh is generated
|
|
# on the fly with a module name "bootstrap". modules.mk file
|
|
# generated with DIRS in leaf-first order.
|
|
# * A build is attempted with this configure option:
|
|
# --enable-standalone-modules=bootstrap --disable-ldap --disable-tests
|
|
#
|

# Example usage, to build xpcom:

|
|
# cvs co mozilla/tools/module-deps/bootstrap.pl

# mozilla/tools/module-deps/bootstrap.pl --module=xpcom
