# $NetBSD: create.mk,v 1.3 2008/02/13 09:11:01 rillig Exp $
|
Separate out the part of bsd.tools.mk that actually created the tools
into a new file pkgsrc/mk/tools/create.mk. This leaves bsd.tools.mk
as a file that pulls in all of the other ones. Also move the
tools-related targets from bsd.pkg.mk into bsd.tools.mk.
The tools cookie file has been removed, as well as hooks for
{pre,do,post}-tools. Instead, there is now only a single public target
"tools" which may be invoked. Invoking "tools" will always cause all
of the tools in ${TOOLS_DIR} to be created.
The "tools" step has been moved and is now just after the "depends"
step and before sources are extracted. This is the earliest place
where the "tools" step can be taken, and it allows the created tools
to be used in all steps/phases after it, starting with "extract". As
a consequence, we should just invoke tools by their bare names in
targets, e.g. awk, sed, patch, etc., instead of with the ${VARIABLE}
names, e.g. ${AWK}, ${SED}, ${PATCH}, etc.

# TOOLS_CMD.<tool> is the path to the tool under ${TOOLS_DIR}. This

# in the wrapper script that is executed when <tool> is called.
|
|
|
|
|
# This variable is optional, and if left unspecified, then this

# TOOLS_NOOP is a list of tools that do nothing and return true.

# TOOLS_BROKEN is a list of tools that do nothing and return false.

# TOOLS_GNU_MISSING is a list of tools for which the GNU missing
