Prioritize local includes and libraries This fixes #35. 2015-01-22 09:43:28 -05:00			`# rules to build a program`
Add some .mk stubs to impersonate bsk .mk files to make writing our Makefiles easier. libeinfo, librc and rc now have their own seperate directories. More work is needed to tidy this up though. 2008-01-05 19:25:55 +00:00			`# based on FreeBSD's bsd.prog.mk`

NetBSD doesn't include /lib in its link path, so we need to add it as an RPATH. 2008-01-11 17:21:21 +00:00			`# Some systems don't include /lib in their standard link path`
			`# so we should embed it if different`
Ensure we link against libraries in /lib instead of anywhere else and always use the linker in /libexec instead of anywhere else. 2008-01-11 23:40:22 +00:00			`# This is currently hardcoded for NetBSD which has two dynamic linkers`

use immediate evaluation for shell calls This reworks the shell calls in the makefiles to use immediate evaluation and should improve parallel building.

Allow depend creation again. This doesn't work on GNU make, but does on all others. 2008-01-07 14:20:13 +00:00			`all: depend ${PROG}`

Use pattern rules instead of suffix rules Rework the makefiles to use pattern rules instead of suffix rules. This is the preferred way to write implicit rules according to the gnu make manual. 2011-10-28 11:14:44 -05:00			`%.o: %.c`

Allow depend creation again. This doesn't work on GNU make, but does on all others. 2008-01-07 14:20:13 +00:00
Enable use of .depend on gmake. Also, generate extra dependencies for our shared libraries. 2008-10-20 12:09:14 +00:00			`extra_depend:`

Rejig the build system a little so we have per ok defs per system. Probably easier in the long run. 2008-03-19 15:22:20 +00:00			`include ${MK}/sys.mk`
			`include ${MK}/os.mk`
Allow for OS and SUBOS folders so we can introduce NetBSD scripts whilst keeping BSD for all BSD's. 2008-01-10 16:35:59 +00:00			`include ${MK}/depend.mk`
