The final commit for the first phase of PowerPC support. This adds the config stuff needed to build kernels. Reviewed by: obrien 2001-06-17 09:39:44 +00:00			`# Makefile.powerpc -- with config changes.`

Make the necessary changes so that an ELF kernel can be built. I have successfully built, booted, and run a number of different ELF kernel configurations, including GENERIC. LINT also builds and links cleanly, though I have not tried to boot it. The impact on developers is virtually nil, except for two things. All linker sets that might possibly be present in the kernel must be listed in "sys/i386/i386/setdefs.h". And all C symbols that are also referenced from assembly language code must be listed in "sys/i386/include/asnames.h". It so happens that failure to do these things will have no impact on the a.out kernel. But it will break the build of the ELF kernel. The ELF bootloader works, but it is not ready to commit quite yet. 1997-04-22 06:55:47 +00:00
Put in an initial %VERSREQ field. This will cause existing config(8)'s to give a non-fatal warning about unknown directives, so there is no hurry to rebuild config(8) yet, apart from shutting up the warning. 1997-10-22 00:48:36 +00:00			`# Which version of config(8) is required.`

Add option for compiling in a 8x16 font. 1997-07-25 11:53:30 +00:00			`STD8X16FONT?= iso`

Allow the source root `S' to be overridden by defining it only when it isn't already defined. It enables config(8) to create the kernel build directory where it wants. 1999-10-30 09:28:27 +00:00			`.if !defined(S)`
Change all #includes to follow the current Berkeley style. Some of these ``changes'' are actually not changes at all, but CVS sometimes has trouble telling the difference. This also includes support for second-directory compiles. This is not quite complete yet, as `config' doesn't yet do the right thing. You can still make it work trivially, however, by doing the following: rm /sys/compile mkdir /usr/obj/sys/compile ln -s M-. /sys/compile cd /sys/i386/conf config MYKERNEL cd ../../compile/MYKERNEL ln -s /sys @ rm machine ln -s @/i386/include machine make depend make 1994-08-13 03:50:34 +00:00			`.if exists(./@/.)`

Factor the common parts of the Makefile.foo files. This introduces two new files: kern.pre.mk, which contains most of the definitions, and kern.post.mk, which contains most of the rules. I've tested this on i386 and pc98. I have had feedback on the sparc64 port, but no reports from anybody on alpha, ia64 or powerpc. I appologize in advance if I've broken you.

Move the -I../../../include or -I/usr/include to the last entry on the cc arguments. Otherwise ipfilter's bogus #include lines will compile reference /usr/include/netinet/ip_frag.h etc. 2001-06-12 06:06:18 +00:00
Removed COPTS support from kmod.mk and kern.pre.mk. COPTS support in bsd.prog.mk is preserved but discouraged. 2004-08-13 14:30:26 +00:00			`CFLAGS+= -msoft-float`
