$NetBSD: README,v 1.3 2009/01/13 17:52:32 jmmv Exp $
build 32 bit compat libraries and ld.elf_so for amd64 and sparc64 builds. two issues remain: - LIBDPLIBS isn't working correctly, requiring hand-holding builds - libc, libipsec, and libpcap have yacc issues, also requiring hand holding ideally this will be replaced with a better method that can handle more than one compat target, but i can't get that working yet. see the README file for mroe details.

This directory contains Makefile fragments that will build all of the
NetBSD libraries in 32-bit mode and install them into /usr/lib/<arch>
and also install a /usr/libexec/ld.elf_so-<arch>.
This is current only supported for the amd64 and sparc64 platforms,
where <arch> is "i386" or "sparc" respectively. (It could be used to
build MIPS o32 libraries on n32 system, but not both n32 and o32 on
a n64 system. It only supports one extra target.)
Most of the makefiles here were built with the "build-makefiles" script.
Fix typo.

The exceptions are lib/csu/Makefile and ld.elf_so/Makefile.

The method used is the:
- evaluate some local variables
- switch .CURDIR
- include original Makefile,
- evaluate some variables
- switch .CURDIR back
that is used by crunchgen to build eg, installer media or /rescue.
TODO:
- some yacc issue -- libc, libipsec and libpcap need "make" run
to generate headers properly, otherwise it complains about
update this to match reality.

no way to get to foo.h. this is currently hacked by putting
a rule "foo.h: foo.c" in the (generated) makefiles

- there's an ugly hack to make libpam build correctly again the
update this to match reality.
2008-10-27 10:22:22 +03:00
right libc. ld.elf_so has a similar (but less ugly hack)
- not sure that /usr/lib/{i386,sparc}{,/i18n} are created
properly yet

Future work
Ideally this should be able to handle any number of compat targets.
Perhaps using a "force MAKEOBJDIR, and run-run make" solution will
work, but my initial attempts got me no where. If not, perhaps
build-makefiles could be expanded to be used at run-time in such
a per-compat target obj-dir.
