$NetBSD: README,v 1.2 2008/10/27 07:22:22 mrg Exp $

|
|
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.
|
|
The expections 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
|
|
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
|
|
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.
