Building multi- ABI libraries for NetBSD platforms.

Building multi-ABI libraries for NetBSD platforms.

src/compat has a framework to (re)build the libraries shipped with

Line 15 The basic premise is to re-set $MAKEOBJD

underneath src/compat and rebuild the libraries with a different set

of options. Each platform wanting support should create their port

subdirectory directly in src/compat, and then one subdirectory in here

for each ABI required. e.g., src/compat/amd64/i386 is where we build

for each ABI required, e.g., src/compat/amd64/i386 is where we build

the 32-bit compat libraries for the amd64 port. In each of these

subdirs, a small Makefile and makefile fragment should exist. The

subdirectories, a small Makefile and makefile fragment should exist. The

Makefile should set BSD_MK_COMPAT_FILE to equal the fragment, and then

include "../../compatsubdir.mk" Eg, amd64/i386/Makefile has:

include "../../compatsubdir.mk". E.g., amd64/i386/Makefile has:

BSD_MK_COMPAT_FILE=${.CURDIR}/bsd.i386.mk

Line 60 ld.elf_so) to build with this ABI.

archdirs.mk holds the list of subdirectories for each port.

Makefile.compat has the basic framework to force the right paths for

library and ld.elf_so linkage. It contains a hack to create subdirs

library and ld.elf_so linkage. It contains a hack to create subdirectories

in the build that should be fixed.

dirshack/Makefile is a hack to get objdirs created timely, and should
