$NetBSD: README.mknative,v 1.1 2006/06/02 15:33:34 nathanw Exp $

This file describes how to use the cross-compiler to generate the
|
|
native files for GDB on a target platform.
|
|
|
|
NOTE: DO NOT RUN "mknative" BY HAND! It requires the Makefile in this
|
|
directory to set up certain environments first.
|
|
|
|
Since libc's features change over time, the config.h files can change as a
|
|
result; thus the instructions below are the same no matter whether
|
|
bootstrapping on a cross or native host. This is important: even on a
|
|
"native" host, you should bootstrap the toolchain by building from an
|
|
up-to-date source tree to a $DESTDIR using the exact same instructions.
|
|
|
|
In these notes, MACHINE is the $MACHINE of the target. These files can be
|
|
cross-generated. Though a $MACHINE_ARCH all uses the same config files, you
|
|
must pick a specific $MACHINE so that building the requisite bits below will
|
|
work.
|
|
|
|
1. Set MKMAINTAINERTOOLS=yes in mk.conf. (Needed so that src/tools/gettext
|
|
gets built, eliciting proper HAVE_*GETTEXT* defns in config.h files.)
|
|
|
|
2. Build and install a cross toolchain (via "build.sh -m MACHINE tools").
|
|
|
|
3. At top level, do "nbmake-MACHINE do-distrib-dirs obj includes".
|
|
|
|
4. In src/gnu/lib/crtstuff3 do "nbmake-MACHINE depend all install"
|
|
|
|
5. In src/lib/csu, src/gnu/lib/libgcc3, and src/lib, do "nbmake-MACHINE all install".
|
|
|
|
6. In src/tools/gdb, do "nbmake-MACHINE obj native-gdb".
|
|
|
|
This will do a full configury in ${.OBJDIR}/.native that is a "Canadian"
|
|
cross toolchain (--build reflects the host platform, but --host and
|
|
--target are the target). The result is a tree that would build a
|
|
native-to-NetBSD GDB on a cross host, and mknative pulls glue data
|
|
from this.
|
|
|
|
7. Try out a full build using "nbmake-MACHINE" in
|
|
src/gnu/usr.bin/gdb6; the result should include a native GDB.
|
|
|
|
8. If all is well, commit the glue files and directories added to
|
|
src/gnu/usr.bin/gdb6.
