$NetBSD: README.mknative,v 1.5 2011/09/26 02:36:19 christos 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/crtstuff4 do "nbmake-MACHINE depend all install"
|
||||
|
||||
5. In src/lib/csu, src/gnu/lib/libgcc4, 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.
|
||||
|
||||
NOTE: this step writes files under src/external/gpl3/gdb/bin/gdb, so you
|
||||
need to do it in a writable src tree!
|
||||
|
||||
7. Try out a full build using "nbmake-MACHINE" in
|
||||
src/external/gpl3/bin/gdb; the result should include a native GDB.
|
||||
|
||||
8. If all is well, commit the glue files and directories added to
|
||||
src/external/gpl3/gdb/bin/gdb.
