-Finally you'll require a compiler and assembler/linker:
+while the compiler (gcc) and assember (binutils) can be found at your
+favorite gnu ftp site. I used versions:

- o Unpack the bsd source code (if you haven't already)
-
- $ cd .../scratch
- $ mkdir bsd-src
- $ cd bsd-src
- $ for d in /cdrom/bsdisc_12_95_disc2/NetBSD-1.1/source/*11
- do
- echo $d
- cat $d/*.?? | gunzip | tar xf -
- done
-
- Flatten the directory structure a little.
-
- $ mv usr/src/* .
- $ rmdir usr/src usr
- $ cd ..
-
-
- o Unpack/build/install binutils
+ o Prepare the destination directory ready for installation.
- $ cd .../scratch
- $ gunzip < binutils-2.6.tar.gz | tar xf -
- $ cd binutils-2.6
-
- Optionally apply the note patch
-
- $ gunzip ../binutils-2.6+note.diff.gz | patch
-
- Then continue with the build
+ Firstly create many of the needed directories (some are
+ created automatically later):
- $ ./configure --target=powerpc-unknown-eabi \
- --prefix=/applications/psim
- $ make
- $ make install
- $ cd ..
- $ rm -rf binutils-2.6
-
- This has the intended side effect of partially populating
- the psim directory tree which makes follow on steps easier.
-
-
- o Fill out the install directory with a few additions (if
- install -d works, this can be simplified).
-
- $ mkdir \
+ $ for d in \
+ /applications/psim \
/applications/psim/bsd-root \
/applications/psim/bsd-root/usr \

+ do test -d $d || mkdir $d ; done
-
- o Make the bsd and gnu include directories point to the same
- location.
-
+ Next, link the BSD and GNU include directories together.
GCC expects include files to be in one location while the
bsd install expects them in a second. The link is in
the direction below because bsd's install also insists on
a directory (not a link) for its install destination.
- $ ln -s ../bsd-root/usr/include \

o Build/install Berkeley make
- In building Berkeley make from the NetBSD-1.1 source tree
- a number of problems may be encountered.
+ The tar archive make.tar.gz contains a recent snapshot
+ of bmake from the NetBSD source tree. The notes below
+ describe how to build/install it. If you have access
+ to an even more recent version of bmake, use that.
- These problems have been fixed in NetBSD-current (after
- 4/2/96 (ie start Feb)) you should probably obtain that
- version of make. Alternatively, you can try following the
- notes below that got make working on a Solaris-2.5/x86
- host.
+ Unpack the source code:
$ cd .../scratch
- $ cd bsd-src/usr.bin/make
- $ pwd
- .../scratch/bsd-src/usr.bin/make
-
- Copy/stub some additional include files that your host may not
- have.
+ $ gunzip < make.tar.gz | tar xf -
+ $ cd make
- $ cp ../../include/ranlib.h ranlib.h
- $ mkdir sys
- $ cp ../../sys/sys/cdefs.h sys/cdefs.h
- $ mkdir machine
- $ touch machine/cdefs.h
+ Apply the patch in make.diff.gz that fixes a minor
+ problem with a build under Solaris (by now it should
+ be fixed in the NetBSD-current source tree).
- Edit/fix some of the BSDisms. The patch file indicated
- contains fixes I found when compiling on my host, your
- host will probably differ.
+ $ gunzip < ../make.diff.gz | more
+ $ gunzip < ../make.diff.gz | patch
- $ gunzip < ../../../clayton.usr.bin.make.diff.gz | patch
+ Build it
- Build it with some extra flags (again your flags will differ):
-
- $ make -f Makefile.boot CC='gcc -g -DPOSIX'
+ $ make -f Makefile.boot 'CC=gcc -g -DPOSIX'
With bmake built, install it into the target specific bin
directory:
$ cp bmake /applications/psim/powerpc-unknown-eabi/bin/make
- $ cd ../../..
-
-
- o Patch/install Berkeley make's include (mk) files.
-
- $ cd .../share
- $ cd bsd-src/share
- $ tar cf - mk | ( cd /applications/psim/bsd-root/usr/share \
- && tar xf - )
- $ cd ../..
+ $ cd ..
+ $ rm -rf make
o Set up a number of wrapper scripts for bmake so that it works.
a number of BSD specific commands. To get around this
several wrapper scripts are available.
- powerpc-unknown-eabi-make (clayton.make)
+ powerpc-unknown-eabi-make (clayton.make.sh)
Front end to Berkeley make setting it up for a
cross compilation
- /applications/psim/bin/powerpc-unknown-eabi-make
+ $ cp clayton.make.sh \
+ /applications/psim/bin/powerpc-unknown-eabi-make
+ $ chmod a+x \
+ /applications/psim/bin/powerpc-unknown-eabi-make
- chown (clayton.chown)
+ chown (clayton.chown.sh)
Wrapper that does not do any thing.
Avoids the need to be root when installing.
- /applications/psim/powerpc-unknown-eabi/bin
+ $ cp clayton.chown.sh \
+ /applications/psim/powerpc-unknown-eabi/bin/chown
+ $ chmod a+x \
+ /applications/psim/powerpc-unknown-eabi/bin/chown
- install (clayton.install)
+ install (clayton.install.sh)
Wrapper to strip away a number of bsd specific install
arguments.
- /applications/psim/powerpc-unknown-eabi/bin/install
+ $ cp clayton.install.sh \
+ /applications/psim/powerpc-unknown-eabi/bin/install
+ $ chmod a+x \
+ /applications/psim/powerpc-unknown-eabi/bin/install
- lorder (clayton.lorder)
+ lorder (clayton.lorder.sh)
Tweaked lorder script that will use nm etc from
binutils.
- /applications/psim/powerpc-unknown-eabi/bin/lorder
+ $ cp clayton.lorder.sh \
+ /applications/psim/powerpc-unknown-eabi/bin/lorder
+ $ chmod a+x \
+ /applications/psim/powerpc-unknown-eabi/bin/lorder
+
+
+ printf (?)
+
+ Some operating systems don't include the program
+ printf. If you host doesn't have one, then a
+ good source is the gnu sh-utils version.
+
+ Again, if that program is missing, then I suggest
+ installing it onto the powerpc specific program
+ directory:
+
+ /applications/psim/powerpc-unknown-eabi/bin
+
+
+ o Unpack the bsd source code (if you haven't already)
+
+ If you're short on disk space (like me) just unpack:
+
+ sys, lib, share/mk, include, usr.sbin/config,
+ usr.sbin/dbsym, gnu/lib/libg++/g++-include,
+ usr.bin/lex
+
+ Otherwize, assuming you have a CD-DRIVE:
+
+ $ cd .../scratch
+ $ mkdir bsd-src
+ $ cd bsd-src
+ $ for d in /cdrom/bsdisc_12_95_disc2/NetBSD-1.1/source/*11
+ do
+ echo $d
+ cat $d/*.?? | gunzip | tar xf -
+ done
+
+ Flatten the directory structure a little.
+
+ $ mv usr/src/* .
+ $ rmdir usr/src usr
+ $ cd ..
- o Apply the remaining patches for the BSD source tree
+ o Apply the clayton (PowerPC) patches to your constructed
+ tree.
$ cd .../scratch
$ cd bsd-src
Diffs are applied using something like:
- $ gunzip < ../clayton-include-960203.diff.gz | more
- ...
+ $ gunzip < ../clayton-include-960312.diff.gz | patch -p1
+ $ gunzip < ../clayton-lib-960203.diff.gz | patch -p1
+ $ gunzip < ../clayton-sys-960203.diff.gz | patch -p1
The patch to sys/dev/pci/ncr.c.rej might fail.
to remove the `src' prefix. I used
$ ln -s . src
- $ gunzip < ../clayton-lib-960203.tar.gz | tar xtf -
- ...
+ $ gunzip < ../clayton-lib-960203.tar.gz | tar xvf -
+ $ gunzip < ../clayton-sys-960203.tar.gz | tar xvf -
So that src/xxx unpacked into ./xxx
-
$ cd ..
+ o install Berkeley make's include (mk) files.
+
+ $ cd .../scrath
+ $ cd bsd-src/share
+ $ tar cf - mk | ( cd /applications/psim/bsd-root/usr/share \
+ && tar xvf - )
+ $ cd ../..
+
o Install the include files
o Install a few other include files.
- As with building libnew, the bsd build process has
- several include file problems.
+ As discussed above in the section on building libnew,
+ the build process can have chicken/egg problems. In the
+ case of BSD's libc, it wants to use several include files
+ (from the installed include directory) before they are
+ installed. Just copy them in as seen below:
$ cd .../scratch
$ cd bsd-src
/applications/psim/powerpc-unknown-eabi/include
$ cp lib/libcurses/curses.h \
/applications/psim/powerpc-unknown-eabi/include
-
$ cd ..
+ o Unpack/patch/build/install BINUTILS
- o Build/install gcc
+ $ cd .../scratch
+ $ gunzip < binutils-2.6.tar.gz | tar xf -
+
+ gas (bfd) 2.6 didn't support the reading and writing of
+ note sections. The patch binutils-2.6+note.diff.gz
+ adds support for this. PowerPC/ELF boot files being loaded
+ by OpenBoot ROM's should contain a PowerPC note section.
$ cd .../scratch
- $ gunzip < gcc-2.7.2,tar.gz | tar xf -
+ $ cd binutils-2.6/bfd
+ $ gunzip < ../../binutils-2.6+note.diff.gz | more
+ $ gunzip < ../../binutils-2.6+note.diff.gz | patch
+ $ cd ../..
+
+ Then continue with the build
+
+ $ cd .../scratch
+ $ cd binutils-2.6
+ $ ./configure --target=powerpc-unknown-eabi \
+ --prefix=/applications/psim
+ $ make
+ $ make install
+ $ cd ..
+ $ rm -rf binutils-2.6
+
+ This has the intended side effect of partially populating
+ the psim directory tree which makes follow on steps easier.
+
+
+ o Unpack/patch/build/install GCC
+
+ $ cd .../scratch
+ $ gunzip < gcc-2.7.2.tar.gz | tar xf -
$ cd gcc-2.7.2
- GCC and BSD (for PowerPC) have a conflicting type
- declaration. The patch below gets around this
- problem:
+ GCC-2.7.2 and the BSD include files have a conflicting type
+ declaration. The patch below gets around this problem
+ (it may still be applicable to more recent versions of
+ GCC):
+ $ gunzip < ../gcc-2.7.2+sys-types.diff.gz | more
$ gunzip < ../gcc-2.7.2+sys-types.diff.gz | patch
+ If your version of GCC includes the file ginclude/ppc-asm.h
+ then you should install that header file into the directory:
+ /applications/psim/powerpc-unknown-eabi/include. More
+ recent versions of GCC expect this file to be installed:
+
+ $ test -r ginclude/ppc-asm.h \
+ && cp ginclude/ppc-asm.h \
+ /applications/psim/powerpc-unknown-eabi/include
+
Other than that, assuming the include files installed
okay, the rest should be fine ....
$ powerpc-unknown-eabi-make install
$ cd ../..
- If you encounter problems try the following: an include
- file not yet installed; a directory not yet created;
- running the hosts version of a program instead of a
- bsd version.
+ If you encounter problems check the following (each
+ discussed above):
+
+ o GCC and BSD have a common include
+ directory
+
+ o all the missing include files installed
+
+ o all the wrapper programs installed
+
o Build/run a simple BSD program
