Hello,
I read the article "Building toolchain with crosstool-ng on Mac OS X SL" in the mail archive and I am not sure which version of coreutils, gawk, libtool and so on I need. I read the MacOS-X.txt, too.
I started with the command of the MacOS-X.txt manually and I got a lot of warnings and errors:
--------------------------------------------------------------------------

Hello Uwe, all
I recently made a patch for using crosstool-ng on mac and freebsd.
I will rework the cosmetics according to Yann's comments this month.
If you need it upfront, I can send it over.
Regards
Titus

Titus, I think you are the one that can handle this stuff, as you have a
MacOS-X at hands, and you have already handled the most difficult part.
I'd be really happy to look at your new patchset.
BTW, please next time also CC the list for your updated patchset.
Regards,
Yann E. MORIN.

This patch is still very large, and contains unrelated changes.
It is thus hard to see the implications of each change.
Please, split the patch into self-contained patches that each add a
single change, as I suggested ealier. For example:
- the sed->$(sed) change in samples.mk on its own
- the configure+Makefile.in changes into their own (one for libtool, one
for objcopy, ...)
- one for Darwin/*BSD vs. GNU
- and so on...
Having each change in a separate patch will help with review. Small patches
(few-liners) will most probably pass in a blink of an eye. When they get
applied, they will each yield a new changeset in the tree, and that would
be easier to revert the one(s) that is(are) faulty without having to revert
the whole stuff.
Also, if you would provide mercurial patches, it would be easier to work
with. See docs/overview.txt, section "Contributing".

Good. :-)

One patch per new tool, please. Also, be sure to see how it plays with
the companion tools that were recently added.

One patch for that.

"readlink -e" and "readlink" are not equivalent.

Separate patch for that.

Ditto.

On my system (%Q is not recognised, so use that)

%Q
So this change seems to imply that on MacOS-X or *BSD, we get:

N
Right?

Separate patch for that as well.

Not reliable on my system:
> config.guess
x86_64-unknown-linux-gnu
> gcc -dumpmachine
x86_64-linux-gnu
And I have the tools for x86_64-linux-gnu-{gcc,ld,...}, but not the ones for
x86_64-unknown-linux-gnu-{gcc,ld,...}. So it is much more reliable to ask
gcc than to ask config.guess.
gcc -dumpmachine will tell us the tuple for which it was configured, and
that means the prefix to use to the actual tools, which is what we need.

Statically linking should hopefully speed up things. Having a /slow/
wrapper is not very interesting, is it? Of course, the ratio
time-in-wrapper / (time-in-wrapper + time-in-actual-tool) should be
fairly small, except for very trivial programs, where the total time
will anyway be almost imperceptible...

Separate patch.

Please, provide a split-up patchset as instructed above, and we'll be
able to easily review it.
Thank you! :-)

Uwe, Yann, all
here is the reworked patch for crosstool-ng on FreeBSD and MacOS against a current (31 January 23:00 CET) version.
And two new READMEs (instead of docs/MacOS-X.txt).
Almost all patch parts revolve around GNU/BSD incompatibilities.
I try to explain what I did:
- enlarge the list of configurable tools that ctng uses (for usage of GNU tools).
- also make sure that the configured tools actually get used.
- make all calls to stat(1) dependent to `uname -s` or replace the call.
- replace all calls to readlink(1GNU) with compatible variants.
This makes the usage of wrapper.c mandatory on MacOS because there is no way known to me emulating readlink -m without a lengthy shell script.
- uname -o is not portable. use -s when -o fails
- a bug in the sed-expression that sets the nanoseconds to 0 for a date(1) not handling %N
Notable other reasons besides GNU/BSD are:
- have to compile mpfr with --disable-thread-safe on darwin.
- "You did not specify the build system. That's OK, I can guess...":
Under MacOS 10.6 gcc reports itself as "i686-apple-..."
However, it's default behaviour is to generate 64bit objects.
This clashes with some configure scripts that require "x86_64-..." for configuring for a 64bit host.
Using CT_DoConfigGuess does the job correctly.
Why not use that in general?
BTW, the above two changes are the only changes actually for BUILDING the toolchain, and not for porting ctng itself.
- the compiler command line options for compiling wrapper.c crashes gcc on MacOS (and IMHO were a little bit overdone for the complexity of wrapper.c).
- you should not link statically on MacOS (wrapper.c command line again)
- under Darwin, use DYLD_LIBRARY_PATH in wrapper.c
- added printenv to the build.log (I found that helpful).
I can now compile gcc4.4.2 for powerpc for linux/glibc under Linux, BSD, and MacOS.
I only shortly grepped through scripts not necessary for this configuration, so more incompatibilities may arise. However, they should be easy to fix in this manner.
Hope this helps.
Further comments are welcome.
Regards
Titus

General instructions for using ct-ng for building a cross toolchain on FreeBSD as host.
1) Install (at least) the following ports
archivers/lzma
textproc/gsed
devel/gmake
devel/patch
shells/bash
devel/bison
2) run ct-ng's configure with the following tool configuration:
./configure --with-sed=/usr/local/bin/gsed --with-make=/usr/local/bin/gmake \
--with-patch=/usr/local/bin/gpatch
[...other configure parameters...]
3) proceed as described in general documentation

*General* instructions for using ct-ng for building a cross toolchain on MacOS as host.
0) Mac OS Snow Leopard, with Developer Tools 3.2 installed, or
Mac OS Leopard, with Developer Tools & newer gcc (>= 4.3) installed via macports
1) Install macports (or similar easy means of installing 3rd party software),
make sure that macport's bin dir is in your PATH. Furtheron assuming it is /opt/local/bin.
2) Install the following macports
lzmautils
libtool
binutils
gsed
gawk
gcc43 (only necessary for Leopard OSX 10.5)
On Leopard, make sure that the macport's gcc is called with the default commands
(gcc, g++,...), e.g. via macport gcc_select
3) run ct-ng's configure with the following tool configuration
(assuming you have installed the tools via macports in /opt/local):
./configure --with-sed=/opt/local/bin/gsed --with-libtool=/opt/local/bin/glibtool \
--with-objcopy=/opt/local/bin/gobjcopy --with-objdump=/opt/local/bin/gobjdump \
--with-readelf=/opt/local/bin/greadelf [...other configure parameters as you like...]
4) You have to use a case sensitive file system for ct-ng's build and target directories.
Use a disk or disk image with a case sensitive fs that you mount somewhere.
5) proceed as described in standard documentation
