Using crosstool-NG on FreeBSD (and other *BSD) |
-----------------------------------------------+
Contributed by: Titus von Boxberg
Prerequisites and instructions for using ct-ng for building a cross toolchain on FreeBSD as host.
0) Tested on FreeBSD 8.0
1) Install (at least) the following ports
archivers/lzma
textproc/gsed
devel/gmake
devel/patch
shells/bash
devel/bison
lang/gawk
devel/automake110
ftp/wget
Of course, you should have /usr/local/bin in your PATH.
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 as you like...]
3) proceed as described in general documentation
but use gmake instead of make
Using crosstool-NG on MacOS-X |
------------------------------+
Contributed by: Titus von Boxberg
Prerequisites and instructions for using crosstool-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) 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.
2) 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.
3) Install (at least) the following macports
ncurses
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
4) 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...]
5) proceed as described in standard documentation
-----
HINTS:
- Apparently, GNU make's builtin variable .LIBPATTERNS is misconfigured
under MacOS: It does not include lib%.dylib.
This affects build of (at least) gdb-7.1
Put 'lib%.a lib%.so lib%.dylib' as .LIBPATTERNS into your environment
before executing ct-ng build.
See http://www.gnu.org/software/make/manual/html_node/Libraries_002fSearch.html
as an explanation.
