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.
