Installing crosstool-NG /
|
||
|
|
________________________/
|
||
|
|
|
||
|
|
|
||
|
|
There are two ways you can use crosstool-NG:
|
||
|
|
- build and install it, then get rid of the sources like you'd do for most
|
||
|
|
programs,
|
||
|
|
- or only build it and run from the source directory.
|
||
|
|
|
||
|
|
The former should be used if you got crosstool-NG from a packaged tarball, see
|
||
|
|
"Install method", below, while the latter is most useful for developpers that
|
||
|
|
use a clone of the repository, and want to submit patches, see "The Hacker's
|
||
|
|
way", below.
|
||
|
|
|
||
|
|
|
||
|
|
Install method |
|
||
|
|
---------------+
|
||
|
|
|
||
|
|
If you go for the install, then you just follow the classical, but yet easy
|
||
|
|
./configure way:
|
||
|
|
./configure --prefix=/some/place
|
||
|
|
make
|
||
|
|
make install
|
||
|
|
export PATH="${PATH}:/some/place/bin"
|
||
|
|
|
||
|
|
You can then get rid of crosstool-NG source. Next create a directory to serve
|
||
|
|
as a working place, cd in there and run:
|
||
|
|
ct-ng help
|
||
|
|
|
||
|
|
See below for complete usage.
|
||
|
|
|
||
|
|
|
||
|
|
The Hacker's way |
|
||
|
|
-----------------+
|
||
|
|
|
||
|
|
If you go the hacker's way, then the usage is a bit different, although very
|
||
|
|
simple:
|
||
|
|
./configure --local
|
||
|
|
make
|
||
|
|
|
||
|
|
Now, *do not* remove crosstool-NG sources. They are needed to run crosstool-NG!
|
||
|
|
Stay in the directory holding the sources, and run:
|
||
|
|
./ct-ng help
|
||
|
|
|
||
|
|
See below for complete usage.
|
||
|
|
|
||
|
|
Now, provided you used a clone of the repository, you can send me your changes.
|
||
|
|
See the section titled CONTRIBUTING, below, for how to submit changees.
|
||
|
|
|
||
|
|
|
||
|
|
Preparing for packaging |
|
||
|
|
------------------------+
|
||
|
|
|
||
|
|
If you plan on packaging crosstool-NG, you surely don't want to install it
|
||
|
|
in your root file system. The install procedure of crosstool-NG honors the
|
||
|
|
DESTDIR variable:
|
||
|
|
|
||
|
|
./configure --prefix=/usr
|
||
|
|
make
|
||
|
|
make DESTDIR=/packaging/place install
|
||
|
|
|
||
|
|
|
||
|
|
Shell completion |
|
||
|
|
-----------------+
|
||
|
|
|
||
|
|
crosstool-NG comes with a shell script fragment that defines bash-compatible
|
||
|
|
completion. That shell fragment is currently not installed automatically, but
|
||
|
|
this is planned.
|
||
|
|
|
||
|
|
To install the shell script fragment, you have two options:
|
||
|
|
- install system-wide, most probably by copying ct-ng.comp into
|
||
|
|
/etc/bash_completion.d/
|
||
|
|
- install for a single user, by copying ct-ng.comp into ${HOME}/ and
|
||
|
|
sourcing this file from your ${HOME}/.bashrc
|
||
|
|
|
||
|
|
|
||
|
|
Contributed code |
|
||
|
|
-----------------+
|
||
|
|
|
||
|
|
Some people contibuted code that couldn't get merged for various reasons. This
|
||
|
|
code is available as lzma-compressed patches, in the contrib/ sub-directory.
|
||
|
|
These patches are to be applied to the source of crosstool-NG, prior to
|
||
|
|
installing, using something like the following:
|
||
|
|
lzcat contrib/foobar.patch.lzma |patch -p1
|
||
|
|
|
||
|
|
There is no guarantee that a particuliar contribution applies to the current
|
||
|
|
version of crosstool-ng, or that it will work at all. Use contributions at
|
||
|
|
your own risk.
