 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 developers 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:

   mkdir work-dir

   cd work-dir

   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. First, you need to generate the ./configure script from its autoconf

 template:

   ./bootstrap

 Then, you run ./configure for local execution of crosstool-NG:

   ./configure --enable-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 changes.

 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 contributed 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 particular contribution applies to the current

 version of crosstool-ng, or that it will work at all. Use contributions at

 your own risk.
