......@@ -9,13 +9,23 @@ Default location for configuration file is /usr/local/etc/bird.conf and
for control socket is /usr/local/var/run/bird.ctl . You can change that
by --sysconfdir and --localstatedir configure options.
To compile current development BIRD source code from Git repository, you
also need Git (to download the source code) and Autoconf (to generate
the configure script and associated files using 'autoreconf' tool):
$ git clone git://git.nic.cz/bird.git
$ cd bird
$ autoreconf
Then continue as in usual installation above.
Requirements
============
For compiling BIRD you need these programs and libraries:
- GNU C Compiler
- GNU C Compiler (or LLVM Clang)
- GNU Make
- GNU Bison
- GNU M4
