This file describes how to build from CVS sources. If you are building from a
released version or snapshot, please refer to the 'INSTALL' document instead.
-------------
Prerequisites
-------------
You will need the following tools to obtain and build a CVS version of pcb:
To download and track sources you will need:
cvs
ssh
To compile you will need a C compiler, a lex (or flex) and a yacc (or bison)
implementation. If you do not have lex or yacc, try installing:
bison -- ftp://ftp.gnu.org/pub/gnu/bison/
flex -- ftp://ftp.gnu.org/pub/non-gnu/flex/
In addition, if you make any edits to configure.ac or any of the
Makefile.am's, you will need recent versions of:
autoconf -- ftp://ftp.gnu.org/pub/gnu/autoconf/
Please note that version 2.13 is too old.
automake -- ftp://ftp.gnu.org/pub/gnu/automake/
texinfo -- ftp://ftp.gnu.org/pub/gnu/texinfo/
You can find the version of autoconf and automake by running them with the
--version flag.
Finally, if you edit any of the actions identified by
/* ACTION(Foo,ActionFoo) */
comments, you will need perl and in addition, you must have used
the --enable-maintainer-mode flag to the configure script.
---------
Check out
---------
If you already have a checked PCB source tree, please proceed to the
'Updating' section.
To check out sources from the anonymous CVS server, run the following:
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/pcb login
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/pcb co pcb
---------
Updating
---------
To update an already checked out copy of the PCB source tree, run these commands
from your top level pcb directory:
cvs login
cvs -z3 update -PdA
----------------------------------
Bootstrapping with the auto* tools
----------------------------------
If you have made any edits to configure.ac in the top level pcb directory
or any of the Makefile.am's, you will need to run
./autogen.sh
from the top level pcb directory. This will run the various auto* tools
which creates the configure script, the config.h.in file and the various
Makefile.in's.
If you have not edited configure.ac or Makefile.am's, you can skip this
step.
If you plan on making changes to configure.ac, Makefile.am's, or actions
defined by the
/* ACTION(Foo,ActionFoo) */
comments, you may want to enable maintainer mode by passing the
--enable-maintainer mode flag to ./autogen.sh
At this point you can proceed to configure and build PCB as outlined in
the INSTALL document.
