This is the GNU cflow package. This document describes the actions needed to build the pre-release or CVS version of the package. See end of file for copying conditions. * Introduction This is a *pre-release* version, and not ready for production use yet. If you are taking source from CVS, you will need to have automake, and autoconf installed to bootstrap the package. See the chapter `Building' for the detailed instructions. After bootstrapping, there should be a file 'INSTALL' with generic installation instructions. Package-specific installation instructions are set forth in the file README. Please, note that the accompanying documentation may be inaccurate or incomplete (well, to say the truth it is absent. See TODO for more info). The ChangeLog file is the authoritative documentation of all recent changes. Report bugs to * Checking Out the Sources The following instructions apply if you wish to obtain sources from the CVS repository: To checkout the source tree from CVS issue the following command: CVS_RSH=ssh \ cvs -d :ext:anoncvs@savannah.gnu.org:/cvsroot/cflow checkout cflow Make sure SSHv2 is used. This will give you read-only access. If you think you need write access, contact the mailing list. The CVS repository is also available via HTTP from http://savannah.gnu.org/cgi-bin/viewcvs/cflow/cflow/ * Building In order to build this you will first need to have right versions of autotools. At the time of this writing these are: Package Version (>=) ======== ============ automake 1.8.5 autoconf 2.59 To prepare the package for building run build-aux/bootstrap. For example: $ cd cflow $ build-aux/bootstrap If you have already checked out gnulib sources, use --gnulib-srcdir to specify their location, this will spare you time and bandwidth: $ cd cflow $ build-aux/bootstrap --gnulib-srcdir=$HOME/gnu/gnulib * Debugging To enable additional debugging information, configure the package with --enable-debug option. Sometimes it is impossible or inconvenient to start cflow from the debugger. In this case, use --HANG option. The option instructs the program to sleep for a given number of seconds (3600 by default) right after startup. For example, run: cflow --HANG [OTHER-OPTIONS] Then switch to another terminal, get the PID of the ivoked utility and attach to it using gdb: gdb cflow PID Once in gdb, issue the following command set _argp_hang=0 Now set your breakpoints and proceed as usual. * Copyright information: Copyright (C) 2005 Sergey Poznyakoff Permission is granted to anyone to make or distribute verbatim copies of this document as received, in any medium, provided that the copyright notice and this permission notice are preserved, thus giving the recipient permission to redistribute in turn.
