Please see http://gnuradio.org for the wiki, bug tracking, and source code viewer. If you've got questions about GNU Radio, please subscribe to the discuss-gnuradio mailing list and post your questions there. http://gnuradio.org/redmine/projects/gnuradio/wiki/MailingLists There is also a "Build Guide" in the wiki that contains OS specific recommendations: http://gnuradio.org/redmine/projects/gnuradio/wiki/BuildGuide The bleeding edge code can be found in our git repository at http://gnuradio.org/git/gnuradio.git/. To checkout the latest, use this command: $ git clone git://gnuradio.org/gnuradio For information about using Git, please see: http://gnuradio.org/redmine/projects/gnuradio/wiki/DevelopingWithGit How to Build GNU Radio: (1) Ensure that you've satisfied the external dependencies listed below. The word "system" is used to mean "operating system and/or distribution", and means a full operating system, including kernel, user-space utilties, and a packaging system for additional software. On Linux, this means what "distribution" means. With the exception of SDCC, the following GNU/Linux distributions are known to come with all required dependencies pre-packaged: Ubuntu 8.10, SuSE 10.0 (the pay version, not the free download), Fedora Core 9. Other distribution may work too. We know these three are easy. The required packages may be contained on your installation CD/DVD, or may be loaded over the net. The specifics vary depending on your GNU/Linux distribution. On systems using pkgsrc (e.g. NetBSD and Dragonfly), build meta-packages/gnuradio, which will build a previous release and force installation of the dependencies. Then pkg_delete the gnuradio package, which will leave the dependencies. (This should also work on OSX.) See the wiki at http://gnuradio.org for details. (2) Building from cmake: $ mkdir $(builddir) $ cd $(builddir) $ cmake [OPTIONS] $(srcdir) $ make $ make test $ sudo make instal That's it! ------------------------------------------------------------------------------- KNOWN INCOMPATIBILITIES GNU Radio triggers bugs in g++ 3.3 for X86. DO NOT USE GCC 3.3 on the X86 platform. g++ 3.2, 3.4, and the 4.* series are known to work well. ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- External dependencies ------------------------------------------------------------------------------- Prerequisites: Before trying to build these from source, please try your system's installation tool (apt-get, pkg_install, YaST, yum, urpmi, etc.) first. Most recent systems have these packages available. You'll need to do a bit of sleuthing to figure out what your OS and packaging system calls these. If your system uses the convention of splitting files needed to run programs compiled with foo and files needed to do the compilation into packages named foo and foo-devel, install both packages. (Most GNU/Linux systems are like this, but pkgsrc is not and instead uses -devel to indicate a package of a not-yet-released or unstable version.) For those using pkgsrc, see gnuradio-pkg_chk.conf. Those not using pkgsrc may also find the list useful. (0) GNU make It used to be required to have a "reasonable make", meaning GNU make, BSD make, or perhaps Solaris make. It is now required to use GNU make. Version 3.81 should certainly work; the intent is not to require the bleeding edge. Note that the examples below are written with "make". They probably should say "gmake", as GNU make is installed as gmake when it is not the native make. (1) The "autotools" autoconf 2.57 or later automake 1.7.4 or later libtool 1.5 or later If your system has automake-1.4, there's a good chance it also has automake-1.7 or later. Check your install disk and/or (on GNU/Linux) try: $ man update-alternatives for info on how some distributions support multiple versions. (2) pkgconfig 0.15.0 or later http://www.freedesktop.org/Software/pkgconfig From the web site: pkgconfig is a system for managing library compile/link flags that works with automake and autoconf. It replaces the ubiquitous *-config scripts you may have seen with a single tool. (3) FFTW 3.0 or later http://www.fftw.org IMPORTANT!!! When building FFTW, you MUST use the --enable-single and --enable-shared configure options. This builds the single precision floating point version which we use. You should also use either the --enable-3dnow or --enable-sse options if you're on an Athlon or Pentium respectively. GNU/Linux packages of single-precision fftw are typically called fftw3f. In systems using pkgsrc, install math/fftwf, which provides the single-precision libraries. (4) Python 2.5 or later http://www.python.org Python 2.5 or later is now required. If your system splits python into a bunch of separate packages including python-devel or libpython you'll most likely need those too. (5) Numpy python library http://numeric.scipy.org Provides a high performance array type for Python. http://numpy.scipy.org http://sourceforge.net/project/showfiles.php?group_id=1369&package_id=175103 (6) The Boost C++ Libraries (1.35 or later) http://www.boost.org We use Smart Pointers, the thread library and a bunch of other boost stuff. If your system doesn't have boost 1.35 or later, see README.building-boost for additional info. (Note: Mac OSX systems require 1.37 or later.) (7) cppunit 1.9.14 or later. http://cppunit.sourceforge.net Unit testing framework for C++. (8) Simple Wrapper Interface Generator. http://www.swig.org As of repository version 4045, gnuradio requires version 1.3.31 or newer. (9) SDCC: Small Device C Compiler. http://sdcc.sourceforge.net/ --> Not required as of v3.5 (10) Guile 1.6 or 1.8 Scheme interpreter. http://www.gnu.org/software/guile/guile.html (11) GNU Scientific Library (gsl) 1.10 or later The GNU Radio core library uses some routines from here. Optional, but nice to have: (12) wxPython. Python binding for the wxWidgets GUI framework. Use version 2.8 or later. Again, almost all systems have this available. As a last resort, build it from source (not recommended!) http://www.wxpython.org (13) xmlto version ? or later. http://cyberelk.net/tim/xmlto/index.html Wrapper for XML conversion tools to ease e.g. making html from docbook. (14) Python Cheetah extensions 2.0.0 or later (15) Python lxml wrappers 2.0.0 or later (16) Python gtk wrappers 2.10.0 or later The GNU Radio Companion application requires these additional Python libraries to be installed. ---------------------------------------------------------------- If you've got doxygen installed, the build process creates documentation for the class hierarchy etc. Point your browser at gnuradio/gnuradio-core/doc/html/index.html To run the examples you may need to set PYTHONPATH. Note that the prefix and python version number in the path needs to match your installed version of python. $ export PYTHONPATH=/usr/local/lib/python2.5/site-packages You may want to add this to your shell init file (~/.bash_profile if you use bash). Another handy trick if for example your fftw includes and libs are installed in, say ~/local/include and ~/local/lib, instead of /usr/local is this: $ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/local/lib $ make CPPFLAGS="-I$HOME/local/include" Sometimes the prerequisites are installed in a location which is not included in the default compiler and linker search paths. This happens with pkgsrc and NetBSD. To build, tell configure to use these locations: LDFLAGS="-L/usr/pkg/lib -R/usr/pkg/lib" CPPFLAGS="-I/usr/pkg/include" ./configure --prefix=/usr/gnuradio ------------------------------------------------------------------------------- Legal Matters ------------------------------------------------------------------------------- Some files have been changed many times throughout the years. Copyright notices at the tops of these files list which years changes have been made. For some files, changes have occurred in many consecutive years. These files may often have the format of a year range (e.g., "2006 - 2011"), which indicates that these files have had copyrightable changes made during each year in the range, inclusive.
