As of August 3, 2006 we have restructured the GNU Radio build process and moved the source code repository from CVS to subversion. Please see http://gnuradio.utah.edu/trac for the wiki, bug tracking, and source code viewer. The bleeding edge code can be found in our subversion repository at http://gnuradio.utah.edu/svn. To checkout the latest, use this command: $ svn co http://gnuradio.utah.edu/svn/gnuradio/trunk gnuradio For information about subversion, please see: http://subversion.tigris.org/ GNU Radio is now distributed as one giant blob, instead of N smaller blobs. We believe that this will reduce some of the build problems people were seeing. Now you'll always get all of the code, and the configure step will determine which components can be built on your system. How to Build GNU Radio: (1) Ensure that you've satisfied the external dependencies listed below. With the exception of SDCC, the following GNU/Linux distributions are known to come with all required dependencies pre-packaged: Ubuntu 6.06, SuSE 10.0 (the pay version, not the free download), Fedora Core 5. 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. See the wiki at http://gnuradio.utah.edu/trac/wiki for details. FIXME: update the wiki; talk about OS/X, NetBSD and MinGW too. (2) do the "usual dance" $ ./bootstrap # not reqd when building from the tarball $ ./configure $ make && make check $ sudo make install 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 installation tool (apt-get, YaST, yum, urpmi, etc.) first. Contemporary distributions 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 has both a foo and a foo-devel package, install them both. (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 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. (4) Python 2.3 or later http://www.python.org Python 2.3 or later is now required. If your distribution splits python into a bunch of separate RPMS including python-devel or libpython you'll most likely need those too. (5) Numeric python library http://numeric.scipy.org Provides a high performance array type for Python. http://sourceforge.net/project/showfiles.php?group_id=1369&package_id=1351 (6) The Boost C++ Libraries http://www.boost.org We use the Smart Pointer library. Your distribution almost certainly has the boost libraries available. In the unlikely event that it doesn't, download the source and follow the build instructions. They're different from the normal ./configure && make (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 These versions are known to work: 1.3.23, 1.3.24, 1.3.25, 1.3.27, 1.3.28, 1.3.29 (9) SDCC: Small Device C Compiler. http://sdcc.sourceforge.net/ Use version 2.4.0 or later. This includes a C compiler and linker for the 8051. It's required to build the firmware for the USRP. If you don't have a USRP, don't worry about it. Optional, but nice to have: (10) wxPython. Python binding for the wxWidgets GUI framework. Use version 2.5.2.7 or later. Again, your distribution almost certainly has this available. As a last resort, build it from source (not recommended!) http://www.wxpython.org ---------------------------------------------------------------- If you've got doxygen installed and provide the --enable-doxygen configure option, 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'll need to set PYTHONPATH. Note that the python version number in the path needs to match your installed version of python. $ export PYTHONPATH=/usr/local/lib/python2.3/site-packages You may want to add this to your ~/.bash_profile 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"
