Operating a computer while driving is extremely dangerous. If using Roadnav in a car, always have a passenger operate Roadnav. Drivers should always keep their eyes on the road.
The data provided by the US Census Bureau is largely accurate, but it is known to contain bugs. Use at your own risk.
The current stable version of Roadnav is 0.19.
Precompiled Packages (Stable)
Various precompiled/prepackaged versions of Roadnav are available:
Compiling From Source (Stable)
If you do not see your platform listed, the Roadnav source code can be downloaded from Sourceforge. LibRoadnav source code can be downloaded from here. Installation is simply a matter of unpacking the LibRoadnav archive somewhere (e.g. /usr/local/src), and doing a "./configure ; make", then "make install" as the superuser, and repeating this process for Roadnav.
If you do not have a Speech icon in control panel, you may also want to download and install the Microsoft SAPI 5.1 SDK so you can get verbal turn by turn directions.
Linux/OS X Notes
Roadnav can also use the Festival Speech Synthesis System if it is installed. Consult your distribution for precompiled Festival packages.
If you are using a Roadnav package precompiled for a Linux distribution that does not exactly match the distribution you are running, and you are experiencing unusual crashes, especially crashes whenever you click on the map, it is recommended that you recompile Roadnav from its source. Newer distributions (e.g. Fedora 8) are not compatible with the precompiled packages here, but should work fine if you compile Roadnav from source.
Experimental releases can be downloaded from below. They have not been tested as much as the stable releases and probably contain bugs. If you encounter any bugs in the experimental releases, please report them on the Sourceforge tracker system so they can get resolved before they end up in a stable version. The change log has a complete list of changes in the experimental release.
