gpsd 2.94 was already in openwrt, however getting gpsd 3.x to work required scons cross-support.
dealing with the scons support problem requires a patch to openwrt at present that may need some further work. The openwrt specific patch for scons support is at: http://huchra.bufferbloat.net/~cero1/gpsd-patches/ A revised gpsd package, using gpsd from nearly-git-head (which also contains changes to support cross compilation in general), is presently available as part of the ceropackages git repository: https://github.com/dtaht/ceropackages (this repo has been where we've been spinning up new packages like pimd, ccnx, etc, which openwrt users can add to their feeds.conf: git://github.com/dtaht/ceropackages.git ) After gpsd stablizes (gpsd 3.2?) we can get it into openwrt head, but in the meantime it would be good to know if gpsd 3.x worked well on other variants of openwrt. I note that you will have to install the right kmod-serial-* to get the right kernel support for your specific device, and enabling the -G option to gpsd allows you to contact the router remotely with tools like cgpsd, etc. On Sat, Sep 17, 2011 at 6:33 AM, Eric Raymond <[email protected]> wrote: > This is a heads-up for those of you looking into gpsd cross-build for > embedded deployments. > > I've been cooperating with Dave Taht and the Bufferbloat project (see > http://www.bufferbloat.net/).
