Someone contacted me because he would like to use Navit in German on a TomTom One 3rd Edition. Unfortunately the binary package that I currently provide does not have multilingual support (see below), and I can't do any software development for TomTom as the moment because I don't have TomTom device at hand. So maybe someone could help with the following tasks? The main point is testing the software on a TomTom - I have the compiler at hand, so I can compile the files and provide some binaries, but I cannot test or debug them.

  • Navit uses gettext for translations. Natively there is no gettext library on TomTom Linux, so it needs to be compiled from source and installed on the TomTom. See http://www.gnu.org/software/gettext/.
  • On the TomTom currently festival-lite is used for speech output, but it supports only American English. It would be much better to use espeak, but I could not get it to run so far. In fact, it is already integrated into the Navit source, so it would be best to use this integrated version, but also a stand-alone version would be helpful. See http://espeak.sourceforge.net/.

For general information on developing for TomTom, getting the toolchain and porting Navit, see:

Hi!
Iirc, navit espeak module highly depends on windows infrastructure to play wav files it produces. So probably compiling standalone espeak on tomtom might be simplier option.

Also, festival lite iirc is multilingual, so best option would be to try it first.

As for gettext, we use our own copy of it on windows. It might work if we try to enable using it for tomtom build. See under support/gettext_intl. btw, how did you work around need for gettext in your builds?

Ah, I see. I'll give it a try.

Indeed, it should be, according to the website it comes with loadable voices. Unfortunately so far I could find only US American and Indian voices, which I would rather call "oligolingual" than multilingual.

Apparently there was no need for it when compiling for the TomTom platform... It even shows that it has found gettext - in fact, it found gettext binaries on the build computer, and falsely concluded that there is gettext support on the host as well. But indeed, I wonder whether this does not lead to compile / link errors. Are there any dummy functions provided as a failsafe option?

In the meantime I figured out that TomTom's glibc version comes with gettext support. I compiled a binary package which could provide some multilingual display text now - even though speech output will still use the American voice. However, this is untested, as I have no way of testing it at the moment, so anyone who is willing to try feel free to test it:

I tried the files, but a actual updated tomtom one XL freeze at the start screen after ttsystem is booted.
Removing navit files don't help. New TT installation is needed.

Keep your TT-maps save. All other files come from TT-server.
