Carsten, All the embarrassings you are talking about just does not exist :)
Current Tizen pkg build is self-hosted, both ARM and IA, both 32bit and 64bit. Current problem we are talking about is the developers' working distro, not the Tizen runtime:) thanks - jf.ding On Mon, Sep 23, 2013 at 06:23:37PM +0900, Carsten Haitzler wrote: > On Mon, 23 Sep 2013 08:28:06 +0300 Leon Anavi <[email protected]> said: > > > Hi Daniel, Carsten, All, > > > > On 2013-09-23 03:46, Daniel Juyung Seo wrote: > > > On Mon, Sep 23, 2013 at 8:53 AM, Carsten Haitzler > > >> imagine if all the engineers and executives etc. at bmw drove fords > > >> because > > >> "bmw's can't manage to get us to the office without breaking down". > > > > > > Awesome analogy. > > > > > > I am also against dropping 32 bit system support for dev tools. > > > > > > I bet many people I know use 32 bit system yet. > > > > > > > The example with the cars is nice but I don't think it's very > > appropriate.
