We are talking about the linux distros the developers are using. If someday, the popular distros, like Ubuntu/Fedora/openSUSUE, start to release arm/x32 versions, surely the tools will support it. > > if the problem is qemu on 32bit x86 emulating arm... mayhaps we should talk > about that issue itself? i remember there being memory mapping > conflicts/issues > in doing misc binary emul, but i don't remember the details anymore. Besides qemu's issue, and there are some build issues for baselibs, as I remember. And it's already half a year it cannot be resolved. It's tricky but we have workaround solution already, but it will also affect the tools quality. thanks - jf.ding > > > Hi, Auke > > > > The major reason of 32bit-linux-platform tools support dropping plan is the > > qemu issue: we still have no stable 32bit qemu-static executable for current > > Tizen, which is very important for the local build and image creation in > > 32bit > > development systems. > > > > And the future 64bit support of Tizen itself is only the last straw of it. > > Whenever the 64bit Tizen development is the necessary part of developers' > > work, they can only use 64bit development environment. > > > > thanks > > - jf.ding > > > > On Wed, Sep 18, 2013 at 12:47:54PM -0700, Kok, Auke-jan H wrote: > > > On Wed, Sep 18, 2013 at 12:21 PM, Tomasz Olszak <[email protected]> > > > wrote: > > > > > > > > I'm opposed to this. > > > >> > > > >> > > > >> 64bit support in Tizen is not yet mainstream at all, as a matter of > > > >> fact it's barely been implemented in 3.0, and no major release that > > > >> developers can use yet has happened. > > > >> > > > >> Can we maintain 32bit code until most developers have had a major > > > >> release on 64bit?
