More specifically, it does not create a toolchain for arm. The toolchain runs on x86_64 called 'dotnet' creates arm binaries and C# managed dlls. > > > Best regards. > > Jiyoung Yun. > > > > > > --------- Original Message --------- > > Sender : > > 하이츨러 <c.haitz...@samsung.com> Master/S/W Platform팀(S/W센터)/ > > 삼성전자 Date : 2016-12-08 18:28 (GMT+9) > > Title : Re: [Dev] Fix host architecture to x86_64 for building arm target > > On Thu, 08 Dec 2016 18:11:46 +0900 > > ____ <chan45....@samsung.com> wrote: > > > > > Dear Tizen developers, > > > > > > Currently we are using two host environments, as you know, i586 and > > > x86_64.
