Hi I'm having trouble even getting a native Ada toolset built from gcc 7.4.0. I can build gcc with Ada from the gcc master but gcc 7.4.0 says I don't have proper tools and disables building Ada. Admittedly, I am on Cent)S 7 which has an ancient gcc 4.8 native toolset but I don't see why I can build one but not the other.
And the Ada in GCC's master is apparently stricter than gcc 7.4.0 was. I have a patch to fix a fair number of with/use warnings in gnat 7.4.0 so it will compile with the gcc master. Any hints on how any of you are getting a matching native Ada compiler to make this work? --joel On Mon, Dec 3, 2018 at 12:19 AM Sebastian Huber < sebastian.hu...@embedded-brains.de> wrote: > On 02/12/2018 23:36, Chris Johns wrote: > > On 30/11/2018 19:01, Sebastian Huber wrote: > >> I regularly build the RTEMS 5 tools with Ada support using the RSB, e.g. > >> > >> cd $RSB/rtems > >> ../source-builder/sb-set-builder --prefix=/opt/rtems/5 5/rtems-sparc > --with-ada > >> > > Great.
