Hi,
On the latest develop with the latest macOS Sierra and homebrew, If I
have a target:
targets/slim_slinky
app=apps/slinky
bsp=hw/bsp/native
build_profile=debug
(used to be optimized :-)
And I try and build:
$ newt run slim_slinky
Error: In file included from
/usr/local/Cellar/gcc5/5.4.0/lib/gcc/5/gcc/x86_64-apple-darwin15.0.0/5.4.0/include-fixed/syslimits.h:7:0,
from
/usr/local/Cellar/gcc5/5.4.0/lib/gcc/5/gcc/x86_64-apple-darwin15.0.0/5.4.0/include-fixed/limits.h:34,

/usr/local/Cellar/gcc5/5.4.0/lib/gcc/5/gcc/x86_64-apple-darwin15.0.0/5.4.0/include-fixed/limits.h:168:61:
error: no include path in which to search for limits.h
I get beyond this by compiling out gcc-5, and instead using the native
Mac LLVM compiler (fixes in dev to make the system work with that).
However, the next issue is gdb:
$ newt run slim_slinky

If I switch to using llvm debugger, I can debug the system. Which is
fine, but I do generally prefer gdb due to familiarity. Still, for
those searching for a quick solution, lldb is fine.
Has anyone had success making these work on the latest macOS sierra. My
