OK, I now got a clang7 build running on a machine here too. Simon, if you are listening: The alternative instructions to installing SDK to /usr/include seems to be incomplete. With
CPPFLAGS="-isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include" I got a succesful compile, but the link phase dies looking for -lSystem or somesuch. I.e., I think something needs to happen with LDFLAGS as well. This of course only shows up if you do not install the SDK to /usr/include. -pd > On 19 Aug 2019, at 11:54 , Göran Broström <goran.brost...@umu.se> wrote: > > Here is the report I promised.
