clang packaging for debian

[Andreas Fink]

Hello

I'm having issues with clang packages for debian stretch. I'm trying to compile gnustep and always run into compilation/linking issues. Accoding to David Chisnal they have been recently fixed in clang, however I can not seem to find any package which works. Neither clang-7 nor clang-8 are able to successful compile libobjc2 and gnustep-base.

Is it possible that I'm not getting the latest version from the repo or I'm looking at the wrong location?


I have  this in my Apt sources


deb http://apt.llvm.org/stretch/ llvm-toolchain-stretch main
deb-src http://apt.llvm.org/stretch/ llvm-toolchain-stretch main
# 7
deb http://apt.llvm.org/stretch/ llvm-toolchain-stretch-7 main
deb-src http://apt.llvm.org/stretch/ llvm-toolchain-stretch-7 main
# 8
deb http://apt.llvm.org/stretch/ llvm-toolchain-stretch-8 main
deb-src http://apt.llvm.org/stretch/ llvm-toolchain-stretch-8 main


and I have installed clang-7  or clang-8 and call the tools like this.

Compiling libobjc2 seems to work but when configuring gnustep-base, it barks saying I have an old runtime which doesnt support tons of things which clang all should ahve

one of them is

config/config.non-fragile-ivars.m

which tests

	return __has_feature(objc_nonfragile_abi) ? 0 : 1;


which apparently returns 0. while I'm pretty sure this should be 1.

Also it claims there's no support for synchronisation or properties and the like.


I'm trying to get a recent version compiled since 3 weeks and seem not to have any combination of compiler/libraries/runtimes getting to work.

So any hint is welcome...
