Re: GNUstep runtime errors

[Andreas Fink]

I see you are trying on Debian 12.

Things to remember on Debian if you use llvm and ARC.

1. you must use the new runtime libobjc2

2. always use the gold linker and not the default "ld.bfd" linker or you will end up compiling but not working

easiest way to change this is by changing the symlink /usr/bin/ld to point to ld.gold (which is a symlink to x86_64-linux-gnu-ld.gold)

3. Choose carefully which clang version you use.  Prior to release 8 there where issues. On Debian 11 there where issues with too new versions. On Debian 12, the standard clang 14.0.6 works fine for me.

 

here is how I build on Debian 12 and it works consistently.

Note: I do not use the old runtime or gcc ever for GNUStep as my code all mandatory requires ARC. So libobjc2 and clang/llvm is the only way which I can get anything done.

I wasted almost a week in this problem, all kinds of methods have been tried or not solved, I hope to get your help! I've already referred to "https://github.com/gnustep/libobjc2/issues/196" and "https://github.com/gnustep/libobjc2", but I still don't understand what the problem is. But I still don't understand where the problem is? How can I solve it? I have even recompiled GNUstep, libobjc2 with the latest clang, but the problem still exists. As long as -fobjc-runtime is set to gnustep-2.0 it will not compile, it can only be set to 1.9. Can you tell me how to solve this problem? What is the nature of this problem? 

Forgive me, I am really powerless to seek your help, google I only found a piece of information about this problem is the above mentioned link, I also asked the GPT but the answer is not the answer!

Thanks! 

Best regards!
