Hello, guys.
I tried to build HelloWorld with dub, but i got strange linker error:

On previously versions of Ubuntu all work fine.

What is the problem? Does anybody have any idea?

I just switched from Windows to linux (arch) and got the exact same problem. Did you resolve this yet? I'm not very experienced with development on linux any hint here would be welcome.

Never mind, I just found in the arch-wiki that on arch dmd and libphobos are build without PIC support. Which seams to be causing the problem. The easiest way is to compile using clang instead.

CC=/usr/bin/clang dub

Alternatively get gdc with PIC support.

Sorry for the necromancy. I have been searching for a solution for a couple hours. Did not expect to find something shortly after posting...

On arch linux there should not be any issue. Archlinux does not use fPIC by default so, this error seems like you have something wrong with your Archlinux installation.

Thanks for the tip. I haven't done a lot of development on linux so I messed quite a bit with my arch install. It's very well possible that I messed something up. I am planing to reinstall in a few weeks anyway :)

Having said that, from the arch wiki: https://wiki.archlinux.org/index.php/D_(programming_language)
Looks like there is a hardening-wrapper which forces PIC by default. As clang worked just fine I assumed that was the actual problem. I will look into it again once I reinstalled my system.
