Hi! Are there any news about the status of packaging dmd for archlinux? The last dmd compiler packaged is 2.074.0 and since the last batch of updated packages in archlinux, dmd generated objects fail to link with libphobos with erros like these: /usr/bin/ld: /usr/lib/libphobos2.a(object_a_66e.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile con -fPIC /usr/bin/ld: /usr/lib/libphobos2.a(object_b_58c.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile con -fPIC /usr/bin/ld: /usr/lib/libphobos2.a(object_c_7f4.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile con -fPIC /usr/bin/ld: /usr/lib/libphobos2.a(object_d_a07.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile con ...

A. CorbiHm, I can't reproduce this issue with dmd 2.074.0-1. I've just installed dmd and it works out of the box: ``` ➜ arch tmp% pacman -Q | grep phob libphobos-devel 1:2.074.0-1 ➜ arch tmp% pacman -Q | grep dmd dmd 1:2.074.0-1 ➜ arch tmp% cat test.d import std.stdio; void main() { writeln("hello!"); } ➜ arch tmp% dmd -c test.d ➜ arch tmp% dmd test.o ➜ arch tmp% ./test hello! ```

A. CorbiI think the Arch Linux TUs are in the process of enabling -fPIC by default, see e.g. [1] - it might be releated to this? In any case - building dmd/druntime/phobos with -fPIC enabled is a good idea and since 2.072.2 the official releases do so. Not sure why it's not done on Arch, maybe because Dicebot stepped down as maintainer? (see [2, 3]).
