This should not happen, -fPIC should be added automatically where required. Maybe it's caused by --enable-default-pie or any of the other flags which are not really needed? > * When invoking nix-build without specifying --cores 1 there are > problems when building libphobos; it looks like object files are moved > before they are generated.

I don't think make install is multi-thread safe, but make should actually be fine. > * I have disabled bootstrapping for now to speed up the debugging > process, hopefully it can be enabled again later on. > > I have taken the compiler flags to be used from > https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=gdc-git, which > was linked in another thread on this forum, but maybe this is too > specific for Arch? Yes, these are actually arch and not gdc specific. You do not need any special flags for gdc, just add d to --enable-languages= and you should be fine. --with-target-system-zlib=yes is the only D specific flag in your github pull request, and it forces libphobos to link against the system zlib instead of including a copy. You'll have to decide whether this is the behavior you want. -- Johannes
