The difficulty comes when you have many authors over many years and you need to get all their permissions.

I want to go D all the way. But if I have to get a libc, I will try and implement one in D. it is possible to implement libC on top of your code standard library in D so that D-only applications don't rely on legacy C code. Newlib is a portable libC implementation that is relatively easy (the linker errors might take you longer to sort than the code :) to get going. initially we implemented its '13 system calls' in C: https://github.com/wolfwood/buildtools/blob/xomb/newlib-files/syscalls.c but we eventually moved most of that code into D: https://github.com/wolfwood/xomb/blob/unborn/user/c/cbindings.d obviously most of the details will be different for your OS.

Just re-read the boost license and it says nothing about incompatibility with other libraries written in other licenses. How would it be a problem then that the D core libs are licensed with boost and this program isn't? Heck, even the GPL is compatible! http://www.gnu.org/licenses/license-list.html#boost

I might do 32bit, I have not decided yet, but I think I will skip it. I will not add ARM support because this would require alot more research. Maybe in the future when PowerNex is in a more feature complete state. The long term goal is that userspace programs should be able to use phobos.

Well, from the README I'd say the goal is a complete x86-64 OS The goal is to have a whole OS written in D, where PowerNex powers the core. This project looks great and it's not easy writing a x86-64 bootloader even with GRUB and a reference to work from, Nice work! bye, lobo
