Oh, my bad. I confused PIE with PIC.
So, just to be clear, -fpie is not passed by default on most systems, but it is
on mine (a feature of the hardened GCC). DMD's binary release of phobos is
then compiled WITHOUT -fpie because that's the usual course of things, thus
causing it to complain when I link it with something that compiles WITH -fpie.
Is there any chance that -fno-pie could make it into the list of things DMD
passes to GCC by default?
Assuming I understand this all correctly, then other systems won't care if
-fno-pie gets passed because they don't use PIE anyways. On my system it will
convert a dead-on-arrival binary release into something that works.
If someone still wanted to build with PIE then the ideal, I suppose, would be
to have portage (the package manager) build everything from source, adding
-fpie and -fPIC as necessary and adjusting the dmd.conf file to reflect it.
Also, is it even possible to get -fno-pie in there through dmd.conf?
When I add -L-fno-pie in dmd.conf it adds "-Xlinker -fno-pie" instead of just
"-fno-pie" to the GCC args and it seems to end up going to the wrong place.
Then I get linker errors and stuff won't build: http://pastebin.com/wEcuyUqp
