Try `-defaultlib=libphobos2.so` with your dmd command line. The .so version is pic compiled.


Or you can recompile the whole lib.

I don't know how to do that from the command line. I don't want to hand modify the Makefile because I want this automatic.

Instead I tried

    make -f posix.mak AUTO_BOOTSTRAP=1

but that fails as

on Ubuntu 16.10. It seems we need fix the implicit conversion in cg87.c to match stricter type-checking in GCC 6.2.
