https://issues.dlang.org/show_bug.cgi?id=5278 --- Comment #32 from Martin Nowak <code@dawg.eu> --- This also affects Ubuntu 16.10 to some degree. [Hardened system tutorial/patch](http://forum.dlang.org/post/paeiukmlqrmgwieabvun@forum.dlang.org) [Cannot link with libphobos2.a with GCC 6.2 on Ubuntu 16.10](http://forum.dlang.org/post/tppsgztsbsdrtkpcbtak@forum.dlang.org) Using -fPIC -defaultlib=libphobos2.so (the normal shared flags) was reported to be a workaround for the missing -fPIE support on Ubuntu 16.10. https://github.com/rejectedsoftware/ddox/issues/134 -- |

Binaries built this way are PIE and have Phobos linked dynamically. I didn't manage to find a configuration that allows me to statically link Phobos, with or without PIE. -- |

All other combinations seems to fail in one place or another. See: https://issues.dlang.org/show_bug.cgi?id=16794 Alternatively, it *may* be possible to get away with non-PIC libphobos.a if there's a way to coax dmd to invoke gcc (used as the linker) with -no-pie. I tried -L-no-pie but that didn't seem to do the trick either. Probably something else is needed to make it work. -- |

Executables compiled with dmd's `-fPIC` do create PIEs. -- |
