Issue ID: 16794 Summary: Official .deb packages must compile libphobos2.a with -fPIC Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: critical Priority: P1 Component: phobos Assignee: nob...@puremagic.com Reporter: hst...@quickfur.ath.cx The latest versions of Debian / Ubuntu ship with gcc-6.2 configured with PIE by default. Because of this, existing .deb packages of the dmd toolchain will not be able to link D executables due to incompatibility between non-PIC code in libphobos2.a and PIC code generated by default when gcc is invoked by dmd. Recommend to change the official build scripts for .deb packages so that PIC=1 is specified by default for druntime/phobos builds, so that libphobos2.a is compiled with -fPIC. Note that this will also require that the default dmd.conf specify -fPIC in the default compiler flags, otherwise users may still run into PIC/non-PIC incompatibility problems.
