No: $ ghc --make -dynamic -o setup Setup.lhs Linking setup ... $ export DEB_BUILD_HARDENING=1 $ ghc --make -dynamic -o setup Setup.lhs Linking setup ... /usr/bin/ld.bfd.real: Setup.o: relocation R_X86_64_PC32 against undefined symbol `newCAF' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld.bfd.real: final link failed: Bad value collect2: error: ld returned 1 exit status However, I have hardening-wrapper installed on my system, which installs new /usr/bin/gcc etc. to take account of hardening settings, AIUI.
