I use this and it works for all my Unix releases (Linux, FreeBSD, NetBSD, MacOs):

Code: Pascal  [Select][+][-]
  1. -Cg -k-pie -k-znow

I only have problems with OpenBSD amd64/aarch64, here the result dont show a pie executable.

Without wanting to divert the thread, I can confirm that -k (or the equivalent, as shown, from the Lazarus IDE) is useful for all sorts of things.

The important thing is no extra spaces, and the right number of dashes as required by the linker.

Proper hardening needs -

 -Cg  -k-pie -k-znow

As I mentioned above. And demonstrated with (any recent) 'file' command.

While obviously I have no idea whats planned its worth noting that those PIE options are not there for FPC, they are passed directly to the linker. Maybe the same applies to -statis-pie ?

Further research is indicated ....

However,the linker's(ld's) -static-pie option is depracated now,I don't know why depracate that.
But gcc still have this option.

I have discovered that combine -k-pie -k--no-dynamic-linker can make static pie.
