https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233707 --- Comment #14 from Tijl Coosemans <tijl@FreeBSD.org> --- (In reply to Shawn Webb from comment #13) -fPIE =3D=3D -fPIC + some optimisations that only apply to executables.=20 Executables can access their own global variables and functions directly.=20 Libraries cannot (unless the variable is declared with protected visibility) because a symbol with the same name can be defined in the executable or ano= ther library and the symbol can be resolved to that one. So you can compile executables with -fPIC but you should not compile shared libraries with -fP= IE. --=20 You are receiving this mail because: You are the assignee for the bug.=
