Could you explain the problem with this? The choice of local-exec vs global-dynamic does not affect whether code is position independent. It's a difference between linking an executable versus linking a shared library; this is one of the distinctions between -fpie and -fpic. > But then readelf tells me: > > Relocation section '.rel.dyn' at offset 0x3d4 contains 2 entries: > Offset Info Type Sym.Value Sym.
