Well, yes. generally speaking, all code in a DSO should be PIC, and that includes code pulled in from libraries. > According to the documentation[1] this flag shouldn't have any > effect at all because I am building for 64 bit Intel. I can't find that reference. Can you please quote the section to which you are referring? > My question is, is this expected behavior?
