R_SPARC_GOT10. Resembles R_SPARC_LO10, except that the relocation refers to the address of the symbol's GOT entry.

NettetIf not, then all of these absolute addresses need to have a suitable offset added to them—this is relocation. I'm not going to mention this topic again, though, because it's almost always invisible to the C/C++ programmer—it's very rare that a linking issue is because of relocation problems) Static Libraries
