Good information about linkers and loaders can be found in the book Linkers and Loaders at


  • Get familiar with the fpc sources
  • Analyse what is available in the fpc sources. A couple of years ago a basic linker for go32v2 was already working.
  • Start coding, the first thing to add is a scriptable memory/file layout, like the ld-scripts.
  • Add PE coff support
  • Add static ELF support
  • Add shared ELF support
  • Add optimizations for smartlinking
  • Add internal object format
  • Keep an eye on memory usage and overall speed.
