Agenda

  • update on RPATH support

Notes

RPATH support
  • Alan: $LD_RUN_PATH: very easy, just use $LD_LIBRARY_PATH

    • better option than wrapping compilers: what if someone links with ld directly
    • doesn’t work with ld.gold out of the box
    • needs patch, see https://sourceware.org/bugzilla/show_bug.cgi?id=13764
    • configure binutils with --disable-new-dtags to disable RUNPATH (and only use RPATH) may also be an option to ld
  • sanity check via readelf

  • figuring out what goes into $LD_LIBRARY_PATH may be tricky

    • recursively include all deps
    • set $LD_RUN_PATH through modules (rather than $LD_LIBRARY_PATH) ?
    • or construct $EB_LD_RUN_PATH and use that to define $LD_RUN_PATH
