As a result, installations of LLVM in non-standard locations will not require passing custom -ccopt -L flags when building the binary, nor absolute paths would be embedded in the cma/cmxa files. Additionally, the executables will not require changes to LD_LIBRARY_PATH, although CAML_LD_LIBRARY_PATH still has to be set for ocamlc without -custom. See http://caml.inria.fr/mantis/view.php?id=6642. Note that the patch is approved, but not merged yet. It will be released in 4.03 and likely 4.02. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225778 91177308-0d34-0410-b5e6-96231b3b80d8
