dladdr and Dl_info

[Vincent R.]

Hi,

I am trying to compile llvm on latest cygwin and I get an error about
missing
definitions for Dl_info and dladdr.

const llvm::sys::Path& CIndexer::getClangPath() {
  // Did we already compute the path?
  if (!ClangPath.empty())
    return ClangPath;

  // Find the location where this library lives (libCIndex.dylib).
#ifdef LLVM_ON_WIN32
  ...
#else
  // This silly cast below avoids a C++ warning.
  Dl_info info;
  if (dladdr((void *)(uintptr_t)clang_createTranslationUnit, &info) == 0)
    assert(0 && "Call to dladdr() failed");

  llvm::sys::Path CIndexPath(info.dli_fname);

  // We now have the CIndex directory, locate clang relative to it.
  CIndexPath.eraseComponent();
  CIndexPath.eraseComponent();
  CIndexPath.appendComponent("bin");
  CIndexPath.appendComponent("clang");
#endif

  // Cache our result.
  ClangPath = CIndexPath;
  return ClangPath;
}

Could it be possible to provide an implementation ?

Thanks
