Hi Corinna, based on the discussion on -developers list [1][2], here's a reworked set of patches for dlopen, split along these features and fixes.
[1] https://cygwin.com/ml/cygwin-developers/2016-06/msg00000.html [2] https://cygwin.com/ml/cygwin-developers/2016-08/msg00000.html *) Switch to pathfinder class for path search iteration, without any deliberate change in behaviour, but with the pathfinder::criterion interface to allow for more generic use eventually. *) Fix search order to search all basenames per one directory rather than searching all directories per one basename. *) For dlopen ("/path/lib/libz.so"), search "/path/bin/" first when the executable calling is located in "/path/bin/". This is for [3]. [3] https://cygwin.com/ml/cygwin-developers/2016-08/msg00020.html *) Consequently, dlopen ("libAPP.so") without an explicit path should search the executable's directory first, like the Windows loader does for linked dlls. Topics dropped for now: *) Extra GetModuleHandleEx is not that necessary to me, as it[4] turns out that LoadLibrary detects a dll as already loaded even if the underlying dll file has been replaced (renamed actually). [4] https://cygwin.com/ml/cygwin-developers/2016-08/msg00023.html *) Add PATH environment variable to list of searchdirs should not be necessary to me when the executable dir is added. Thank you! /haubi/
