Use the dyld to show more meaningful message when a symbol is missing. The dynamic library manager's dyld can search a symbol in the library path. This patch uses that functionality to aid the 'unresolved while linking' diagnostics. Now we get: cling -L lib/ **************** CLING **************** * Type C++ code and press enter to run it * * Type .q to exit * ******************************************* [cling]$ extern int gErrorIgnoreLevel; [cling]$ gErrorIgnoreLevel IncrementalExecutor::executeFunction: symbol 'gErrorIgnoreLevel' unresolved while linking [cling interface function]! Symbol found in '/.../lib/libCore.so'; did you mean to load it with .L /.../lib/libCore.so ?
