On Linux, etc., when a shared library is missing at runtime, any attempt to execute a binary depending on it will get an error like: % /usr/bin/xvidtime /usr/bin/xvidtune: error while loading shared libraries: libXdmcp.so.6: cannot open shared object file: No such file or directory I'm pretty this message is coming directly from (in this case) ld-linux.so (the "DLL loader" on linux). If Cygwin is intercepting the equivalent exception on Windows, perhaps a possible compromise would be for cygwin1.dll to emit such an error to stderr? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
