>> The command 'cygcheck /usr/bin/gnuplot.exe' should give you that information.
>> Ken Doing so finds several required DLL's but also reports cygcheck: track_down: could not find cyglua-5.1.dll which is interesting because running the command lua enters an interactive mode (unlike gnuplot), which suggests that 'lua' might be working. If cyglua-5.1.dll is part of the normal 64-bit CYGWIN download then 1) I don't understand why it wasn't downloaded and installed automatically when I updated, and 2) I'm not sure what package(s) I would have to manually (re)install in order to get the 64-bit version, and 3) it may or may not fix the gnuplot startup problem. I might add that running 'cygcheck gnuplot' from my 32-bit CYGWIN installation finds cyglua-5.1.dll in C:\win32app\cygwin\bin\cyglua- 5.1.dll. Of course this version does not work with 64-bit gnuplot. jjo (Sorry for the lack of previous context, but I did not receive a copy of Ken's message in my e-mail box to reply to.) -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
