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.

You probably have lua5.2 installed, which provides cyglua-5.2.dll rather than 
cyglua-5.1.dll.

I'm not sure what you mean by the "normal" download, but cyglua-5.1.dll is part 
of the lua5.1 package, and the latter is required by gnuplot.

It should have been.

As I mentioned above, you will need to install (or reinstall) lua5.1. You can 
discover this kind of thing by going to the Cygwin website and clicking on 
"Search Packages" in the left column.

You should subscribe to the cygwin mailing list (or use something like gmane). 
The custom on this list is not to CC individuals, though I've made an exception 
this time to make sure you get the message.

The command 'cygcheck /usr/bin/gnuplot.exe' should give you that 
information.

gnuplot 5.x.x.x not starting correctly in 64-bit CYGWIN console

[John J Ottusch]

I think this problem is related to the fact that I have both 32-bit and
64-bit versions of CYGWIN installed on my Windows 7 PC. They are on the 
same disk but in different directories (/cygdrive/c/win32app/cygwin vs. 
/cygdrive/c/win64app/cygwin).

So far I have observed the problem only when I try to run the version of 
gnuplot that comes with the most recent 64-bit CYGWIN installation. I 
believe gnuplot v4.x.x.x had been working in 64-bit CYGWIN before I 
updated.

I always run gnuplot from an X11 or rxvt console window within the 
CYGWIN environment. I'm using v4.4.4 with my 32 bit CYGWIN installation 
without any problems. 

I just updated my 64 bit CYGWIN installation in order to try out gnuplot 
v5.x.x. I didn't load absolutely everything, but I did accept all 
automatic dependencies. Installation went smoothly and all seems to work 
fine except for gnuplot.

Observations:

1) When I type gnuplot into a 64-bit console window it returns 
immediately to my prompt with no visible message instead of entering 
interactive mode. 

In this case my PATH is
/usr/local/bin:/usr/bin:/cygdrive/c/Windows/system32:/cygdrive/c/win32ap
p/cygwin/bin

2) However, doing the above with /cygdrive/c/win32app/cygwin/bin removed 
from my PATH (or replaced by /cygdrive/c/win64app/cygwin/bin) produces 
this error message:

C:/win64app/cygwin/bin/gnuplot.exe: error while loading shared 
libraries: ?: cannot open shared object file: No such file or directory

So something in /cygdrive/c/win32app/cygwin/bin is making a difference. 
Hard for me to tell from the error message which shared library it is 
looking for.

3) I wouldn't necessarily expect it to work correctly if I try to start 
gnuplot.exe directly from the filename in Windows Explorer, but at least 
I get an error message -- "The application was unable to start correctly 
(0xc000007b). 


Any suggestions on how to fix or debug the problem would be appreciated. 

John Ottusch

PS. I tried attaching the outputs from 'cygcheck -s -v -r' for cases 1 
and 2 but that message apparently got bounced somewhere along the line.
