Hi Walt, I have seen such behaviour before – with some environments output to the console is either buffered or dropped. The command-line options, like “./a -dev wingcc” should work though.
If the program stops immediately when run in a Windows console, then there is a good chance that it stops because it could not find one or more of the DLLs it depends on. If you run it from a file manager like Windows Explorer you may get a message box showing the name of the missing DLL. My tool of choice to find out which is “dependency walker” – http://www.dependencywalker.com/ or the newer rewrite at https://github.com/lucasg/Dependencies.

Pls ignore the statements about the examples--all bogus. I do have 5.15.0 in my Msys2. When I compile in an Msys window, ./a just hangs. If I type a "1", the graph is generated on the screen. The display options usually do not show up at all. When I compile with exactly the same compiler in a Windows command window, it executes and terminates immediately with no output. Apparently running an Msys terminal sets something that helps,, but it is still not right. If this suggests anything to anybody, please let me know. In the meantime, I will try to build plplot from source. I have no confidence that it is the fault of Msys, given my lack of expertise about all this, so am reluctant to submit a bug. But maybe I will if I can my own build to work. Thanks. On Mon, Dec 23, 2019 at 8:25 PM Alan W.

[...] Hi Walt: The Fortran examples were historically rewritten a long time ago but not any time recently. Therefore, I am virtually positive you are seeing an old version of the PLplot fortran examples because you have accessed an old official MSYS2 package version of PLplot. What happens if you do a general update of your MSYS2 platform following the [MSYS2 instructions for doing that](https://github.com/msys2/msys2/wiki/MSYS2-installation<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fmsys2%2Fmsys2%2Fwiki%2FMSYS2-installation&data=02%7C01%7C%7C831500c32ab84bfb131908d788a97af0%7C15f3fe0ed7124981bc7cfe949af215bb%7C0%7C0%7C637128133815636572&sdata=p5Hk9W4J5Um9OqEORnV1DgDSN4u8SNQenCeWVQfGuH8%3D&reserved=0>)? My bet is you will then have access to the latest official packaged version of PLplot which is our latest release (5.15.0). By the way, we are normally quite happy with the MSYS2 platform for PLplot. For example, as part of the 5.15.0 pre-release testing, Arjen has had good Fortran (and much other) success on MSYS2 with a PLplot version that he built himself. However, as far as I know he has never tested the official MSYS2 PLplot package there which has been packaged by the principal packager for MSYS2 (alexpux) who is familiar with MSYS2 but not PLplot. So if it turns out that official MSYS2 packaged version of PLplot-5.15.0 does not work, you should prepare a bug report for MSYS2 and revert to using a 5.15.0 version that you built yourself on MSYS2 just to follow closely what Arjen did for his test. And with any luck at all, you should be able to replicate Arjen's Fortran success with that method. Alan __________________________ Alan W.
