I would like to discourage you from the direction you are headed. I think what you want to do is possible because we solved similar issues in the build tree, but the changes would be more extensive than just some changes to plplot-test.sh.cmake so the cost of that solution is a lot of complexity that I don't want to see in the installed examples case. As you have already indicated, a complication when the prefix is "/usr" is the ordinary user (normally) has no write access. So they cannot do any of the builds of the examples for compiled languages that are necessary before they can even execute plplot-test.sh. To solve this issue, I guess the rpm could compile the examples after they are installed, but then that subverts one of the principal motivations of the examples which is they teach (by example) the users how to use PLplot from their language of choice even when that language is a compiled language. This is an example of the increased complexity I mentioned above to get a complete solution to the problem using the direction you are headed. Furthermore, certain of our example languages (I believe tcl is one of them which would explain your above error) are set up in such a way that the example must be run from the appropriate subdirectory of examples. To deal with this issue will require still more complexity. Here is the simple approach I would like you to promote instead of the direction you are headed. Copy the entire installed examples directory tree to somewhere under the control of the user, and then execute "make test" in that copied directory. This is the method I preferentially use, and it is already documented at http://www.miscdebris.net/plplot_wiki/index.php?title=Testing_PLplot. Thus, to deal with the overall "writeable directory" issue all you have to do for Fedora users is copy that documentation or point to it. Of course, that still leaves the issue discussed previously of checking the subdirectory existence when installed examples have been split from each other into subpackages which may or may not be installed by the user. I would be happy to commit such a patch that has been tested by you for the split examples case. Alan __________________________ Alan W.
