Re: [Plplot-devel] windows/mingw32 build questions
Hi, I believe cmake can be told to be very verbose about its configuring. Don't have time now, but a quick search showed that cmake --debug-output might be of any help to you.

I have just committed (revision 10153) the hard-landing solution because there is no way I wanted to have both ccmake and cmake-gui provide broken language results such as found by Hazen and confirmed in detail by me. However, immediately after I did that commit, the CMake gurus on the CMake list came up with a temporary workaround for bug http://public.kitware.com/Bug/view.php?id=9220. The workaround should provide a soft landing for both the missing and broken compiler cases which I think will work quite well. However, the implementation of this idea (to run a simple cmake configuration from within cmake to check on each compiler in question) is non-trivial so it will take me a while to finish with this issue. So more later. I believe I have now (revision 10157) finished this saga. The new soft-landing method (issue a warning message, disable that component of PLplot, and continue) when compilers are missing/broken seems to work well. For example, it appears to work both for cmake and cmake-gui. Please try it out. I have also enabled the D compiler by default since its examples are fairly complete and the bindings and examples build without issues. Previously, we were rather reluctant to enable a new language by default, but now that a missing/broken compiler only causes a warning, I believe the criteria for enabling a language by default do not have to be quite so severe as before.
