Is this the error you are talking about? Yes. Unless we are doing something wrong in our search for the *.so version of that library, that's a pretty basic bug in D support for shared libraries on Debian, and I cannot imagine why it hasn't been fixed yet. > > I also tried gdc-4.6 which is also available in unstable.

We have complete control of that Posix flag since we implement our own D language support. That is, -fversion=Posix is set in plplot_cmake_qt/cmake/modules/language_support/cmake/Platform/Linux-gdc.cmake and -version=Posix is set in Darwin-dmd.cmake and Linux-dmd.cmake in that same directory. So when the D language support was put together by the developers at http://www.dsource.org/projects/cmaked (which we have mostly just copied from although you should check their files again to see if anything has changed modulo the changes we have deliberately added since we copied their files), they must have thought "Posix" was an important flag. You may also want to check with the CMake D language support files at http://code.google.com/p/cmaked2/. "D2" is apparently a new variant of the D computing language (see http://d-programming-language.org/D1toD2.html). I don't know whether our D bindings and examples are written in that or D1 or whether gdc-4.6 compiles D1 or D2, but regardless of those D1 versus D2 questions, cmaked2 language support may actually be independent of whether we are dealing with D1 or D2 so what those D2 CMake language support files say about "Posix" may be relevant.
