As of revision 12309 I have a solution that has completely gotten rid of those build errors (on my Debian wheezy platform) for the above case. The solution is to put the location (in -L, -l form) of the C++ library associated with the C++ compiler in the list of library options contained in the plplotd.pc file configured and installed by our build system for the case where BUILD_SHARED_LIBS is not true, i.e., for the unique static libraries case where the plplotd library turns into a static C++ library (because of the C++ device driver code that is part of the library in that case). @Andrew: I have mentioned some CMake logic caveats concerning finding the C++ library associated with the C++ compiler in the commit message for revision 12309. For example, for compilers other than GCC C++ compiler the plplotd.pc file will have incomplete linking information (just as before revision 12309), but everything else should work fine. If you have an idea to make the CMake code that attempts to find the C++ library associated with the C++ compiler more general, please go ahead and make further changes in src/CMakeLists.txt.
