I have now (commit id d8d9999) implemented and tested that change. Please check that it works also for you. One peculiarity that occurred for examples/c/x08c.c is that the C++ compiler apparently treats explicit declarations in the code differently than those same declarations in headers. So the explicit declaration of plexit failed to work while replacing that with #include "plplotP.h" to declare plexit (which I did in the above commit) worked fine. Can any C++ expert here explain this peculiarity of that language? Alan __________________________ Alan W.
