I seem to be late to the party. What patch are you talking about?
If there is a patch that fixes this (i.e. makes gnuplot work with
wx3) I'm perfectly happy to test it out.
The one relevant patch I know about is a call into XLib to initialize threads.
That one is already in gnuplot's upstream source but is not in either 4.6.5
I can't say that patch makes a whole lot of sense to me, but it does indeed
allow running with wx3 my machines (Mageia 4). But it's clearly not a
complete solution as I still get alarming error messages at run time.
For me they are non-fatal, but Anton's stack trace shows a segfault
so I guess the situation is worse in the Debian build.
Can you point me to patches that allowed other Debian packages to
migrate from wx 2.8 -> 3.0? Perhaps there is a painless fix, but I'm
not likely to find it without a big hint from somewhere.
