Alan, Thanks Phil (I am CC you here, because this is a wxdriver issue; not saying that is a bug in the wxdriver, just a code error I have in my use of it )
The issue was not lack of -g, but just a code issue I am following almost verbatim the demo wxPLplotDemo.cpp what happens in my code is that pls is NULL here void Plot(wxPLplotwindow<WXWINDOW> *plotwindow) { wxPLplotstream* pls = plotwindow->GetStream(); so all pls-> calls seg fault what happens is that this function is *not* called void wxPLplotwindow<WXWINDOW>::OnCreate( wxWindowCreateEvent &event ) { if ( !m_created ) and it should have been in these calls wxPLplotwindow<wxFrame> *frame = new wxPLplotwindow<wxFrame>(); frame->Create(NULL, wxID_ANY, wxT("wxPLplotDemo")); frame->Show(); Plot(frame); This only happens in Linux, on Windows all is fine so, I'll keep on debugging to see what is happening by the way, since I am here, I have 2 small requests: 1) the wxdriver compilation has a couple of compiler warnings, would it be possible to eliminate them ? 2) would it be possible to keep in the upcoming version the old deprecated wxdriver code that is not templated ? I find templated code difficult to follow and debug, and here there is no benefit in using it , because all my plots are in wxFrame these are the warnings M:\star_icvs\tools\wx_lib\wx_plplotwindow.hpp(181): warning C4100: 'event': unreferenced formal parameter (compiling source file wx_explorer_star.cpp) M:\star_icvs\tools\wx_lib\wx_plplotwindow.hpp(182): note: while compiling class template member function 'void wx_PLplotwindow<wxFramePlot>::OnCreate(wxWindowCreateEvent &)' (compiling source file wx_explorer_star.cpp) wx_explorer_star.cpp(860): note: see reference to class template instantiation 'wx_PLplotwindow<wxFramePlot>' being compiled m:\star_icvs\tools\wx_lib\wx_plplotwindow.hpp(278): warning C4701: potentially uninitialized local variable 'drawDc' used m:\star_icvs\tools\wx_lib\wx_plplotwindow.hpp(278): warning C4703: potentially uninitialized local pointer variable 'drawDc' used for the first you can use the WXUNUSED macro like in void wxFrameClient::OnQuit(wxCommandEvent& WXUNUSED(eve)) the others seem that you should see m:\star_icvs\tools\wx_lib\wx_plplotwindow.hpp(278): warning C4701: potentially uninitialized local variable 'drawDc' used m:\star_icvs\tools\wx_lib\wx_plplotwindow.hpp(278): warning C4703: potentially uninitialized local pointer variable 'drawDc' used it says that the variables are not initialized and are potencially used -Pedro ----- Original Message ----- From: "Alan W.
