Hi Philipp, I just need more information to be of any help.

You working with the MinGW compiler in a MSYS environment, right? Are you using wxWidgets 2.8.0 for a special reason? There is already wxWidgets 2.8.9 available, which I use without problems. Which version of cmake are you using? > > My configuration and building steps are as follows (from the root > dir of the PLplot distribution): > > PATH=/c/Program\ Files/CMake/bin:$PATH > export PATH > > $ mkdir gxxBuild-mingw-Debug > $ cd gxxBuild-mingw-Debug > cmake .. -G "MSYS Makefiles" -DBUILD_TEST=ON \ > -DCMAKE_VERBOSE_MAKEFILE=ON -DDEFAULT_NO_BINDINGS=ON -DENABLE_cxx=ON \ > -DENABLE_wxwidgets=ON -DwxWidgets_USE_DEBUG=ON - > DCMAKE_BUILD_TYPE=Debug > make Some remarks: you don't need CMAKE_VERBOSE_MAKEFILE=ON, just skip that and if you want verbose output run make VERBOSE=1 So far I didn't know about -DwxWidgets_USE_DEBUG=ON, but I never used MSYS, since I don't like it.

Does it link against the debug libraries (libwxcore2.8d.dll or similar) if you use -DwxWidgets_USE_DEBUG=ON. And does it link against the release libraries (libwxcore2.8.dll) if you skip this option. > > > Then I wanted to test it: > I copy the *.fnt files to the respective example directory and let > PATH additionally point to gxxBuild-mingw-Debug/dll (because I did > not yet "make install" PLplot) and to the wxWidgets dlls. sounds good. > Then regardless of the example (e.g. c++/x10 or c++/wxPLplotDemo) > very soon a crash occurs (Access Violation). When does it crash? Before you can select a driver?

This crash also happens without - > DENABLE_wxwidgets=ON, but with -DwxWidgets_USE_DEBUG=ON. If the wxWidgets bindings are disabled, wxPLplotDemo shouldn't be build, but the wxWidgets driver should still be available. > > > This does not happen iff I configure without -DwxWidgets_USE_DEBUG=ON. I have problems with cmake, since if you want to use the debug version of the wxwidgets library, cmake links to the correct debug library, but doesn't define the WXDEBUG macro in the command line (I don't know about MSYS, since wx-config should actually provide the correct settings). Therefore the wxWidgets code in the plplot library "believes" that it will be linked against the release library. Usually you get a message box at the startup telling you, that the code and the wxWidgets library don't fit and exits. I already asked the cmake developers to change that, but this didn't happen so far. It crashes maybe for you, since you use an older wxWidgets version. For that reason I usually use the release version of the wxWidgets library, even if I compile the plplot library in debug mode. Usually I don't need to debug the wxWidgets code, so no problem here. If this is acceptable for you, I would also just do it that way. One other proposal: You could run the example in gdb and print out the backtrace to see where it exactly crashes. In any case I would suggest, that you use the latest cmake version (2.6.2 or 2.6.3?) and the latest wxWidgets version (2.8.9). You could also try a "newer" PLplot version, we provide weekly source packages here http://www.miscdebris.net/plplot_weeklies/ There were a lot of improvements/changes especially for the wxWidgets driver, so you may try one of the later source packages or wait until next week, when PLplot 5.9.1 should be released.
