Hi Werner:
I was curious to see whether the memory management problems found by Winson
also showed up on Linux so I tried building wxPLplotDemo.cpp in the install
tree.
Here is how I built it on Ubuntu Dapper:
[EMAIL PROTECTED]> /usr/bin/c++ wxPLplotDemo.cpp -o test -Wl,-rpath
-Wl,/home/software/plplot_cvs/installcmake/lib:/home/software/autotools/install/lib
PKG_CONFIG_PATH=/home/software/plplot_cvs/installcmake/lib/pkgconfig
pkg-config --cflags --libs plplotd-wxwidgets `wx-config --cflags --libs`
N.B. the wx-config part is currently required, and I comment on that issue
below.
I then tried valgrind on test, and it was valgrind clean (and also produced
a nice plot). Thus, the wxwidgets example and bindings both seem fine
on Ubuntu Dapper.
Werner, I suggest you ask Winson to try to build wxPLplotDemo.cpp. If he
gets a good result, then there is something wrong with his experimental code
where he is having problems, and he should follow the wxPLplotDemo.cpp more
closely. If he gets a bad result, then obviously the wxwidgets bindings or
the example need to be fixed for Winson's platform.
Note, since we must configure plplotd-wxwidgets.pc in any case to give the
users access to our wxwidgets binding library, then I think it is less
complicated for the user (and consistent with the approach used for all the
rest of our bindings) to not require them to supplement pkg-config with
wx-config like I had to do above to build the wxwidgets example. The
required changes to the configuration of plplotd-wxwidgets.pc are clear. We
already have ${wxWidgets_INCLUDE_DIRS}, ${wxWidgets_DEFINITIONS}, and
${wxWidgets_LIBRARIES} internally available for our CMake build system so it
is a straightforward matter to configure plplotd-wxwidgets.pc with those
variables (appropriately transformed to the pkg-config form as in the other
bindings).
Werner, are you willing to go along with this approach? If so, I will take
responsibility for implementing it.
Alan
