Help: can't run app with qwt in windows

Hi,

Although I have successfully build qwt 5.2.0 in windows XP (using mingw32 compiler), I can't run my app against qwt. If I link to qwt in my program (I use a simple QwtPlotCurve to plot 2d data), the program will fail to run. Windows pops up a dialog that says "The application failed to initialize properly (0xc000005). Click OK to terminate the program"!

I also notice that although all the examples were built ok, only a few of them can run. Of those are: curvedemo1 and curvedemo2. All other fialed to run with an error like this: "Runtime error. This application has requested the Runtime to terminate it in a most unusual way. Please contact the developers for detail"!!!

Have anyone run into the same problem? Any help to get around this?

Also since I built it using mingw32, I suspect some flaw or incompatibility with this compiler and would like to try building it with MSVC. However, I don't know how to generate the project files for msvc to build. If i run the batch file msvc-qmake in admin directory, I get a bunch of warning that says it could not generate files in directory, ... Although I have tried to make those directories writable, it still does not work.

Any help here is greatly appreciated.

Sincerely,

John.
