Hi Ishwar,

Would you mind to clarify which operating system edition of ChartDirector you are using? Does that match the operating system of your Qt?

For example, if you are using Qt for Linux x86_64  (64-bit Linux), please make sure you have downloaded ChartDirector for C++ for Linux (x86_64) "chartdir_cpp_linux_64.tar.gz".

I have attached a screen shot for your reference. I used Ubuntu Linux (x86_64), so I downloaded "chartdir_cpp_linux_64.tar.gz" and then extract it right on the desktop. (You can see the ChartDirector folder on the desktop.) Then I start Qt Creator 5.6.0, which I downloaded from the official Qt web site. In Qt Creator, I open the Qt project file "ChartDirector/qtdemo/realtimezoomscroll/realtimezoomscroll.pro", and then just press the "Run" button to compile and run it.

If the above still cannot solve the problem, would you mind to clarify your exact OS,  including the OS version and Linux brand if applicable. Also, please inform me of your Qt version and operating system type, and how do you compile the code (eg. using qmake/make from the command line, or using Qt Creator)? It would be useful if you could provide a screen shot showing the compiler output similar to the screen shot I attached.
