Error when compiling in Visual C++ 2010 Express

Post by 14K » 2013-01-16T14:06:55-07:00

I have recently installed ImageMagick libraries for C++ and i have no prior experience with C++ GUI but I'm very good in C++ command line programming.

I have installed ImageMagick in windows through an exe file and copied libraries and header files to C++ but whenevr i am trying to run any demo program i am consistently getting this error.

Code: Select all

I desperately wants to know what is causing this error and why even the demo programs are not working ?
Kindly guide me.

You need a starting point, go to c:\Program Files\ImageMagick-6.8.1-Q16\Magick++_demos. Click on the button workspace, build, and run. Assuming that's successful, use the button workspace as a template for your own custom code.

Thank you for your response sir,

I've tried this too dozens of time and continuously getting this error.
The Project must be Converted to current Visual C++ project format. After it has been converted you will not be able to edit this project in previous version of visual studio.
Convert and open this project ?
When i click yes nothing happens nothing shows on the screen blank visual C++ screen with no project open.

it merits mentioning that i've installed Visual C++ 2010 x86 and downloaded ImageMagick for x86 , no idea what is mean by dynamic and static so i treid both but still no luck.
Its been like 23 hours i am trying to make it work.
Kindly guide me.
