Hi

I have started working on Qt very recently and have been able something by following this forum. I basically work on signal processing algorithms. I have created a C shared library using the Matlab C Compiler. I wanted it to be integrated to my Qt Project.

Before adding the library, I first created a standalone C Executable, to see if the code runs. It does. I get Matlab Plots as well. Everything all right till here. But that's not what i want. I need to change the parameters on from the Qt. Hence, the need for the library.

Since I am very new in it, I followed the forums and blogs to get it done. This is essentially what i followed.

My Project file looks something like this

When I try to run the code, the application stops working and it gives me following result : exited with code -1073741819


I tried to search in the forum and found that it might be an access violation. I ran qt as an administrator. Still the same

I don't understand where I am going wrong.

Please Please help me with this problem

Thanks & Regards
