Mat file API using C++ and Qt

pmathia0

Hi,
I have problem running "Read MAT-File in C/C++" from Matlab examples.
https://www.mathworks.com/help/matlab/matlab_external/creating-a-mat-file-in-c.html

When I compile it from matlab command window using mex, everythink is ok, mat file is created.
When I use the same msvc compiler parameters in command line, everything works fine.
When I create simple console application in VS2015 and setup the project to use mat-file api (includes, libs), everything works.

However, when I try to setup my QT application project to use mat-file api, it builds, but running the app gives me this error:

Is there some problem with conversion from Unicode? I read some article that Qt is abandoning ICU converters.

Hi and welcome
The link to the error demands login so people cannot see it :)

Thanks for reply, should be ok now :)

@pmathia0
super.
One thought, Could there be more that one version of that DLL ?
So that in Creator it somehow gets another one ?

@mrjj I haven't found another one. I have only one version of Matlab installed - 2016a, it's only 64bit version. I have completely reinstalled my windows because I had 2015 version before and saw some posts in Matlab forum that it could be the problem. But reinstall didn't solve anything. :(
And I'm using Visual Studio 2015 with Qt addin.
I think that I'll use .csv files for now in my semestral project, and maybe later when there's some time left, I'll try to solve this issue with mat files...

Its odd then.
sounds like a good plan.
csv should be fast to get up and running. :)
