QImage::Format_Grayscale16 not supported in 4.10.2 open source

During build of my project

[SachinBhat]

for your first question, i need only for just one of them. I added them just to debug if hid api is using any other package

To avoid problems and to not slow down Qt Creator launch, install only the Qt Kit you want to use, this will save space on your disk and time!
Qt Kit do never share packages, all libraries are build for a specific target + compiler combination, there no need to select all, the only things that are common are: Sources, Qt Charts, Qt Data Visualisation, Qt...

this look like a problem with you project file

[SachinBhat]

I do not get when i build with 5.3.2 version. So I believe it wont be a problem with my project file..

Interesting, which Qt Kit you are using for Qt 5.3.2:

• MSVC2013 64bit?
• MSVC2013 32bit?
• MSVC2012 32bit?
• MSVC2010 32bit?
• MinGW 4.8.2?

@KroMignon
I am using MinGW 4.8.2
Build build-GUI-Desktop_Qt_5_3_MinGW_32bit-Debug
I also get this error along with hid api error if it helps collect2.exe:-1: error: error: ld returned 1 exit status

Thanks

Here are the build settings for 5.13.2

I am lost, is this project working with Qt 5.3.2 or not?
It is very hard to follow your explanations.
What is working and what is not working:

• can you build with Qt 5.3.2/MinGW?
• can you run your project with Qt 5.3.2/MinGW?
• can you build with Qt 5.13.2/MinGW 32bit?
• can you run your project with Qt 5.13.2/MinGW 32bit?

can you build with Qt 5.3.2/MinGW? yes
can you run your project with Qt 5.3.2/MinGW? yes
can you build with Qt 5.13.2/MinGW 32bit? No
can you run your project with Qt 5.13.2/MinGW 32bit? No

I apologise if i was not being clear.

I had a working version with 5.13.2 when i installed all the packages after only removing 64 bit ones.

I uninstalled it for getting the open source. I install with the packages selected in the image i sent. It doesn't build the project

What does the hidapi.dll require exactly?

Thanks

As far as I know, hidapi.dll is not part of Qt, and a quick google search gives me ==> https://github.com/libusb/hidapi

So, how did you compile hidapi?

[SachinBhat]

I will let you know how the hidapi.dll was compiled by asking my team. Are the build settings correct?

[SachinBhat]

Let me mark this thread as solved as the topic is something else. I will start a new one with better explanation of the issue
