Error: thumb conditional instruction should be in IT block - on ARM

[MarKS]

I am trying to build a opencv project with QtCreator on ODROID-XU4.
But Qt fails to build the project no idea why. Is it a Qtbug? How do i resolve it ?
Please help.

I'm sure you pasted the error message to Google and in a second found for example this:
"Compilation error on ARMv7 with -mthumb"
https://gmplib.org/list-archives/gmp-bugs/2013-July/003095.html

...which gives you the idea that the compiler directives should be changed.

@mvuori yes i did check these solutions but i have no idea about these compiler directives. How do i use them in QtCreator. And it throws error for only one project and my other projects are working fine.
