error when putting gvrmain camera in project

the error says

 entry->m_rect.width ==width

what do you think is the problem

“==” is used for comparisons. For assignments use “=”.

entry->m_rect.width = width;

By just removing the water i had then the problem was gone . Thank you for the answer Mr. @doublemax
,I already got the solution @doublemax what i did was delete the water i have in my terrain.

My speculation is that it affects my camera view .
