Enable Vulkan in Qt

Scapior

I want to use Vulkan API (QVulkanInstance, etc) in Qt. For this need build Qt from source fully? Or only QtGui enough?
I try build project on ...\Qt\5.10.0\Src\qtbase\src\gui, but got "Could not find feature opengl.*", and try configure.bat --gui, but got

D:/Programs/Qt/5.10.0/Src/qtbase/qmake/library/qmakebuiltins.cpp:512:32: error: '_pclose' was not declared in this scope
         int ec = QT_PCLOSE(proc);
                                ^
Makefile:254: recipe for target 'qmakebuiltins.o' failed

Hi and welcome to devnet,

It's available in 5.10 as described here. You need to have the required dependencies installed.
