<qopengl.h> library .lib?

[giugio]

hello , i use <qopengl.h> header for my experiments in opengl and qt.
The problem is that i create a small library with templates, all the files are .hpp .
When i must test the project i must import all the needed .hpp files in the test project, but i don't have a library(.lib) for the called gl primitives function like bindBuffer createbuffer ecc , and this is the result:


2>main.obj : error LNK2019: unresolved external symbol glBindBuffer referenced in function "public: void __cdecl OPEN::CShaderParItemVbo<struct glm::detail::tvec3<float> >::Create(unsigned int)" (?Create@?$CShaderParItemVbo@U?$tvec3@M@detail@glm @@@OPEN@@QEAAXI@Z)

What library i must import for the <qopengl.h> header with qt?
thanks.

i use 64 bit libraries , may be the problem ?
where i can find an opengl32 for the 64 bit?
thanks.

Which version of Qt are you using?

[giugio]

version 5.1

[wysota]

Have a look at QOpenGLFunctions class.

thanks it works.
but this function is not supported :
glGenVertexArrays

is not possible to use the standard gl functions?
Why there is this problem in qt with the libs?
ps. i use the compilation at 64 bits.
thanks.
