我已經使用Go的go-gl包了很長一段時間了。一切工作100%,直到我做了一些重構,現在我得到了似有錯誤:調用gl.GenVertexArrays時出現內存錯誤

我想知道如果任何人有一個解決方案。我更新了我的驅動程序,並且空的OpenGL場景在不生成頂點數組的情況下100%工作

進行調用的函數:
var vertexArrayID uint32
// ERROR ON LINE BELOW.
gl.GenVertexArrays(1, &vertexArrayID)
gl.BindVertexArray(vertexArrayID)
// Vertex buffer
var vertexBuffer uint32
gl.GenBuffers(1, &vertexBuffer)
gl.BindBuffer(gl.ARRAY_BUFFER, vertexBuffer)
gl.BufferData(gl.ARRAY_BUFFER, len(verticies)*4, gl.Ptr(verticies), gl.STATIC_DRAW)
謝謝
沒有看到你的代碼,這是一個猜測:你試圖要求一個VertexArray的標識符將被存儲在一個空的var中。 – Ripi2
@ Ripi2我用導致錯誤的代碼更新了我的問題。希望它能提供更多關於這個問題的背景。 –
