Question

我目前正在使用C ++和Irrlicht游戏引擎在Visual Studio 2010中进行编码。我试过在他们的论坛上提出这个问题，但我没有得到任何回应。

我正在使用Irrlicht网站上的教程： http://irrlicht.sourceforge.net/docu/example002.html

我得到的错误是：“函数_main中引用的未解析的外部符号_ imp _createDevice”

我已添加链接Irrlicht库并已包含文件，但我仍然收到此错误。

{
// ask user for driver

        smgr->drawAll();
        driver->endScene();

        int fps = driver->getFPS();

        if (lastFPS != fps)

Answer 1

我设法建立了样本，没问题。

获取错误的唯一方法是混合32位和64位lib文件。

重命名64位库Irrlicht_x64.lib并尝试重新构建。

Irrlicht中未解决的外部问题
