这是我所做的.

在 Qt Creator 的工具 -> 选项菜单中，在构建和运行"部分下有一个选项，上面写着使用 jom 而不是 nmake".我检查了那个框，但没有任何改变.因此，我转到了项目的构建设置，在构建步骤类别下有一个制作"项目.展开有关的详细信息，您将找到覆盖 mingw32-make.exe:"项.我在那里粘贴了C:\QtSDK\QtCreator\bin\jom.exe"，突然间我正在构建多核.

In the Tools -> Options menu in Qt Creator, under the "Build and Run" section there's an option that says "Use jom instead of nmake". I checked that box, but nothing changed. So instead, I went to the project's build settings and under the build steps category there is a "Make" item. Expand the details on that and you'll find a "Override mingw32-make.exe:" item. I pasted "C:\QtSDK\QtCreator\bin\jom.exe" in there, and suddenly I was building with multiple cores.

在 Qt Creator 2.4.1 上为我工作.试试看.

Worked for me on Qt Creator 2.4.1. Give it a try.
