最佳答案
我目前正在尝试让 CMake 在我的 Windows7(64位)系统上运行。我想编译 TagLib,以便以后与我正在开发的 Qt 应用程序一起使用。我想用 MinGW 编译它(而不是像在 另一个问题中那样使用 Visual C + +)。
我下载了安装程序(CMake-2.8.3-win32-x86.exe)并安装它(我还选择将 CMake 添加到路径中)。然后转到 CMakeLists.txt 文件所在的目录并运行 cmake .
。然后它给了我这个巨大的错误。

我有点惊讶的是,它失败了这么艰难的盒子,考虑到它宣传自己是一个跨平台的作品。
我尝试将 INCLUDE、 LIB 和 LIBPATH (Windows 环境变量)全部设置为 MinGW 二进制文件目录(C: MinGW bin) ,但它仍然给我同样的错误。我还尝试将 CMAKE _ C _ COMPILER 和 CMAKE _ CXX _ COMPILER 设置为 g + + 的位置(C: MinGW bin g + +)。
有人知道这是怎么回事吗?
解决方案:
根据 tibur 的建议,我运行 cmake GUI 来创建 make 文件。
然后进入目录 taglib 目录并运行 mingw32-make.exe
来完成实际的构建。
