Question

我正在尝试在Windows 7（64位）上使用Cmake编译OpenCV。它将与Eclipse和CDT一起使用，我在其中阅读了您无论编译器如何都要指定Unix Makefile的地方。现在，鉴于我也有cygwin（对于Android NDK的东西），我首先尝试使用它的编译器，我成功配置CMake并生成makefile，但只有63％的编译，当OpenCV吐出错误时（关于ffmpeg和HMODULE）。所以我切换到MinGW（带有它的HelloWorld也很痛苦，我不得不指定MinGW g ++的完整路径，无论PATH变量设置如何），但现在我甚至无法配置CMake。我收到以下错误：

The C compiler identification is GNU
The CXX compiler identification is GNU

It fails with the following output:

Configuring incomplete, errors occurred!

如果有人知道可能存在什么问题（与cygwin shell冲突？），我会感激任何意见。提前谢谢！

Answer 1

我们遇到了与“Unix Makefiles”生成器相同的问题。我们使用“MSYS Makefiles”生成器解决了它（Msys是MinGW周围的shell环境，就像[一个非常小的] cygwin）。

Answer 2

此错误消息文字：

CMake Error: your RC compiler: "CMAKE_RC_COMPILER-NOTFOUND" was not found.
  Please set CMAKE_RC_COMPILER to a valid compiler path or name.

表示“windres”（对于mingw和基于cygwin gcc的构建树）不在PATH中。

windres支持，最近在CMake 2.8.4中添加了编译Windows资源（* .rc）文件。也许在你的MinGW环境中没有windres？

使用MinGW和Eclipse CDT进行CMake
