conan NDK 编译 boost报错:CMake was unable to find a build program corresponding to “MinGW Makefiles”

今天在Windows平台如下正常执行conan NDK交叉编译Boost库时报了个错

$ conan install boost/1.69.0@ -pr:h android_21_armv7a_clang -pr:b default --build missing

错误日志如下，看样子是在编译依赖库bzip2时出错了，还没到编译boost的阶段

似乎是需要MinGW编译器啊，刚才开始我的解决方法，就是装个MinGW编译器，将C:\\mingw64\\bin设置到环境变量PATH，然后就解决了这个问题。

但我还是觉得不太对，Android NDK交叉编译为什么需要MinGW(mingw64 )编译器呢?这不合理啊。

在Conan issue找到了同款问题：

《Some CMake Settings Passed On With Build Missing on Cross Build #3884》

真正的原因是没有指定CMake的GENERATOR,导致某些库的编译脚本误定义为MinGW Makefiles,下面是解决方法：

就是需要设置环境变量CONAN_CMAKE_GENERATOR为Unix Makefiles

可以如下在命令行临时设置环境变量：

set CONAN_CMAKE_GENERATOR=Unix Makefiles

也可以如下将它添加到profile,注意这里Unix Makefiles需要加引号(")

android_armv7a_clang

CONAN_CMAKE_TOOLCHAIN_FILE=$android_ndk\\build\\cmake\\android.toolchain.cmake
CONAN_CMAKE_GENERATOR="Unix Makefiles"
[conf]

CONAN_CMAKE_GENERATOR与上面profile中的CONAN_CMAKE_TOOLCHAIN_FILE一样都是conan自定义的环境变量,

关于conan 环境变量的说明参见Conan官方文档《Environment variables》
