我想为Android设备构建此仓库 https://github.com/shadowsocks/badvpn
我遵循 https://github.com/shadowsocks/badvpn#installation 并执行以下命令
cmake .. -DBUILD_NOTHING_BY_DEFAULT=1 -DBUILD_TUN2SOCKS=1 -DCMAKE_SYSTEM_NAME=Android
make install
我使用了CMAKE_SYSTEM_NAME标志来定位cmake文档中提到的android设备 https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html#cross-compiling-for-android
我正在使用从以下网站下载的NDK修订版18b（2019年1月） https://developer.android.com/ndk/downloads/older_releases.html
运行make install后，出现以下错误：
