当尝试使用Cmake和Android NDK编译项目时，它表示以下内容： C ++ Comnpiler“ / opt / android-ndk / toolchains / llvm / prebuilt / linux-x86_64 / bin / clang ++”无法编译简单的测试程序。
我正在使用Cmake 3.8和Android NDK r18。 在CMakelists中，CXX编译器设置为g ++，所以我不知道为什么要使用clang ++。
CMake将无法正确生成此项目。 呼叫堆栈（最近的呼叫优先）： CMakeLists.txt：9（项目）
-检查工作的CXX编译器：/ opt / android-ndk / toolchains / llvm / prebuilt / linux-x86_64 / bin / clang ++-损坏 在/usr/share/cmake/Modules/CMakeTestCXXCompiler.cmake处的CMake错误：45（消息）： C ++编译器
"/opt/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/clang++"
无法编译简单的测试程序。
它失败，显示以下输出：
