gcc - 如何在 Android 上使用带有 gcc 的 NDK？

问题描述

我需要编译 OpenCV 2 来测试一些东西，它只能用 gcc 构建。我尝试在 Android Studio 中下载最旧的 NDK 版本 16，但它仍然尝试使用 clang。如何强制它使用 gcc？

版本 16 上的错误：

ERROR: /home/user/AndroidStudioProjects/opencv2builder/app/src/main/cpp/CMakeLists.txt : C/C++ debug|x86 : CMake Error at /home/user/Android/Sdk/cmake/3.10.2.4988404/share/cmake-3.10/Modules/CMakeTestCCompiler.cmake:52 (message):

    "/home/user/Android/Sdk/ndk/16.1.4479499/toolchains/llvm/prebuilt/linux-x86_64/bin/clang"

  is not able to compile a simple test program.

  It fails with the following output:
