| | === Android NDK 交叉编译 === |
| | * 官方文档参考这个链接 https://docs.conan.io/en/latest/integrations/cross_platform/android.html， 而不是这个链接<del>https://docs.conan.io/en/latest/systems_cross_building/cross_building.html</del>， 后者的示例在 armv8 会错误编译成 armv7。 |
| | * 可直接使用官方[[https://docs.conan.io/en/latest/integrations/cross_platform/android.html|这个链接]]的第一种办法，即在 profile 里直接使用 ''android-ndk''包作为 tool_requires, 比如编译 armv8:<code ini>include(default) |
| | [settings] |
| | arch=armv8 |
| | build_type=Release |
| | compiler=clang |
| | compiler.libcxx=libc++ |
| | compiler.version=11 |
| | os=Android |
| | os.api_level=21 |
| | [tool_requires] |
| | android-ndk/r22b |
| | [options] |
| | [env]</code> 然后install 或 create 时指定跨平台编译 <code bash>conan install .. --build=missing -pr:h android-armv8 -pr:b default</code> |
| | * [[https://docs.conan.io/en/latest/systems_cross_building/cross_building.html|这个链接里android 示例]] 错误的原因是， Android 与 CMake 结合时， CMake 除了指定 android.toolchain.cmake, 还需要额外[[https://developer.android.com/ndk/guides/cmake#variables|指定变量]] ''ANDROID_ABI'' ''ANDROID_PLATFORM'' 才能正确编译出目标版本。 而 conan 并[[https://docs.conan.io/en/latest/reference/env_vars.html|没有办法在 profile 里直接设置]]这两个 cmake 变量, 所以就算你的工程的 CMakefile.txt 设置了这两变量，你的依赖包在cmake building 时也会默认选择了错误的arch。 |
