添加 Android 项目需要的 CFLAGS 的技巧

当 configure 不支持某个参数时，需要主动在 CFLAGS 中添加。

1、新建 Android 的 C++ 项目

2、build release 版本，生成 build.ninja、rules.ninja

3、使用 build.ninja 中的 FLAGS

-g -DANDROID -fdata-sections -ffunction-sections -funwind-tables -fstack-protector-strong -no-canonical-prefixes -D_FORTIFY_SOURCE=2 -march=armv7-a -mthumb -Wformat -Werror=format-security   -Oz -DNDEBUG  -fPIC

4、使用 rules.ninja 中的参数

--target=armv7-none-linux-androideabi21 --gcc-toolchain=/home/weichao/android-sdk/ndk/21.3.6528147/toolchains/llvm/prebuilt/linux-x86_64 --sysroot=/home/weichao/android-sdk/ndk/21.3.6528147/toolchains/llvm/prebuilt/linux-x86_64/sysroot

调整路径，修改参数，去掉重复的参数：

1	`--target=armv7-none-linux-androideabi21 --gcc-toolchain=/home/weichao/android-ndk-r21d/toolchains/llvm/prebuilt/linux-x86_64`

编译生成 Android 所需的库

给脚本文件设置权限

1	`chmod +x build.sh`

执行脚本文件

1	`. build.sh`

编译过程

先打印信息概览：

编译完成后生成文件：

编译和使用时可能会遇到的问题

not found

1、WARNING: /home/weichao/android-ndk-r21d/toolchains/llvm/prebuilt/linux-x86_64/bin/arm-linux-androideabi-pkg-config not found, library detection may fail.

未发现有什么影响。

2、java.lang.UnsatisfiedLinkError: dlopen failed: library “libclang_rt.ubsan_standalone-aarch64-android.so” not found

查看 log.txt，有相关信息：

liblog.so 是在：/home/weichao/android-ndk-r21d/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/aarch64-linux-android/21/liblog.so

2.1、（失败）按照 clang 的建议，启用 rpath，并设置 ldflags：

1	`EXTRA_LDFLAGS="-Wl,-rpath=/home/weichao/android-ndk-r21d/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/aarch64-linux-android/21"`

同时尝试修改 CMakeLists.txt：

修改方式 1

1
2

add_library(lib_log SHARED IMPORTED)
set_target_properties(lib_log PROPERTIES IMPORTED_LOCATION /home/weichao/android-ndk-r21d/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/aarch64-linux-android/21/liblog.so)

修改方式 2

1 2	`set(CMAKE_BUILD_WITH_INSTALL_RPATH TRUE) set(CMAKE_INSTALL_RPATH "/home/weichao/android-ndk-r21d/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/aarch64-linux-android/21")`

这样是在 log.txt 中没有报错了，但是在 Android 中依然报错，原因可能是在 CMakeLists.txt 中的修改方式不对，没有链接上。

2.2、找出是哪个配置导致的这个问题：

–toolchain=clang-usan
直接去掉这个配置就可以了。

unable to create an executable file

1、/home/weichao/android-ndk-r21d/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang is unable to create an executable file.
C compiler test failed.

没有信息概览，很明显编译失败了。

查看 log.txt，是 CPU 的值设置错误：

arm64-v8a 的 CPU 的值应该为 armv8-a，修改后：

dlopen failed

1、java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol “ff_parse_a53_cc” referenced by “/data/app/io.weichao.bwk-D1NGyDX98F4V4LoBM5Qlvg==/lib/arm64/libavcodec.so”…

–disable-everything
很明显是裁减导致的库没有加入 libavcodec.so，关闭 disable everything，验证可以解决这个问题。

应该是播放 MP4 文件时缺少解封装、解码器等，由于功能还在增加中，暂时先关闭 disable everything，以解决这个问题。
