【问题描述】：

任何人都知道：

为 iPhone/ARM 处理器构建的 Aubio 库？

交叉编译简介资源，我可以自己尝试一下吗？

【参考方案1】：

尝试使用最新的 git：

$ git clone git://git.aubio.org/git/aubio
$ cd aubio/
$ ./waf configure build --with-target-platform ios

【参考方案2】：

我已经成功地交叉编译它而没有错误。我还没有测试库本身，但是示例可执行文件似乎可以工作，所以这是一个好兆头！

我编写的脚本（很大程度上感谢 this link 中的宝贵信息）应该适用于许多其他使用 Autotools 的项目（如 Aubio 的依赖项）。

请注意，libsndfile 和 libsamplerate 都需要一个补丁才能成功交叉编译，我敢肯定这很难看，但它可以工作。

要使用它，请根据您的系统修改脚本（应该很简单，我希望），下载所有依赖项（在末尾的build xxxxx 行中列出，您的版本可能会有所不同）在同一目录中脚本并运行不带参数的脚本。最后，所有内容都应该在$SYS_ROOT 目录中。

好的，下面是主菜：

【参考方案3】：

这是一个对我有用的构建脚本：

#! /bin/sh

"""
build the toold chain home with:
build/tools/make-standalone-toolchain.sh --platform=android-9 --install-dir=../android-9-toolchain
"""

NDK_HOME=~/dev/SDKs/android-9-toolchain
set -x
set -e
export CC=$NDK_HOME/bin/arm-linux-androideabi-gcc
export CFLAGS=-I$NDK_HOME/include
export LDFLAGS="-L$NDK_HOME/lib"
export AR=$NDK_HOME/bin/arm-linux-androideabi-ar

./waf distclean
./waf configure --with-target-platform android --disable-jack
./waf build --verbose
./waf install --destdir dist-android

它将默认为 toolchain / gcc 版本 4.6，我将其更改为 4.9，因为这是我拥有的最新版本。 它应该拉下完成编译所需的库
