任何人都知道：
iPhone/ARM 处理器的Aubio库的构建？
一个介绍交叉编译的资源，所以我可以自己尝试一下？

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

Here is a build script that worked for me:
#! /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
it will default to toolchain / gcc version 4.6, I changed this to 4.9 as that is the latest I have. it should pull down the libraries it needs to finish compiling
the main part of the script was kindly provided by Paul Brossier author of Aubio

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，但示例可执行文件似乎可以工作，所以这是一个好兆头！
我整理的脚本（很大程度上感谢此链接中的宝贵信息）应该适用于许多其他使用 Autotools 的项目（如 Aubio 的依赖项）。
请注意，两者都libsndfile需要libsamplerate一个补丁才能成功交叉编译，我敢肯定这很丑陋，但它确实有效。
要使用它，请根据您的系统修改脚本（我希望应该非常简单），将所有依赖项（在最后build xxxxx几行中列出，您的版本可能会有所不同）下载到与脚本相同的目录并运行脚本没有论据。最后，一切都应该在$SYS_ROOT目录中。
好的，主菜如下：
