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

Try using the latest git:

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

哥，最终变帅啦 2024-12-02 20:15:54

我已经成功地交叉编译了它，没有错误。我还没有测试该库本身，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（很大程度上要感谢 此链接）应该适用于许多使用 Autotools 的其他项目（例如 Aubio 的依赖项）。

请注意，libsndfile 和 libsamplerate 都需要补丁才能成功交叉编译，我确信这很丑陋，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），下载所有依赖项（在最后的 build xxxxx 行中列出，您的版本可能会有所不同）与脚本相同的目录并运行不带参数的脚本。最后，所有内容都应该位于 $SYS_ROOT 目录中。

好了，主菜如下：

I've succeeded in cross-compiling it without errors. I haven't tested the library itself, but the example executables seem to work, so that's a good sign!

The script I've put together (largely thanks to the invaluable information in this link) should work for a lot of other projects using Autotools (like Aubio's dependencies).

Note that both libsndfile and libsamplerate need a patch to cross-compile successfully, which I'm sure is ugly, but it works.

To use it, modify the script according to your system (should be pretty straightforward, I hope), download all the dependencies (listed in the build xxxxx lines at the end, your versions may vary) in the same directory as the script and run the script without arguments. At the end, everything should be inside the $SYS_ROOT directory.

Okay, the main dish is below :

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

它将默认为工具链/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。
它应该下拉完成编译脚本主要部分所需的库，

由 Aubio 的作者 Paul Brossier 友情提供

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
