是aubio交叉編譯的iPhone/Android/ARM？

Question

任何人都知道的：

1. 的Aubio庫爲iPhone/ARM處理器的構建？

2. 一個介紹交叉編譯資源，所以我可以自己試試嗎？

Answer 1

我已經成功交叉編譯它沒有錯誤。我沒有測試過這個庫本身，但是可執行文件的例子似乎起作用，所以這是一個好兆頭！

我放在一起的腳本（主要歸功於this link中的寶貴信息）應該適用於許多其他使用Autotools的項目（如Aubio的依賴項）。

請注意，libsndfile和libsamplerate需要一個補丁才能成功進行交叉編譯，我相信這很難看，但它很有用。

要使用它，根據您的系統修改腳本（應該是非常簡單的，我希望），下載所有的依賴項（在build xxxxx行中列出，您的版本可能會有所不同）與腳本並運行沒有參數的腳本。最後，所有內容都應位於$SYS_ROOT目錄內。

好的，主盤是以下：

Answer 2

嘗試使用第Ë最新的git：

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

Answer 3

這裏是一個構建腳本爲我工作：

#! /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 

，則默認爲工具鏈/ gcc版本4.6，我把它改爲4.9，因爲這是我最新的。 應該拉下它需要完成編譯

腳本的主要部分是好心由Aubio
