與Android NDK交叉編譯全單聲道

Question

我試圖編譯完全單聲道運行在（根）Android設備上。我需要這個，因爲我想將應用程序從嵌入式Linux移植到Android。該軟件目前嵌入式Linux設備上運行...我真的想重用的軟件，因爲它是無需重寫它的部分......

什麼我迄今所做的：

-Installed在Linux的Debian

-Installed Android SDK中NDK作爲http://developer.android.com/ndk/guides/index.html

-Downloaded的MONO壓縮包（我已經嘗試不同的版本4.6，4.8和5.0）

-run以下命令：

export CC=/home/alex/Android/mytoolchain/bin/arm-linux-androideabi-gcc 
export CXX=/home/alex/Android/mytoolchain/bin/arm-linux-androideabi-g++ 
export CPP=/home/alex/Android/mytoolchain/bin/arm-linux-androideabi-cpp 
export AR=/home/alex/Android/mytoolchain/bin/arm-linux-androideabi-ar 
export AS=/home/alex/Android/mytoolchain/bin/arm-linux-androideabi-as 
export ANDROID_STANDALONE_TOOLCHAIN=/home/alex/Android/mytoolchain 

./configure --prefix=/home/alex/Android/monobuild/ --with-sigaltstack=no --with-mcs-docs=no --disable-mcs-build --host=arm-linux-androideabi --target=arm-linux-androideabi --disable-nls --with-sysroot=/home/alex/Android/mytoolchain/sysroot/ --cache=/home/alex/Android/my.cache 

make

在mono配置腳本中，我看到了很多關於Android的東西，所以我認爲它必須可以交叉編譯。誰知道有關錯誤的更多細節？

我可以從NDK目錄複製文件math_private.h到單目錄，但後來它打破在稍後階段：

保存自己的一些麻煩和使用standalone toolchain。它會照顧使用autoconf與NDK的頭痛問題。
