AndroidのOpenSSHのクロスコンパイル
Androidに基づいて Stack Overflowでのこの回答 ）のOpenSSHのコンパイルに取り組んでいます。
これが私がこれまでにしたことです：
- Ubuntu 14.04AMD64でのビルド。
apt-get install build-essential gcc-arm-linux-androideabi
Zlibをダウンロードして、次の手順を実行します。
cd zlib-1.2.8
./configure --prefix=/vagrant/build
make CC=arm-linux-androideabi-gcc
make install
これはmakeステップで失敗します。
gcc -shared -Wl,-soname,libz.so.1,--version-script,zlib.map -O3 -fPIC -D_LARGEFILE64_SOURCE=1 -DHAVE_HIDDEN -o libz.so.1.2.8 adler32.lo crc32.lo deflate.lo infback.lo inffast.lo inflate.lo inftrees.lo trees.lo zutil.lo compress.lo uncompr.lo gzclose.lo gzlib.lo gzread.lo gzwrite.lo -lc
/usr/bin/ld: crc32.lo: Relocations in generic ELF (EM: 40)
crc32.lo: error adding symbols: File in wrong format
collect2: error: ld returned 1 exit status
make: *** [libz.so.1.2.8] Error 1
ここで何が欠けていますか？ zlibをビルドできるようにするために知っておく必要のあることは他にありますか？
次のプロセスは、OpenSSLを構築することです。
cd openssl-1.0.1h/
./Configure dist --prefix=/vagrant/build/
make CC="arm-linux-androideabi-gcc" AR="arm-linux-androideabi-ar r" RANLIB="arm-linux-androideabi-ranlib"
make install
これもmakeステップで失敗します。

make[1]: *** [openssl] Error 2
make[1]: Leaving directory `/vagrant/openssl-1.0.1h/apps'
make: *** [build_apps] Error 1
繰り返しますが、同じ問題が発生しているようで、書き込んだファイルを読み取ることができません。
私はまだOpenSSHをコンパイルする最終ステップに到達していませんが、これは私がそれを行うと私が想定している方法です。
cd openssh-6.6p1
./configure --Host=arm-linux --with-libs --with-zlib=$HOME/zlibArm --with-ssl-dir=$HOME/opensslArm --disable-etc-default-login CC=gcc-arm-linux-gnueabi-gcc AR=gcc-arm-linux-gnueabi-ar
make
arm-linux-androideabiでコンパイルするときに、上記のコンパイルがZlibとOpenSSLで失敗するのはなぜですか？ ARMでAndroid）用にOpenSSH（特にクライアントとエージェント）をコンパイルするにはどうすればよいですか？
ビルドが失敗する理由は、Makeがプラットフォームのリンカー（/ usr/bin/ld）を使用して、arm-linux-androideabi-gccが生成するオブジェクトファイルをリンクしているためです。正しいツールを探すようにconfigureに指示してから、コンパイルを再試行する必要があります。また、Android NDKをどこかにインストールし、NDK_ROOTをその場所にポイントする必要があります。これはAndroidターゲット用にプログラムをコンパイルするために使用する小さなスクリプトです。 。
これはかなり遅い応答だと思いますが、とにかく誰かに役立つことを願っています。
