Question

目前我正在尝试交叉编译openssh。我已经编译过openssl，但是，我正在为openssh遇到麻烦。

这是构建openSSH的脚本的一部分：

export SYSROOT="$NDK_ROOT/platforms/$TARGET/arch-arm"
export CPPFLAGS="-I$NDK_ROOT/platforms/$TARGET/arch-arm/usr/include --sysroot=$SYSROOT"
export CC=$($NDK_ROOT/ndk-which gcc)
export LD=$($NDK_ROOT/ndk-which ld)
export CPP=$($NDK_ROOT/ndk-which cpp)
export CXX=$($NDK_ROOT/ndk-which g++)
export AS=$($NDK_ROOT/ndk-which as)
export AR=$($NDK_ROOT/ndk-which ar)
export RANLIB=$($NDK_ROOT/ndk-which ranlib)

export LIBS="-lssl -lcrypto -lz -ldl"
export LDFLAGS="-L$SCRIPTPATH/obj/local/armeabi"
./configure --host=arm-linux-androideabi --target=arm-linux-androideabi \
            --prefix=/data/local/tmp \
        --exec-prefix=/data/local/tmp \
            --with-ssl-dir=$SSLPATH \
            --disable-utmp \
            --disable-wtmp \
            --disable-utmpx \
            --disable-syslog \
            --without-shadow \
            --with-md5-passwords

$NDK_ROOT/ndk-build -j$JOBS -C $SCRIPTPATH openssh

lib的makefile：

SSHL_LOCAL_SRC_FILES := $(addprefix ../../openssh-portable/,$(SSHL_CSOURCES))

  $(LOCAL_PATH)/../../openssh-portable/openbsd-compat \
  $(NDK_PATH)/platforms/$(TARGET_PLATFORM)/arch-arm/usr/include \
  $(LOCAL_PATH)/../../openssl/include

我添加了之前的CFLAGS，因为我有扩展宏错误。我不确定他们！

android makefile的一部分：

#openssh
include $(LOCAL_PATH)/openssh.mk

#Static libssh
include $(CLEAR_VARS)
LOCAL_MODULE := openssh
LOCAL_SRC_FILES := $(SSL_LOCAL_SRC_FILES) $(CRYPTO_LOCAL_SRC_FILES) $(SSHL_LOCAL_SRC_FILES)
LOCAL_C_INCLUDES := $(SSL_LOCAL_C_INCLUDES) $(CRYPTO_LOCAL_C_INCLUDES) $(SSHL_LOCAL_C_INCLUDES)
LOCAL_CPPFLAGS += -std=c++11
LOCAL_CFLAGS += $(SSHL_COMMON_CFLAGS)
include $(BUILD_STATIC_LIBRARY)

我能够构建一个静态libssh.a，但是我无法为ssh程序创建可执行文件我遇到了错误：

bsd-statvfs.c:32:21: error: dereferencing pointer to incomplete type
  to->f_frsize = from->f_bsize; /* no exact equivalent */

有人已经为Android编译了openssh，这有用吗？

尝试为Android编译openssh
