为 Android 编译最新的 OpenSSL [英] Compiling the latest OpenSSL for Android
问题描述
我正在尝试为 Android 的 OpenSSL1.0.1c 的 (.so) 文件生成共享库.我发现他们在android脚本中添加了三个用于编译Android的选项.
I am trying to generate the shared library for the (.so) files of the OpenSSL1.0.1c for the Android. I found that they have added three options for compiling for the Android in the android script.
./Configure android-armv7 (or)
./Configure android-x86 (or)
./Configure android
一旦我为操作系统配置好然后尝试编译,它就会抛出错误.目前我正在使用 x86 windows7 并安装了 Cygwin、Android sdk R20、Android NDK r8
once I configured for the OS and then try to compile, its throwing errors. Currently I am working x86 windows7 and installed Cygwin, Android sdk R20, Android NDK r8
sh-4.1$ make
making all in crypto...

请让我知道是否有人遇到过类似的问题并得到了解决该问题的解决方案.
Please let me know if anyone faced the similar issue and got the solution for resolving the same.
推荐答案
我真的不建议从官方 OpenSSL 网站之外获取任何内容.在处理密码学和安全性方面,您不能冒险.
I would seriously not advise to grab anything outside of the official OpenSSL web site. You cannot take a chance when dealing with cryptography and security.
我看到的唯一问题是您使用的是主机的 gcc 而不是 android 的交叉编译器.
The only problem that I see is that you are using your host's gcc rather than using android's cross compilers.
这是我在 Ubuntu 14.04LTS 上编译官方 OpenSSL 的方法(这适用于 OpenSSL 1.0.1g)
Here is how I would compile the official OpenSSL on Ubuntu 14.04LTS (this works with OpenSSL 1.0.1g)
从您的主文件夹,运行以下命令:
From your home folder, run the following commands:
tar xzvf ~/Downloads/openssl-1.0.1g.tar.gz
cd openssl-1.0.1g
export NDK=~/android-ndk-r9d
$NDK/build/tools/make-standalone-toolchain.sh --platform=android-9 --toolchain=arm-linux-androideabi-4.6 --install-dir=`pwd`/android-toolchain-arm
export TOOLCHAIN_PATH=`pwd`/android-toolchain-arm/bin
export TOOL=arm-linux-androideabi
export NDK_TOOLCHAIN_BASENAME=${TOOLCHAIN_PATH}/${TOOL}
export CC=$NDK_TOOLCHAIN_BASENAME-gcc
export CXX=$NDK_TOOLCHAIN_BASENAME-g++
export LINK=${CXX}
export LD=$NDK_TOOLCHAIN_BASENAME-ld
export AR=$NDK_TOOLCHAIN_BASENAME-ar
export RANLIB=$NDK_TOOLCHAIN_BASENAME-ranlib
export STRIP=$NDK_TOOLCHAIN_BASENAME-strip
export ARCH_FLAGS="-march=armv7-a -mfloat-abi=softfp -mfpu=vfpv3-d16"
export ARCH_LINK="-march=armv7-a -Wl,--fix-cortex-a8"
export CPPFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export CXXFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 -frtti -fexceptions "
export CFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export LDFLAGS=" ${ARCH_LINK} "
然后运行你的配置脚本:
And then run your configure script:
./Configure android-armv7
然后构建
PATH=$TOOLCHAIN_PATH:$PATH make
您应该看到它使用的是 arm-linux-androideabi-gcc
而不是 gcc
You should see that it is using arm-linux-androideabi-gcc
instead of gcc
为旧的 armeabi 构建:
To build for the old armeabi:
tar xzvf ~/Downloads/openssl-1.0.1g.tar.gz
cd openssl-1.0.1g
export NDK=~/android-ndk-r9d
$NDK/build/tools/make-standalone-toolchain.sh --platform=android-9 --toolchain=arm-linux-androideabi-4.6 --install-dir=`pwd`/android-toolchain-arm
export TOOLCHAIN_PATH=`pwd`/android-toolchain-arm/bin
export TOOL=arm-linux-androideabi
export NDK_TOOLCHAIN_BASENAME=${TOOLCHAIN_PATH}/${TOOL}
export CC=$NDK_TOOLCHAIN_BASENAME-gcc
export CXX=$NDK_TOOLCHAIN_BASENAME-g++
export LINK=${CXX}
export LD=$NDK_TOOLCHAIN_BASENAME-ld
export AR=$NDK_TOOLCHAIN_BASENAME-ar
export RANLIB=$NDK_TOOLCHAIN_BASENAME-ranlib
export STRIP=$NDK_TOOLCHAIN_BASENAME-strip
export ARCH_FLAGS="-mthumb"
export ARCH_LINK=
export CPPFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export CXXFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 -frtti -fexceptions "
export CFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export LDFLAGS=" ${ARCH_LINK} "
./Configure android
make clean
PATH=$TOOLCHAIN_PATH:$PATH make
为 x86 构建:
tar xzvf ~/Downloads/openssl-1.0.1g.tar.gz
cd openssl-1.0.1g
export NDK=~/android-ndk-r9d
$NDK/build/tools/make-standalone-toolchain.sh --platform=android-9 --toolchain=x86-4.6 --install-dir=`pwd`/android-toolchain-x86
export TOOLCHAIN_PATH=`pwd`/android-toolchain-x86/bin
export TOOL=i686-linux-android
export NDK_TOOLCHAIN_BASENAME=${TOOLCHAIN_PATH}/${TOOL}
export CC=$NDK_TOOLCHAIN_BASENAME-gcc
export CXX=$NDK_TOOLCHAIN_BASENAME-g++
export LINK=${CXX}
export LD=$NDK_TOOLCHAIN_BASENAME-ld
export AR=$NDK_TOOLCHAIN_BASENAME-ar
export RANLIB=$NDK_TOOLCHAIN_BASENAME-ranlib
export STRIP=$NDK_TOOLCHAIN_BASENAME-strip
export ARCH_FLAGS="-march=i686 -msse3 -mstackrealign -mfpmath=sse"
export ARCH_LINK=
export CPPFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export CXXFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 -frtti -fexceptions "
export CFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export LDFLAGS=" ${ARCH_LINK} "
./Configure android-x86
make clean
PATH=$TOOLCHAIN_PATH:$PATH make
