适用于Android x86_64和mips64的Openssl

我为5/7的android-21(android-L)架构构建了openssl:armeabi,armeabi-v7a,arm64,mips,x86。但是我无法为x86_64和mips64构建它。

我在做什么......

x86 - 正在工作

以下是我的x86工作脚本,使用make-standalone-toolchain创建的工具链:

export ANDROID_NDK_ROOT=/Users/jacsteve/dev/android/ndk
export ANDROID_API=android-21
export ANDROID_ARCH=arch-x86
export ANDROID_EABI=i686-linux-android-4.9
export ANDROID_SYSROOT=$ANDROID_NDK_ROOT/platforms/$ANDROID_API/arch-x86
export ANDROID_TOOLCHAIN=/tmp/toolchain/x86
export ANDROID_DEV=$ANDROID_SYSROOT/usr

export SYSTEM=android
export ARCH=x86

export CROSS_COMPILE=i686-linux-android-

export CFLAGS="--sysroot=$ANDROID_SYSROOT"
export CPPFLAGS="--sysroot=$ANDROID_SYSROOT"
export CXXFLAGS="--sysroot=$ANDROID_SYSROOT"

./Configure android-x86 shared no-asm -no-ssl2 -no-ssl3 -no-comp -no-hw --cross-compile-prefix=$CROSS_COMPILE --openssldir=/tmp/ssl/x86

make depend
make
make install

这很好用,libssl.so

让我libcrypto.so/tmp/ssl/x86

x86_64 - 失败

然而,x86_64失败了。这是脚本:

export ANDROID_NDK_ROOT=/Users/jacsteve/dev/android/ndk
export ANDROID_API=android-21
export ANDROID_ARCH=arch-x86_64
export ANDROID_EABI=x86_64-linux-android-4.9
export ANDROID_SYSROOT=$ANDROID_NDK_ROOT/platforms/$ANDROID_API/arch-x86_64
export ANDROID_TOOLCHAIN=/tmp/toolchain/x86_64
export ANDROID_DEV=$ANDROID_SYSROOT/usr

export SYSTEM=android
export ARCH=x86_64

export CROSS_COMPILE=x86_64-linux-android-

export CFLAGS="--sysroot=$ANDROID_SYSROOT"
export CPPFLAGS="--sysroot=$ANDROID_SYSROOT"
export CXXFLAGS="--sysroot=$ANDROID_SYSROOT"

./Configure android-x86 shared no-asm -m64 -no-ssl2 -no-ssl3 -no-comp -no-hw --cross-compile-prefix=$CROSS_COMPILE --openssldir=/tmp/ssl/x86_64

make depend
make
make install

错误......

x86_64的

我收到来自make调用的大量错误消息,如下所示:

/private/tmp/toolchain/x86_64/bin/../lib/gcc/x86_64-linux-android/4.9/../../../../x86_64-linux-android/bin/ld:
error: libcrypto.a(cryptlib.o): incompatible target
/private/tmp/toolchain/x86_64/bin/../lib/gcc/x86_64-linux-android/4.9/../../../../x86_64-linux-android/bin/ld:
error: libcrypto.a(mem.o): incompatible target
...
collect2: error: ld returned 1 exit status

我认为x86_64-linux-android-gcc正在编译所有内容,但是当我们进入链接阶段时,x86_64-linux-android-ld无法读取已编译的目标文件。

MIPS64

对mips64使用类似的设置(使用./Configure android-mips ...)我收到以下错误,这与mips64-linux-android-ld无法读取目标文件的问题类似:

/Users/jacsteve/dev/android/ndk/platforms/android-21/arch-mips64/usr/lib/libdl.so: error adding symbols: File in wrong format
collect2: error: ld returned 1 exit status

有谁知道如何成功构建x86_64和mips64架构?

3 个答案:

答案 0 :(得分:3)

解决!

而不是

./Configure android-x86 ...

我用过

./Configure linux-generic64 ...

我还将linux-generic32用于32位架构。

答案 1 :(得分:1)

在./Configure之前运行make clean为我解决了问题。

答案 2 :(得分:0)

我认为构建openssl for mips64的错误是由于对象和库之间的ABI格式不兼容,格式对象是mips-ELF64,而ANDROID_NDK提供的库是mips ELF32
