交叉编译嵌入式openssl，关键是在config中指定编译器前缀

其实还是很顺利的。

• 下载

LINUX下载编译OpenSSL_linux下载 openssl-CSDN博客

• 编译

BUILD_LIBS=${HOME}/build_libs
 
CROSS_NAME=aarch64-mix210-linux
export PATH=/opt/linux/x86-arm/${CROSS_NAME}/bin:${PATH}
 
make clean
 
./config \
    --cross-compile-prefix=${CROSS_NAME}- \
    no-asm \
    -fPIC shared \
    --prefix=${BUILD_LIBS}  \
    --openssldir=${BUILD_LIBS}/openssl
 
# replace all -m64
sed -i 's/-m64/ /g' Makefile
 
make
 
make install
