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

• 检查编译结果

  check file

  echo
  for so_file in libcrypto.so.1.1
  libssl.so.1.1
  do
  so_file={BUILD_LIBS}/lib/{so_file}
  file ${so_file}
  done
