openssl ,msys2 ,交叉编译

1.下载openssl 解包

2.配置检查编译工具，类似 E:/qtBuild/build/gcc-linaro-6.3.1-2017.02-i686-mingw32_aarch64-linux-gnu/bin/aarch64-linux-gnu- ，注意""-"，是必须的，是工具链的前缀

3.构建配置指令

./Configure linux-aarch64 no-asm CROSS_COMPILE="E:/qtBuild/build/gcc-linaro-6.3.1-2017.02-i686-mingw32_aarch64-linux-gnu/bin/aarch64-linux-gnu-" --prefix=/openssl-arm

4.配置完成输出：

dell@DESKTOP-O2I5P43 MINGW64 /c/Users/dell/Downloads/openssl-OpenSSL_1_1_1/openssl-OpenSSL_1_1_1
$ ./Configure linux-aarch64 no-asm CROSS_COMPILE="E:/qtBuild/build/gcc-linaro-6.3.1-2017.02-i686-mingw32_aarch64-linux-gnu/bin/aarch64-linux-gnu-" --prefix=/openssl-arm
Configuring OpenSSL version 1.1.1 (0x1010100fL) for linux-aarch64

5. make install 安装
