centos下国密 SSL的gmssl编译
按照官网http://gmssl.org/docs/install.html的提示直接编译：
wget https://github.com/guanzhi/GmSSL/archive/master.zip
./config
make
make test
sudo make install
然后尝试执行gmssl，报错：
~/GmSSL-master$ gmssl
gmssl: relocation error: gmssl: symbol BIO_debug_callback version OPENSSL_1_1_0d not defined in file libcrypto.so.1.1 with link time reference
执行查看gmssl依赖库路径：
root@master:/home/master/GmSSL-master# ldd /usr/local/bin/gmssl
linux-vdso.so.1 => (0x00007ffc235f4000)
libssl.so.1.1 => /usr/local/openssl/lib/libssl.so.1.1 (0x00007f50a3afc000)--这里一定注意路径是在哪
libcrypto.so.1.1 => /usr/local/openssl/lib/libcrypto.so.1.1 (0x00007f50a35a80--同上需要覆盖2个文件
libdl.so.2 => /lib64/libdl.so.2 (0x00007f50a33a4000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f50a3188000)
libc.so.6 => /lib64/libc.so.6 (0x00007f50a2dba000)
libz.so.1 => /lib64/libz.so.1 (0x00007f50a2ba4000)
/lib64/ld-linux-x86-64.so.2 (0x00007f50a3d6b000)
把make得到的两个依赖库拷贝到相应路径：
root@master:~# cd /root/master/GmSSL-master/
root@master:/root/master/GmSSL-master# ls
apps build.info CODE_OF_CONDUCT.md config.com Configurations crypto demos engines external go java libcrypto.a libcrypto.so libssl.a libssl.so LICENSE Makefile.shared openssl.pc php README.md ssl.map tools VMS
appveyor.yml certs config configdata.pm Configure crypto.map doc e_os.h fuzz include js libcrypto.pc libcrypto.so.1.1 libssl.pc libssl.so.1.1 Makefile ms os-dep pod2htmd.tmp ssl test util
root@master:/root/master/GmSSL-master# cp libcrypto.so.1.1 /usr/local/openssl/lib/--这里注意要与你之前依赖路径一样
root@master:/root/master/GmSSL-master# cp libssl.so.1.1 usr/local/openssl/lib/--同上记住是2个文件要同时覆盖
