一、系统环境
操作系统：centos6.4 x86_64
openssl版本：openssl-0.9.8e
二、安装过程
# tar zxvf openssl-0.9.8e.tar.gz # cd openssl-0.9.8e # ./config shared zlib # make
报错：
md5-x86_64.s:41: Error: 0xd76aa478 out range of signed 32bit displacement md5-x86_64.s:50: Error: 0xe8c7b756 out range of signed 32bit displacement md5-x86_64.s:68: Error: 0xc1bdceee out range of signed 32bit displacement md5-x86_64.s:77: Error: 0xf57c0faf out range of signed 32bit displacement md5-x86_64.s:95: Error: 0xa8304613 out range of signed 32bit displacementMany more errors like this.
解决方法：
#vim openssl-0.9.8e/crypto/md5/asm/md5-x86_64.pl
在
sub round1_step
{ my ($pos, $dst, $x, $y, $z, $k_next, $T_i, $s) = @_;
后面加入：
+ $T_i = unpack("l",pack("l", hex($T_i))); # convert to 32-bit signed decimal
类似地，在sub round2_step, sub round3_step 和 sub round4_step相应的位置都加上这行
重新编译安装，成功！
