CentOS 6.02 64位操作系统中的OpenSSL构建错误

Question

I am facing some problems in building openssl in CentOS 6.02 64 bit OS. Whenever I try to build it I face the errors followings:-

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 displacement
Many more errors like this.

Answer 1

It's a problem with the addressing in the assembly code. (32 bit vs 64 bit addressing.) There was a bug filed for this.

For a quick fix try recompiling with the no-asm option.

cd <openssl-source-directory>
./config no-asm
make && make install

EDIT: To resolve the errors caused by not having the -fPIC flag: do a make clean , change the line for ./config no-asm to ./config no-asm -fPIC , and run make && make install .

Answer 2

Open the file 'openssl-x/crypto/md5/asm/md5-x86_64.pl'

Then make the following changes:

After:

sub round1_step

{ my ($pos, $dst, $x, $y, $z, $k_next, $T_i, $s) = @_;

Add the following line:

+ $T_i = unpack("l",pack("l", hex($T_i))); # convert to 32-bit signed decimal

Similarly, add the same line for sub round2_step, sub round3_step & sub round4_step
