Hello Sir, I have been able to make the DISC code compatible with openser-1.1.1-notls. I have eliminated some of the bugs which were there in the source code of DISC.But the thing is that the disc code is not able to work with x86_64 architecture. But it is successfully running with i386 arch. Could u please suggest me the neccessary task,i have to perform in order to make DISC compiled on x86_64 arch. I tried taking the successfully running code from i386 arch and copying it on x86_64 arch and then to compile it, but it is giving some architecture compilation problem which is given below.
