Thanks for your reply.
1) The main.c line 39 is:
transend(protablebuf,"192.168.1.101",1111);
where the protablebuf is a pointer to a struct ProperTable
struct ProperTable
{
u1byte Type;
u2byte UserID;
u2byte PID;
u2byte Lenth;
char Data[1024];
};
2) The program works on X86, such as Linux in Vmware.
3) The program crash on the first call to transcend.
4) The demo ssl in openssl directory also crash.
Reload the question:
Problem of OpenSSL on MIPS R3000
I just cross compile the OpenSSL 0.9.7 under linux by mipsel-linux-gcc for
MIPS R3000, no error occur during the compiling process.
But, when I put the result lib to the hard platform, the openssl routines
can not be carried out and “segment fault” occurs.
Why? Does the OpenSSL not support the MIPS? How should I do to cross compile
for MIPS R3000?
