Hi, everyone,
An urgent problem:
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?
The program works on X86, such as Linux in Vmware. The program crash on the
first call to transcend. The demo ssl in openssl directory also crash.
How should I do to cross compile for MIPS R3000? Some info The debug info
during the process is :

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];
};

The OpenSSL Cross-Compile Configure process:
Edit the Configure file of OpenSSL source code file package.
Add the following variable to “my %table”:
"linux-mipsel", "mipsel-linux-gcc:-mtune=r3000 -mips2 -DTERMIO -O3
-fomit-frame-pointer
-Wall::-D_REENTRANT::-ldl::${no_asm}:dlfcn:linux-shared:-fPIC::.so.\$(SHLIB_
MAJOR).\$(SHLIB_MINOR)",
Save the Configure file, then execute the following command:
./Configure linux-mipsel no-asm --prefix=/tmp
make
make install
cp -a --reply=yes openssl/ /home/tjy/sunplus/sp1000/mipsel-linux/include/
