Compiling OpenSSL for gp2x Wiz

The GP2X Wiz handheld game machine linux based

For compile OpenSSL in Cross compiler with GPESDK for ARM cpu do this:

Download the GP2X OpenWIZ SDK or Download the GP2X WIZ SDK official of GamePark Holdings (recommended)
Download OpenSSL from sources

unpack all two, and go to OpenSSL source code path


./config no-asm --openssldir=/opt/GPH_SDK --prefix=/opt/GPH_SDK
After this step, edit Makefile to use the GP2X SDK cross compiler
Replace tis three values with path and binary of cross compiler, in my case:

CC= /opt/GPH_SDK/tools/gcc-4.0.2-glibc-2.3.6/arm-linux/bin/arm-linux-gcc
AR= /opt/GPH_SDK/tools/gcc-4.0.2-glibc-2.3.6/arm-linux/bin/arm-linux-ar $(ARFLAGS) r
RANLIB= /opt/GPH_SDK/tools/gcc-4.0.2-glibc-2.3.6/arm-linux/bin/arm-linux-ranlib
Compile and enjoy with OpenSSL libraries for your GP2X Wiz (and make software for them!)


The following code is suitable for testing library on GP2X Wiz:
#include "/opt/arm-openwiz-linux-gnu/include/openssl/md5.h"
#include <stdlib.h>
#include <stdio.h>

int main(int argc, char *argv[])
 const unsigned char * originalText = (unsigned char *)"Hello world";
 unsigned char * outputBuffer = malloc(4096);
 unsigned long originalTextLen = 11;
 int len;

 MD5( originalText, originalTextLen, outputBuffer);
 for (len=0;len<=15; len++)
  printf("%02x", outputBuffer[len]);
Remember compile them with:
/opt/GPH_SDK/tools/gcc-4.0.2-glibc-2.3.6/arm-linux/bin/arm-linux-gcc main.c -o testOpenSSLarm -lcrypto -L /opt/GPH_SDK/lib -I /opt/GPH_SDK/include -static
