Hi Peter,
Please find the below source code built for shared executable.
Toolchain used: stbgcc-4.5.4-2.9.tar.bz
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/mman.h>
#include <errno.h>
#include <sys/stat.h>
#include <fcntl.h>
#define BDBG_UINT64_ARG(x) (unsigned )((x)>>32), (unsigned )(x)
#define BDBG_UINT64_FMT "0x%x%08x"
int main()
{
void *addr;
unsigned length=157286400;
unsigned long long offset=0x0c0200000;
int fd=open("/tmp/1.txt", O_RDWR | O_CREAT | O_TRUNC);
addr = mmap(0, length, PROT_READ|PROT_WRITE, MAP_SHARED, fd, offset);
if (addr == MAP_FAILED)
{
printf("ERROR:mmap failed: offset " BDBG_UINT64_FMT ", size=%u,
errno=%d\n",
BDBG_UINT64_ARG(offset), (unsigned)length, errno);
addr = NULL;
}
else
{
printf("SUCCESS:mmap offset:" BDBG_UINT64_FMT " size:%u ->
%p\n",
BDBG_UINT64_ARG(offset), (unsigned)length, addr);
}
return 0;
}
Compile using mips-cc with mentioned options:
<ToolChainPath>/stbgcc-4.5.4-2.9/bin//mipsel-linux-uclibc-gcc -o mmap_krish
mmap.c -finline-limit=300 -fPIC -D_GNU_SOURCE=1 -D_FILE_OFFSET_BITS=64
-fstack-protector-all -D_FORTIFY_SOURCE=2 -D_LARGEFILE_SOURCE
-D_LARGEFILE64_SOURCE -DBSTD_CPU_ENDIAN=BSTD_ENDIAN_LITTLE
