Embedding binary blobs using gcc mingw
- by myforwik
I am trying to embed binary blobs into an exe file. I am using mingw gcc.
I make the object file like this:
ld -r -b binary -o binary.o input.txt
I then look objdump output to get the symbols:
objdump -x binary.o
And it gives symbols named:
_binary_input_txt_start
_binary_input_txt_end
_binary_input_txt_size
I then try and access them in my C program:
#include <stdlib.h>
#include <stdio.h>
extern char _binary_input_txt_start[];
int main (int argc, char *argv[])
{
char *p;
p = _binary_input_txt_start;
return 0;
}
Then I compile like this:
gcc -o test.exe test.c binary.o
But I always get:
undefined reference to _binary_input_txt_start
Does anyone know what I am doing wrong?
