Which program creates a C array given any file?

Question

I remember seeing in the past a program that would take any file and generate a C array representing that file as output; it would prevent distribution of a separate file in

Answer 1

For large files, converting to text and then making the compiler parse it all over again is inefficient and unnecessary. Use objcopy instead:

objcopy -I binary -O elf32-i386 stuff stuff.o

(Adjust the output architecture as necessary for non-x86 platforms.) Then once you link it into your program, you can access it like so:

extern char _binary_stuff_start[], _binary_stuff_end[];
#define SIZE_OF_STUFF (_binary_stuff_end - _binary_stuff_start)

...

foo(_binary_stuff_start[i]);
