First, .h file may contain more information than just function prototypes.
So unless you want to drop some features, to truly eliminate the need of
two files while retain all features you would end up either:
- * embed everything into the new object format
- * just zip/pack the .obj with .h, like how mac handle application bundles
If you only want function prototypes, you can do this:
Code: Select all
$ cat abc.cpp
int adder(int a, int b){
return a+b;
}
$ objdump -t a.o
a.o: file format elf32-i386-freebsd
SYMBOL TABLE:
00000000 l df *ABS* 00000000 a.cpp
00000000 l d .text 00000000
00000000 l d .data 00000000
00000000 l d .bss 00000000
00000000 l d .comment 00000000
00000000 g F .text 0000000b _Z5adderii
00000000 *UND* 00000000 __gxx_personality_v0
It should be possible to generate function prototypes from "_Z5adderii" on-the-fly.

I can, with a stock binutils and a yasm, read and modify configurations embedded into the binary. It will work on linux, bsd, and my OS alike, as well as any x86-based platform as the method requires absolutely no additional logic on the host side. It will work the same on any other non-x86 ELF-based platform, it only requires binutils and an added tool that does bin2obj functionality and adding some addresses.
That solves your problem as described. If it still isn't a valid answer, your problem description was inadequate and you need to provide additional arguments.

"file format for the sake of file format"
for me, reinventing the wheel is fun.....

It is certainly fun when you're 14. I also invented a few file formats at that time.
I have already 2 (perhaps more, but these I remember): one is
.gear and the other one is
.aze.
Just some text formats with a syntax of their own. This is to show that [a-f]yo kids like and will reinvent wheels, will over-think things in the most absurd ways, and will remain kids, with everything that implies (making fool of yourself, crying over stupid stuff etc.).
