Adding text files to binaries with objcopy, but objcopy complains about architecture

Question

I've read about embedding text files (or any other resource for that matter) into binaries, and I'm doing it like so:

objcopy -I binary -O elf32-littlearm --binary-architecture arm myfile.txt myfile.txt.o

However, unlike in the tutorial, I get the following response:

ld: unknown architecture of input file `myfile.txt' is incompatible with arm output

The example uses i386 but this doesn't seem to be the issue either as I can't do it that way either.

Is there a way I can force objcopy to ignore the fact it's a text file and not a valid compatible binary so it just copies it byte-for-byte into my program?

Answer 1

For data only object file (no code), you can skip binary-architecture option.

So the following should work

objcopy -I binary -O elf32-littlearm myfile.txt myfile.txt.o to generate object file.
