In modern linux almost all objects are stripped and splitted in two parts (two files). First is executable itself and second is debug symbols, stripped out from original ELF. Such files are created...

I have STM32F404 board and I am trying to flash it. I am following this tutorial. In the project Makefile $(PROJ_NAME).elf: $(SRCS) $(CC) $(CFLAGS) $^ -o $@ $(OBJCOPY) -O ihex $(PROJ_NAME).elf...

I am very very new to this, I have elf file input.out and need to create hex executable from it. I am using objcopy to create executable in intel hex format as follows objcopy -O ihex input.out ou...

I am tying to use objcopy to include a binary form of a text file into an executable. (At runtime I need the file as a string). This works fine until the linker needs to find the references from th...

Preconditions A third-party has provided a C++ executable fooapp that uses a shared object libfoo.so. The library also comes with a header foo.hpp so developers can build other applications: /* f...

So, I have this assembly file, which I assemble with GNU as and link with GNU ld using a linker script. Linker script (boot.ld): INPUT(boot.o) OUTPUT(boot.out) ENTRY(boot_start) SECTIONS { . = ...

My command-line program's build process generates a binary file (over 500KB) that currently has to be referenced by path from argv. I would like to embed this file in the executable instead. On Li...

It's a usual practice to compile with debug symbols and then separate the binary using objcopy into the release executable and the file with debug information (then wrap that into separate packages...

I have an ELF 32-bit x86 file which contains an .eh_frame section, despite my attempts1 to remove it. I'd like to remove the .eh_frame section, without touching any symbols in other sections, incl...

I would like to rename symbols inside object files (.o) with something that would be the Mac equivalent of binutils' objcopy --redefine-syms tool. I found no arm-apple-darwin10-objcopy. I tried th...

Is there a way to override functions with static scope within an object module? If I start with something like this, a module with global symbol "foo" is a function that calls local symbol "bar,"...
