#7 Non-relocatable elf object file

[Anonymous]

The problem appears if I want to use jwasm to compile mixed 16-bit and 32-bit code (e.g. boot loader). Suppose I want to write most of 32-bit code on C and compile it with gcc (elf32 objects). However, I still need to have 16-bit code and I need to compile this as elf32 object. If I compile the attached code, I get:
jwasm -4 -elf file.asm
file.asm : Error A2226: Fixup invalid for ELF: location 1

My understanding it happens because we have 32-bit relocatable offset for ELF and the code requires 16 bit offsets. Is there any way we can workaround this problem or possible create non-relocatable ELF object file? The idea is that we just need to have only 1 object with non-relocatable symbols (16-bit code) and it goes first during the linking process.

It looks like gas and gcc do not have such problem (e.g. look at any boot loader code).

Yes, there are some extensions to the ELF format implemented by LD, which make this linker understand 8- and 16-bit relocations. These were missing in JWasm, just added.
