The R_X86_64_32S and R_X86_64_64 are names of relocation types, for code compiled for the amd64 architecture. You can look all of them up in the amd64 ABI. According to it, R_X86_64_64 is broken down to: R_X86_64 – all names are prefixed with this 64 – Direct 64 bit relocation and R_X86_64_32S to: R_X86_64 – prefix … Read more
Update I have grown to prefer the control John Ripley’s assembly .incbin based solution offers and now use a variant on that. I have used objcopy (GNU binutils) to link the binary data from a file foo-data.bin into the data section of the executable: objcopy -B i386 -I binary -O elf32-i386 foo-data.bin foo-data.o This gives … Read more
