Hi,

I've been trying to brush up on my Linux FASM since moving to x86_64 with my workstation PC (Ubuntu).

I have looked into various howtos and have come up with this simple test program:
Code:
format elf executable
entry main

main:
        mov eax,1
        mov ebx,0
        int 80h    

And the Makefile to go with it:
Code:
#Makefile for helloWorld

all:
        fasm helloWorld.asm helloWorld.o
        ld -m elf_i386 -o helloWorld helloWorld.o    

However "make" ends in disaster:
Quote:
$ make
fasm helloWorld.asm helloWorld.o
flat assembler version 1.67.26 (16384 kilobytes memory)
2 passes, 96 bytes.
ld -m elf_i386 -o helloWorld helloWorld.o
ld: BFD (GNU Binutils for Ubuntu) 2.18 internal error, aborting at ../../bfd/bfd.c line 1607 in bfd_emul_get_maxpagesize

ld: Please report this bug.

make: *** [all] Error 1

Is this an actual bug, or is there some horribly wrong with my simple code?

If you are running x86_64 then I would imagine you need 64bit code in your elf exe.
Code:
format ELF64 executable    
And why are you trying to link an executable file? Did you want an object file?
Code:
format ELF64

Still, it is bug of ld, and you should report it.

Good point.

It would seem I was working on improper formats before which produced .o files, then assumed FASM always produces .o files.

Thanks. Smile
