Greetings all,

I've started to work through the pdf book available online by Paul Carter..

http://www.drpaulcarter.com/pcasm/index.php

After doing the first example i seem to be running into problems. Here is my error:

(Toggle Plain Text)

bash-2.05b$ nasm -f coff first.asm
bash-2.05b$ gcc -o first first.o driver.c asm_io.o
first.o: file not recognized: File format not recognized
collect2: ld returned 1 exit status
bash-2.05b$

At the top of the example code it says:

(Toggle Plain Text)

; file: first.asm
; First assembly program. This program asks for two integers as
; input and prints out their sum.
;
; To create the executable using djgpp:
; nasm -f coff first.asm
; gcc -o first first.o driver.c asm_io.o

%include "asm_io.inc"

So i downloaded the 'djgpp' file and placed my first.asm file in the same folder. The first command line using nasm seems to work but the second one is giving me problems, even though all the files are in the same folder.

Java is my first language so this is a little new to me. If anyone has any ideas where i am going wrong then i would really appreciate it.

Cheers

Think this is solved now, i should be using 'elf' instead of 'coff' apparently.
