Chapter 13. Programming

yasm-1.3.0

Introduction to yasm

Yasm is a complete rewrite of the NASM-2.16.03 assembler. It supports the x86 and AMD64 instruction sets, accepts NASM and GAS assembler syntaxes and outputs binary, ELF32 and ELF64 object formats.

Installation of yasm

Install yasm by running the following commands: 

sed -i 's#) ytasm.*#)#' Makefile.in &&

./configure --prefix=/usr &&
make

To test the results, issue: make -j1 check.

Now, as the root user: 

make install

Command Explanations

sed -i 's#) ytasm.*#)#' Makefile.in: This sed prevents it compiling 2 programs (vsyasm and ytasm) that are only of use on Microsoft Windows.
