Beyond Linux® From Scratch (System V Edition) - Version r12.4-426

Chapter 13. Programming

yasm-1.3.0

Introduction to yasm

Yasm is a complete rewrite of the NASM-3.01 assembler. It supports the x86 and AMD64 instruction sets, accepts NASM and GAS assembler syntaxes and outputs binary, ELF32 and ELF64 object formats.

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Installation of yasm

First, fix a problem when building with gcc-15: 

sed -e 's/def __cplusplus/ defined(__cplusplus) || __STDC_VERSION__ >= 202311L/' \
    -i libyasm/bitvect.h

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.

Short Descriptions

yasm

is a portable, retargetable assembler that supports the x86 and AMD64 instruction sets, accepts NASM and GAS assembler syntaxes and outputs binaries in ELF32 and ELF64 object formats

libyasm.a

provides all of the core functionality of yasm, for manipulating machine instructions and object file constructs
