nasm

The Netwide Assembler, a portable 80x86 assembler.

Assemble source.asm into a binary file source, in the (default) raw binary format:

nasm {{source.asm}}

Assemble source.asm into a binary file output_file, in the specified format:

nasm -f {{format}} {{source.asm}} -o {{output_file}}

List valid output formats (along with basic nasm help):

nasm -hf

Assemble and generate an assembly listing file:

nasm -l {{list_file}} {{source.asm}}

Add a directory (must be written with trailing slash) to the include file search path before assembling:

nasm -i {{/path/to/include_dir/}} {{source.asm}}
