A Docker container configured for writing NASM x86 Assembly & C.

The container has NASM, GCC, GDB, Make, Vim, et cetera installed.

Requirements

• macOS, Linux, or Windows 10
• Docker

Setup

Make sure you've got Docker running, then run

docker compose build

Development

To load the Debian container's Bash shell run

docker compose run nasm-gcc

...and you'll see a command prompt like this

llp@fa82417446cc:/usr/src#

Compilation & Linking

The nasm-gcc/src dir is mounted from your host as a volume in the Docker container, so file changes made on the host or in the container will show up in both places. This makes it possible to edit files in your host's editor, then compile, link, and run them in the Docker container.

To compile and create an executable program from nasm-gcc/src/helloworld.asm, for example, run docker-compose run nasm-gcc to enter the container shell, then run

nasm -felf64 helloworld.asm -o helloworld.o 
ld -o helloworld.out helloworld.o           # link helloworld.out with helloworld.o
chmod u+x helloworld.out                    # give helloworld.out execute permission
./helloworld.out                            # run helloworld.out

or just make run

...and you'll see "hello world!" printed to stdout.

Disassembly

To disassemble an executable, run

ndisasm -b 64 helloworld.out > _helloworld.asm
