Configuration

docker-compose.yml

  • BUILD_MULTI: set true to enable NoPwnDocker compiling multiarch GDB (WILL OCCUPY 2G~ DISK)

There's not much can be modified. But you do can change something.

  • open Dockerfile, you can change the version and proxy.
  • open docker-compose.yml, you can change the container name.
  • modify starship.toml to use your own starship style.
  • modify .gdbinit to use your own gdbinit config.

Usage or features

gdb

init-gef、init-pwndbg to load different gdb plugin.

zsh

zsh-autosuggestions plugins

build_glibc

A shell file to build glibc source with debug in one command. bash ~/build_glibc.sh -h

There could be some bug when building older version of glibc. Check below to see the solution. (at least for me)

`loc1@GLIBC_2.2.5' can't be versioned to common symbol 'loc1'

♻️ Refactor Dockerfile and docker-compose.yml

2023/03/23

🔥 Remove build_glibc32.sh and build_glibc64.sh, add build_glibc.sh for general usage. :fire: Remove built-in glibc to reduce the docker size and build time.
