The statically compiled gdb / gdbserver binaries are avaliable to download under github releases!
|
||||
|
||||
# Compiling gdb using docker
|
||||
|
||||
This repository contains a dockerfile and build scripts to compile gdb and gdbserver statically for multiple architectures.
|
||||
Currently, the supported architectures are:
|
||||
- x86_64
|
||||
- arm
|
||||
- aarch64
|
||||
- powerpc (32bit)
|
||||
You can easily expand it to support more architectures by adding the appropriate cross compilers to the dockerfile, and other build scripts.
|
||||
|
||||
NOTE: You don't need to interact with the dockerfile directly, as the Makefile will take care of everything for you.
|
||||
|
||||
## Building for a specific architecture
|
||||
|
||||
To build for a specific architecture, you can use the following command:
|
||||
```bash
|
||||
make build-<ARCH>
|
||||
```
|
||||
|
||||
For example, to build for arm:
|
||||
```bash
|
||||
make build-arm
|
||||
```
|
||||
|
||||
The resulting binaries will be placed under the `build/artifacts/` directory.
|
||||
Each architecture will have its own directory under `build/artifacts/`. For example, the arm architecture will have the following directory structure:
|
||||
```
|
||||
build/
|
||||
artifacts/
|
||||
arm/
|
||||
...
|
||||
```
|
||||
|
||||
## Building for all architectures
|
||||
|
||||
To build for all architectures, you can use the following command:
|
||||
```bash
|
||||
make build
|
||||
```
|
||||
|
||||
## Cleaning the build
|
||||
|
||||
To clean the build, you can use the following command:
|
||||
```bash
|
||||
make clean
|
||||
```
|
||||
|
||||
# Notes about this file - read before proceeding!
|
||||
|
||||
While i already provided the gdb/gdbserver-15 statically compiled binaries handed out to you, some people might want to compile it to a different architecture, or compile a newer version of gdb in the future :). This rest of the file contains my compilation documentation so that you could save yourself some time and do it yourself, if you wish.
