DEVELOPERS
|
|
==========
|
|
|
|
This file aims to describe an introduction for developers to work
|
|
on the code base of radare2 project.
|
|
|
|
CODE STYLE
|
|
----------
|
|
In order to contribute with patches or plugins we encourage you to
|
|
use the same coding style as the rest of the code base.
|
|
|
|
You may find some notes on this topic [here](https://github.com/radare/radare2/blob/master/CONTRIBUTING.md#coding-style-guidelines)
|
|
and doc/vim.
|
|
|
|
MODULES
|
|
-------
|
|
The radare2 code base is modularized into different libraries that are
|
|
found in libr/ directory. The binr/ directory contains the programs
|
|
that use the libraries.
|
|
|
|
It is possible to generate PIC/nonPIC builds of the libraries and also
|
|
to create a single static library, so you can use a single library
|
|
archive (.a) to link your programs and get your programs using radare
|
|
framework libraries without depending on them. See doc/static for more info.
|
|
|
|
The following presentation gives a good overview of the libraries:
|
|

|
|
|
|
API
|
|
---
|
|
As mentioned in README.md, the API itself is maintained in a different
|
|
repository. The API function definitions in C header files are derived
|
|
from and documented in the radare2-bindings repository, found at:
|
|
```sh
|
|
git clone git://github.com/radare/radare2-bindings
|
|
```
|
|
|
|
Currently the process of updating the header files from changed API
|
|
bindings requires human intervention, to ensure that proper review
|
|
occurs. Incorrect definitions in the C header files will trigger
|
|
a build failure in the bindings repository.
|
|
|
|
If you are able to write a plugin for various IDE that can associate
|
|
the bindings with the header files, such a contribution would be
|
|
very welcome.
|
|
|
|
DEPENDENCIES
|
|
------------
|
|
radare2 can be built without any special dependency. It just requires
|
|
a C compiler, a GNU make and a unix-like system.
|
|
|
|
CROSSCOMPILATION
|
|
----------------
|
|
The instructions to crosscompile r2 to Windows are in doc/windows.
|
|
|
|
You may find other documents in doc/ explaining how to build it on iOS,
|
|
linux-arm and others, but the procedure is like this:
|
|
|
|
- define `CC`
|
|
- use a different compiler profile with `--with-compiler`
|
|
- use a different OS with `--with-ostype`
|
|
- type `make`
|
|
- install in `DESTDIR`
|
|
|
|
SOURCE REPOSITORY
|
|
-----------------
|
|
The source of radare2 can be found in the following github repository.
|
|
```sh
|
|
git clone git://github.com/radare/radare2
|
|
```
|
|
Other packages radare2 depends on, such as Capstone, are pull from
|
|
their git repository as required.
|
|
|
|
To get an up to date copy of the repository you should perform the
|
|
following steps:
|
|
```sh
|
|
git pull
|
|
```
|
|
|
|
If you have conflicts in your local copy it's because you have modified
|
|
files which are conflicting with the incoming patchsets. To get a clean
|
|
source directory type the following command:
|
|
```sh
|
|
git clean -xdf
|
|
git reset --hard
|
|
```
|
|
COMPILATION
|
|
-----------
|
|
Inter-module rebuild dependencies are not handled automatically and
|
|
require human interaction to recompile the affected modules.
|
|
|
|
This is a common issue and can end up having outdated libraries trying
|
|
to use deprecated structures which may result into segfaults.
|
|
|
|
You have to make clean on the affected modules or just, if you are not
|
|
sure enough that everything is ok just make clean the whole project.
|
|
|
|
If you want to accelerate the build process after full make cleans
|
|
you should use ccache in this way:
|
|
```
|
|
export CC="ccache gcc"
|
|
```
|
|
|
|
INSTALLATION
|
|
------------
|
|
Developers use to modify the code, type make and then try.
|
|
|
|
radare2 have a specific makefile target that allows you to install
|
|
system wide but using symlinks instead of hard copies.
|
|
```sh
|
|
sudo make symstall
|
|
```
|
|
This kind of installation is really helpful if you do lot of changes
|
|
in the code for various reasons.
|
|
|
|
- only one install is required across multiple builds
|
|
- installation time is much faster
|
|
|
|
REGRESSION TESTING
|
|
------------------
|
|
|
|
The source of the radare2 regression test suite can be found in the
|
|
following github repository.
|
|
```sh
|
|
git clone git://github.com/radare/radare2-regressions
|
|
```
|
|
|
|
See the README.md file in that repository for further information.
|
|
|
|
The existing test coverage can always do with improvement, so if you can
|
|
contribute additions tests that would be gratefully accepted.
|
|
|
|
REPORTING BUGS
|
|
--------------
|
|
If you notice any misfeature, issue, error, problem or you just
|
|
don't know how to do something which is supposed to be covered
|
|
by this framework.
|
|
|
|
You should report it into the github issues page.
|
|
https://github.com/radare/radare2/issues
|
|
|
|
Otherwise, if you are looking for some more feedback I will
|
|
encourage you to send an email to any of the emails enumerated
|
|
in the AUTHORS file.
|
|
|
|
Anyway, if you want to get even more feedback and discuss this
|
|
in a public place: join the #radare channel on irc.freenode.net.
|
|
|
|
The issues page of Github contains a list of all the bugs that
|
|
have been reported classified with labels by difficulty, type,
|
|
milestone, etc. it is a good place to start if you are looking
|
|
to contribute.
|
|
|
|
CONTRIBUTING WITH PATCHES
|
|
-------------------------
|
|
All the development happens in the git repository. It is
|
|
good that all patches can be applied against the `git HEAD`.
|
|
|
|
I can get patches in unidiff format like this:
|
|
```sh
|
|
git diff > p
|
|
```
|
|
|
|
HOW TO RELEASE
|
|
--------------
|
|
|
|
- Set `RELEASE=1` in global.mk and r2-bindings/config.mk.acr.
|
|
- Use `bsdtar` from libarchive package. GNU tar is broken.
