The following is a list of dependencies, in no particular order. This guide includes instructions for obtaining many of these at the relevant step(s). You may not need all of these, depending on which portions you are building or developing.
- Java JDK 11 (64-bit) - Free long term support (LTS) versions of JDK 11 are provided by:
- Gradle 6.4+ or 7.x
- A C/C++ compiler - We use GCC on Linux, Xcode (Clang) on macOS, and Visual Studio (2017 or later) on Windows.
- Eclipse - It must support JDK 11. Eclipse 2018-12 or later should work. Other IDEs may work, but we have not tested them.
- Git - We use the official installer on Windows. For windows you can also use the github CLI or git from with (Windows Subsystem for Linux - WSL). Most Linux distros have git in their repos. Xcode provides git on macOS. You can skip Git if you download a .zip file of the ghidra repository.
Optional unless following Manual download instructions
- Bash - This is moot on Linux and macOS. On Windows, we use MinGW. This may be distributed with Git for Windows. This can be skipped if using the automatic build.
Necessary for the development and building of Ghidra, these and more will be downloaded during the Automatic or the Manual instructions
- dex2jar. We use version 2.0.
- AXMLPrinter2
- Yet Another Java Service Wrapper. We use version 13.01 - Only to build Ghidra package.
- Eclipse PDE - Environment for developing the GhidraDev plugin.
- Eclipse CDT. We build against version 8.6.0 - Build dependency for the GhidraDev plugin.
- PyDev. We build against version 6.3.1 - Build dependency for the GhidraDev plugin.
There are many, many others automatically downloaded by Gradle from Maven Central and Bintray JCenter when building and/or setting up the development environment. If you need these offline, a reasonable course of action is to set up a development environment online, perhaps perform a build, and then scrape Gradle's cache.
If you're on Windows, install Git unless you will download a .zip clone of the ghidra repository. If you go the manual route many of the commands given below must be executed in Bash (Windows Subsystem for Linux (WSL), or Use git-bash or MSYS from MinGW).
Install OpenJDK 11 and make sure it's the default java.
Install Eclipse. You can launch Eclipse with any JRE/JDK, but you'll need to ensure Eclipse knows about your JDK 11 installation. In Eclipse, select Window -> Preferences (Eclipse -> Preferences on macOS), then navigate to Java -> Installed JREs, and ensure a JDK 11 is configured.
Install Gradle, add it to your PATH, and ensure it is launched using JDK 11.
You may choose any directory for your working copy, however these instructions will assume you have cloned the source to ~/git/ghidra.
Be sure to adjust the commands to match your chosen working directory if different than suggested:
mkdir ~/git
cd ~/git
git clone [email protected]:NationalSecurityAgency/ghidra.gitor unzip a snapshot .zip of the ghidra repository
Ghidra's build uses artifacts named as available in Maven Central and Bintray JCenter, when possible. Unfortunately, in some cases, the artifact or the particular version we desire is not available. So, in addition to mavenCentral and jcenter, you must configure a flat directory-style repository for manually-downloaded dependencies.
The flat directory-style repository can be created and populated automatically by a provided script, or manually by downloading the required dependencies. Choose one of the two following methods:
The flat directory-style repository can be setup automatically by running a simple Gradle script.
Navigate to ~/git/ghidra and run the following:
gradle -I gradle/support/fetchDependencies.gradle init
The Gradle task to be executed, in this case init, is unimportant. The point is to have Gradle execute
the fetchDependencies.gradle script. If it ran correctly you will have a new ~/git/ghidra/dependencies/
directory populated with the following files:
- flatRepo/AXMLPrinter2.jar
- flatRepo/dex-ir-2.0.jar
- flatRepo/dex-reader-2.0.jar
- flatRepo/dex-reader-api-2.0.jar
- flatRepo/dex-tools-2.0.jar
- flatRepo/dex-translator-2.0.jar
- flatRepo/dex-writer-2.0.jar
- GhidraDev/cdt-8.6.0.zip
- GhidraDev/PyDev 6.3.1.zip
- GhidraServer/yajsw-beta-13.01.zip
- fidb/*.fidb
If you see these, congrats! Skip to building or developing. If not, continue with manual download instructions below...
Create the ~/git/ghidra/dependencies/ directory and required subdirectories to hold the manually-downloaded dependencies:
mkdir ~/git/ghidra/dependencies
mkdir ~/git/ghidra/dependencies/flatRepo

cp ~/Downloads/*.fidb ~/git/ghidra/dependencies/fidb/Before building, you may want to update the version and release name.
These properties are kept in ~/git/ghidra/Ghidra/application.properties.
To build the full package, use Gradle:
gradle buildGhidraThe output will be placed in ~/git/ghidra/build/dist/.
It will be named according to the version, release name, build date, and platform.
To test it, unzip it where you like, and execute ./ghidraRun.
NOTE: Unless pre-built manually, the Eclipse GhidraDev plugin will not be included in the build. In addition, some other supporting data will also be missing. See the sections below for instructions on how to produce these components. You may also be able to copy some of these already-built components from a previous official distribution.
From the project root, execute:
gradle prepDevThe prepDev tasks primarily include generating some source, indexing our built-in help, and unpacking some dependencies.
To develop/modify Ghidra, you must first use Gradle to generate Eclipse projects. From the project root:
gradle eclipseSelect File -> Import, expand General, and select "Existing Projects into Workspace." Select the root of the source repo, and select "Search for nested projects." Select all, and Finish. You may see build path errors until the environment is properly prepared, as described below.
Some of Ghidra's components are built for the native platform. We currently support 64-bit Linux x86/ARM, macOS x86/ARM, and Windows x86.
Build the natives for your current platform using Gradle:
gradle buildNativesThis will build the decompiler, the demangler for GNU toolchains, the sleigh compiler, and (on Windows only) the PDB parser.
Optionally, to pre-compile all the language modules, you may also execute:
gradle sleighCompileIf the language modules are not pre-compiled, Ghidra will compile them at run time on an as-needed basis.
Developing the GhidraDev Eclipse plugin requires the Eclipse PDE (Plug-in Development Environment), which can be installed via the Eclipse marketplace. It is also included in the Eclipse IDE for RCP and RAP Developers. To generate the GhidraDev Eclipse projects, execute:
gradle eclipse -PeclipsePDE
Import the newly generated GhidraDev projects into Eclipse.
Note: If you are getting compilation errors related to PyDev and CDT, go into Eclipse's preferences, and under Target Platform, activate /Eclipse GhidraDevPlugin/GhidraDev.target.
See ~/git/ghidra/GhidraBuild/EclipsePlugins/GhidraDev/GhidraDevPlugin/build_README.txt
for instructions on how to build the GhidraDev plugin.
To run or debug Ghidra from Eclipse, use the provided launch configuration (usually under the "Run" or "Debug" buttons). If the launcher does not appear, it probably has not been marked as a favorite. Click the dropdown next to the "Run" button and select "Run Configurations." Then expand "Java Application" on the left to find the "Ghidra" launcher.
For running unit tests, run
gradle unitTestReport
for more complex integration tests run
gradle integrationTest
For running both unit test and integration test and generate report use
gradle combinedTestReport
For running build in headless mode on Linux, in CI environment, or in Docker, before running tests, run
Xvfb :99 -nolisten tcp &
export DISPLAY=:99
this is required to make AWT happy.
Some features of Ghidra require the curation of rather extensive databases. These include the Data Type Archives and Function ID Databases, both of which require collecting header files and libraries for the relevant SDKs and platforms. Much of this work is done by hand. The archives included in our official builds can be found in the ghidra-data repository.
This task is often done manually from the Ghidra GUI, and the archives included in our official build require a fair bit of fine tuning.
From a CodeBrowser window, select File -> Parse C Source.
From here you can create and configure parsing profiles, which lists headers and pre-processor options.
Then, click Parse to File to create the Data Type Archive.
The result can be added to an installation or source tree by copying it to ~/git/ghidra/Ghidra/Features/Base/data/typeinfo.
This task is often done manually from the Ghidra GUI, and the archives included in our official build require a fair bit of fine tuning. You will first need to import the relevant libraries from which you'd like to produce a FID database. This is often a set of libraries from an SDK. We include a variety of Visual Studio platforms in the official build. The official .fidb files can be found in the ghidra-data repository here https://github.com/NationalSecurityAgency/ghidra-data/tree/master/FunctionID
From a CodeBrowser window, select File -> Configure. Enable the "Function ID" plugins, and close the dialog. Now, from the CodeBrowser window, select Tools -> Function ID -> Create new empty FidDb. Choose a destination file. Now, select Tools -> Function ID -> Populate FidDb from programs. Fill out the options appropriately and click OK.
If you'd like some details of our fine tuning, take a look at ~/git/ghidra/Ghidra/Features/FunctionID/data/building_fid.txt.
The Debugger consists of multiple modules comprising its own collection of utilities, frameworks, and features. There is plenty of new ground to be broken. Before getting too deep into it, please see our dedicated Debugger Developer's Guide.
