Frequently asked questions

How do you pronounce Ghidra?

Gee-druh. The G sounds like the G in goto, great, good, graph, and GitHub. The emphasis goes on the first syllable.

When I run Ghidra, all I see is "Java runtime not found..." How do I get Ghidra to run?

Download and install OpenJDK 11 and add its bin directory to your system's PATH. For detailed instructions on adding Java to your PATH, see the Ghidra Installation Guide.

My system requires Java 8 (or another Java) to be on the PATH for other software to function correctly. How can I get Ghidra to run without altering the PATH?

Ghidra uses an existing Java runtime on the PATH (Java 1.7 or later) to locate a version of Java that Ghidra supports (in this case, Java 11). If Ghidra fails to find Java 11 in the standard locations, you will be prompted to enter the path to Java 11's installation directory. Note that this path should be Java's installation directory (also called "java home"), not the bin directory found within the installation directory.

Where is the complete Ghidra source code?

This repository is a placeholder for the full open source release. Be assured efforts are under way to make the software available here. In the meantime, enjoy using Ghidra on your SRE efforts, developing your own scripts and plugins, and perusing the over a million lines of Java and Sleigh code released within the initial public release. The release can be downloaded from our project homepage at www.ghidra-sre.org. Please consider taking a look at our contributor guide to see how you can participate in this open source project when it becomes available.

Does Ghidra have a dark theme?

Ghidra provides the ability to invert the colors of its GUI, providing a "darkish" "theme." Icons and help documents are not affected by the color inversion. To invert the colors from the Front End GUI, do Edit → Tool Options... → Tool, enable "Use Inverted Colors," and restart Ghidra.
