# Source Code Lookup Plugin

> Source Code Lookup attempts to look up a symbol contained within a Ghidra program, in the source of a C/C++ Eclipse project.

> This plugin requires that Eclipse, the Eclipse GhidraDev plugin, and the Eclipse CDT plugin are installed on your system.

> ## Setting up Eclipse

> > 1. Install Eclipse. The Minimum Requirements section of Extensions/Eclipse/GhidraDev/GhidraDev_README.html describes what versions of Eclipse are supported. Note that Eclipse is not provided by Ghidra...it must obtained independently.
> > 2. Install the Eclipse GhidraDev plugin into Eclipse. See Extensions/Eclipse/GhidraDev/GhidraDev_README.html for information on how to install the GhidraDev plugin into Eclipse. Your Ghidra distribution provides the most up-to-date version of the GhidraDev plugin at the time of that distribution's release.
> > 3. Install the Eclipse CDT plugin into Eclipse. The Minimum Requirements section of Extensions/Eclipse/GhidraDev/GhidraDev_README.html describes what versions of the CDT are supported. Note that the CDT is not provided by Ghidra...it must be obtained independently.
> > 4. Create a new C/C++ project (File → New → Project...) and give it a name. The other options do not matter for this plugin.
> > 5. Drag any source code for the binary into the Eclipse project
> > 6. Change the Eclipse indexer settings if necessary (Right click on your project and select Properties → C/C++ General → Indexer). Options such as "Index source files not included in the build" and "Index unused headers" will make sure that all of the files in the project get indexed if you have partial source code
> > 7. Edit the GhidraDev Eclipse preferences to point to the project you want to search (Eclipse or Window → Preferences... → GhidraDev → Symbol Lookup → Project Name). The name used here must match the name of the C++ project created in above.

> ## Using Source Code Lookup

> > To use the source code lookup feature, place the Listing cursor on the symbol you want to lookup and choose from the menu Navigation → Go To Symbol Source.

> > You can also execute this action when your cursor is in the Decompiler.

> ## Troubleshooting

> > - The port numbers may not match between Ghidra and Eclipse
> >   - Check that the Ghidra port (Ghidra Front End GUI: Edit → Tool Options... → Eclipse Integration → Symbol Lookup Port) matches the Eclipse port (Preferences → GhidraDev → Symbol Lookup → Port)
> > - The Eclipse plugin may be using the wrong project
> >   - Select the C/C++ project to be used by the Eclipse plugin (Preferences → GhidraDev → Symbol Lookup → Project Name)
