Debugger Setup
Configure the IDE
In order to be able to debug any of your projects, you need to make sure a the IDE is correctly configured.
These settings do not usually change. You need to make them only once after you installed Lazarus, or if you changed/updated your installation
- Open the Lazarus option dialog
The image shows where to find the option dialog in Lazarus 0.9.31 and up. In previous versions the entry is in the "Environment" menu.
- Make sure that the option "Gnu debugger (GDB)" is selected.
- The path to gdb.exe may differ:
- On Linux/Unix based systems it may be something like "/usr/bin/gdb"
- On Windows it should be in a folder called "mingw\bin\" under the directory in which Lazarus is installed.
Project Options
In order to debug your project, you need to tell the IDE to compile it in a special way, which provides additional information required by the debugger.
Please note: This will considerably increase the size of your executable (See FAQ). If you want to build a release version of your software you should switch those settings off (see also Build Modes)
The required settings are made in the "Project Options" dialog:
- You must enable the "Generate Debug Info for GDB"
- You must not use any of the following
GDB Version
GDB 7.5 is not supported by Lazarus 1.0. It can be used with trunk only.
