gdb-add-index - Linux
Overview
gdb-add-index
is a command used to add index entries to the GNU Debugger (GDB) symbol table. This can be useful for quickly searching for specific functions or variables within a debugged program.
Syntax
gdb-add-index [-f] [-s <symtab>] <symfile>
Options/Flags
- -f: Force the addition of entries even if a symbol already exists.
- -s
: Specify the symbol table file to use.
Examples
Add entries from a symbol file:
gdb-add-index -f /path/to/symbols.txt
Add entries from a specific symbol table file:
gdb-add-index -s /path/to/symtab.bin /path/to/symbols.txt
Common Issues
- Duplicate entries: If a symbol already exists in the symbol table, the
-f
flag must be used to force its addition. - Invalid symbol table file: Make sure the specified symbol table file is valid and accessible.
Integration
gdb-add-index
can be used in combination with other GDB commands, such as:
- gdb: Start GDB and load a program.
- info symbols: Display the current symbol table.
- search: Search for specific symbols using the added index entries.
