The GNU* Project Debugger (GDB) provided with the Intel® Parallel Studio XE Composer Edition is based on GDB with enhancements provided by Intel.

It can debug applications on IA-32 or Intel® 64 Architecture systems.

Attention: In the coming releases of GDB, the included Python* runtime will contain the highest version of Python 3. The present release includes the Python 2.7 version.

IA-32/Intel® 64 Architecture debugging

Debug applications natively on IA-32 or Intel® 64 Architecture systems.


Always source the following script in the same environment where you use the debugger:

source <install-dir>/bin/

<install-dir> is the installation directory, by default, it is:

  • For root users: /opt/intel/<suitename>
  • For non-root users: $HOME/intel/<suitename>

For other prerequisites, new debugger features, hardware and software requirements, and known issues refer to the release notes.

Start GDB for Native IA-32/Intel® 64

To debug applications natively on IA-32 or Intel® 64 Architecture systems, start GDB with the following command:


The actual debugger usage is the same as for the GNU* Project Debugger. Extensions for IA-32/Intel® 64 Architecture are described in the debugger documentation.
