The GNU Compiler Collection contains frontends for C, C++, Objective-C, Fortran, Java, and Ada as well as libraries for these languages. It is a full-featured ANSI C compiler with support for K&R C as well. GCC provides many levels of source code error checking traditionally provided by other tools (such as lint), produces debugging information, and can perform many different optimizations to the resulting object code.

Eric is a full featured Python and Ruby editor and IDE, written in Python. It is based on the cross platform Qt GUI toolkit, integrating the highly flexible Scintilla editor control. It is designed to be usable as an everyday quick and dirty editor as well as being usable as a professional project management tool, integrating many advanced features that Python offers the professional coder. Eric includes a plug-in system, which allows easy extension of the IDE functionality with plug-ins downloadable from the net. Current stable versions are Eric4 based on Qt4 and Python 2 and Eric5 based on Python 3 and Qt4.

The GNU Debugger (GDB) is a source-level debugger for C, C++, Java, Modula-2, and several other languages. It runs on GNU/Linux, the BSD's, and almost every major proprietary OS. GDB can debug programs running on the same machine as itself, or it can communicate over a network or serial line with a debugging stub on another machine; thus, it can be used for embedded and kernel debugging.

EDB (Evan's Debugger) is a Qt4 based binary mode debugger with the goal of having usability on par with OllyDbg. It uses a plugin architecture, so adding new features can be done with ease. The current release is for Linux, but future releases will target more platforms.

Electric Fence (efence) stops your program on the exact instruction that overruns (or underruns) a malloc() memory buffer. GDB will then display the source-code line that causes the bug. It works by using the virtual-memory hardware to create a red-zone at the border of each buffer - touch that, and your program stops. Catch all of those formerly impossible-to-catch overrun bugs that have been bothering you for years.

TOra is a Toolkit for Oracle that helps the DBA or developer of a database application. It features an SQL worksheet with PL/SQL block parsing, a PL/SQL debugger and editor with syntax highlighting, a Schema browser, Unicode support, printing, and a full suite of DBA management tools.

strace is a useful diagnostic, instructional, and debugging tool. System administrators, diagnosticians, and troubleshooters will find it invaluable for solving problems with programs for which the source is not readily available.

TCP Re-engineering Tool monitors and analyzes data transmitted between a client and a server via a TCP connection. It focuses on the data stream (software layer), not on the lower level transmission protocol (as packet sniffers do).

jclasslib bytecode viewer is a tool that visualizes all aspects of compiled Java class files and the contained bytecode. In addition, it contains a library that enables developers to read, modify, and write Java class files and bytecode.

GNU DDD, the Data Display Debugger, is a GUI to command-line debuggers like GDB, DBX, JDB, XDB, Ladebug, WDB, the Perl debugger, or the Python debugger. It provides a graphical data display where complex data structures can be explored incrementally and interactively.
