10 Known Causes of Trouble with GCC

This section describes known problems that affect users of GCC. Most of these are not GCC bugs per se—if they were, we would fix them. But the result for a user may be like the result of a bug.

Some of these problems are due to bugs in other software, some are missing features that are too much work to add, and some are places where people's opinions differ as to what is best.

• Actual Bugs: Bugs we will fix later.
• Cross-Compiler Problems: Common problems of cross compiling with GCC.
• Interoperation: Problems using GCC with other compilers, and with certain linkers, assemblers and debuggers.
• Incompatibilities: GCC is incompatible with traditional C.
• Fixed Headers: GCC uses corrected versions of system header files. This is necessary, but doesn't always work smoothly.
• Standard Libraries: GCC uses the system C library, which might not be compliant with the ISO C standard.
• Disappointments: Regrettable things we can't change, but not quite bugs.
• C++ Misunderstandings: Common misunderstandings with GNU C++.
• Protoize Caveats: Things to watch out for when using protoize.
• Non-bugs: Things we think are right, but some others disagree.
• Warnings and Errors: Which problems in your code get warnings, and which get errors.
