Linux Server debugging program tips-general Linux technology-Linux programming and kernel information, the following is a detailed description. I am definitely a cainiao. Now I want to write down my program debugging experience and learn from it later.
1. Many times, it is relatively simple to look at other people's programs, but the compiler keeps reporting errors when it is changed.
2. All virtual functions must be implemented. Otherwise, an error is returned, for example, undefined reference to vtable.
3. The intermediate files generated during the compilation process must be deleted. Otherwise, even if the source program is modified, Errors still occur when link or the execution file is generated.
4. errors are often reported for no reason. For example, "calling fdopen: Bad file descriptor" usually occurs when the gch file was last compiled and deleted (I do not know why)
