What are the best compiler options for debugging in C++?
An example of an AI chatbot conversation about C++ compiler options for effective debugging.
What are the best compiler options for debugging in C++?
The best compiler options for debugging in C++ include using -g to include debug information, -O0 to disable optimizations, and -Wall to enable all warnings.
Can you explain what -g does?
The -g option tells the compiler to include debug information in the executable, which helps debuggers like GDB to provide more detailed insights.
What about optimizations? Why should I use -O0?
Using -O0 disables optimizations, making the debugging process easier because the code structure remains closer to the original source code.
Are there any other useful flags I should know about?
Yes, you might also consider -fsanitize=address for detecting memory errors and -fno-inline to prevent function inlining during debugging.
