gdb 🪲

GDB is a tool used for debugging

to use, compile code using the -g flag

e.g. gcc -Wall -Werror -g -o file file.c

(this adds metadata to the executable file that allows gdb to )

run GDB with gdb ./file

<aside> ❓ is lldb a suitable alternative for mac? https://lldb.llvm.org/use/map.html

• running gdb will open up a ‘sub-terminal’ that allows us to run commands

main usage of gdb is to debug segmentation faults (since they are hard to debug)

valgrind 🛁

valgrind is a program that tries to detect memory leaks (memory that isn’t freed by the program)

similarly to gdb, compile with -g flag and run with valgrind ./file
