# GDB Tutorial[|🔝|](#link)
- Gdb is a debugger for C (and C++). It allows you to do things like run the program up to a certain point then stop and print out the values of certain variables at that point, or step through the program one line at a time and print out the values of each variable after executing each line. It uses a command line interface.

# GCC / Clang[|🔝|](#link)
```-Wall -Wextra -Wshadow -Wnon-virtual-dtor -pedantic```
- use these and consider the following (see descriptions below)
## see descriptions below
- `-lm` - 필요하다면 표준 수학 함수를 추가한다.
- ```-pedantic``` - Warn on language extensions
- ```-Wall -Wextra``` reasonable and standard
- ```-Wshadow``` warn the user if a variable declaration shadows one from a parent context
- ```-Wnon-virtual-dtor``` warn the user if a class with virtual functions has a non-virtual destructor. This helps catch hard to track down memory errors
- ```-Wold-style-cast``` warn for c-style casts
- ```-Wcast-align``` warn for potential performance problem casts
-Wunused warn on anything being unused
- ```-Woverloaded-virtual``` warn if you overload (not override) a virtual function
- ```-Wpedantic``` (all versions of GCC, Clang >= 3.2) warn if non-standard C++ is used
- ```-Wconversion``` warn on type conversions that may lose data
- ```-Wsign-conversion``` (Clang all versions, GCC >= 4.3) warn on sign conversions
- ```-Wmisleading-indentation``` (only in GCC >= 6.0) warn if indentation implies blocks where blocks do not exist
- ```-Wduplicated-cond``` (only in GCC >= 6.0) warn if if / else chain has duplicated conditions
- ```-Wduplicated-branches``` (only in GCC >= 7.0) warn if if / else branches have duplicated code
- ```-Wlogical-op``` (only in GCC) warn about logical operations being used where bitwise were probably wanted
- ```-Wnull-dereference``` (only in GCC >= 6.0) warn if a null dereference is detected
- ```-Wuseless-cast``` (only in GCC >= 4.8) warn if you perform a cast to the same type
- ```-Wdouble-promotion``` (GCC >= 4.6, Clang >= 3.8) warn if float is implicitly promoted to double
- ```-Wformat=2``` warn on security issues around functions that format output (i.e., printf)
- ```-Wlifetime``` (only special branch of Clang currently) shows object lifetime issues
- ```-Wimplicit-fallthrough``` Warns when case statements fall-through. (Included with -Wextra in GCC, not in clang)
Consider using ```-Weverything``` and disabling the few warnings you need to on Clang
- ```-Weffc++``` warning mode can be too noisy, but if it works for your project, use it also.

```bash
libtool: finish: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/sbin" ldconfig -n /opt/gcc-15/lib/../lib64
----------------------------------------------------------------------
Libraries have been installed in:
/opt/gcc-15/lib/../lib64
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
```
