@section debugSymbols Enabling debug symbols
The --enable-debug flag can be useful when developing, since it
makes the compiler produce more abundant debugging information that
can be read by a debugger.
There are flags that make the compiler produce more abundant debugging
information that can be read by a debugger. When `--buildtype=debug` is added
to `meson setup`, it passes one of these flags to the compiler: `-g`.
Some compilers don't document some of the flags, such as clang for
-g3. However, practice shows that clang behaves the same way as g++
@@ -20,7 +20,12 @@ in that regard. As an experiment, providing -g4 results in
`error: unknown argument: '-g4'`, but providing -g3 succesfully
compiles, and supposedly puts it into effect.
On top of that, the flag enables log4cplus's own logging, and adds
more sanity checks in DNS code.
Disabling optimizations via `-O0` is also recommended for debugging.
g++ also provides `-ggdb`.
The `-D tests=enabled` flag besides enabling unit tests, also enables useful
debugging functionality: log4cplus's own logging, and adds more sanity checks
in DNS code.
