C++ Build profiles for 2024 projects

Standard development profile

This profile achieves 50% - 80% release profile performance, while also provides a reasonable amount of safety checks and debugging support. This should also be the profile for your CI build.

Compilation flags

-Og -Wall -Wextra -D_FORTIFY_SOURCE=2 -fstack-protector-strong -g -D_GLIBCXX_ASSERTIONS

Guillaume Papin(@Sarcasm) has a thorough article about compilation databases.

CMake

% mkdir build
% (cd build; cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=YES ..)
% ln -s build/compile_commands.json

Скопировать скрипт solution в директорию с модулем. Сделать его исполняемым с помощью команды:

chmod u+x solution

После этого для того, чтобы загрузить модуль solution и создать node для него с major-номером 240 нужно выполнить команду:

	#!/usr/bin/env python

	"""
	Takes as input an argument with the starting page number (from 1 to 465). Without arguments downloads all from the first page.
	"""

	import os, sys
	import urllib.request, json

	n_pages = 465

	---------------------------------------
	More important commands have a (*) by them.

	Startup
	% gdb -help print startup help, show switches
	*% gdb object normal debug
	*% gdb object core core debug (must specify core file)
	%% gdb object pid attach to running process
	% gdb use file command to load object
