#GNU Compiler Collection

[bluemanedhawk]

I recently found out how to really enable all warnings in GCC: this answer on StackOverflow gives the following command. It outputs a string that can be directly fed as command-line arguments to GCC, and it also reminds me of the title text of xkcd#1638.

gcc -Q --help=warning,C \| sed -e 's/^\s\*\(\-\S\*\)\s\*\[\w\*\]/\1 /gp;d' \| tr -d '\n'

(The “,C” in the text above is not in the original answer. It can be changed if you're not using C.)

However, it's explicitly noted that this can make it impossible to do anything because some of the options are contradictory and most of them are things that are not worth caring about ever, meaning that chances are you're going to need to append some -Wno-s to the output or sprinkle your code with #pragma GCC diagnostic.

Findings so far include the following:

Append -Wno-system-headers or else the output will be flooded with problems you can't solve or even control.

You need to prepend -Wformat because of certain options that are contingent upon it, but are output before it because the options are outputted in alphabetical order.

Unless you're targeting extremely old compilers, you can append -Wno-traditional and -Wno-traditional-conversion.

Unless you're targeting C++ as well as C, you can append -Wno-c++-compat.

If you use any extensions at all, you should append -Wno-pedantic.

Twice i've used pragmas to disable -Wsuggest-attribute=format because it suggested using gnu_printf instead of printf as the third argument. I didn't turn this off at the command line because, though once is happenstance and twice is coïncidence, it is only coincidence, not thrice's enemy action or quadrice's GNOME Project official policy.

The -Wabi warning requires an argument; either respecify it and give it one or use -Wno-abi.

There's a warning called -Wunsuffixed-float-constants that warns about floating constants that don't have a suffix. This warns about all decimal double constants. There is no elegant way to suppress this because this warning is intended for codebases that use the _Decimal_X_ types.

Signal handlers can be static. It's something i'd never thought about, but makes sense now that i do.

There's a warning called -Walloca that warns on any usage of alloca, even with the appropriate header file. I tried searching DuckDuckGo for why this is and it got philosophical.

Getting Started with C Programming

1. Setting Up Your Development Environment

To start programming in C, you need to set up a development environment. Here’s how:

Choose a Compiler: Popular C compilers include GCC (GNU Compiler Collection) for Linux and MinGW for Windows. You can also use IDEs like Code::Blocks, Dev-C++, or Visual Studio.

Install the Compiler: Follow the installation instructions for your chosen compiler. Ensure that the compiler is added to your system’s PATH for easy access.

Choose a Text Editor or IDE: You can write C code in any text editor (like Notepad++ or Sublime Text) or use an Integrated Development Environment (IDE) for a more user-friendly experience.

2. Writing Your First C Program

Let’s start with a simple "Hello, World!" program to familiarize you with the syntax:#include <stdio.h> int main() { printf("Hello, World!\n"); return 0; }

Explanation:

#include <stdio.h>: This line includes the standard input-output library, allowing you to use functions like printf.

int main(): This is the main function where the program execution begins.

printf("Hello, World!\n");: This line prints "Hello, World!" to the console.

return 0;: This indicates that the program has executed successfully.

3. Understanding C Syntax and Structure

C has a specific syntax that you need to understand:

Variables and Data Types: C supports various data types, including int, float, char, and double. You must declare variables before using them.

int age = 25; float salary = 50000.50; char grade = 'A';

Operators: C provides arithmetic, relational, logical, and bitwise operators for performing operations on variables.

Control Structures: Learn about conditional statements (if, else, switch) and loops (for, while, do-while) to control the flow of your program.

4. Functions in C

Functions are essential for organizing code and promoting reusability. Here’s how to define and call a function:#include <stdio.h> void greet() { printf("Welcome to C Programming!\n"); } int main() { greet(); // Calling the function return 0; }

5. Arrays and Strings

Arrays are used to store multiple values of the same type, while strings are arrays of characters. Here’s an example:#include <stdio.h> int main() { int numbers[5] = {1, 2, 3, 4, 5}; char name[20] = "John Doe"; printf("First number: %d\n", numbers[0]); printf("Name: %s\n", name); return 0; }

6. Pointers

Pointers are a powerful feature in C that allows you to directly manipulate memory. Understanding pointers is crucial for dynamic memory allocation and data structures.#include <stdio.h> int main() { int num = 10; int *ptr = &num; // Pointer to num printf("Value of num: %d\n", *ptr); // Dereferencing the pointer return 0; }

7. Structures and Unions

Structures allow you to group different data types under a single name, while unions enable you to store different data types in the same memory location.#include <stdio.h> struct Student { char name[50]; int age; }; int main() { struct Student student1 = {"Alice", 20}; printf("Student Name: %s, Age: %d\n", student1.name, student1.age); return 0; }

What is GPL?

The GNU General Public License (GPL) is a widely used free software license that guarantees end users the freedom to run, study, share, and modify software. Originally written by Richard Stallman for the GNU Project, the GPL was designed to promote software freedom and prevent proprietary restrictions on open-source code.

The GPL is a copyleft license, meaning any derivative work must also be distributed under the same license terms. This ensures that any software derived from GPL-licensed code remains open and free for all users. In practice, if a developer modifies GPL software or incorporates GPL code into a new project, they are required to make their source code available and license it under the GPL as well.

There are multiple versions of the GPL:

GPLv1 (1989): The original version focused on preventing code from being made proprietary.

GPLv2 (1991): Introduced stricter conditions, making it incompatible with some other licenses.

GPLv3 (2007): Addressed new legal and technical issues like software patents and digital rights management (DRM), aiming for broader compatibility and stronger protections for users.

Key features of the GPL include:

Freedom to use: Anyone can use the software for any purpose.

Freedom to modify: Users can change the code to suit their needs.

Freedom to distribute: Users can share the original or modified software.

Source code availability: Distributors must provide access to the source code or offer to provide it.

The GPL has been instrumental in the growth of open-source software. Major projects like the Linux kernel and GCC (GNU Compiler Collection) use the GPL to protect their code and promote collaboration. By ensuring that software stays free and modifiable, the GPL helps build a sustainable ecosystem where innovation and transparency are prioritized over proprietary control.

Node js V12 – What are the new features in Node js V12

Node.js has been committed about their yearly updates the new features. This year their new version — V12 named Erbium is out. Here is an honest, unbiased review. Before jumping straight into the new features of Node js V12, what Node.js is let me paint what it is and what it does. Node.js is an open source framework that runs on Chrome’s V8 JavaScript engine.  It supports every OS on the market — MAC, Linux and Windows and easy on your budget.

What is Node.js?

Node.js is a platform, that supports building secure, fast and scalable network applications. Node.js is an event-driven model that doesn’t drag and is efficient for data-intensive real-time application that runs across distributed devices. Now, lets see briefly about the features in Node js V12

TLS 1.3 is now used by default Max protocol

TLS stands for Transport Layer Security, that secures communication between servers and browsers. Another notable thing about this feature is that this is the default Max protocol that offers to switch off in the CLI/NODE_OPTIONS. It is comparatively faster than TLS1.2.

Async Stack traces

Another noteworthy feature is to trace the errors of Async Stack. Previously, we won’t trace the errors in the Async await functions. Now, developers can easily do so using the asynchronous call frames of the error.stack property

Let me show you an example,

async function wait_1(x) { await wait_2(x) } async function wait_2(x) { await wait_3(x); } async function wait_3(x) { await x; throw new Error(“Oh boi”) } wait_1(1).catch(e => console.log(e.stack));

This output terminal instantly shows additional details. In this version, we can easily debug the async/wait functions.

Parser
