>>61547353
Because unlike Rust, you don't need to implement stupid analysers just to recompile each time in C++. The first compile takes the longest and then it's just module compile and link time optimisation. It's what makes C++ faster than rust among other reasons like a much more expressive template system.

Did you try reading up on gnu make? How about cmake? Pick one and invest like an hour and you'll never have to think about it again.

I have one make file that's general enough that I just need to add the necessarily library paths to, but I've since moved on to bazel. The only bad part about the latter is it needs java but adding dependencies literally takes a single line per file.

It's a bad pratice. Lot of bullshit would be gladly removed from the "writing code" phase if some developers actually gave attention to another areas of software engineering. Manual build of software enables fine control of what libraries are linked, when and the flags. It's useful and necessary.

Freedom is more important than retarded abstraction everywhere to enable lazy cunts like you. So, shut up and fucking read an autotools or cmake book.

>>61547719
You usually install the package from source `... make install` or through your system package manager and it grabs header files from /usr/include and links with shared objects in /usr/lib. My CMakeLists has stuff there for linking with SFML, I figured out how to set that up with a few google searches.
You usually don't bring in as many dependencies in C++ as you do in Rust / Python / JS. Usually something like a graphical library plus boost if you're feeling like bloating up your project, is enough.

Do you have a problem with GNU make syntax or are you just being a retard?
This doesn't look any more terse than the C++ code you'd be compiling with it.
Also, you don't have to use capitals for variable names, but I like to do it.

>>61547859
Your makefile also doesn't detect changes in .h files... I use to roll my own makefiles like you but I started using cmake and it saves a lot of hassle. Yes there are probably plenty of reasons why it sucks but which C++ build system doesn't?

>>61547787

Make may be a domain specific language, but it's still Turing complete and can be used to produce programs. It's just that the majority of its uses are programs that describe how to build another program.

http://nullprogram.com/blog/2016/04/30/

>>61547886
Actually, it does.
It just recompiles everything upon any change in the header files, which is fine for smaller projects, you shouldn't be touching your headers unless you made huge sweeping changes anyway.

I know you can get around this with gcc and dependency generation, but this stops being portable with compilers older than gcc 4.6 and non-GNU toolchains.

>>61547897
Is it plausible to use makefiles as a standalone truing complete language?

>>61547909

>>61547849
You have to be mentally challenged to defend this autism

>>61547921
have you never written a shell script?
The syntax is similar.

>>61547248

You don't really need a Makefile for C++ except in more complex projects. Since you mentioned in >>61547512 that you just want to build a goddamn hello world, implying that you are writing a single file program, why not simply invoke the compiler on your program?

g++ -o helloworld helloworld.cpp
./helloworld

Simple as that, no Makefile required. When you need a more complex program, you make a Makefile, just as more complex Rust programs require you to mess around with a cargo.toml file.

>>61547909

What would this look like in c++?
It just generates numbered folders in the directory you run the script.
I feel like I can just start typing and do anything with python, even with spaghetti code. But c++ is intimidating.

import os

howManyFolders = 100
prefix = 'CH'
z = []
w = 0

for i in range (0,howManyFolders + 1):
    if i < 10:
        z.append(prefix + '0' + str(i))
    elif i >= 10:
        z.append(prefix + str(i))

os.chdir(os.getcwd())

for x in z:  
    os.mkdir(z[w])
    w += 1

Not trying to shill but since I've started using D every other language feels inadequate and clunky. I'll be writing something in C++ or Java at work and all I can think about is how it could've been written faster and more concisely in D. I understand now how Lisp programmers must feel...

For scripts, python, bash, any scripting language is fine, you're just cobbling together other people's programs to do useful work without writing a new program.
You shouldn't try to write a one-off downloader script in C++ unless your needs are much more advanced than whatever the curl program can do.
Curl is literally just a shell front-end for the libcurl library which you can fully utilize in your C programs.

Nah, i'm using code by drag and drop now.

so tired of programming.

Guys, I'm 23 and my whole life I thought I wanted to be a lawyer but the only joy I've ever had doing real work involved dicking around with coding.

Experience-wise, I got nothing. Just dicking around. But I think about my future and my debt if I go two more years of school and writing memos for stuck up assholes forever and it makes me want to kill myself. Is there any hope at all for someone as old as me to drop everything and practice coding every free moment I have and possibly make a career out of it? I don't care about money anymore, I want to be happy.

        int i;
        char command[50];
        for(i = 0; i < 5; i++){

Insufferable motherfuckers

>>61548207
In C++17:

#include <filesystem>

int main(void)
{
    static const std::string prefix = "CH";
    for (int i = 0; i < 100; ++i)
    {
        std::filesystem::create_directory(prefix + std::string(i < 10 ? "0" : "") + std::to_string(i));
    }
}

>>61549011

mkdir() is a part of sys/stat.h, not unistd.h

>>61549030
redpill me on unistd.h vs stdio.h

>>61549037

unistd.h is a system header mandated on all POSIX systems. You use it for MOST Unix-related system calls, like read(), write(), open(), etc...

stdio.h is a header that is part of the C standard and required for all non-freestanding implementations. It is more portable, and includes functions like printf, fopen, fputs, fgets, etc...

If you just need console/file I/O, use stdio.h's functions
If you need access to low level Unix functions, use unistd.h.

Be aware that not all syscalls are in unistd.h. Some are in headers under the sys/ directory.

>>61548312
I'm also an ex-Dfag that's thinking of returning. I still love the language, but is there any good reason to use it over the more popular and similar C#? I like D's syntax a bit more (mostly because I used it first) but C# seems to beat it hands down in usage and support.

>>61549104
That makes a lot of sense, thank you

>not all syscalls are in unistd.h. Some are in headers under the sys/ directory
Were the syscalls divided up in logical ways? Why even split them up in the first place?

>>61549127
I'm not sure what ruby is on about. No syscalls are in unistd: they're in sys/syscall.h.

You call them with "syscall(syscall_id, ...)"

>post your unpopular programming opinions

• There is only three programming languages that I like: C, Go and Ruby.

• I think that strong static typing is a meme and it is really an illusion of safety. Why do languages like Java, C++ and C# have exceptions like ClassCastException? I never run into any typing issues.

• If you design a language for retards, only retards are going to use it. I rather have a powerful language that is like a swiss army knife, I may accidentally cut myself but it is better than a plastic spoon.

Probably.

>>61549570
This means:
1. Low level programmers can use C, which is a sane, precise and well defined language
2. C++ provides high level features at (almost) no cost to the high level programmers, which is why it became popular in the first place.
3. What you have to attain by using sanitizers, static analysis, and hundreds of hours of looking for that mutable variable you mistakenly made you can achieve them with Rust, with little or no effort.
4. Rust also has (almost) zero cost high level abstractions, and it has good PL theory behind it, which has evolved since the C++ days.

>>61549616
Exactly this. People don't use C++ because it is a "good" language. People use it because it provides a tonne high level features while providing a high performance. I never really understood the purpose of what Rust is trying to do, because it lacks the high level features that C++. Also, strong static typing is like wearing a crash helmet while driving a car.
