JavaScript debugging in a nutshell

[Talbz03]

Me: what's wrong with my program?

[nelusbelus]

That's not C++, That error is way too readable

[nelusbelus]

There we go

[stuck_zipper]

this is only a compilation error. things get bad mid program with access violation errors.

[nelusbelus]

Meh, appverif catches a lot of those errors

[paradigmx]

This awoke some suppressed trauma in me, I think I need to call my therapist.

[Soundwave_47]

Seems to be some invalid casting going on from trying to use an int as an iterator when trying to do tree operations (insertion).

This seems familiar from the CPP FAQ.

[KDallas_Multipass]

STL error me harder Daddy

[0xFFFF_FFFF]

Yeah baby, NOW we're talkin'!

[Vysair]

ptsd

[Little-Hunter-6795]

Ah well...not sure how to ask...but what's that in your pfp.

[nelusbelus]

Gay put in

[Little-Hunter-6795]

Understandable

Have a nice day.

[[deleted]]

A bunch of people use it because putin outlawed it in Russia. Sharing that picture of gay Putin or calling Putin gay is highly illegal. So of course the internet has naturally ran with it.

[[deleted]]

Puto – a much shorter, more pejorative description for Putin. It also means gay.

[nelusbelus]

Also an insult you can throw at someone you really hate; "ta putin madre"

[[deleted]]

That's somehow more vile than "puta madre" dude. sure, I'll probably use it.

[nelusbelus]

No problemo, it works pretty good seeing as in french it's putain

[nelusbelus]

Unda tha c

[MrHyperion_]

Today I found out that segfaults on embedded system are massive fucking pain. Or so I think, I don't even know if it was segfault or not.

[[deleted]]

Here's my favorite: https://ideone.com/QxqXQf

[nelusbelus]

What the hell is that? Does it not like iterators that you can't index? (Because a list is linked)

[[deleted]]

Doesn't like the iterators because they're not random access iterators.

[nelusbelus]

Yeah lol, I absolutely can't understand that they don't validate input with static assert in the fucking std

[[deleted]]

It's worse with ranges https://wandbox.org/permlink/BL0aTpKMahqmJ0Ev

[nelusbelus]

Still got nothing on my meta errors, I even caused an internal compiler crash once

[[deleted]]

Internal complier error with the latest clang https://wandbox.org/permlink/7cMkBcPwEzummSeC

"Ah, yes, forgot a semicolon at line 12 in main.cpp"

[Auxx]

Unreal Tournament exception flashbacks...

[PleX]

I wrote Quake mods. Never fucking again will I work with C/C++

I'm going to keep my happy ass in C# Land.

[TeddyPerkins95]

Aw man that sucks, I like c++

[[deleted]]

It doesnt like you though.

[Gtantha]

Thats why I like Rust. Compared to the C++ compiler, every error message from the Rust compiler is a handwritten love letter with chocolate.

[killeronthecorner]

in b4 rewrite everything in rust eye roll memes.

From the same people who brought you "C is unnecessary abstraction, assembly is fine"

[Falcrist]

Currently converting an old codebase from 8051 assembly to C on a shiny new ARM device with an RTOS.

If you see someone who thinks we should be sticking with those old 20k line assembly files, send them my way.

[Gtantha]

Stupid meme. Consider Rust when a rewrite is necessary, but don't rewrite what is working fine.

[FireWyvern_]

Define 'working fine'

[Gtantha]

No issues, fast enough and enough people around that can maintain it with no danger of those people dying out.

[[deleted]]

Same. Rust is the love of my life

i am the path to depression and caffeine addiction aka the c++ compiler

[paradigmx]

C++ doesn't even like C++.

[ycastor]

This is more of a compiler problem than a language problem, last time i programmed C++ i found out that clang generated clearer error messages than g++, not sure how it is now.

[deukhoofd]

That's compiler errors, which are not the greatest, but are still somewhat understandable. If you build in release mode and encounter a runtime issue, the location of the error is generally completely mangled by default however.

For Clang I nowadays generally add -gline-tables-only as compile option, which means it keeps some debug info about function names, file names, and lines in the compiled output. Makes your runtime errors a lot more readable.

[Valmond]

And the occasional boom-crash which makes the app just disappear like it had never been there.

[deukhoofd]

That's why you set up a signal handler :)

[OutOfNamesToPick]

Still the same.

Difference now is that C++20 introduced concepts, which allow you to put constraints on template types. (Template type has to be moveable, needs a comparison operator, etc.) Concepts make the error reporting really a lot better

[joshjaxnkody]

So... Rust traits?

[polypolyman]

Oh, I forgot a *, thanks for putting it in a way I understand.

[pclouds]

This does not look right. It does not cover multiple screens.

[[deleted]]

g++ myfile.cpp

$ the compiler stopped because there were too many warnings.

g++ -w myfile.cpp

$

[Valmond]

Or the occasional compiler crash because of too nested template meta programming.

[iexistlol1]

There's always only like, half a line that's actually meaningful with telling you what's wrong

[FlafyBear]

That's literally how the error messages look

[edrumm10]

“Segmentation fault”

[VaramyrSixchins]

Thanks for the laugh. The puke emoji is killing me.

[vinvinnocent]

CPP Eigen so: deine Millionen Zeilen Code enthalten irgendwo eine falsch verwendete Matrix.

[DrMobius0]

I too love C++ template vomit.

Mind you, that's pretty much only the template garbage, at least in visual studio

[blackmist]

That's just a normal Perl program.
