it'll be easier to help if you tell us what your question or issue is

quaint kestrel Jan 13, 2025, 3:24 PM

#

There is no issue, I simply lack some knowledge. I was under the impression that the tittle was self explanatory. However, I will take the liberty to redefine my thread's context. I want to send a HTTP request using the library ASIO in C++. I want to be able to send HTTP/HTTPS request with more than one method (get, post, put, delete, etc...) and with a body and headers.

asio is primarily concerned with sockets, if you don't want to invent HTTP from scratch, boost.beast uses ASIO and has HTTP client code you can use

quaint kestrel Jan 13, 2025, 3:27 PM

#

pure elbow asio is primarily concerned with sockets, if you don't want to invent HTTP from ...

Is there any way you could guide me through install boost.beast and getting it to function as intended?

pure elbow Jan 13, 2025, 3:30 PM

#

oof 😛

#

use vcpkg or something to install boost

#

or use your favorite system package manager

quaint kestrel Jan 13, 2025, 3:31 PM

#

pure elbow or use your favorite system package manager

thats the problem I have no idea how

bronze relic Jan 13, 2025, 3:37 PM

#

quaint kestrel thats the problem I have no idea how

what have you tried so far?

quaint kestrel Jan 13, 2025, 3:38 PM

#

bronze relic what have you tried so far?

Nothing, like I said I have no idea how to install a lib and get it working

bronze relic Jan 13, 2025, 3:38 PM

#

quaint kestrel Nothing, like I said I have no idea how to install a lib and get it working

have you tried googling it?

quaint kestrel Jan 13, 2025, 3:39 PM

#

bronze relic have you tried googling it?

I did, I got info about smth called choco, pacman, apt, cmake, and more

#

but I am still super confused

bronze relic Jan 13, 2025, 3:40 PM

#

you can try something like "how to install boost.beast on windows"

pure elbow Jan 13, 2025, 3:41 PM

#

what compiler/build system/IDE are you using might also make a difference

bronze relic Jan 13, 2025, 3:41 PM

#

or checking the github of the lib is already a good idea https://github.com/boostorg/beast?tab=readme-ov-file#building-tests-and-examples

#

pure elbow what compiler/build system/IDE are you using might also make a difference

im using G++ from Mingw msys2

#

on windows 10

pure elbow Jan 13, 2025, 3:44 PM

#

alright, then you have a package manager already (msys2's pacman)

#

which should be able to install the entire precompiled boost library suite

quaint kestrel Jan 13, 2025, 3:44 PM

#

I just installed the raw zip

pure elbow Jan 13, 2025, 3:44 PM

#

what

quaint kestrel Jan 13, 2025, 3:44 PM

#

pure elbow which should be able to install the entire precompiled boost library suite

how?

pure elbow Jan 13, 2025, 3:44 PM

#

that's not msys2 then thonk

quaint kestrel Jan 13, 2025, 3:45 PM

#

pure elbow that's not msys2 then <:thonk:491486269751164929>

so how do I install it with pacman and such

pure elbow Jan 13, 2025, 3:45 PM

#

following the instructions here:
https://www.msys2.org/https://www.msys2.org/
will get you a GCC compiler

#

you can then also search for boost pacman -Ss boost and install it as well

quaint kestrel Jan 13, 2025, 3:45 PM

I already have the gcc and g++ comp

pure elbow Jan 13, 2025, 3:46 PM

#

but if you don't have msys2 then you don't have a package manager

#

so that doesn't help you

quaint kestrel Jan 13, 2025, 3:46 PM

I have msys2

no idea how you installed it then but w/e

#

pick the same prefix as you did for your GCC

#

probably the ucrt64 or mingw64 one

quaint kestrel Jan 13, 2025, 3:48 PM

#

how do I install it

pure elbow Jan 13, 2025, 3:48 PM

#

pacman -S <name>

quaint kestrel Jan 13, 2025, 3:48 PM

#

like pacman install mingw-w64-ucrt-x86_64-boost?

quaint kestrel Jan 13, 2025, 3:50 PM

pure elbow ?

i think it worked

#

im not sure tho

#

and I am not sure how to include it

pure elbow Jan 13, 2025, 3:51 PM

#

take one of the examples like
https://www.boost.org/doc/libs/1_87_0/libs/beast/doc/html/beast/quick_start/http_client.html

#

#includes should just work, since it was installed to ucrt64/include where your ucrt64/bin/g++ will already look

#

you may need to link some libraries to get it to link, but headers should be found without doing anything else

pure elbow Jan 14, 2025, 3:26 PM

#

I'm at work and I don't know how to fix it

#

you'd have to read the code that is blowing up and figure out why

#

and then find out how to convince it not to

#

it looks like the code is calling _snwprintf and the standard library is being funny and doing something like

#define _snwprintf(...) _snwprintf_instead_use_StringCbPrintfW_or_StringCchPrintfW()

to let you know this function is crappy and you should use another one

#

find out where it's doing that and see if that crap is guarded by some #ifdefs

#

see if you can define something to make it not do this

quaint kestrel Jan 14, 2025, 3:31 PM

pure elbow Jan 14, 2025, 11:05 PM

#

just read about some widgets on the qt docs you need

#

buttons, text input, etc.

#

but you may need to figure out some include paths to tell the compiler yourself

#

because Qt is a rather large library that really kinda needs an actual build system to use

quaint kestrel Jan 14, 2025, 11:09 PM

#

well its not finding QApplication

pure elbow Jan 14, 2025, 11:10 PM

pure elbow Jan 14, 2025, 11:12 PM

yes, read again what I wrote

the lib requires you to make #include <QtWidgets/qtwidgetsglobal.h> work

you made #include <qt6/QtWidgets/QWidget> work

not the same thing

quaint kestrel Jan 18, 2025, 8:34 PM

do I include with i or I and do I put a space between the flag and the path or not? @pure elbow

so where is this QtGui/qtguiglobal.h

quaint kestrel Jan 18, 2025, 8:38 PM

in C:\msys64\ucrt64\include\qt6

pure elbow Jan 18, 2025, 8:38 PM

then you need to tell your compiler to look there

but I added that and now it gives me

📎 message.txt

pure elbow Jan 18, 2025, 8:39 PM

#

you resolved the compiler errors

#

now you have linker errors

#

because you need to link some qt libs I imagine

quaint kestrel Jan 18, 2025, 8:40 PM

#

damm

#

which ones?

pure elbow Jan 18, 2025, 8:40 PM

#

the one that has the definitions for the stuff you want to use

#

you're using QApplication or something

#

https://doc.qt.io/qt-6/qapplication.html

QApplication Class | Qt Widgets 6.8.1

The QApplication class manages the GUI application's control flow and main settings.

#

as you can see here, it's part of the widgets library

#

because you choose to do this all manually, now you have to find out what that library is called exactly on your system

#

maybe qt6-widgets

quaint kestrel Jan 18, 2025, 8:41 PM

#

Amazing now I have 20 pages of docs and no clue how to make a window

pure elbow Jan 18, 2025, 8:41 PM

idk

pure elbow Jan 18, 2025, 8:41 PM

#

quaint kestrel Amazing now I have 20 pages of docs and no clue how to make a window

you chose the hard way

quaint kestrel Jan 18, 2025, 8:43 PM

#

It has a lot of libs

pure elbow Jan 18, 2025, 8:43 PM

#

and you may need lots of them

#

but you will definitely need the widget one

quaint kestrel Jan 18, 2025, 8:44 PM

#

C:\msys64\ucrt64\lib\libQt6Widgets.dll.a

#

that is the widgets one

#

how does one link it

pure elbow Jan 18, 2025, 8:44 PM

#

-lQt6Widgets.dll should work I think

#

maybe the .dll is unnecessary

quaint kestrel Jan 18, 2025, 8:46 PM

#

it wants ``__imp__Z9qt_assertPKcS0_i'`

#

I tried to link Qt6Widgets but it didnt do anything

pure elbow Jan 18, 2025, 8:47 PM

#

this assert thing is probably in some other qt library shared by many of them

quaint kestrel Jan 18, 2025, 8:48 PM

#

but which one do I link?

#

do I link all of them and hope for the best?

pure elbow Jan 18, 2025, 8:49 PM

Browse the source of qtbase v6.8.1 using KDAB Codebrowser which provides IDE like features for browsing C, C++, Rust & Dart code in your browser

#

it's declared here in qtbase

#

so probably in that library

pure elbow Jan 18, 2025, 8:49 PM

#

quaint kestrel do I link all of them and hope for the best?

I guess you could 🤷

#

you could also try asking pkg-config for linker flags

quaint kestrel Jan 18, 2025, 8:50 PM

#

pure elbow it's declared here in qtbase

Qt6AxBase ?

pure elbow Jan 18, 2025, 8:50 PM

#

I don't see an Ax

quaint kestrel Jan 18, 2025, 8:52 PM

#

Well I cant find a Qt6Base.dll

#

#

these are the only QT lib files I could find with b

pure elbow Jan 18, 2025, 8:53 PM

#

you can ask pacman what files it installed for a given package,
like pacman -Ql mingw-w64-ucrt-x86_64-qt6-base

#

then check or grep for the libs

quaint kestrel Jan 18, 2025, 8:53 PM

#

what

pure elbow Jan 18, 2025, 8:54 PM

#

the package includes a Qt6Core.dll

#

that's probably it

quaint kestrel Jan 18, 2025, 8:54 PM

#

I tried to link it

#

EXACT same error

pure elbow Jan 18, 2025, 8:55 PM

#

the order matters, too

quaint kestrel Jan 18, 2025, 8:55 PM

#

AHHH

pure elbow Jan 18, 2025, 8:55 PM

#

if Qt6Widgets uses Qt6Core you need to link them in that order

quaint kestrel Jan 18, 2025, 8:56 PM

#

g++ -o terminal_emulator GUI.cpp -IC:\msys64\ucrt64\include\ -IC:\msys64\ucrt64\include\qt6 -LQt6Core -LQt6Widgets -LQt6Assert This is the command im using

pure elbow Jan 18, 2025, 8:56 PM

#

I think it should be a lowercase -l

#

uppercase is for linker search paths, IIRC

quaint kestrel Jan 18, 2025, 8:57 PM

IT COMPILED

this took me a god damm week

if you try to run it now it will probably complain about missing DLLs, unless you put that whole ucrt64/bin folder on PATH

quaint kestrel Jan 18, 2025, 8:58 PM

#

nope

#

it work

pure elbow Jan 18, 2025, 8:59 PM

#

just be aware if you want anyone else to be able to run it, they need a bunch of those .dll files

#

and technically there's additional qt plugin DLLs you might also need that need to be in specific places and other files...

#

there's a windeployqt program that can copy all that stuff for you

quaint kestrel Jan 18, 2025, 9:00 PM

#

hmm

#

I just want a window

#

but last issue

#

I am getting Errors within VSC

#

its saying random error everywhere but it works

pure elbow Jan 18, 2025, 9:01 PM

#

it might not know anything about your mingw installation

#

so it might not know where to find any headers

#

and it certainly doesn't know about the include paths you told the compiler about

quaint kestrel Jan 18, 2025, 9:08 PM

#

so if I send the EXE to someone it will not work?

pure elbow Jan 18, 2025, 9:09 PM

#

yup

#

not unless they install msys2 and install the ucrt64 qt stuff and add it to PATH

quaint kestrel Jan 18, 2025, 9:10 PM

#

whyyyy.s;s,dglomiejhadxb

pure elbow Jan 18, 2025, 9:10 PM

or you give them a nice zip with all the required stuff

quaint kestrel Jan 18, 2025, 9:11 PM

#

I regret learning C++

#

I like the backend stuff

#

but I dont waant to deal with this shit

#

Maybe in the future but I think its not for me. I will continue working on the back end stuff and completely ignore the QT stuff

#

I will work on the project just not the QT stuff I dont like it

#

lol

bronze relic Jan 18, 2025, 11:20 PM

quaint kestrel I regret learning C++

Including library in CPP has a steep learning curve, it's definitely not easy. But to be fair you seem to be trying to brute force it without actually learning or understanding what's going on so that's obviously going to make it much harder

quaint kestrel Jan 19, 2025, 2:05 PM

#

Yeah

#

I want to use CMake it make my life better

#

however I know im stupid, and I know how much extra effort its going to take to set it up and learn it and change my stuff

#

I am 13 right now. I have been doing a lot on C++ working with the stack, memory management, a bit of network stuff and more but I think I just wanna do more of that for now

@pure elbow

#

I am having another weird issue

#

I am trying to compile my project and after doing some googling I think I found the issue

#

but I cant find a solution

#

the error is 'StringCbPrintfW' was not declared in scope

pure elbow Jan 21, 2025, 11:04 AM

didn't you edit boost to make it use that? rolf

quaint kestrel Jan 21, 2025, 11:07 AM

#

These are good docs (I bookmarked them) but it seems like it has no mention of fixing This error

quaint kestrel Jan 21, 2025, 11:08 AM

#

pure elbow didn't you edit boost to make it use that? <:rolf:505104038921109525>

I fixed part of boost (one file) but there are hundreds more

pure elbow Jan 21, 2025, 11:08 AM

#

"fixed"

quaint kestrel Jan 21, 2025, 11:08 AM

#

lol

#

But yeah im not sure how to approach this one. I found a few cases of this online (Sadly not related to boost, but still helpful) and they said to include strsafe.h which im already doing and not defining some NO_USE_StringCbPrintfW

#

The error also mentions that its later defined in the translation unit

pure elbow Jan 21, 2025, 11:17 AM

start with the very first error
