#pragma comment( lib, "libcurl")

muted tree Oct 29, 2023, 10:00 AM

#

Shouldn't the linker do the same thing with the lib I added?

forest bay Oct 29, 2023, 10:41 AM

#

did you #define CURL_STATICLIB 1

orchid briar Oct 29, 2023, 12:37 PM

#

forest bay `#pragma comment( lib, "libcurl")`

not #pragma comment( lib, "libcurl.lib")?

#

is it same?

orchid briar Oct 29, 2023, 12:38 PM

#

muted tree Shouldn't the linker do the same thing with the lib I added?

it isn't automatic

muted tree Oct 29, 2023, 12:43 PM

#

orchid briar it isn't automatic

so then I would just put #pragma comment( lib, "libcurl.lib") right after the include lines?

orchid briar Oct 29, 2023, 12:44 PM

#

sure, also in the visual studio project you will need to include the lib folder in linker options

muted tree Oct 29, 2023, 12:44 PM

#

I did that already I think

orchid briar Oct 29, 2023, 12:44 PM

#

try then

muted tree Oct 29, 2023, 12:44 PM

#

the pragma says it cannot open file as well

#

is that because the file is called libcurl.a

orchid briar Oct 29, 2023, 12:45 PM

#

ok then you didn't

muted tree Oct 29, 2023, 12:45 PM

#

orchid briar Oct 29, 2023, 12:45 PM

#

oh then you have the wrong lib

#

it is for linux .a

muted tree Oct 29, 2023, 12:45 PM

#

oh x.x

#

i thought i downloaded the windows one

#

for some reason their windows one has .a extensions

orchid briar Oct 29, 2023, 12:46 PM

#

https://curl.se/windows/

muted tree Oct 29, 2023, 12:46 PM

#

orchid briar Oct 29, 2023, 12:46 PM

#

no i don't think so, i used curl also

muted tree Oct 29, 2023, 12:46 PM

#

this 64 bit one has .a

#

I can try urt download link one sec

orchid briar Oct 29, 2023, 12:46 PM

#

let me see

muted tree Oct 29, 2023, 12:46 PM

#

oh

#

same link

orchid briar Oct 29, 2023, 12:48 PM

#

wait a sec

#

maybe the fastest way is to compile libcurl with cmake in visual studio

#

in x64 release and debug

muted tree Oct 29, 2023, 12:52 PM

#

Ive never used cmake I can try rq

orchid briar Oct 29, 2023, 12:53 PM

#

download libcurl source https://github.com/curl/curl/releases/tag/curl-8_4_0 -> then open the folder on visual studio -> then wait cmake to configure itself and then compile

GitHub

Release 8.4.0 · curl/curl

✔️ changelog

#

you will get .lib compiled from visual studio

#

and also .dll and .h

#

download the zip curl

muted tree Oct 29, 2023, 12:54 PM

#

I find the hardest part of learning c++ to be building applications to start from lol

#

alr one sec lemme do all that rq

orchid briar Oct 29, 2023, 12:54 PM

#

if you learn this, you can do much more than before

muted tree Oct 29, 2023, 12:55 PM

#

btw off topic bu do you know if the clr empty project using .net framework is good for creating c++ applications, I am familiar with the c# windows form application but I wanted to create a c++ application to be faster and just to learn really?

orchid briar Oct 29, 2023, 12:57 PM

#

in c++ if you want to create gui application i suggest to work with other frameworks like QT

#

otherwise if you want to work with windows.h library and gdi+, mfc is still existent but it needs to die

muted tree Oct 29, 2023, 12:57 PM

#

I saw qt when i was reasearching what frameworks to work with wasn't sure if it was the best or not or ideal for what i wanted

orchid briar Oct 29, 2023, 12:58 PM

#

but just to learn something new

orchid briar Oct 29, 2023, 12:58 PM

#

muted tree I saw qt when i was reasearching what frameworks to work with wasn't sure if it ...

it is a good start point for doing a decent application

muted tree Oct 29, 2023, 12:58 PM

#

Ill try it out after i finish making this project lol

orchid briar Oct 29, 2023, 12:58 PM

#

it is also cross platform

muted tree Oct 29, 2023, 12:58 PM

#

oh thats good

#

can I open this curl folder inside of an existing project

#

will cmake just configure it from there?

orchid briar Oct 29, 2023, 12:59 PM

#

i created some time ago a game launcher in qt quick (private repo) with also libcurl and other libs

muted tree Oct 29, 2023, 12:59 PM

#

thats cool af fr I just wanted to create like a cool design

#

with ofc like some cool fns lol

orchid briar Oct 29, 2023, 1:00 PM

#

muted tree thats cool af fr I just wanted to create like a cool design

with qt quick you can create a cool design and write c++ code in backend (similar javascript for frontend)

#

then it should do automatically

muted tree Oct 29, 2023, 1:00 PM

#

I made this design in windows form

orchid briar Oct 29, 2023, 1:00 PM

#

open the folder from visual studio

muted tree Oct 29, 2023, 1:00 PM

#

based off some other thing i made in a lua project lol

orchid briar Oct 29, 2023, 1:00 PM

#

windows form is pretty bad

muted tree Oct 29, 2023, 1:00 PM

#

yeah its annoying to work with

orchid briar Oct 29, 2023, 1:00 PM

#

you want to do better things you will need to write custom controls

muted tree Oct 29, 2023, 1:01 PM

#

I literally just wanted to create a minimize animation to the taskbar and its so annoying to do

orchid briar Oct 29, 2023, 1:01 PM

#

with gdi+ or direct2d

#

it is a pain to do a simple custom control

muted tree Oct 29, 2023, 1:01 PM

#

yeah

#

i was going to create a custom slider

#

but it was annoying

orchid briar Oct 29, 2023, 1:01 PM

#

i had to do some graphs in mfc c++ with gdi+.... 1-2 days for just doing that

muted tree Oct 29, 2023, 1:01 PM

#

thats hell fr

orchid briar Oct 29, 2023, 1:01 PM

#

because of the bugs and unexpected behaviour of mfc

muted tree Oct 29, 2023, 1:02 PM

#

also javascript is really easy to write frontend with so I should def try qt

orchid briar Oct 29, 2023, 1:02 PM

#

try this libcurl and let me know

#

it is kinda javascript

muted tree Oct 29, 2023, 1:02 PM

#

alr can I just open the folder in an existing project will it just configure that project?

orchid briar Oct 29, 2023, 1:02 PM

#

you write the interface in qml files that you can customize with QT Creator

muted tree Oct 29, 2023, 1:02 PM

#

orchid briar Oct 29, 2023, 1:02 PM

#

then there are ways to connect c++ functions to javascript functions (backend to frontend and viceversa)

muted tree Oct 29, 2023, 1:02 PM

#

is that bad lol

orchid briar Oct 29, 2023, 1:03 PM

#

if it does finish then no

muted tree Oct 29, 2023, 1:03 PM

#

it did finish just now

#

so ig not lol

orchid briar Oct 29, 2023, 1:03 PM

#

with success?

#

print the console log

muted tree Oct 29, 2023, 1:03 PM

#

orchid briar Oct 29, 2023, 1:03 PM

#

ok it should be fine

muted tree Oct 29, 2023, 1:03 PM

#

dont mind the

#

random numbers

orchid briar Oct 29, 2023, 1:03 PM

#

now up on the visual studio bar

muted tree Oct 29, 2023, 1:03 PM

#

lmao

orchid briar Oct 29, 2023, 1:04 PM

#

compilation i think

#

then "install libcurl"

#

it should be there

#

or compile all

muted tree Oct 29, 2023, 1:04 PM

#

orchid briar Oct 29, 2023, 1:04 PM

#

Build

#

i have not visual studio in english

muted tree Oct 29, 2023, 1:04 PM

#

is it build all?

orchid briar Oct 29, 2023, 1:04 PM

#

or install

#

do a screen

muted tree Oct 29, 2023, 1:05 PM

#

orchid briar Oct 29, 2023, 1:05 PM

#

install CURL

muted tree Oct 29, 2023, 1:05 PM

#

#

got some errors

orchid briar Oct 29, 2023, 1:05 PM

#

huh that's a visual studio problem

muted tree Oct 29, 2023, 1:05 PM

#

hmm

orchid briar Oct 29, 2023, 1:06 PM

#

try build all

muted tree Oct 29, 2023, 1:06 PM

#

they both error with no supported target architecture

orchid briar Oct 29, 2023, 1:06 PM

#

ok wait a sec

#

let's return to the original pragma

#

write #pragma comment( lib, "libcurl.a")

#

and let's see if it works

#

because maybe they renamed wrongly..

muted tree Oct 29, 2023, 1:08 PM

#

#

#include <iostream>
#include <curl/curl.h>

#pragma comment( lib, "libcurl.a")

int main() {
    CURL *curl;
    CURLcode result;

    curl = curl_easy_init();

    if (curl == NULL) {
        fprintf(stderr, "HTTP request failed\n");
        return -1;
    }

    curl_easy_setopt(curl, CURLOPT_URL, "https://www.google.com");
    result = curl_easy_perform(curl);

    if (result != CURLE_OK) {
        fprintf(stderr, "Error: %s\n", curl_easy_strerror(result));
        return -1;
    }

    curl_easy_cleanup(curl);

    return 0;
}

#

this is right?

orchid briar Oct 29, 2023, 1:09 PM

#

yes it is

#

it is a curl mistake

muted tree Oct 29, 2023, 1:09 PM

#

im not sure its erroring still

#

should I switch to a previous vers

orchid briar Oct 29, 2023, 1:09 PM

#

yes but i don't think you will find the precompiled

#

let's do another thing

muted tree Oct 29, 2023, 1:10 PM
