Can't link cURL with MinGW

[Nielyboyken]

Hi

I'm trying to compile cURL with MinGW (G++-), but it ain't working.

This is the G++ command I'm using: g++ c:/users/5tif/desktop/example04.cpp -o c:/users/5tif/desktop/example04 -lcurl

At first I got the error:

c:/mingw/bin/../lib/gcc/mingw32/4.9.3/../../../../mingw32/bin/ld.exe: cannot find -lcurl
collect2.exe: error: ld returned 1 exit status

Then I copied the two files from this folder:
[font="Courier New"]C:\Users\5TIF\Downloads\curl-7.48.0-win64-mingw\curl-7.48.0-win64-mingw\lib[/font]
(libcurl.a and libcurldll.a) to my MinGW/lib folder.

When I tried the same G++ command again I got this second 'error':

This is the example code I'm trying to compile:

This is the tree of my MinGW folder (libs and include):

I'm using Windows 10 64-bit, what am I doing wrong?
Compiling simple libraries like SFML is lucking for me, but I never seem to be able to compile big libraries like libcurl.
Yet, it's very important to know how to do it.

What am I doing wrong?
Thanks!
What am I doing wrong and how to fix it?

It is necessary to specify the library folder location where libcurl is located. This is done in g++ with the -L option.

For example, on my machine I install dev stuff to C:\Dev:
g++ -LC:\Dev\curl\lib example04.cpp -lcurl -o example04.exe

[Nielyboyken]

Did that still getting same error. And MinGW automatically links to it's default lib folder anyway.

Shouldn't you be linking to curlpp?
