I have just started to learn c by doing an old project from python. However I need to get weather data from a website and found curl. I did the first two commands for the vcpkg quick start, then followed the curl commands and running "curl -help" in cmd returns a bunch of commands. VS code autofills "curl/curl.h" but when attempting to compile with mingw64 gcc, it throws an error. The code is just includes

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

and outputs "curl/curl.h: No such file or directory"

you need to point the compiler to the path where curl.h is located

#

how do i do that?

#

-I /path/to/curl.h

#

would you know how to add that argument to vscode?

#

oh i got it

#

in case anyone else needs help with it i did

#include <C:/Users/Username/src/vcpkg/vcpkg/installed/x86-windows/include/curl/curl.h>
```but when i try to actually use it theres a bunch of "undefined reference to ..."

you need to link the libcurl library

little kelp in case anyone else needs help with it i did ```c #include <C:/Users/Username/sr...

cunning tartan `-I /path/to/curl.h`

i know this an argument but i dont know specifically where to put it for vs code to run it when compiling

You have to specify the option -I C:/Users/Username/src/vcpkg/vcpkg/installed/x86-windows/include

#

And then specify the option -L C:/Users/Username/src/vcpkg/vcpkg/installed/x86-windows/lib

#

With I think -lcurl or smt like it

like this?

"args": [
    "-fdiagnostics-color=always",
    "-g",
    "${file}",
    "-I C:\\Users\\Username\\src\\vcpkg\\vcpkg\\installed\\x86-windows\\include",
    "-L C:\\Users\\Username\\src\\vcpkg\\vcpkg\\installed\\x86-windows\\lib",
    "-lcurl",
    "-o",
    "${fileDirname}\\${fileBasenameNoExtension}.exe",
],

Remove the space after -I and -L or make those separate strings in the array

so i reinstalled where libcurl was because the "Username" after users has a space (Like "Users\User name\src") and i thought it might be messing it up. It is installed in C: now and output the following after following the above instruction:

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/12.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: skipping incompatible C:\src\vcpkg\installed\x86-windows\lib/libcurl.lib when searching for -lcurl
