libcurl_a.lib(ldap.obj) Error: LNK4098, LNK2019, LNK1120

[Tomentos]

So I used setup.py to compile install the library and compiled curl manually. I linked everything in the propertys of the project but somehow I always get these errors. I already tried to change the "VC" version when I compiled curl with "nmake" but with every version I get the same error. I also added "CURL_STATICLIB" in the "Preprocessor Definitions." Everything else is working so far.

Here is the code:

#include "sleepy_discord/websocketpp_websocket.h"
#include "config.h"

class myClientClass : public SleepyDiscord::DiscordClient {
public:
    using SleepyDiscord::DiscordClient::DiscordClient;
    void onMessage(SleepyDiscord::Message message) {
        if (message.startsWith(command + "ping")) {
            sendMessage(message.channelID, "Pong!");
        }
    }
};

int main() {
    myClientClass client(token, 2);
    client.run();
}

Here is the exact error list:

I'm not sure what went wrong but maybe you need to link some windows libraries like winsock. I think it's Ws2_32.lib for sockets and crypt32.lib for cryptographic stuff.

Alright I was able to solve it. I included Ws2_32.lib and crypt32.lib already was included. But those didn't do anything.

I added Wldap32.lib in "Property pages ==> Linker ==> Input ==> Additional Dependencies" which reduced the errors to 3 Errors and 1 Warning.

Then i recompiled curl with the following command: nmake /f Makefile.vc mode=dll VC=17 ENABLE_IDN=no When you do that you need to go to "Property pages ==> Linker ==> Input ==> Additional Dependencies" again and change libcurl_a.lib to libcurl.lib I don't know how others manage their folders but if you include libcurl.lib from the original folder you need to change the name of the included folder too.

Note: I use Visual Studio 2017
