Hei!

 

Slik som jeg forstår det, er chilkat-biblioteket et typisk eksempel på hvordan et bibliotek ser ut i C++? Med include-mappe og lib-mappe?

 

Det jeg har gjort er at jeg har gått inn på:

Tools -> Options -> Projects and solutions -> VC++ Directories

 

Her har jeg under library files lagt til libs-mappa og under include files lagt til include-mappa.

 

Så tar vi en eksempel-kode som jeg finner på sida deres, for eksempel dette eksempelet:

 

#include <CkFtp2.h>
#include <CkString.h>

void ChilkatSample(void)
{
CkFtp2 ftp;

bool success;

//  Any string unlocks the component for the 1st 30-days.
success = ftp.UnlockComponent("Anything for 30-day trial");
if (success != true) {
	printf("%s\n",ftp.lastErrorText());
	return;
}

ftp.put_Hostname("ftp.chilkatsoft.com");
ftp.put_Username("****");
ftp.put_Password("****");

//  The default data transfer mode is "Active" as opposed to "Passive".

//  Connect and login to the FTP server.
success = ftp.Connect();
if (success != true) {
	printf("%s\n",ftp.lastErrorText());
	return;
}

//  Change to the remote directory where the file will be uploaded.
success = ftp.ChangeRemoteDir("junk");
if (success != true) {
	printf("%s\n",ftp.lastErrorText());
	return;
}

//  Upload a file.
CkString localFilename;
localFilename = "hamlet.xml";
CkString remoteFilename;
remoteFilename = "hamlet.xml";

success = ftp.PutFile(localFilename,remoteFilename);
if (success != true) {
	printf("%s\n",ftp.lastErrorText());
	return;
}

ftp.Disconnect();

printf("File Uploaded!\n");
}

Da får jeg disse feilene:

Hva kan dette være?

 

Er printf C kanskje? Det funker uansett ikke med .c-filendelse!

For å få bruke printf må du inkludere "stdio.h"

Er det noe mer du har glemt å inkludere? Du får mange "identifier not found" feil.

Skal prøve det med en gang jeg kommer til pcen der jeg har dette installert.

 

Men, vil denne programvaren kompilere på alle platformer, eller er det windows only?

Ja, nå gikk det. Inkluderte som følger i starten av dokumentet:

#include <stdio.h>
#include <time.h>
#include <windows.h>
#include <CkFtp2.h>
#include <CkString.h>

 

Men jeg får en linking-feil, nemlig at entry-point ikke er definert! Så jeg lager en main-funksjon og kaller denne chilkat-funksjonen jeg har laget, men da får jeg mange andre errors igjen:

Som jeg skriver i førstepost, så har jeg:

Det jeg har gjort er at jeg har gått inn på:

Tools -> Options -> Projects and solutions -> VC++ Directories

 

Her har jeg under library files lagt til libs-mappa og under include files lagt til include-mappa.

 

Hvis det trengs å gjøre noe mer enn dette, så har jeg ikke det, nei.

Høyreklikk på prosjektet ditt, velg Properties.

Under Configuration Properties - Linker - Input, legg inn de (chilkat)lib filene du trenger i Additional Dependencies. Bruk space mellom filnavnene.

Flott, da er det nemlig bare en error igjen, nemlig:

1>LINK : fatal error LNK1104: cannot open file 'C:\Users\Arne\Documents\Visual.obj'
