Hjelp til å bruke chilkat-bibliotek i VSC++

Arne · 31. august 2008

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!

JAPCU · 31. august 2008

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.

Arne · 31. august 2008

Jeg får identifier not found uansett om jeg inkluderer stdio.h og time.h.

OldMan · 31. august 2008

Prøvd å includer time.h etc før (over) chilkat headerene ?

Arne · 1. september 2008

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?

Arne · 1. september 2008

Nå prøvte jeg dette, og det funket heller ikke å inkludere time.h og stdio.h før jeg inkluderer bibliotek-filene.

OldMan · 1. september 2008

Prøv med windows.h, ser at SYSTEMTIME er definer i winbase.h.

Arne · 1. september 2008

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:

OldMan · 2. september 2008

Har du lagt til chilkat lib filene i prosjektoppsettet ditt ?

Arne · 3. september 2008

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.

OldMan · 3. september 2008

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.

Arne · 3. september 2008

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

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

OldMan · 3. september 2008

Det var rart, har du en Visual.c(pp) fil i prosjektet ditt, eller noe som gir deg en anelse om hvofor den vil ha tak i visual.obj ?

Arne · 4. september 2008

Nei, jeg har ikke noe slikt.

Har bare en fil i prosjektet, nemlig main.cpp, der koden ligger.

OldMan · 4. september 2008

Prøv google

Ser ut som om flere har problemer med Visual Studio express og dette.

MS foreslår følgende.
