procesljao sam options i nigde nema Compiler-a.
A imas li ideju zasto iostream ne radi? To je ipak jedna od najcesce koriscenih biblioteka.
Kad kreiram projekat izaberem Empty project, da mozda ne treba nesto drugo?

Resio sam problem sa cout.
Stavio sam:
using namespace std;
Ali problem sa ostalim bibliotekama jos nisam.
Nasao sam u project properties Linker ali opet nema opcije da povezem sa nekom bibliotekom ili ja ne znam gde je.

Delimicno sam resio problem.
Nasao sam drugu verziju biblioteke koja sadrzi i curl.lib i povezao sam ga u linker-u>command line i u Tools>options>projects>VC++ directories postavio sam direktorijume include files i lib files.
ALI...
sada dobijam drugu gresku i to od moje klase:
- ------ Rebuild All started: Project: crawler2, Configuration: Debug Win32 ------
- Deleting intermediate and output files for project 'crawler2', configuration 'Debug|Win32'
- Compiling...
- glavna2.cpp
- moj_string.cpp
- crClass.cpp
- Generating Code...
- Compiling resources...
- Linking...
- glavna2.obj : error LNK2019: unresolved external symbol "public: enum CURLcode __thiscall crClass::grabPage(char *)" (?grabPage@crClass@@QAE?AW4CURLcode@@ PAD@Z) referenced in function _main
- D:\Rezanje\crawler2\crawler2\Debug\crawler2.exe : fatal error LNK1120: 1 unresolved externals
- Build log was saved at " file://d:\Rezanje\crawler2\crawler2\crawler2\Debug\BuildLog.htm"
- crawler2 - 2 error(s), 0 warning(s)
- ========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========
evo i klase koja poziva ovu grugu klasu:
- //glavna2.cpp
- #include "crClass.h"
- //#include "moj_string.h"
- #include <curl.h>
- //#include <easy.h>
- #include <iostream>
-
- using namespace std;
-
-
- int main()
- {
- CURLcode nesto;
- crClass obj;
- char *url="http://www.mycity.rs";
- nesto=obj.grabPage(url);
- cout<<nesto;
-
- return 0;
- }
Moja klasa (crClass.h):
- #include "moj_string.h"
- #include <process.h>
- #include "curl.h"
-
- class crClass
- {
- public:
- moj_string str1;
- crClass();
- CURLcode grabPage(char *url);
- ~crClass();
- };
-
- crClass.cpp:
-
- #include <iostream>
- #include "crClass.h"
-
- using namespace std;
-
- crClass::crClass()
- {
-
- }
- crClass::~crClass()
- {
- str1.~moj_string();
- }
- CURLcode grabPage(char *url)
- {
- CURL *curl;
- CURLcode page;
- curl = curl_easy_init();
- curl_easy_setopt(curl, CURLOPT_URL, url);
- page=curl_easy_perform(curl); /* ignores error */
- curl_easy_cleanup(curl);
-
- return page;
- }
Ova druga moja klasa moj_string uopste ne pravi probleme a ova koja poziva cURL pravi.
Mislim da ne prepoznaje tip CURLcode ali ukljucio sam curl.h pa me zbunjuje zasto nece.
