Download Curl Devel Mingw32
I was doing a project in which i needed to make HTTP request to access webpages,make downloads etc. So i decided to use Curl. I downloaded and extracted it and added the libraries, bin, and includes to mingw. I am using Netbeans IDE.
So i added -lcurl in project properties->linkers->additional options but now i get the following errors. G++ -o dist/Debug/MinGW-Windows/app build/Debug/MinGW-Windows/mainConnector.o -lcurl build/Debug/MinGW-Windows/mainConnector.o: In function `Z9connectorv': C: Users 0xuser Documents NetBeansProjects app/mainConnector.cpp:8: undefined reference to `_imp__curl_global_init'..(some more similar errors). Collect2.exe: error: ld returned 1 exit status I linked the library correctly right. Then why is this showing up? Note: I Googled about this and found about linking curl library by adding -lcurl but its not working for me.

On my research i understood linking is a common problem for a newbie and even on stackoverflow.com we have similar questions(Oh yeah i readed these ). But they only answer upto adding the -lcurl. They don't say about the possibilities for that to fail as in my case.
From: jason cipriani Date: Sat, 10 Feb 2007 03:59:40 -0500 I wanted to use libcurl with mingw; but for some reason the mingw binary is missing off the download page (use the wizard, the file isn't found). Also I searched quickly and saw that a number of people had problems with libcurl 'not working' under mingw.
Here is how I got it to work on mingw using the MSVC version -- it's very simple so I thought I'd share. Do this if you want to use libcurl on mingw and you are having problems. DEVELOPMENT SETUP: 1) Visit the download wizard () and download the Win32 MSVC version of libcurl. I did not need SSL so I got the version without it.
This little guide doesn't cover SSL. 2) Visit the zlib download page () and download the current zlib *-bin package for Win32.
You'll need to do this even if you have mingw zlib already installed. If that link is broken, you can access this page by going to the libcurl download page, going all the way to the bottom and clicking on the GnuWin32 project page link, and picking zlib from the list. 3) Install libcurl by hand. They're both easy. For libcurl open up the zip file.
Copy the libcurl.dll to somewhere in your static link path (perhaps /usr/local/lib) (you do not need the.lib file). Copy the contents of the include directory to your include path (perhaps /usr/local/include). That's almost it, except. 4) To get applications to compile with curl.h using mingw gcc you have to edit one small thing in curl.h. Open up include_path/curl/curl.h. There's no such thing as a 'long long' in ISO C++. Go down to around line 94 (where all the curl_off_t typedefs are) and find the 'gcc on windows or watcom' comment: #if (defined(__GNUC__) && defined(WIN32)) defined(__WATCOMC__) /* gcc on windows or Watcom */ typedef long long curl_off_t; #define CURL_FORMAT_OFF_T '%I64d' I'm guessing, based on the format string, that it wants a 64-bit signed integer, so change that little bit of code to: #if (defined(__GNUC__) && defined(WIN32)) defined(__WATCOMC__) /* gcc on windows or Watcom */ #include typedef int64_t curl_off_t; #define CURL_FORMAT_OFF_T '%I64d' Note the stdint.h include.
Incidently, to rant, I don't really get why there's all this mess in this header anyway. Most of this stuff is already handled in system headers (like the int64_t), etc, and it seems like it would be a bit more sane to just check for the presence of those headers during autoconf and have a simple backup plan rather than doing all this system detection stuff here (and it might be nice to reduce the number of build packages from 100000 to 3 or 4). But I digress. Totalcmd Crack Serial Codes.
5) Now it's ready to go. When you compile, of course, don't forget the appropriate -I and -L paths. Link with -lcurl (gcc links with dlls just fine). RUNTIME SETUP: To actually run your application you'll have to stick the libcurl and zlib DLLs in your runtime linker path. To do this, copy libcurl.dll and zlib1.dll to either your Windows system folder, or to the same directory that your executable is in. It works great; I've been using it for a couple days now with no problems.
