Hi... I'm new to the forum, and hope very much someone can help....

I am attempting to install libcurl on windows, using Visual Studio
2008 professional.

I have downloaded multiple instances of libcurl. The second version
was more promising,
but I get stuck on connot open curllib.dll.

Here are my steps and results:

*********************************************************************************************
I tried curl-7-21.4.

I clicked on the solution vc6curl.sln and click on build for libcurl.
It goes through and builds all the of the .c files... The result output says:

I get 1 warning:

transfer.c
.\transfer.c(553) : warning C4244: 'function' : conversion from
'time_t' to 'long', possible loss of data

Then the final output:

Generating Code...

    Creating library DLL-Debug/libcurld_imp.lib and object

Build log was saved at
"file://c:\CPS271\CPS271_Library\curl-7.21.4\lib\DLL-Debug\BuildLog.htm"
libcurl - 0 error(s), 1 warning(s)
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

I then go to: curl-7.21.4/lib/DLL-Debug and do not find any
references to libcurl.dll.
I only find libcurl.res.

*********************************************************************************************

I then downloaded: libcurl-7.19.3-win32-ssl-msvc.zip which unzipped
provided the curllib.dll

Then under Studio I go project properties, linker, input and put in curllib.dll
under c/c++/general I add the include and lib paths

Under tools/options/vc++directories, i add the include and lib paths

When I go to build the solution, I get an error:
fatal error LNK1104: cannot open file 'curllib.dll'

Here is the demo program:
/*
  * This is a very simple example of how to use libcurl from within
  * a C++ program. The basic idea is that you want to retrieve the
  * contents of a web page as a string. Obviously, you can replace
  * the buffer object with anything you want and adjust elsewhere
  * accordingly.
  *
  * Hope you find it useful..
