I know, I just don't know how. I mean, the PDF file that says about Visual
Studio helped a lot with compiling the files, but now I seem to be having
linking problems...

I am not having any luck with the (n)make utility that starts CL compiler
from dos. I was trying with the Visual C, because I can actually read the
error msg and try to do something about it.

I think it should be libcurl.dll. I added it to the Project settings, like
the PDF file told me to. Or at least I think I did it the right way.

Jesus Christ, I am so f.ing stupid.... I went back to double check the
linker settings... and there was no libcurl.lib added there..... I am
positive I added there about two hours ago.... but there was nothing
there... I added once again and now the simple.c is executed and it does
just the same as the PDF file
(http://curl.haxx.se/libcurl/c/visual_studio.pdf) says. It does download
cnn.com or whatever...

Now, if I don't screw myself again (I am so good at doing that), I should be
able to run/build C scripts that use LIBCURL..... And hopefully I will
remember how to install the libcurl (c interface ) in the future too. I
should be puting that PDF file and these email messages on a CD... But since
I am such a lucky guy, the CD will probably break.... LOL ... so I better
memorise all of these... :-)

>You'll have to tell the linker where to look for libraries using the -L
option.

Thanks for the hint... I knew that it was something wrong with the linker,
because it said "linking errors", but I though I configured the linker
already, like that PDF file says... You should have that tutorial available
as a HTML file on your curl.haxx.se site, on the pages that talk about
installation of the C interface for Visual C. As I said, it helped me a
lot.... Thank you Rosso...

What should the LIBS path contain ? What about the INC path ?

At least now I have the C interface working (I think), if I am not gonna
mess it again. But I am still looking for a way to get the perl interface
working too... Any suggestions ? I hope that my email may be of use of some
other guys that may have problems trying to install perl/c interface onw
windows.

Thank you,
Nicusor.
