You need to have installed MSVC 6.0 to install this (and maybe something more).

If you want to do scraping (as your message at bugtracker implies) try
scrubyt/mechanize/hpricot - they are easier to install and should do
the job (they differ in abstraction level, in fact scrubyt uses
mechanize that in turn uses hpricot)

Thank you Jano,

Can you please explain me the entire process of installing curb & why I
need to nstall MSVC6.0.

Shuvo.

I don't know the precise installation process -- I haven't installed
it and I don't want to, and I don't have time to. ;-)

However (these are more or less generic c extension requirements):

1. you need msvc 6.0 because curb contains c extension - to compile it
you need a c compiler, and that must be the same as ruby was compiled
with, therefore msvc 6. Unfortunately, it's hard to obtain it if you
don't have it already. You can also try mingw, it should be
compatible.

2. you need libcurl installed before you can compile curb (that is
what does the work in the background)
(http://my.guardpuppy.com/libcurl-7.15.1-msvc-win32-ssl-0.9.8a-zlib...)

3. then, find vsvars32.bat (in the program files/ms vs/something,
start cmd.exe, exexute vsvars32.bat and after that you are ready to
issue gem install curb.

4. I know this because the errors you posted complained about missing
tools and looking at the package.

So as I said, if you are not familiar with C development, it's better
for you to either use unix, or choose another package
(scrubit/mechanize/etc). If you are at least a bit familiar, give it a
try...

Thank You again Jano,

One thins again. I already use php curl & libcurlNET. I am familier with
C/C++ also.But never use libcurl in c/c++. So, do not know how can I
install it. I try to put libcurl.dll on the System32 dir but the result
is same.I do not want to built it again just want to use the
libcurl.dll. Can you please help me? How can I install libcurl on my
machine?

Regards,
Shuvo

I suppose you have VC6 installed.

from the zip file I mentioned, you need: 1. header files, put them in
c:/program files/msvs/vc/inc/curl
2. libcurl.dll - put it somewhere on the path
3. libcurl_imp.lib - put it into msvs/vc.lib
maybe you'll need to rename it to curl.lib to match the gem config

After that, try again *from the vsvars environment* (I suppose you
should get another kind of message when you call gem from vc
environment.

C:\Program Files\Microsoft Visual Studio\VC98\Include.I got the same

into the right path. Please help me.

These are compiler errors:

> curb_easy.h(31) : error C2236: unexpected 'struct' '$S1'
> curb_easy.h(31) : error C2027: use of undefined type '$S1'
> curb_easy.h(31) : see declaration of '$S1'

These are probably consequences of the above error.

Ok, you're doing good, you're on the right path. Now your compile
environment is right, you can compile.

The error you are facing is a problem somewhere in the sources, or in
the configuration. There's a bug filed that asks for support for
windows, so maybe it just doesn't work. I have looked at the sources,
and can't find that $S1, so I'm confused. I'll have a look tomorrow,
and maybe find something (I don't have a win box here).

In the meantime, you can try to remove the directory
(c:/ruby/lib/ruby/gems/1.8/gems/curb-0.1.2/), and try again.
