Gem install on Windows 7

Question

Try to install feedzirra gem

Do this:

gem install pauldix-feedzirra

I get the following error:

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing pauldix-feedzirra:

Could not create Makefile due to some reason, probably lack of

  Try passing --with-curl-dir or --with-curl-lib and --with-curl-include
  options to extconf.

Does anyone know how to fix this? Thanks

Answer 1

It seems you don't have libcurl installed:

checking for curl-config... no
checking for main() in -lcurl... no

Try this: download it and copy everything from the bin directory either to C:\\Windows\\System32 or %RUBY_ROOT%\\bin .

Answer 2

You need to download Curl (binaries and devel) . The problem you have is that it can't find the header files that usually are on devel packages.
