You are on windows so you are most likely using nmake not make.
Secondly, you need to have a c-compiler on your system and in your path
in order for nmake to be used.
But, you should take a step back for a moment. First, this is a Ruby
issue and you are on a rails forum so you aren’t going to get much
feedback here. You should probably post something in the “ruby” forum.
Secondly, you need to list what Ruby version you are using, what windows
version you are using because that does matter. On windows, Ruby
versions are generally now compiled with mingw and if you are using
later platforms like 1.9x then you have to have the mingw compiler as
well which comes with the devkit.
Ruby is not “windows” friendly. It is far from windows friendly.
Unless you have the correct devkits, the correct compilers, it can
create many issues for you. If you are using the 1.8.6 one-click
installer then you should be ‘fairly safe’ for the most part from much
of these frustrations. However, it won’t exempt you from having issues
with gems that won’t compile correctly.
Generally I do the following in order:
gem install (gemname)
… if that fails…
gem install (gemname) --platform=mswin32
… if that fails…
gem install (gemname) --platform mswin32 --source http://gem_source_url
You should make sure that you have your gem sources updated for
gem sources -a http://gems.github.com (you only do this once)
This is the primary source now for retrieving most gems.
Other than that, compiling gems from binaries are difficult to explain
and again, it would depend on what compiler you are using, what ruby
version you are using, and what windows platform you are using.
If you are using Ruby 1.9 you can check most gems from
http://isitruby.com and validate whether or not those gems are working
for 1.9. If you are using 1.8 a lot of the gem frustrations can simply
be due to the fact that a lot of authors could care less about making
their gems usable for windows. There’s a lot of discussions about gem
building and many authors never follow the same exact standards.
Let me know if I can help you further with this issue.
