cannot install ruby-debug gem

[azimmer]

Hi,

I seem to be in need of help from more experienced fellows like you.

I've recently changed my OS (to Win7) and thus have lost the previous
ruby environment (where I did all my Rails development work, including
debugging).

I installed ruby from rubyinstaller-1.8.7-p299.exe -- no problems.
Installed quite a few gems (including rails) -- no problem.

I, however, need to install ruby-debug as well. Whenever I try it, it
spits the following into my face:

------------------

d:\Documents\RailsProjects>gem install ruby-debug
Building native extensions. This could take a while...
ERROR: Error installing ruby-debug:
ERROR: Failed to build gem native extension.

C:/Ruby187/bin/ruby.exe extconf.rb
creating Makefile

make
Makefile:121: *** target pattern contains no `%'. Stop.


Gem files will remain installed in C:/Ruby187/lib/ruby/gems/1.8/gems/
linecache-0.43 for inspection.
Results logged to C:/Ruby187/lib/ruby/gems/1.8/gems/linecache-0.43/ext/
gem_make.out

-------------------------------

I can't get past it. Tried with outher versions of ruby-debug -- to
no avail.

Can you, please, shed some light on what's going on?

Thanks in advance,

azimmer

Seems it failed to install linecache, how that differ from the other
gem extensions?

Can you try to install a gem like hpricot or RedCloth?

This typically means that you've got a conflicting "make" in your path
(a cygwin one before your devkit one). It's worth a shot at least.

Tried and failed; see process and results below. What should I do
now? (I really am at a loss: I used to have it and worked fine,
installed with no complains. Why not now?)

Anyway. Thanks.

Thanks for the tip: I've double checked and have found that I only
have the cygwin make.

Did you installed the DevKit?
http://wiki.github.com/oneclick/rubyinstaller/development-kit

What is the output of the following commands?

SET PATH
gcc --version
make --version

*THAT* is the problem.

You should not have cygwin at all messing around.

To expect gem compiles you should have the right development tools
installed (ala: the DevKit)

mixing and matching cygwin with MinGW (the compiler used by
RubyInstaller) is bad for your health.

Yep. Cygwin make works with cygwin compiled ruby only. You'll need the devkit.

[azimmer]

Thank you, both.

I removed cygwin, installed devkit and it flies again: ruby-debug
installed as a breeze.

Thanks again.

Glad it worked.
