Rcov installation failure on Mac OS X

Ruby
1

Hi,

I’m obviously missing something fairly obvious, but I can’t seem to
get rcov 0.3.0 to install (I had the same problem with the previous
version, but never got round to investigating), and I can’t find
anything similar in the archives or via Google. I’m running ruby
1.8.2 (2004-12-25) [powerpc-darwin8.0] under Mac OS X 10.4.6 on a G5
Mac.

This is what happens:

Thanks in advance to anyone who can point me in the right direction.

I’m not sure that the stock OS X ruby contains the headers and libraries
required to build C extensions.

I would look for ruby.h. If you don’t have it, you can’t build the
extension.

It does, but they are in “unfortunate” locations.
/usr/lib/ruby/1.8/universal-darwin8.0

is where some of the header files live.

Others and the bundles are in the right locations. You can make
symlinks or you can install ruby from source.

Just installed ruby 1.8.4 using darwinports, and now all is well.
Thanks to everyone who replied!

The rcovrt extension uses the event_hook subsystem which was added in
Ruby
1.8.3, so you can either install rcov without the extension (it will be
much
slower though), with
sudo ruby setup.rb all --without-ext
or upgrade Ruby to 1.8.4, or better yet to a stable snapshot[1],
which fixes amongst other bugs the symbol/object collision that happened
quite often on OSX.

I will update the documentation to reflect this.
