Error while installing ruby-1.8.7 on Fedora 15 - ruby

Question

Using RVM, I tried to install ree-1.8.7-2011.03 after installing Fedora 15 and I get the following error. Using rvm install ree-1.8.7-2011.03 on Ubuntu 11.04 works fine..
Same error (and solution) with MRI ruby-1.8.7-p334 on Fedora 15.
Any ideas as to how to fix this?

Answer 1

This also happens when installing ruby-1.8.7 with rvm in Fedora 15.
Reinier Balt's answer also works, in my case I had to install system wide ruby using yum.
Here's what I did:
cd ~/.rvm/src/ruby-1.8.7-p334/ext/dl
ruby mkcallback.rb > callback.func
ruby mkcbtable.rb > cbtable.func

Answer 2

I saw this too
I went into the src/ext/dl directory and manually generated callback.func and cbtable.func which are both incomplete. I had to do
rm callback.func
touch callback.func
ruby mkcallback.rb >> callback.func
(repeat for cbtable)
Somehow the simple ruby mkcallback.rb > callback.func did not work
then rerun rvm install 1.8.7 which will not overwrite your changes.

[[tl;dr: see patch at bottom]]

Answer 4

I don't know why this happens, but it appears that the redirection to the file doesn't completely redirect the output. As a temporary hack/fix, that does get it working, you can pipe it through tee. It gets the job done, but is certainly not the proper solution.
Patch:
https://gist.github.com/1083163
This patch when applied like so: rvm install --patch /path/to/Fedora-15-ruby-1.8.7-p352.patch%0 ruby-1.8.7 will work. I will test it with ree as well and update.
EDIT: This same patch also works with ree.
rvm install --patch /path/to/Fedora-15-ruby-1.8.76-p352.patch%0 ree successfully installed a working ree for me.

patch from user865548 is now available in RVM (will be 1.9.1 or just rvm get head)
