ruby-debug won't install / build native extensions

Question

I have searched high and low for a solution. I have both linecache19 and ruby_core_source installed.

Neither of these commands will work:

gem install ruby-debug19
gem install ruby-debug19 -- --with-ruby-include=/Users/benjohnson/.rvm/src/ruby-1.9.1-p378

Here is the error I keep getting:

Building native extensions.  This could take a while...

Does ` /Users/benjohnson/.rvm/gems/ruby-1.9.1-p378/gems/ruby-debug-base19-0.11.24/ext/ruby_debug/gem_make.out` contain any additional information that wasn't already output to stdout? – Seftton

Nope, the same exact error messages as above. Nothing additional. – Glycerin

I have the exact same problem. Would be glad for any help! – Concuss

Answer 1

I have had the same issue (on 1.9.1 and 1.9.2). Even trying to install 0.11.23 triggered the error. I found that it was necessary to:

• Uninstall the gem (all versions for me):

  gem uninstall ruby-debug-base19

• Delete the 0.11.24 directory (in my case: ~/.rvm/gems/ruby-1.9.2-p0/gems/ruby-debug-base19-0.11.24/)

• install 0.11.23 explicitly:

  gem install ruby-debug-base19 --version=0.11.23

This is where I got most of the solution: http://rails.brentsowers.com/2010_08_01_archive.html

Additionally, if you use Bundler:

I had problems until I upgraded to latest Bundler (1.0.2 => 1.0.7) as it insisted on installing ruby-debug-base19 v 0.11.24).

In your Gemfile, make sure you've pinned the version of ruby-debug-base19:

gem "ruby-debug-base19", "0.11.23", :require => nil

Answer 2

This one works best for me, because it don't seems too hackish:

gem install ruby-debug19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-head/

don't forget to set $rvm_path. In my case, the last folder was ruby-1.9.3-head - pick the right one for you.

got this answer from here: ruby-debug install error: failed to build gem native extension

+1 this one worked... just make sure to use the correct ruby directory.. in my case was $rvm_path/src/ruby-1.9.3-p448/ – Graiae

Answer 3

on Debian/Ubuntu/Mint this issue could be solved by installing some of these packages (I'm not sure which is causing the problem)

apt-get install libcurl4-openssl-dev libgcrypt11-dev libgnutls-dev libidn11-dev libldap2-dev librtmp-dev libtasn1-3-dev m4

Triangular

This limited set also worked for me: apt-get install libcurl4-openssl-dev libgcrypt11-dev libgnutls-dev libidn11-dev libldap2-dev librtmp-dev libtasn1-3-dev m4 – Hajj

Answer 4

Do you have gcc installed and path to gcc.exe referenced in your PATH environment variable? This solved similar problem for me, probably this could your solution too!

Answer 5

For the version of ruby I was working with I had to add both of these lines to my Gemfile

gem 'ruby-debug-base19', '0.11.23'

gem "ruby-debug19"
