Failed to build gem native extension when install RedCloth-4.2.9 install Linux

Question

I want to install Octopress in my computer. I try to do it like

Octopress document.

When I run

bundle install

Answer 1

I was installing Octopress too and got the same problem as yours. After checking the mkmf.log file I figured out that gcc-4.2 had not been found. I Even installed xcode with the command line tools. It worked when I made a symlink like this:

$ sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
$ bundle install

Answer 2

Make sure you also have the build-essential package installed. You can check using

dpkg -l | grep build-essential

or simply install it without checking

sudo apt-get install build-essential

For me on Ubuntu 14.04.1 LTS, after making sure build-essential is installed, the bundle install command works/builds fine also with Ruby 1.9.3.

Answer 3

You've probably upgraded to Mountain Lion and have not rebuilt your ruby-1.9.2 install yet with the new development packages.

rvm --force install 1.9.2
gem install bundle --no-ri --no-rdoc
bundle install

If you don't have the Mountain Lion dev packages installed correctly, use the ThoughtBot instructions.

Answer 4

I fixed this issue by running

sudo apt-get install ruby-dev

as described in this blog post.

Answer 5

For Ubuntu 14.04 simply do this:

sudo apt-get install ruby1.9.3

Should work for 13.10 and 13.04 too. (Not tested)

Answer 6

My ubuntu 12.04 solution is install the ruby1.9.1-full version, that can resolve this issue.

sudo apt-get install ruby1.9.1-full

you can execute command:

sudo update-alternatives --config ruby

to select the altiernative ruby which you have installed. and then, execute below commands to finish the octopress deploy:

git clone https://github.com/erizhang/octopress.git octopress
cd octopress/
sudo gem install bundler
sudo gem install RedCloth -v '4.2.9'
bundle install
rake install

below commands you can find from octopress deploy guideline page:

rake setup_github_pages
sudo rake setup_github_pages
sudo rake generate
sudo rake deploy

Hope it's helpful for you, thanks
