Deployment - Cannot bundle commonmarker due to cmake

[ghost]

Im using commonmarker for the HTML::Pipeline::MarkdownFilter. And when trying to deploy my app, I get this exception:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

current directory:
/home/deploy/lauroio/shared/bundle/ruby/2.4.0/gems/commonmarker-0.16.7/ext/commonmarker
/home/deploy/.rbenv/versions/2.4.1/bin/ruby -r
./siteconf20170721-22951-szfhyg.rb extconf.rb
checking for cmake... no



[ERROR]: cmake is required and not installed. Get it here: http://www.cmake.org/


*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
	--with-opt-dir
	--without-opt-dir
	--with-opt-include
	--without-opt-include=${opt-dir}/include
	--with-opt-lib
	--without-opt-lib=${opt-dir}/lib
	--with-make-prog
	--without-make-prog
	--srcdir=.
	--curdir
	--ruby=/home/deploy/.rbenv/versions/2.4.1/bin/$(RUBY_BASE_NAME)

How can I instal cmake?

It depends on your operating system! For Debian-based systems, sudo apt-get install cmake will probably do it.

Thanks @kivikakk. I had to SSHed into my server and run sudo apt-get install cmake. Its the same step, when using a local development.

Im referencing a similar issue here: #47.

We can close this issue. 👍
