ruby-debug Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers

Question

My Rails is 3.2.1.4, Ruby is 1.9.3p448.

I got an error when I install ruby-debug:

Building native extensions.          


        

Answer 1

The error is in the mkmf.log file. That file should be located at /home/hxh/.rvm/gems/ruby-1.9.3-p448/gems/linecache-0.46/ext/linecache/mkmf.log.

If not, you can use

sudo find / -name mkmf.log

to find it.

To troubleshoot further, see "How to install Nokogiri Ruby gem with mkmf.log saying libiconv not found?"

Answer 2

This worked for me. Nokogiri was the problem.

Try the following if you are using Alpine-Linux(or equivalent command for your OS)

apk add build-base

And then install nokogiri as given below

gem install nokogiri -- --without-pkg-config --with-libxml-2.0-config

Answer 3

For what it's worth, using Ruby 2.0.0 I was having this problem on OSX 10.10.

I ended up running brew update, which resolved some conflicts, then installed the gem and it was fine.

Answer 4

The answer of kenorb worked for me on Ubuntu 16.04 when I was trying installing rails! Thanks! I followed these steps below for installing rails:

1. sudo apt-get install ruby-full
2. sudo apt-get install libz-dev libiconv-hook1 libiconv-hook-dev
3. sudo gem install rails

Answer 5

I am using Mac El Capitan. In my case it was caused by the missing developer tool. I solved it by installing the developer tool via xcode-select --install. After that bundle install worked fine again.

Answer 6

You're most likely missing some file headers (e.g. zlib or libiconv), so try installing them.

Linux: sudo apt-get install libz-dev libiconv-hook1 libiconv-hook-dev

OS X: brew install libiconv && xcode-select --install

Otherwise check your mkmf.log file for more specific details.
