Termux-packages: Nokogiri gem refuses to install

Created on 15 Aug 2016  路  14Comments  路  Source: termux/termux-packages

Thank you for this awesome app!!!

My objective is to install Rails in Termux but when it reach to the point of installing Nokogiri this is what I get:

Have you installed the required packages?

apt install ruby-dev libxml2-dev libxslt-dev pkg-config make clang

Could you also try with running gem cleanup first? If the problem remains, can you attach the contents of 

/data/data/com.termux/files/usr/lib/ruby/gems/2.3.0/extensions/arm-linux/2.3.0/nokogiri-1.6.8/mkmf.log

here?

Thanks, this was a regression after the recent gcc-to-clang transition, but has now been fixed int he latest clang package (version 3.8.1-2) - update to it with apt update && apt upgrade and try again!

I just did the upgrade of the clang package with apt update && apt upgrade, then I ran the gem install nokogiri -- --use-system-libraries but I still get the error:

Also, check that you have the updated clang package:

apt-cache show clang | grep Version

should output

Version: 3.8.1-2

@SpriteMidr Have you installed dependencies with:

apt install ruby-dev libxslt-dev pkg-config make clang

, run gem cleanup to ensure a clean build and then try to install nokogiri with:

gem install nokogiri -- --use-system-libraries

If so, do you get the

ERROR:  Error installing nokogiri:
    ERROR: Failed to build gem native extension.

message?

  1. [x] Installed Dependancies
  2. [x] gem cleanup
  3. [x] -- --use-system-libraries

I tried purging gem with
apt purge ruby ruby-dev -y && apt install ruby ruby-dev -y
and then tried step 3 again and it works!

Thank you very much for the help! Why do we need to
-- --use-system-libraries?

Just curious as to what caused the issue.

Thank you for helping me so quickly! It is much appreciated.

Edit: TIL GH wont support MD in email replies...

Thank you very much for the help! Why do we need to
-- --use-system-libraries?

If -use-system-libraries is not specified, nokogiri tries building bundled versions of the libraries, and this does not work due to the build process assuming that /bin/sh exists (which while generally a valid assumption, is not true on Android).

fornwall picture fornwall on 10 Jan 2017

I know it isnt to do with you guys (I dont think)... but it is a shame it doesnt also check /system/bin for sh, as (at least on my unrooted S5 w/ android 6.0.1) this has a sh executable.

Would it be difficult to develop a virtual file system with a root directory for termux to use where everything is in /bin /usr/bin, etc like on an Ubuntu or Fedora system, and then have a mount point or something that allows you to cd into the main android root file system? Or does such a thing exist?

Sorry about the questions. I am just interested in how this works. Thanks for the quick reply.

@SpriteMidr termux-chroot is available for this purpose. Install proot package to get it.
termux-chroot drops you into a proot evironment with standard mountpoints. Its really handy for development purposes.

JFYI: I could install it with:
