Build fail on Linux

Build fail on Linux

[grasp]

my solution is : apt-get install g++

[kanstantsin-klachkou]

gem install unf_ext -v '0.0.7.5'

and then try again bundle install

[inertia186]

Well, it says to do that right in the error. Why didn't I think of that?

I had the same issue, installing ruby-dev helped.

$ sudo apt-get install ruby-dev

[grasp]

any solution on this?

Nothing to do with this extension:

checking for main() in -lstdc++... *** extconf.rb failed *** 

This is telling you that you don't have a C++ compiler installed. You won't be able to install any native extensions that use C++.

G++ is installed

LC_ALL=C g++ --version
g++ (Gentoo Hardened 6.4.0-r1 p1.3) 6.4.0

Still the same error.

same here:

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

/Users/kjian/.rvm/rubies/ruby-2.2.4/bin/ruby -r ./siteconf20180522-62521-1v2gv2c.rb extconf.rb

checking for main() in -lstdc++... yes
creating Makefile
...
unf was resolved to 0.1.4, which depends on
unf_ext

I have installed multiple Xcode in /Applications, when compiling unf_ext, it selected the wrong Xcode.

So, when i reset the compiling toolchain to default, it worked.

sudo xcode-select -r

Now we just need to find a pendant on Linux :-)

Any fix for this?

[talezion]

Any solutions?

I get the same error.

sudo gem install unf_ext -v '0.0.7.6' --source 'https://rubygems.org/'

I was setting fastlane with Firebase Distribution and had to run bundle update

fastlane add_plugin firebase_app_distribution

Fetching unf_ext 0.0.7.6
