cld fails to install about cld

[pokonski]

This hack worked for me on Ubuntu 16.10 with gcc 6.2.0:

CFLAGS="-Wno-narrowing" CXXFLAGS="$CFLAGS" gem install cld

@pokonski been stuck on this since eternity, but your command worked, just did CFLAGS="-Wno-narrowing" CXXFLAGS="$CFLAGS" gem install cld -i #{bundle_path} so that it installs in same directory as bundler (for people getting error doing bundle install with cld). Thanks man.

CFLAGS="-Wno-narrowing" CXXFLAGS="$CFLAGS" gem install cld

How about M1 Mac Pro? I tried a lot of times, but it still fails if I append the version.

CFLAGS="-Wno-narrowing" CXXFLAGS="$CFLAGS" gem install cld -v '0.8.0'

Just to note: I had the same problem as described above, but I was able to solve this by exporting clang as the c compiler (and its equivalents for CPP and CXX) before executing gem install cld.

can we add this hint in the README please?!

[DannyBen]

I can confirm the proposed solution also works on alpine.

Added these to my Dockerfile:

ENV CFLAGS="-Wno-narrowing"
ENV CXXFLAGS="$CFLAGS"

Would be nice if the solution is added to the README, or even nicer, if the gem is updated to not require these flags (assuming it is possible).

Fixed in 0.8.0?

cld/ext/cld/extconf.rb

Lines 4 to 5 in bd4e4a1

	ENV['CFLAGS'] = ENV['CFLAGS'].to_s + ' -Wno-narrowing'
	ENV['CXXFLAGS'] = ENV['CXXFLAGS'].to_s + ' -Wno-narrowing'

@nielsdg worked for me as well, thanks!

[grosser]

can you write up some docs for the readme ?

[DannyBen]

Fixed in 0.8.0?

I can confirm it is fixed in 0.8.0. Tested on both Alpine and Ubuntu.

I'll close this issue, feel free to comment if you think this wasn't fixed. Thanks!

@TorvaldsDB Have you reached a solution by any chance? For 0.8.0?

Nope. I skipped it. Ruby is time to be done.
