Nokogiri 1.6.4 won't compile #1188

scalp42 · 2014-11-06T00:03:28Z

Hi there,

We had to rollback to nokogiri 1.6.3.1 with libxml2 (2.9.0 instead of 2.9.2).

Log incoming.

Ubuntu 12.04 LTS

You should at least include the platform name in a report. ~~nokogiri --version is handy.~~

However, note that nokogiri does not necessarily support all versions
of libxml2.

For example, libxml2-2.9.0 and higher are currently known to be broken
and thus unsupported by nokogiri, due to compatibility problems and
XPath optimization bugs.

OK, I'll look into this. I actually meant ruby -v in the above comment.

scalp42 · 2014-11-06T00:25:13Z

That would be ruby 1.9.3p429.

knu · 2014-11-06T01:15:10Z

Thanks, now I see the problem. Because of the wrong option CFLAGS passed in are dropped. The above commit should address it.

@scalp42 Thanks, seems at least it went past the part I fixed. Now we have to look into how libxml2 is failing to build.

scalp42 · 2014-11-06T01:34:55Z

Yep indeed. We gonna pin it to the previous version of Nokogiri in the meantime but thanks a lot for looking into it @knu !

knu · 2014-11-06T01:35:42Z

@scalp42 Can you locate .../ports/libxml2/2.9.2/compile.log in the gem directory and check out what's in it?

My minion @arnaud036 got it for you @knu ! 🎉

arnaud036 · 2014-11-06T01:40:05Z

lol

knu · 2014-11-06T01:40:12Z

Thanks for the quick response! It looks like zlib is missing. Do you have zlib-dev or whatever is called in the OS? What if you installed it?

knu · 2014-11-06T01:43:05Z

Probably nokogiri can check if zlib (libz) is there before kicking the build of libxml2.

scalp42 · 2014-11-06T01:43:38Z

Worked successfully!

arnaud036 · 2014-11-06T01:44:01Z

Package that did it:

apt-get install libghc-zlib-dev

Other possible candidate:

zlib1g-dev on 12.04

scalp42 · 2014-11-06T01:44:22Z

knu · 2014-11-06T01:47:03Z

@scalp42 Great! I suppose libghc-zlib-dev might be too much; zlib1g-dev should suffice on your platform.

scalp42 · 2014-11-06T01:48:21Z

Thanks a lot for jumping on this. Do you have an idea on the timeline to push to rubygems please?

scalp42 · 2014-11-06T01:49:41Z

knu · 2014-11-06T01:54:45Z

@scalp42 Hopefully in a couple of days. Thanks much for your feedback!

knu · 2014-11-06T02:11:02Z

Added a check for zlib.

@scalp42 I'd really appreciate if you could kindly test it:

uninstall zlib1g-dev
gem install https://gems.idaemons.org/gems/nokogiri-1.6.4.1.test2.gem -- should get a failure with a message "zlib is missing; necessary for building libxml2"
reinstall zlib1g-dev
gem install https://gems.idaemons.org/gems/nokogiri-1.6.4.1.test2.gem -- should succeed just as 1.6.4.1.test1 did

FestivalBobcats · 2014-11-06T02:49:51Z

I want to kiss you all right on the mouth. Many hours spent banging head against wall... installing zlib1g-dev prior to installing the gem resolved it.

scalp42 · 2014-11-06T18:17:21Z

@knu sorry for the delay here, gonna try right now.

scalp42 · 2014-11-06T18:35:20Z

IMPORTANT NOTICE:

Buidling Nokogiri with a packaged version of libxml2-2.9.2
with the following patches applied:
    - 0001-Revert-Missing-initialization-for-the-catalog-module.patch
    - 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri --use-system-libraries
    bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

I don't see any message related to zlib missing (e7c4756)

@scalp42 Thanks for testing! I didn't expect it would find gzdopen() in -lz (which is checked with #include <zlib.h>) without zlib1g-dev installed. I wonder what package is providing zlib.h on your system.

scalp42 · 2014-11-06T23:24:29Z

@knu let me try to find which package providing it.

scalp42 · 2014-11-06T23:28:40Z

Ubuntu 12.04 reports:

http://packages.ubuntu.com/search?searchon=contents&keywords=zlib.h&mode=exactfilename&suite=precise&arch=amd64

I'll look on a box to make sure.

runs it against dpkg -s which should output the status if installed

Unfortunately, I get no matches.

The only zlib.h is the one coming from the embedded ruby in chef-client:

Which might be why nothing is being triggered ?

flavorjones · 2014-11-07T00:40:39Z

There appears to be two different issues being discussed here -- one is the
need for zlib, the other is for a bug in CFLAGS.

Would someone mind submitting a pull request to
https://github.com/sparklemotion/nokogiri.org-tutorials with updated
instructions for Ubuntu, Red Hat, etc.?

The bug for CFLAGS is fixed in nokogiri-1.6.4.1.test2.gem.

The other one for zlib is related to the actual output.

flavorjones · 2014-11-07T01:21:37Z

Riiight, I understand what you're saying, but I'd like to make sure that we
capture the (new) requirement that zlib is present for nokogiri
installation in the installation documentation.

Also, I'd like to try to capture errors in the build process during our pre-release tests. We've had build problems with a couple of recent releases and I'd like to get better about spotting these problems before release.

@knu, any ideas on what we could have done better in this instance? Do we need better platform coverage?

flavorjones · 2014-11-07T01:37:44Z

@knu, your commit breaks the windows build process. I'll poke you on Slack.

flavorjones · 2014-11-07T03:06:23Z

I've released v1.6.4.1 addressing the :werror compilation issue.

1.6.4.1 is still failing for me on Bundler:

libxml2 is missing.  Please locate mkmf.log to investigate how it is failing.

Installing with NOKOGIRI_USE_SYSTEM_LIBRARIES=1 bundle install of course worked, but it's a requirement that one would rather not have (in a team, on CI, etc.).

flavorjones · 2014-11-09T03:31:02Z

@ain can you please attach the contents of your mkmf.log? Do you have zlib dev libraries installed as mentioned above in this thread? What platform are you on (ruby and OS/distro)?

Update: upgrading Ruby to 2.1.4 resolved 1.6.4.1 installation problems.
Update: back at the issue on 2.1.5, resolved by NOKOGIRI_USE_SYSTEM_LIBRARIES=1 bundle install

Currently the 1.9.2 build is failing on Travis. Refs sparklemotion/nokogiri#1188

natevick · 2014-11-23T19:05:40Z

I'm getting the following error while building 1.6.4.1 on Mac OS X 10.9.5 Xcode 6.1 with Ruby 2.1.3, 2.1.4, 2.1.5.

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

************************************************************************
IMPORTANT NOTICE:

Buidling Nokogiri with a packaged version of libxml2-2.9.2
with the following patches applied:
    - 0001-Revert-Missing-initialization-for-the-catalog-module.patch
    - 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri --use-system-libraries
    bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

Hi @nvick, your problem is different from the one that generated this ticket. Can you please open a new issue for this? I apologize for the hassle and appreciate your help organizing the Nokogiri backlog.

See related: * GH #1188 * commits e7c4756 and 05d083c

plentz · 2016-01-20T20:22:17Z

@jonbca thanks, your solution worked (centos 7.1) :)

@arnaud036 Thanks bro

flavorjones · 2016-02-17T13:42:30Z

The original two problems described in this ticket have been fixed, one by updating compiler flags, and the other by documenting the zlib requirement in the nokogiri.org installation tutorial.

Locking ticket, please open a new one if you're experiencing problems.
