Nokogiri 1.6.4 won't compile #1188

Closed scalp42 closed 9 years ago

scalp42 commented 10 years ago

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

knu commented 10 years ago

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

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

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.

That would be ruby 1.9.3p429.

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 commented 10 years ago

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 commented 10 years ago

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

scalp42 commented 10 years ago

My minion @arnaud036 got it for you @knu ! :tada:

arnaud036 commented 10 years ago

lol

knu commented 10 years ago

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 commented 10 years ago

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

scalp42 commented 10 years ago

Worked successfully!

arnaud036 commented 10 years ago

Package that did it:

apt-get install libghc-zlib-dev

Other possible candidate:

zlib1g-dev on 12.04

scalp42 commented 10 years ago

knu commented 10 years ago

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

scalp42 commented 10 years ago

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

scalp42 commented 10 years ago

knu commented 10 years ago

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

knu commented 10 years ago

Added a check for zlib.

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

  1. uninstall zlib1g-dev
  2. 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"
  3. reinstall zlib1g-dev
  4. 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 commented 10 years ago

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.

jonbca commented 10 years ago

And if you're a CentOS/RHEL user, it's sudo yum install zlib-devel

scalp42 commented 10 years ago

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

scalp42 commented 10 years ago

************************************************************************
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 (https://github.com/sparklemotion/nokogiri/commit/e7c47565323ddcc08355fa1aa62432a9881ca706)

knu commented 10 years ago

@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 commented 10 years ago

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

scalp42 commented 10 years ago

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.

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

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.?

  • use apt-file to seach for that zlib library
  • grab every package matching
  • runs it against dpkg -s which should output the status if installed

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 commented 10 years ago

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 commented 10 years ago

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

flavorjones commented 10 years ago

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 commented 10 years ago

@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

natevick commented 9 years ago

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.

plentz commented 8 years ago

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

rgraterol commented 8 years ago

@arnaud036 Thanks bro

flavorjones commented 8 years ago

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.
