The issues #2087 and #3732 seem related.

It works in Python 2.7. The dependencies are exactly the same for 2.7 and 3.4. Here is the build script:

$ hit show python3.4.linux.yaml script matplotlib
set -e
export HDIST_IN_BUILD=yes
export CPPFLAGS="-I${BZIP2_DIR}/include -I${FREETYPE_DIR}/include -I${NUMPY_DIR}/include -I${PATCHELF_DIR}/include -I${PKG_CONFIG_DIR}/include -I${PNG_DIR}/include -I${PYTHON_DIR}/include -I${SETUPTOOLS_DIR}/include -I${ZLIB_DIR}/include"
export LDFLAGS="-L${BZIP2_DIR}/lib -Wl,-rpath=${BZIP2_DIR}/lib -L${FREETYPE_DIR}/lib -Wl,-rpath=${FREETYPE_DIR}/lib -L${NUMPY_DIR}/lib -Wl,-rpath=${NUMPY_DIR}/lib -L${PATCHELF_DIR}/lib -Wl,-rpath=${PATCHELF_DIR}/lib -L${PKG_CONFIG_DIR}/lib -Wl,-rpath=${PKG_CONFIG_DIR}/lib -L${PNG_DIR}/lib -Wl,-rpath=${PNG_DIR}/lib -L${PYTHON_DIR}/lib -Wl,-rpath=${PYTHON_DIR}/lib -L${SETUPTOOLS_DIR}/lib -Wl,-rpath=${SETUPTOOLS_DIR}/lib -L${ZLIB_DIR}/lib -Wl,-rpath=${ZLIB_DIR}/lib"

${PYTHON} -c 'import setuptools; __file__="setup.py"; exec(open(__file__).read())' \
   install \
   --prefix=. --root=${ARTIFACT} \
   --single-version-externally-managed

And I used the 1.4.2 tarball: https://downloads.sourceforge.net/project/matplotlib/matplotlib/matplotlib-1.4.2/matplotlib-1.4.2.tar.gz

And I use linux (RHEL6), though we build all the dependencies ourselves.

The text was updated successfully, but these errors were encountered:

tacaswell · 2014-12-04T19:42:03Z

Do you have libpng installed?

Something funny is coming out of status, output = getstatusoutput("libpng-config --version") (output gets assigned to version which is passed to the offending function). It works on python2 because strings and ints can be compared (via id which is not super useful), but they are not comparable in 3.

certik · 2014-12-04T19:54:23Z

I do, this is what I get:

$ python3.4.linux/bin/libpng-config --version
1.6.6

certik · 2014-12-04T19:56:56Z

But during the build it returns b'1.6.6', so that must be it.

tacaswell · 2014-12-04T20:01:51Z

I wonder why this does not blow up on travis...

This is yet more issues with unicode vs bytes.

certik · 2014-12-04T20:04:12Z

I think I found it. We install our own libpng package, but for some reason libpng-config during the build is executed from /usr/bin/libpng-config and that one returns things like:

[matplotlib] b'"/local/certik/bld/png/q24b4y6ojqdw"'
[matplotlib] b'1.6.6'
[matplotlib] -lpng12
[matplotlib] b'"/local/certik/bld/png/q24b4y6ojqdw"/lib'

So that's complete garbage. It's probably related to the fact that we use pkgconf: http://rabbit.dereferenced.org/~nenolod/distfiles/pkgconf-0.9.6.tar.bz2, instead of the usual pkg-config.

In any case, let's see if I can fix this.

certik · 2014-12-04T20:18:55Z

@tacaswell I found it!! This patch fixes it: hashdist/hashstack@0aa2605, what happened was that we were putting our own wrapper on top of pkgconf so that we can insert Hashdist variables into it (things like fixing rpath issues), so that matplotlib and other packages can pick it up properly. But that wrapper didn't work properly in Python 3, which was then messing up Matplotlib.

So this issue is fixed, it's unrelated to matplotlib. But I still think the error message might be more descriptive --- maybe you can check that the answer makes sense?

certik · 2014-12-04T20:19:48Z

Thanks for your help, this would take me a lot longer to figure out without it.

tacaswell · 2014-12-04T20:24:13Z

The explanation makes sense.

I would argue that the real problem is in distutils. We are using distutils.version.LooseVersion to make the versions comparable and I think we should be able to assume that whatever it gives back will be comparable.

certik · 2014-12-04T20:28:25Z

Ah I see. Yes, indeed.

Quite frankly, I just use cmake for my projects and I handle Python installation from cmake. Then I don't have any of these issues.

tacaswell · 2014-12-04T20:39:20Z

Yes, but then you have all manner of cmake issues 😉

Your projects won't (might not?) play nice with other people's setup.py/pip/requirements.txt/venvs. I had an absolute bear of a time trying to get peoples cmake built python packages (ITK) to play nice with virtual environments.

Of course the solution to that is hashdist/conda (which at least in the case of conda were created to deal with this pain).

certik · 2014-12-04T20:48:55Z

Exactly, the same for Hashdist.

I think it is possible to make cmake play nice with pip, e.g. here we test that at least pip install . works with cmake: https://github.com/sympy/csympy/blob/master/bin/test_travis.sh#L52. One just needs to test the various combinations. What I like about cmake is that you just have this Python "wrapper" (https://github.com/sympy/csympy/blob/master/setup.py) that can be fragile, but underneath is a robust system (cmake), to which you tell exactly where to find things and if it can't find it or something fails, you get a reasonable message.

Does the same happen with 1.4.3?

That very unhelpful error is saying that you do not have freetype-dev or
pkg-config installed (that is the version check it is failing on abs the
two most common reasons for the discovered version to come back as a
string).

hahaha, I found out why its failing...

    self.version: ['grep', ': ', 'warning', ': GREP_OPTIONS ', 'is', ' ', 'deprecated', '; ', 'please', ' ', 'use', ' ', 'an', ' ', 'alias', ' ', 'or', ' ', 'script', '\n', 'grep', ': ', 'warning', ': GREP_OPTIONS ', 'is', ' ', 'deprecated', '; ', 'please', ' ', 'use', ' ', 'an', ' ', 'alias', ' ', 'or', ' ', 'script', '\n', 'grep', ': ', 'warning', ': GREP_OPTIONS ', 'is', ' ', 'deprecated', '; ', 'please', ' ', 'use', ' ', 'an', ' ', 'alias', ' ', 'or', ' ', 'script', '\n', 'grep', ': ', 'warning', ': GREP_OPTIONS ', 'is', ' ', 'deprecated', '; ', 'please', ' ', 'use', ' ', 'an', ' ', 'alias', ' ', 'or', ' ', 'script', '\n', 'grep', ': ', 'warning', ': GREP_OPTIONS ', 'is', ' ', 'deprecated', '; ', 'please', ' ', 'use', ' ', 'an', ' ', 'alias', ' ', 'or', ' ', 'script', '\n', 'grep', ': ', 'warning', ': GREP_OPTIONS ', 'is', ' ', 'deprecated', '; ', 'please', ' ', 'use', ' ', 'an', ' ', 'alias', ' ', 'or', ' ', 'script', '\n', 2, 5, 3]
    other.version: [2, 3]

So I have GREP_OPTIONS in my bashrc and that is deprecated, and I guess the way you are executing the command its catching those warnings as well.

sontek · 2015-04-16T22:14:51Z

Installation worked after I did:

unset GREP_OPTIONS

My grep looked like this before:

$ grep '192' foo.txt
grep: warning: GREP_OPTIONS is deprecated; please use an alias or script
grep: foo.txt: No such file or directory

tacaswell · 2015-04-16T22:18:44Z

That is new and interesting. I don't think there is much we can do about
that except make the exception more informative.

Sorry for the version confusion, I read 1.4.2 not what you actually wrote.

@tacaswell Could you send stderr to dev null like:

grep 2>/dev/null

and only grab stdout?

Having same issue - Python3.5.0a3 (dev) / Mac OSX

@ben-albrecht Can you make sure that you have freetype installed. Alternatively try the master branch we recently fixed a bug in the version comparison only happening when freetype is not found

ben-albrecht · 2015-04-21T17:03:46Z

@jenshnielsen Thanks for the suggestion. The latest version from master branch gives a more helpful error message

* The following required packages can not be built:                                                                                                                              * freetype, png

I Installed Freetype via homebrew and pip installed matplotlib from via pip install git+https://github.com/matplotlib/matplotlib - everything works fine now.

I'm seeing a similar failure in debian unstable:

and that line seems to refer indeed to freetype, but running -ftversion i get:

2.6.3

any idea what might be going on?

tacaswell · 2016-09-01T19:47:28Z

do you have pkgconfig installed?

sandrotosi · 2016-09-02T05:59:31Z

yes pkg-config is installed (at version 0.29-4 if that's useful to know)

tacaswell · 2016-09-02T11:41:29Z

@sandrotosi can you open a new issue for this?

sandrotosi · 2016-09-02T18:51:09Z

i rebuilt the packages just to be sure (i had a suspect, reading this bug, it might have been due to a library (fakeroot) that was generating symbols errors and thus messing up with the versions gathering) and it was a transient error, which is now over - sorry for the noise

archenroot · 2017-12-05T16:43:32Z

Ok, guys as soon as on one system the error did not appear and on other did I compared libs and found issue, there were missing:

libpng
libpng-devel
freetype
freetype-devel

Is Python really that stupid or it is due to how matplotlib is managed? If I miss library I screem I am missing that library, so user can install it.... this is detective work...

tacaswell · 2017-12-05T17:13:40Z

The error you are getting is in the logic where we are trying to tell you that there are missing libraries.

You are trying to build no longer supported versions of Matplotlib on an old version of python. I believe we have fixed all of these issues in the current versions of Matplotlib with up-to-date python.

archenroot · 2017-12-05T18:03:49Z

I know, this is some software we received from vendor to install in our environment, not much to do. Apps are developed and used without update for years...

When I am in Java and miss some library it tells me: you are missing this library FULL NAME of class, so...

But ok, I know this is old thread... thx for answer anyway.
