install from svn on Linux not working for me

[_C_M]

Thanks, but after installing libfreetype6-dev, I tried to install
matplotlib again and still get a lot of errors. Listed below.

Ouput of install:

basedirlist is: ['/usr/local', '/usr']

My goal is to just get the lastest svn version of matplotlib, or, if
not that, just the 0.99 version, up and working on my Linux (Intrepid

as per the webpage, did:

cd matplotlib
python setup.py install

and that resulted in a very large amount of errors. I'll post them at
the bottom of this message, since there are many lines.

I previously had 0.98.x installed, via the Ubuntu repositories, but I
have uninstalled it. My version is:
Linux ubuntu 2.6.27-7-generic #1 SMP Fri Oct 24 06:40:41 UTC 2008

Any help is appreciated. Thank you,

You seem not to have the development package of python installed.
Try "sudo apt-get install python-dev".

It looks like you are need to install libfreetype6-dev. Any time you
see missing .h files in your output, it means you need to install the
development headers for that package.

As I posted before, I ran across precisely these same errors when
upgrading my Ubuntu box and the Python interpreter. You will need to
install other dependencies as the installation log shows (gtk-2.0+,
pygtk), including its development versions.

And yes, distributing a packaged Python application which uses
Matplotlib (either for Linux or Windows) is *not* an easy and simple
matter. But with patience, it is possible.

Best wishes,

My goal is to just get the lastest svn version of matplotlib, or, if

as per the webpage, did:

cd matplotlib
python setup.py install

and that resulted in a very large amount of errors. I'll post them at
the bottom of this message, since there are many lines.

I previously had 0.98.x installed, via the Ubuntu repositories, but I
have uninstalled it. My version is:

Any help is appreciated. Thank you,

You seem not to have the development package of python installed.
Try "sudo apt-get install python-dev".

It looks like you are need to install libfreetype6-dev. Any time you
see missing .h files in your output, it means you need to install the
development headers for that package.

Darren

Thanks, but after installing libfreetype6-dev, I tried to install
matplotlib again and still get a lot of errors. Listed below.

On Debian/Ubuntu-like systems with apt-get, you can get all of the development headers required for matplotlib in one fell swoop with:

  sudo apt-get build-dep python-matplotlib

As I posted before, I ran across precisely these same errors when
upgrading my Ubuntu box and the Python interpreter. You will need to
install other dependencies as the installation log shows (gtk-2.0+,
pygtk), including its development versions.

And yes, distributing a packaged Python application which uses
Matplotlib (either for Linux or Windows) is *not* an easy and simple
matter. But with patience, it is possible.

My goal is to just get the lastest svn version of matplotlib, or, if
not that, just the 0.99 version, up and working on my Linux (Intrepid
Ibex) computer. I checked it matplotlib out from svn fine, and then,
as per the webpage, did:

cd matplotlib
python setup.py install
            

and that resulted in a very large amount of errors. I'll post them at
the bottom of this message, since there are many lines.

I previously had 0.98.x installed, via the Ubuntu repositories, but I
have uninstalled it. My version is:
Linux ubuntu 2.6.27-7-generic #1 SMP Fri Oct 24 06:40:41 UTC 2008

Any help is appreciated. Thank you,

You seem not to have the development package of python installed.
Try "sudo apt-get install python-dev".
        

It looks like you are need to install libfreetype6-dev. Any time you
see missing .h files in your output, it means you need to install the
development headers for that package.

Darren
      

Thanks, but after installing libfreetype6-dev, I tried to install
matplotlib again and still get a lot of errors. Listed below.

As I posted before, I ran across precisely these same errors when
upgrading my Ubuntu box and the Python interpreter. You will need to
install other dependencies as the installation log shows (gtk-2.0+,
pygtk), including its development versions.

Can someone explain why I was able to have matplotlib 0.99 installed
previously, and can easily have 0.98 installed through Synaptic/Ubuntu
repositories, and yet have to hunt down the additional dependencies
myself if I install from svn? I can't recall if I installed 0.99
through a third party repository or how I got it, but the point is:
is the svn version going to be different than what one gets through a
repository?

Is this need to install dependencies usually the case when installing
from svn?--and if so, can I suggest that this be mentioned in the
online documentation? (perhaps it is and I didn't see it?).

And yes, distributing a packaged Python application which uses
Matplotlib (either for Linux or Windows) is *not* an easy and simple
matter. But with patience, it is possible.

On Windows I've found it is close to easy once you know to include
the matplotlib data files in your py2exe script (also, using GUI2Exe
helps with this a great deal). What are the (basic) steps for doing
this on Linux? I was thinking of using cx_freeze or something to
package everything up on Linux.

Thank you,
Che

With Python 2.5, I have success with bb_freeze (derived from
cx_freeze), however it is not compatible with Python 2.6. I'm right
now investigating PyInstaller (http://www.pyinstaller.org/), which
looks promising.

Hope this helps.

Best wishes,

Because you have to have the development headers available in order to
*compile* the extension code in matplotlib. I tried to make clear in
my previous post that if you inspect the error messages and find
references to missing .h files, that means you need to install the
relevant development packages. In your most recent post, png.h is
missing, so you need to install libpng-dev (or whatever ubuntu calls
the development headers for the png library).

I can't recall if I installed 0.99
through a third party repository or how I got it, but the point is:
is the svn version going to be different than what one gets through a
repository?

Is this need to install dependencies usually the case when installing
from svn?

yes

--and if so, can I suggest that this be mentioned in the
online documentation? (perhaps it is and I didn't see it?).

The information is already available in the INSTALL file in the svn
sources, and I just added a comment which should eventually appear at
http://matplotlib.sourceforge.net/users/installing.html .

When building from source, you also need the header files (*.h files) of all of matplotlib's dependencies. When you install the matplotlib binary package (.deb file), these header files are not installed. Debian, Ubuntu and most other Linux distros separate the compiled binary libraries and header files into separate packages. The latter are usually named the same as the binary package but with a "-dev" suffix.

The "apt-get build-dep" command is designed specifically to install all of the header files required to build a particular package. Therefore "apt-get build-dep python-matplotlib" is a great shortcut to set up your machine for building matplotlib from source.

It sure can -- it was overlooked because this requirement is true of any compiled piece of software, not just matplotlib. Would you like to contribute a paragraph or two? I'd be happy to merge it into the docs.

Michael and Darren (and others),

I've used svn before to download pure Python code, but never to get
anything that needed to be built. I'm fairly out to sea here, so
thanks for the patience.

When building from source, you also need the header files (*.h files) of all
of matplotlib's dependencies. When you install the matplotlib binary
package (.deb file), these header files are not installed. Debian, Ubuntu
and most other Linux distros separate the compiled binary libraries and
header files into separate packages. The latter are usually named the same
as the binary package but with a "-dev" suffix.

That's useful to know.

The "apt-get build-dep" command is designed specifically to install all of
the header files required to build a particular package. Therefore "apt-get
build-dep python-matplotlib" is a great shortcut to set up your machine for
building matplotlib from source.

I did that, and then did the setup.py install and, yes, it now all
works for me (not that you don't know that). I have mpl 1.0 installed
on that Ubuntu machine. (btw, Mauro, thanks for the tip on
Jaunty...I've been having random crashes with Intrepid now and may try
to start anew with Lucid Lynx when it comes out in a couple of weeks).

Is this need to install dependencies usually the case when installing
from svn?--and if so, can I suggest that this be mentioned in the
online documentation? (perhaps it is and I didn't see it?).

It sure can -- it was overlooked because this requirement is true of any
compiled piece of software, not just matplotlib.
Would you like to contribute a paragraph or two? I'd be happy to merge it into the docs.

I can at least try; let me know if what follows is a good approach to
take. The problem I've had today is that I didn't realize one has to
build matplotlib when getting it as source AND that there are a lot of
build requirements prior to installing. All that actually IS on a web
page, but my problem is when I skipped to the "install from svn" link,
I was then on a new page that didn't mention it, and, being new to
building, didn't realize it. And so, my suggestion would be that at
every place (1-3 places perhaps) where the docs mention doing the
following:

cd matplotlib
python setup.py build
python setup.py install

(such as on the "install from svn" page) ...there can be a) a small
note reminding newbies that in order to build you need to have the
build requirements satisfied or else the build will fail with numerous
errors, and in that note b) a link back to the "Build requirements"
paragraph already on this page, here:

http://matplotlib.sourceforge.net/users/installing.html

...and maybe c) the shortcut that you mentioned for Linux users. If
(c) doesn't belong there, it should at least be in the "Build
requirements" paragraph, something along the lines of this:

"Note: if you are building matplotlib on Linux, instead of manually
installing all of the build requirements (dependencies), you can
simply run this command:

apt-get build-dep python-matplotlib

It should take some time to finish, but you will then have built
matplotlib as well as everything needed to have it work. Afterward,
all you need do is install it with:

cd matplotlib
python setup.py install"

I hope this makes sense. I appreciate everyone's help here.
