Building 0.9.3 on Ubuntu 14.04

seanos · 03-11-2016, 01:58 AM

OK, so I’ve made a start but these requirements:

python3.4-tk
python3.4-lxml
python3.4-six

don't appear to be there at all if you use Synaptic. The command line resolves them to:

python3-tk
python3-lxml
python3-six

I think both lxml and six are installed along the way anyway.

Optional plugin requirements
Most of these are OK, but…

There is no Pillow, but there seems to be a fork - python3-pil. It’s not from a standard repo though.

There is a python-cssselect but no python3-cssselect.

It’s a bit unclear from the instructions when you might require these though.

Despite these quibbles, Sigil itself seems to have built OK and it runs. A fairly time- & disk-consuming process (especially downloading/installing Qt!) but it works.

Under Linux some of these Python packages are available as standalone .deb packages others need to be installed via pip3. You can test if you have all recommended packages by installing and running the Sigil test plugin.

As for cssselect and Pillow, try installing them with pip3:

Code:

sudo pip3 install cssselect
sudo pip3 install Pillow

If pip3 isn't found install python3-pip.

I won't pretend that the Linux package names might not stay current. Adjust accordingly. They worked when I created the document (back when python3-* still got you Python 3.3.x on ubuntu/mint), and I always tend to assume that Linux users are fairly resourceful and resilient (as it indeed seems you were

). I'm not going to be chasing exact linux package names, nor updating the documentation every-other week.

The list of additional Python modules needed for a complete Sigil plugin environment are not Linux software package names, but rather, they are the official Python module names useable with pip(3) or easy_install to install from the python.org Python Package Index (pypi.python.org). Since not all Linux flavors use synaptic, I chose to list the additional modules in a distro-agnostic manner. 'pip3 install Pillow' should work on just about any flavor/version out there.

Not being a technical writer, it was never my intention to create a document that someone with no experience with Linux package-management and/or little to no experience configuring/building/compiling software on Linux could use to easily build Sigil with no effort. It is primarily a guide for those with the inclination/knowledge who just need a push in the right direction.

I'm happy to offer assistance, however, when Linux users with questions come here to ask for it. It happens quite a bit, and there are enough Linux Sigil users around here that they rarely have to wait long for help getting it built.

Glad to see you adapted and overcame the document's limitations, though. Seriously. That has always been my hope for a document that--if I'm entirely honest--I hated every second I spent creating.

If anyone wishes to contribute detailed, distro-specific instructions/tips for building Sigil from scratch (or instructions for installing Sigil 0.9.x from distro-specific repositories), I would happily include them in a compendium of user-contributed instructions that I could link to from the BuildingOnLinux document.

I must admit one of my biggest bugbears is the western world’s obsession with binary oppositions and I find the two opposing views of what Linux (perhaps especially Ubuntu) and Linux users should be, rather annoying. Every time I’ve tried to learn things about Python I’ve been put off by the complexity of different versions, the attachment to byte=char and the geek attitude that you can only usefully swallow the knowledge whole. There is no middle ground. It’s all a little like joining a cult.

Once upon a time, Linux was purely the realm of dedicated computer nerds, and that has definitely changed, but reactions to this change seem to be either a) you must learn every technical detail and be absorbed by the collective or b) use a GUI program that assumes you want to know nothing and/or do nothing useful (see Nautilus for a perfect example).

I have done some programming, but I would not call myself a programmer. I still find man pages ugly and tedious to pore over, but what you can do with all those bits and pieces is pretty impressive. So I consider myself to be in that middle ground of users who primarily want to do things other than programming with their OS, but are prepared for a bit of scripting, etc. to get where they want to go.

I don’t consider building from source itself to be particularly difficult. A bit tedious, yes. It’s providing useful, coherent instructions that’s the hard part and I think you did that very well for the most part.

It did occur to me that those packages might involve using pip, but since it continued on from a discussion of Debian packages it wasn’t clear. I also had some bad experiences the last time I used pip.

It’s always great to find helpful Linux users, but clear documentation is still better than time spent searching forums.

Thanks for your assistance, Doitsu.

No problem with cssselect, but I get errors with Pillow.

Spoiler:

When I tried to install the test plugin using your link Sigil tells me “Error: Plugin not a valid Sigil plugin.” The version in the source zip installs OK and reports that everything is fine except, of course, “Python Package: PIL Missing”.

That's a known issue. Pillow requires libjpeg and zlib.

Look for the following packages (or similarly named ones) in Synaptic:

Code:

libjpeg8-dev 
zlib1g-dev

seanos · 03-12-2016, 03:05 AM

Thank you - installed.

DiapDealer · 03-12-2016, 03:35 AM

I DO need to add a note for the libjpeg and zlib pre-reqs for Pillow. That's come up a few times now.

I missed this. It seems that github is not very good at allowing single files from an repository to be downloaded. Right-clicking on the plugin file and using you browser's "Save as" feature will result in an invalid zipfile. Left-clicking the file and then clicking the "Raw" button will download the zip file correctly. I'll change the link if possible, or remove the link entirely and just replace it with instructions to retrieve it from the source archive.

I'm intrigued by "the attachment to byte=char". What do you mean by this, and why does it put you off?

As a general rule of thumb, the dedicated nerds have already done the job of packaging most useful software.

People who want to build from source anyway, should have a basic knowledge of the pitfalls and be able to figure out how to resolve likely errors. For instance, matching python modules to pip/apt.

As you say, useful instructions are difficult. The best way is by example -- for instance, maintaining a packaging script (or just looking at the one the various distros have used to package the software).

Granted, I have never been able to figure out how debian's build system works

but I have always found Arch Linux quite simple and easy to understand in that respect. (In fact, I maintain the Arch User Repository package for sigil-git).

Debian also has that terrible habit of splitting development headers from packages, making it much harder to resolve build dependencies.

For instance, your issue with building Pillow is because of split development and end-user packages.

IMHO Debian is not the best distro for building things from source.
