installation issues

[simontoftnielsen]

Hi,
Spend all day trying to get this to work.
I am running Ubuntu 16.04 LTS on a virtual machine.
I have built poppler using the build_poppler shell script you provided. It ran smoothly!

Running setup.py with the install command however returns the error:
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

Googling suggested me to sudo apt-get a bunch of packages. So I installed/updated:

build-essential autoconf libtool pkg-config python-opengl python-imaging python-pyrex python-pyside.qtopengl idle-python2.7 qt4-dev-tools qt4-designer libqtgui4 libqtcore4 libqt4-xml libqt4-test libqt4-script libqt4-network libqt4-dbus python-qt4 python-qt4-gl libgle3 python-dev libssl-dev python-dev gcc python-dateutil python-docutils python-feedparser python-gdata python-jinja2 python-ldap python-libxslt1 python-lxml python-mako python-mock python-openid python-psycopg2 python-psutil python-pybabel python-pychart python-pydot python-pyparsing python-reportlab python-simplejson python-tz python-unittest2 python-vatnumber python-vobject python-webdav python-werkzeug python-xlwt python-yaml python-zsi python3-dev python3.5-dev libffi-dev

I did not install all of them at once. Just tried a different suggested solutions - and there were a lot...
Anyway. I still can't get it to work. Any suggestions?

All the best,
Simon

ALSO...
I get a lot of warnings saying:
'warning: override controls (override/final) only available with -std=c++11 or -std=gnu++11
I have no clue what this means :-)

[izderadicka]

Warnings are not important only errors. Usual problem is that setup must know where poppler source is. So either use POPPLER_ROOT environment variable or have it in poppler_src under in directory where setup.py script is. If this is not issue then exact compiler error is needed.

@simontoftnielsen I had this problem when i was compiling in centos 7.

I've made a fix in my pip installable branch
https://github.com/oplahcinski/pdfparser/blob/pip-installable/setup.py#L68

In the master branch you can see its empty
https://github.com/izderadicka/pdfparser/blob/master/setup.py#L16

It gives you a ton of warnings about the override but you should see an actual error saying something like "‘nullptr’ was not declared in this scope".

I had GCC 4.8 so nullptr was supported but you have to add that extra compile arg to make it work.

I had the same problem compiling this as a docker image with alpine linux.
@oplahcinski made the correct fix, I did the same and it fixed the problem.

For debugging purposes, these are the compilation errors I got:

Merged PR from @oplahcinski , thanks a lot for that. I'm usually too lazy to make reasonable setup scripts, sorry for that. README is better too, with tested installation recipes .
I'm going for beer now :-) and you are all invited if you'll be near Prague in future.
