undefined symbol: _ZTI12QCPFinancial

Hi Dimitry,

When I try to import qcustomplot i get the error undefined symbol: _ZTI12QCPFinancial. I did make some adjustments to configure.py (f650117) to get the build working on Kubuntu 15.04 with Python3. I also symlinked from libqcustomplotlib.so to libqcustomplotlib.so.1.2. I'll keep digging but any chance you have had such an issue when working on this?

You can see my boring build log below.

Cheers, (and thanks for sharing this)

:[ Nevermind. As soon as I typed the 1.2 above I realized it. The financial stuff was introduced in 1.3.0. I had 1.2 because that was what was available in the Kubuntu repos. Downloading and building the latest shared library made it work fine.

Sorry for the interruption...

Or maybe not. Heading to bed but the next issues is undefined symbol: _ZNK11QCustomPlot15plottableBarsAtERK7QPointFb.

$ c++filt _ZNK11QCustomPlot15plottableBarsAtERK7QPointFb QCustomPlot::plottableBarsAt(QPointF const&, bool) const

What version have you built QCustomPlot-PyQt5 against?

Thanks.

Eventually I realized that your repo has a modified version of QCustomPlot 1.3.1 defining a couple extra functions. Once I reverted this (c2795da) to match the git checkout of QCustomPlot I used to build the libraries I was able to import qcustomplot without errors. With this I successfully created a plot window with data. Now to learn QCustomPlot itself.

Thanks again.

Thank you for request. Yes, I modify default QCustomPlot library, because I need in my Python project. Sorry, that I saw your comment just now. Thank you!
