Installation instructions

[iegorval]

Hello,

I find installation instructions extremely lacking. Line you should be able to compile it right away does not tell me anything about versions of dependencies (Qt, C++ standard, compiler) for which I should compile. "Just compilation" fails for me with multiple errors. It would be very helpful if you could extend this README section.

Thanks!
Valeria

Hi Valeria, it's been a while since I last worked on this project. :)
If I remember correctly, I last used C++11, Qt 4.8 (probably), Linux. Can you show me the exact error message you're seeing while trying to compile it?

Hey, thanks for answering! :)

Well, I actually had so many, I have not saved them all. Some were already mentioned in #8, I actually got all of them and tried to fix for my configuration.

I also got multiple errors about setting of actions & shortcuts for each QAction of the menu, as apparently it is not supported in the Qt version I randomly picked (5.4). So I had to rewrite all those to the following format to make code compilable:

mImportGeometryMenu = new QAction("Import geometry...", this);
connect(mImportGeometryMenu, &QAction::triggered, this, &MainWindow::importGeometry);
mFileMenu->addAction(mImportGeometryMenu);

Specifically now I am getting

terminate called after throwing an instance of 'std::bad_alloc'
what():  std::bad_alloc

after selecting .points point cloud. Not sure if sth is wrong with my configuration, code modification, or file itself. Have you seen something like this happening? I am also selecting small downsampled point cloud so that should not be over-allocation of memory or sth like this. Debugger gives me nothing on this one, and I might have to move to starting over with a new Qt version, as now I just really want to see it working :D

Is it supposed to accept files with intensity values or only pure xyz coordinates?
