Troubles building on Ubuntu 18.04
I get the following error when building:

fatal error: arthurwidgets.h: No such file or directory

I downloaded precompiled QT 4.7.3 and believe I have correctly indicated to use this version, though I cannot confirm that I did this properly.

Any help would be greatly appreciated!

RE: Troubles building on Ubuntu 18.04
Hi,

Could you please ensure there is an arthurwidgets.h file in your Qt folder? Normally it should be placed at  /usr/local/Trolltech/Qt-4.7.3/demos/shared. 

If it does exist, please make sure you include it in your /v3d_external/v3d_main/v3d/v3d_essential.pro file as: 
SHARED_FOLDER = $$QT_DIR/demos/shared #for arthurwidgets

Also please type which qmake in your terminal and check the default Qt version and path, which is supposed to show:
/usr/local/Trolltech/Qt-4.7.3/bin/qmake
in case there are multiple Qt versions in your pc and it chooses an incorrect one for building vaa3d.
