Dear Hanchuan and Vaa3d team

I am trying to build Vaa3d on Ubuntu using the instructions on the Github wiki.

I cloned the two repositories and created the symbolic links. I put the provided Qt-4.7.3 in /usr/local and added the export line in .profile and restarted the system. Somehow, upon restart,  a /usr/bin appears before /usr/local/Trolltech/Qt-4.7.3/bin in the environment variable 'PATH', which makes '/usr/bin/qmake' the default. I cannot remove the qmake which has been installed through Ubuntu repositories as it would break many other applications. I got around this by running 'source ~/.profile' before running 'build.linux -j4' in the directory 'v3d_external'. This gave me the following error messages:

I also tried to build it with the QT that I installed through Ubuntu repositories (Qt v4.8.6, qmake 2.01a). Here are some notes. I hope these can help you fix the build/make files so that they use the natively installed QT:

1. In file v3d_external/v3d_main/v3d/v3d_essential.pro, line 161/162, you are trying to initialize QTINST_SHARED_FOLDER for including arthurwidgets.h and shared.pri. On my system, I had to install the package 'qt4-demos' to get these files and they were found in '/usr/lib/qt4/demos/shared'.
2.  On my system the command 'qmake -query "QT_INSTALL_PREFIX"' returns '\usr'. I think you have to appropriately make changes while defining QT_DIR, SHARED_FOLDER, etc in v3d_external/v3d_main/v3d/v3d_essential.pro, line 105-166.

I got the same error as above, when trying to compile vaa3d with the natively installed Qt as well.

Thank you.

Sincerely
Ajay
