Problem installing cranvas (specifically install_github('qtbase', 'ggobi'))

[alobo...@gmail.com]

Hi!
I get this error (linuxmint Olivia based on Ubuntu raring) when I try to follow directions in
http://cranvas.org/download.html

I do have all dependencies:
$ sudo apt-get install libqt4-dev qt4-qmake cmake r-base-dev libcurl4-gnutls-dev
Reading package lists... Done
Building dependency tree      
Reading state information... Done
r-base-dev is already the newest version.
cmake is already the newest version.
libcurl4-gnutls-dev is already the newest version.
libqt4-dev is already the newest version.
qt4-qmake is already the newest version.

and have qtbase from cran. 

Also, install_github('qtpaint', 'ggobi')
went on ok, but have the following problem at install_github('qtbase', 'ggobi'):

I'm kind of lost here, don't know what to do. Any help?
Thanks

The download instructions apply only to the version of qtbase in CRAN. The master branch has already moved to Qt5, so those instructions are out of date. You'll need to get the qt5 equivalent of everything.

Michael,
do you know if I can have qt4 and qt5 at the same time? If not, would qt4-based applications be happy with qt5?
I have other applications using qt (i.e. qgis).
Otherwise, may be I rather stay on the cran version,which I assume stable. Is there a link summarizing the differences?

Thanks
Agus

I would just rely on the CRAN version for now. Not everything has been tested with Qt5. That said, both qt4 and qt5 should peacefully coexist on your system.

I have similar issue (Ubuntu). Seems to be similar to http://askubuntu.com/questions/374755/what-package-do-i-need-to-build-a-qt-5-cmake-application.
Do we need qt*5-dev, names?

If you're asking whether you need the -dev packages installed to build qtbase, the answer is definitely "yes".

No, I were not. I felt like the path was not found only. However it was perhaps my fault. Will try to update qt packages...
