Dependencies and compilation problem Ubuntu 12.04 #142

Closed atomic closed 10 years ago

My elementaryOS(based on Ubuntu 12.04 Precise) does not have the access to Trusty, so i have to install Qt 5.3.1 from http://qt-project.org/downloads and added the correct path to the qt bin folder. "sudo qmake -v" gives me (i install it on /opt/ so i use sudo):

QMake version 3.0
Using Qt version 5.0.2 in /usr/lib/x86_64-linux-gnu

Here's the error i get when run "sudo make":

cd app/ && ( test -e Makefile || /usr/lib/x86_64-linux-gnu/qt5/bin/qmake /opt/cool-retro-term/app/app.pro -o Makefile ) && make -f Makefile

make: *** [sub-app-make_first] Error 2

But Qt 5.3.1 has QtQml, which is at /opt/Qt5.3.1/5.3/gcc_64/qml

So, how to resolve this?

Ok, you did the right thing getting Qt directly from Digia. The problem here is that you are not using them, "qmake -v" should return something like "Using Qt version 5.3.1 in /opt/Qt5.3.1/5.3/gcc_64/".

I think the issue here is that you are running everything with sudo, which if I recall correctly restores some environmental variables to prevent security attacks. To be clear you don't need to use sudo to use the version of Qt in /opt/. sudo is not giving you the right to use them is giving you the right to modify them (which you don't need).

Oh my, i didn't know root has different access to different qmake. Yeah, i compile it somewhere else with no sudo, and it worked. I wonder why my root has very old version of qt which i never installed. Thanks, it worked really well.
