Qt Quick 3d with the SDK?

  • I am having a bit of trouble getting Qt3d to compile with the current SDK on Ubuntu 10.10.

    I have downloaded the Qt3d preview that is mentioned in the "Labs blog post": and tried to compile it in Qt Creator (2.2).

    When I try to build it I get this as output:

    Running build steps for project quick3d...
    Configuration unchanged, skipping qmake step.
    Starting: "/usr/bin/make" -w
    make: Entering directory /home/sam/Documents/Programming/Qt/qt3d/quick3d-shadow' cd src/ && /usr/bin/make -f Makefile make[1]: Entering directory/home/sam/Documents/Programming/Qt/qt3d/quick3d-shadow/src'

    Error while building project quick3d (target: Desktop)

    Do I need to be recompiling the rest of Qt as well, or is there something I am missing.

    That is the install step, isen't it?

    You will need root permissions to write into /opt. Try "sudo make install".

  • You can install the SDK in your home folder to skip this kind of issues :)

  • Thanks Tobias. Running the build as root worked. I knew it would be a simple solution.

    I think the confusion was from the instructions saying not to run make install as root if you're building Qt itself for Qt/3d. I must've been tired when I read them the first time.

    The demos all look pretty good now I've got things running. I can't wait to get stuck in.
