QT50-Snapshot on Raspberry Pi

DarkRidder

That sorted out right, but then, another error and this one I could not fix:
While making it, got this error:

I tried to ignore it, but on the install got this one:

Any advice on this?

SGaist

Run make without -j to get the error

DarkRidder

Same:

[EDIT]: I have run just "make" to get to that error.

SGaist

It makes it more readable and ensures that you don't have several errors in parallel.

Anyway, I wasn't hit by that one, however, replacing DISPMANX_TRANSFORM_T by VC_IMAGE_TRANSFORM_T should be enough in that case

DarkRidder

THank you, all sorted out right now I think! Now doing dd to the sdcard. After I plug it in RPi, I assume that qt is all set up, so if I run qt on terminal it will recognize it, right?

SGaist

What do you mean by run Qt on terminal ?

Since you cross-compiled Qt, you should start Qt Creator, Go to the Preferences, in Build and Run add your newly built Qt, make a kit using it. Add a Generic Device in devices and connect it to the Rasberry Pi.

Then create a default application that you'll configure with your Raspberry specific Kit, build, run and enjoy !

DarkRidder

Ok, but I need to compile a program that makes use of Qt to run in RaspberryPi, how can I do that?

SGaist

That's what the last paragraph describes, just start a new default project, select your Raspberry Kit, hit the run button which will trigger a build and start the application on the Pi (if you correctly add the device in the preferences)

DarkRidder

ok, so first things first, How do I do all that? What manuals can I read? I am using Ubuntu (and sorry for my noobish knowledge on this, going for Qt for the first time, and it's not being an easy ride! ).

EDIT: I don't have any Qt environment set-up!

SGaist

You don't have Qt Creator installed ? Then you should go and download the Linux package and install it.

Then go through Qt's documentation/tutorials/examples

DarkRidder

SGaist, afte rall, there was something wrong with qmake.

Suggestions? I tried again sudo make install on qtbase folder, but reported this:

[EDIT] Also, error output while trying to build:

SGaist

Did you mount your Raspberry Pi fs ?
