QT Creator and BeagleBone: Syntax error: newline unexpected

vdavidguerrero

Hi,

I've a few problems trying to set up my developer enovoirment, this is that i've done:

i downloaded the anstrong tool chain from: http://www.angstrom-distribution.org/toolchains/ to my ubuntu 12.04 Virtual Machine.
Run the Environment setup by using ". /usr/local/angstrom/arm/environment-setup"
Download QT Creator 2.8 from: http://download.qt-project.org/official_releases/qtcreator/2.8/2.8.0/

On my BeagleBoneBlack which is running Angstrong Linux and using 3.8 linux kernel i downloaded qt using "opkg install qt4-embedded --force-dependencies".

i was following derek's video guide: http://www.youtube.com/watch?v=kP7uvOu9hoQ and made and example app and "qmake2" in the app's folder and then "make", upload the file to my beaglebone and run in it using ./my_app -qws and it worked!

and now my problems...

First when i tried to create a new "QT GUI aplication" there wasn't any tample more than , Code Snippet , everything under "Non-Qt project" and "Import Project". So i tried to fix by downloading the same Qt creator derek was using so i run the unistall in the qt creator folder and installed the 2.6 qt creator and the same....

Does anybody know why could it happend?

Second, i tough maybe the problem is some library missing so i installed the QT 5.1.1 "Suite" from: http://qt-project.org/downloads "Qt 5.1.1 for Linux 32-bit (417 MB)" and then i solved the problem, now i have more templates whether i'm using 2.6 or 2.8 qt creator.

i run the environment script again and opened qt creator and:

"Create new project" -> applications -> Qt Gui Application.
i create a new kit:
- Name: BeagleBoneKit2
- Device Type: Generic Linux Device
- Device: MyBeagleBone its ip and root password.
- sysroot: empty
- Compiler: /usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-g++
- Debbuger: /usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-gdb
- Qt Version: /usr/local/angstrom/arm/bin/qmake2 (Qt 4.6.3 arm).
- Qt mkspec: empty
i left the detail secction the same, and git as source control.

when i tried to run my app i got: :-1: error: execvp: ../Vincent/mainwindow.ui: Permission denied

so i chmod 777 * in the app's folder.

now everytime i try to build my app i get:

/home/vdavidguerrero/app/down/Vincent/mainwindow.ui:-1: error: 2: ../Vincent/mainwindow.ui: Syntax error: newline unexpected

more detailed:

21:25:26: Starting: "/usr/local/angstrom/arm/bin/qmake2" /home/vdavidguerrero/app/down/Vincent/Vincent.pro -r -spec linux-gnueabi-oe-g++ CONFIG+=debug
21:25:26: The process "/usr/local/angstrom/arm/bin/qmake2" exited normally.

Error while building/deploying project Vincent (kit: BeagleBoneKit2)

and this is how my project's page looks like :http://i42.tinypic.com/2hs9iwz.png
