AutoQuad Forum

Hi,

I wanted to compile the new version of the GCS for Linux, but again errors upon compiling:
Start: /usr/bin/make -w
make: Entering directory `/home/duke40/qgroundcontrol'
Makefile:2979: Warning: the commands for the destination »build-release/moc/moc_WaypointViewOnlyView.cpp« are overwritten
Makefile:2976: Warning: old commands for the destination »build-release/moc/moc_WaypointViewOnlyView.cpp« are ignored
/usr/bin/uic-qt4 src/ui/qgcautoquad.ui -o build-release/ui/ui_qgcautoquad.h
uic: Error in line 245, column 79 : Unexpected attribute alignment
File 'src/ui/qgcautoquad.ui' is not valid
make: Leaving directory `/home/duke40/qgroundcontrol'
make: *** [build-release/ui/ui_qgcautoquad.h] Error 1
Finished with return value 2.

Any idea what is wrong? I had a look at the file mentioned in the erro qgcautoquad.ui but could not find any error on line 245.

I would really like to use the latest GCS version.

Thanks and best regards,
DUKE40

Hi Duke,

Very strange... you definitely have Qt 4.8.4? You can try the attached, but I have a feeling the error will simply move to a different line number...

How can I check the Qt version used? Is there a command which returns the version like java -version for java?

Hi,

I have checked now the version of Qt instaled and it is the latest available for my Distribution which is 4.4.6.3-4.
No idea how and where I could get the version 4.8.4 for my Linux (Debian Squeeze).

I have removed all attributes alignment in the .ui files and could compile GCS without any problem. It runs also correctly and looks usable.
I will work with it and hopefully most of my issues will be solved

If there's no Debian package for Qt 4.8.4 (I'd be surprised), you'll need to build the Qt libs from source. It's not hard, just follow the instructions.

I read somewhere that if you change your repo to Wheezy (testing), Qt there is 4.8.x.

Hi, I'm on ubuntu, sudo command is succsseful, so is clonning from the link given in the guide:

I can't find the pixhawk or libxbee files/directories at all..
I couldn't pass this bit yet.. can someone help please? also can't load the specified path in Qt creator...

Xbee is in /libs/thirdParty/libxbee. Not sure what you mean about pixhawk... shouldn't be required to build (some of their stuff was moved to /files_unused a while back). In Creator you should be able to just open the qgroundcontrol.pro file.

Hi Max,

In creator, do I need to "create" a project named qgroundcontrol or open an existing downloaded file. If its the later which I assume, I just can't find that file in my system!

Any guess where did I slipped?

Thanks
