Hi all, |
| 2 |
I've got the latest portage available, V3.4.1, Qt Creator installed. |
| 3 |
When I go to start up creator, I get a full screen window frame popping |
| 4 |
up, some menu and icon bars around the edge and then, instead of the |
| 5 |
text edit pane, I get a "clear" window, I can see the screens wallpaper, |
| 6 |
and three dialogues popping up. These dialogues are titled "Welcome Mode |
| 7 |
Load Error" and look like the top paragraph of the dialogue shown here: |
| 8 |
http://tinyurl.com/o9ax8ml - yes I know this is for a windows bug, but |
| 9 |
the dialogue is the same. |
| 10 |
|
| 11 |
I've tried to track down on the Qt site what the minimal Qt |
| 12 |
requirements for Creator are but that was useless - can't find it |
| 13 |
anywhere. I then had a look at the Creator ebuild and it says: |
| 14 |
|
| 15 |
# minimum Qt version required |
| 16 |
38 QT_PV="5.3.2:5" |
| 17 |
|
| 18 |
This is where it gets interesting. I have not made the jump to Qt 5, but |
| 19 |
I can remember a large Qt update recently that had "5" bobbing past |
| 20 |
occasionally during the compile process. It was something that I meant |
| 21 |
to follow up but haven't. Doing an "eix qt | grep Installed" reveals |
| 22 |
that I have a mix of 4.8.7 and 5.4.2. Doing "emerge --info | grep qt" |
| 23 |
reveals only "qt3support" and "qt4". No mention of "qt5". |
| 24 |
|
| 25 |
As this is to do with OpenGl, but I actually suspect this mismatch of |
| 26 |
Qt, "eselect opengl list" says nvidia is selected. Re-emerging |
| 27 |
nvidia-drivers also says: |
| 28 |
|
| 29 |
*************** |
| 30 |
|
| 31 |
* >>> SetUID: [chmod go-r] /opt/bin/nvidia-modprobe ...[ ok ] |
| 32 |
Switching to nvidia OpenGL interface... done |
| 33 |
* Removing x11-drivers/nvidia-drivers-352.21 from moduledb. |
| 34 |
Switching to nvidia OpenGL interface... done |
| 35 |
* Updating module dependencies for 4.0.5-gentoo ...[ ok ] |
| 36 |
* Adding module to moduledb. |
| 37 |
Switching to nvidia OpenGL interface... done |
| 38 |
Switching to nvidia OpenCL interface... done |
| 39 |
* USE=tools controls whether the nvidia-settings application |
| 40 |
* is installed. If you would like to use it, enable that |
| 41 |
* flag and re-emerge this ebuild. Optionally you can install |
| 42 |
* media-video/nvidia-settings |
| 43 |
|
| 44 |
*************** |
| 45 |
So it appears OpenGl is good to go. |
| 46 |
|
| 47 |
Does anyone have any ideas as to how I can get back to a "pure" Qt4 |
| 48 |
setup? I've just had a look in /usr/portage/profiles/use.desc and there |
| 49 |
is a qt5 in there. Should I do a "-qt5" in make.conf and a new "emerge |
| 50 |
-NuD world"? |
| 51 |

the section "What USE flags exist" has two links to supposedly online |

description - no they don't. |
