Hi,

When building, I get the following build-error:

[ 55%] Building CXX object src/CMakeFiles/koceansaver.kss.dir/ocean.o
/home/hq000006/Downloads/KOceanSaver/src/ocean.cpp: In member function ‘virtual void Ocean::resizeGL(GLint, GLint)’:
/home/hq000006/Downloads/KOceanSaver/src/ocean.cpp:354:69: error: ‘gluPerspective’ was not declared in this scope
make[2]: *** [src/CMakeFiles/koceansaver.kss.dir/ocean.o] Error 1
make[1]: *** [src/CMakeFiles/koceansaver.kss.dir/all] Error 2

I am running openSUSE 12.1, with KDE 4.8 Beta and Qt 4.8 RC. I am not sure if the KDE or Qt versions got anything to do with the above, but it seems as if a certain include is missing.

Thanks

Raymond

You are right it is QT 4.8 not KDE 4.8. They removed GLU intentionally. Here is the link.
https://bugreports.qt.nokia.com/browse/QTSDK-1022

So just add

#include <GL/glu.h>

in ocean.cpp and it should work fine. I will make changes to source soon. Thanks.

Hi,

Thanks for the fast replies. Unfortunately I hadn't access to my computer last night, so I couldn't reply. Yes, KDE 4.8 is currently in Beta.

Fortunately including the statement #include <GL/glu.h> solved the issue.

Thanks

Raymond

Added to source now.

Could it be that kde 4.8 is beta?

did you install package "kdebase-workspace-dev" and "libqt4-opengl-dev"? OpenSUSE may have a little diffident naming standers.

They are indeed called differently on opensuse, but I have all libqt4 and kdebase-workspace packages installed. Also cmake itself does not complain that it doesn't find something.

But as indicated I guess that maybe Qt 4.8 doesn't include something that it did with version 4.7. That is why I was wondering if you would know which include should provide this missing variable ?

Regards

Raymond

Sorry for spelling :( and sorry, I have no idea. I will look and see if I can find anything but if you find something please let me know. Were you able to get version 0.4 to work? if so it may be something with cmake.

Starting to work on it again. New things

1. changed it to cmake now (sould compile on any system now)
2. changed my time basted movement (much faster now)
3. Working on adding Setting Dialog.
4. Adding new fish (remora attaches itself to shark)
5. Adding new fish (Manta ray)

Hope to have thing done soon.

I now using Kubuntu Maverick 10.10, kernel 2.6.35-30
qt4-3.1-amd on AMD64 and for some reason the screen now goes blank and uses up 100% of the cpu. I have dual cpus so one is always at 100% and the computer is almost completely useless until I close KOceanSaver.
What could be causing that?
Will upgrading to Natty 11.04 change that?

Have you try to install KOceanSaver since I converted it to cmake. It should work for you now.

Sorry for getting back so late. What video card do you use?

I packaged this ScreenSvaer for Unity Linux however in testing the package anytime I try and run it it Kills X. Looking into it further when I call the binary /usr/bin/KOceanSaver it comes up in a Window and Dies with:

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Aborted


I'm running KDE 4.4.2
QT 4.6.2
and Unity Linux (a Mandriva derivative)

Make sure you install it. It looks for data files in the installed location. if they are not there then it gives that error.

ls -1 /usr/share/kde4/apps/koceansaver/data/* | wc -l
86

I have 86 files in:

/usr/share/kde4/apps/koceansaver/data/

is that correct?

Yes that sounds right, but this is the error produced when it can not find data files.

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Aborted

I'm kinda new to programing for KDE may be that for different distro it need a different path. Can anyone else help or add anything that might help?

You're right. KOceanSaver.pro hardcodes the install paths, but those can vary between distributions. For instance, it looks like Mandriva is using /usr/share/apps.

To fix it, I'd use cmake instead. Since that's what KDE standardized on, it'd be the best way to make sure that the screensaver uses the right paths, no matter which distribution you're building on.

I installed the screensaver with all required files, but when I try to run the screensaver I get a blank screen and a frozen computer, which I have to force-reboot. How can I uninstall?

Sorry for you problem. I'm not sure, the uninstall should do the trick. try reinstalling then uninstalling again.

Thank you for the screensaver. The ship and sharks are very good. But the ocean surface is a bit fluttering.

And are pictures from data/ocean/ directory unused at the moment?

thanks, i've got the full caribbean sea on my screen

like you say, i add package libqt4-opengl-dev, and all is fine

on debian sid x64

great work

i try to install it on two machine
the first fedora 11 x64

what's wrong


and the second installation is on a sidux (x64), i got same errors like ancleensen4

can you help me

in kde 4.3 they broke off the opengl lib in to own package do a apt-cache search for opengl look for dev kde libs. install that and let me know.

I am trying to install on sidux but get this error after make install;

Any help much appreciated.
