just an idea : it could be usefull to select a number in a cell with the mouse scroll wheel

anyway, thanks for this apps

Another suggestion instead of mousewheel - I saw a nice number-wheel input system in a flash-based sudoku. See http://www2.hs.fi/extrat/sudoku/sudoku_popup.html and right click in a square.

Amazing app redsh, thanks!!

Some more suggestions - some of these ideas were loaned from (GPLed) G-Sudoku (http://www.yzonesoft.com/gsudoku/gs_buy.html)

1. Pencil-marks should
a) fit the square (especially big resize kills the visibility as the line gets cut in left side) and
b) be sorted (maybe as an option)
2. Option for
a) automatically filling in pencil marks to all non-confirmed squares with all 'legal' possibilities
b) automatically wiping pencil-marks when filling in another square makes them obsolete
3. Simple undo would facilitate solving - the checkpoints are way too complicated for casual solving
4. Possibility to input a puzzle from scratch and get it validated, so while solving the original squares appear as 'solid' not user inputted - I noticed that one can create a text file and open it, but an input function with solvability check would still be great
5. Possibility to have a global custom set of (unique) characters for the puzzles (e.g. alpha sudoku) - this should only affect the display, not for example saving
6. Possibility to set alarm or time limit for the time elapsed
7. I realise that the solving algorithm is generic, but G-Sudoku has implemented set of 'normal' solving techniques which it applies to check the feasibility of a certain set - would be nice as an option

Continuing my own requests after I saw in our local newspaper examples of these:
8) Option to be able to generate/solve XSudokus - not X-rated versions but having the additional rule to have 1-9 once also in both diagonals. Could also highlight the diagonals when one of these diagonal squares is pointed.
9) I think redsh's algorithm would be able to generate overlapping variants of sudoku - e.g (X)Samurai with 5 sudoku puzzles where the middle one shares a corner 3x3 blocks with each of the other four as well as double or triple (X)Sudokus where the overlapping puzzles share four 3x3 blocks with the other(s). See examples in http://www.djape.net/sudoku/wp/?cat=14

Very nice!

This would be a great addition to kde-games :-)

You should first install the dependencies using apt-get:

sudo apt-get install kdelibs4 libqt3c102-mt libqt3c102-mt libstdc++5

Maybe you will have to add some extra package repositories (universe or multiverse), you can find information about this on the website of ubuntu.

This 4 libs have a lot of dependencies too, so prepare for a big install! This is just because you don't have the qt/kde libraries yet.

If people are using the latest version of Ubuntu, 5.10 / Breezy, the following libraries have replaced the ksudoku dependencies:

$ sudo apt-get install kdelibs4
Reading package lists... Done
Building dependency tree... Done
Package kdelibs4 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
kdelibs4c2 kdelibs4-dev
E: Package kdelibs4 has no installation candidate

similarly,

$ sudo apt-get install libqt3c102-mt
Reading package lists... Done
Building dependency tree... Done
Package libqt3c102-mt is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
libqt3-mt
E: Package libqt3c102-mt has no installation candidate

dpkg: dependency problems prevent configuration of ksudoku

(e.g. kdelibs4c2 replaces kdelibs4 in Sid...)

User of debian sid should install from source.

BTW, thanks for this nice app.

At last I found someone who could make me a rpm working on Fedora..

kfries6

THANK YOU!!!

I love this program, and I would keep compiling from scratch. Then when the RPM came out, I would try to switch to it... But it would fail, and leave my original version unusable :-(

Some day, I really do need to learn how to make and update RPM packages.

Again, Thanks!!

Is anyone maintaining a RPM package for this that installs in Fedora?

Fedora install fails looking for

- libaudio.so.2
- libexpat.so.1

Neither of which is available or easily obtainable for Fedora.

Thx

Try rpm rpm -ivh --nodeps ksudoku-0.2-1.i386.rpm

If, at the first run, the window is too small enlarge it.

libidn.so.11
libkwalletclient.so.1

redsh

Try the new Fedora rpm package (see above)!

This does not work! Doing so causes ksudoku to error out with the following message:

ksudoku: error while loading shared libraries: libaudio.so.2: cannot open shared object file: No such file or directory

You've made an excellent app! I also wanted to program a sudoku generator, and you've done just this. The user interface is also nice. Thank you!

Hi, nice game.

But there is a little bug:

After you have solved or let have solved a requester appears.
You close it the first time, everything is ok.
You click "Solve" a second time, and this requester appears in an endless loop, and you have to kill the program from the task manager.

yes! thankies, excellent work, love the game, good to have on the desktop instead of various crappy sites :)
