Place in a folder called Phone
Enter that folder in your file manager and right click on the file and select to extract here.
That should show a folder called tuxcall-0.5
Enter into that folder.
Read through the README and the INSTALL files ... they are plain text I think.
Do not click on other files.
If you are using Konqueror as your file manager then goto Window on the top bar, click it, and down near the bottom of the dropped down list select "Show Terminal Emulator".
That will give you a terminal at the bottom of your filemanager's page, and the terminal will always be open in the same location as the file manager.
You are now ready to build the package for your PC.
In the terminal below, while the file manager is still in the tuxcall-0.5 folder and showing the README and INSTALL files do the following in the terminal ...../configure
when this process is finished and you are back at the prompt domake
When this finishes and the prompt is showing you must get root privileges so dosu
<enter> and when the next line shows enter the root password which is not displayed for security reasons.
You should now have root prompt, and so you entercheckinstall
This will build an RPM package for you to use to install and uninstall.
Things you may need
1. Install checkinstall through Synaptic
2. Install Kpackage through Synaptic
Those two may already be in your install, I don't know, but you will need them so install those first.
The process above will tell you where the new RPM is located and Kpackage will allow you to install it.
Kpackage has a facility to Test install the package which you should use first .... if there are difficulties then they should show then.
The only other thing that might catch you is if tuxcall has some dependencies and you have not installed them. You will usually get an error letting you know what the required package is .... install it through Synaptic and try again to build the RPM.
That is about it as I remember it.
It is much easier if you can afford the wait, to ask someone of the packagers/dev team to build it for you and make it available through Synaptic.
You will of course be aware that installations with such packages that have not been vetted by the dev team cannot be properly supported on the forum.
