When you build python3 form sources, it's installed in /usr/local. There is no risk of conflict.

yes i've clicked the add button. It shows http://i35.tinypic.com/2w5ooc6.jpg

selec tfull set of sources

As of now it shows http://i35.tinypic.com/2sbkihd.jpg. Anyway i'll try later and get back to you.. For this do we need to insert the mandriva DVD??
One more ques. is is there a way to embed images in posts?

I don't know how to solve the mirrorlist problem. Normally you dont need to insert the DVD, but if you insert it I don't think it hurts.
You can attach images to posts.
I soon must go for a few hours, so good luck.

thanks Gribouillis for your reply.. Even just before i tried and the mirrorlist problem exists.. Can it be the problem with proxy server? Coz i'm accessing the internet through proxy server..
Is there any other way to solve this problem or this is the only way???

Sorry if i offend you by the following words.. But your answers are way too short like yes/no answers.. I've asked how to embed the posts in images? You've said only yes as the answer and my next ques. will obviously be how it can be done? If u hav given a link to the tutorial or if u've explained briefly it'll save time and effort for both of us.. Try to give some explanatory answers. The explanatory answers 'll solve lot of unknown problems(or answers unknown ques. even before it is asked) and these kind of answers will be liked by all avid learners.. waiting for your reply..

If you want a link to a tutorial, here is one. You should browse the mandriva documentation and use google too, I'm a Mandriva user, but I'm not a Mandriva guru.

Now, about attaching pictures to posts, when you click on the big yellow button "Reply to this Thread" below, the editor widget which appears to edit your reply has a paper clip icon named Attachment with which you can attach a picture.

Sorry dude don't take this in the negative sense(Coz i can see a little disappointment from ur reply). I've been the member of many forums.. In those forums if u want to embed the pics. inline(not as attachment) we have to wrap it around the quotes [IMG]....[/IMG]. But here it's quite different.. I've google around and couldn't find out how in daniweb.That's why i asked..(You could see my previous pics. were posted in this format). Thanks for the info. mate. It'll be really useful for me as the picture says more than words.. If the users send their problems as screen shots it'll be more easy for people like you(geeks) to figure out and find the solution..
One more thing my friend have updated sources in s/w config. in his home connection where it'll be free from proxy hiccups. I'll try this in my home and 'll tell you the result.. Meanwhile if u got some ideas don't forget to tell me.. After all life is all about sharing.. Thanks & regards..

Sorry Gribouillis... just now i noticed that i haven't installed python in /usr/local i've installed in the directory itself.. Will that be the cause of the problem?......
