need help for c++ programming.

[chinmay3]

I am trying to learn c++. I installed build-essential. I have read some documentations about it. i tried the same way as mentioned in documentation but when i save gedit file of source code i get following error....... (gedit:3838: GLib-GObject-CRITICAL **: g_object_ref: assertion `object->ref_count > 0' failed Is there anyone who know how to resolve this problem? Thanks in advance.

There is an excellent area, a sub forum, for help with these kind of problems called Programming Talk. Maybe a nice mod will move this post there.

In the meantime, please provide more info about your development environment and your error message. Have you had success doing any coding? Did the typical first program, "Hello, World" work? Show us the code that's not working - post code in code tags - and copy exactly the commands you're using to compile and run the code and the error messages you're getting.

Good luck, and keep coding!

Thread moved to Programming Talk.

I don't really see why reports of bugs in gedit/glib need to be moved to Programming Talk, unless you are wanting help in fixing gedit/glib, and as you are just learning that would be somewhat ambitious!

From reading the many similar posts in other forums, these messages are due to relatively unimportant bugs in gedit/glib. Here's one of many http://ubuntuforums.org/showthread.php?t=1264420

Does your file save? If so, don't worry about it, or run gedit from the menu rather than the command line when you won't see the message.

If these messages are a a real problem for you, then simply switch to one of the many many alternatives to gedit: vim, emacs, Geany etc.

Can you please show us your source code ?

Also, to begin you should use an IDE. I suggest you install CodeLite from Synaptic. It's much easier than writing text files, because:
* when compiling and linking with g++, it outputs errors so you can click on them and it will point you to the corresponding line of code
* you can then run your program in debug, doing a step by step execution (using F5, F9, F10, F11 keys, just like in MSVC)

I strongly suggest you start coding in plain C. Only when you fully grasp the subtilties of C should you attempt to learn C++.

Build essential shouldn't be necessary for taking your first steps with C++. Just g++ and gdb should be sufficient, and maybe boost as well. Which documentation did you read. I think if you're really serious about this, getting an hardcopy book should prove very useful. Two of the best are 'C++ Primer' and 'The C++ Programming Language.'

As for your gedit assertion, it seems to be a bug in your version gedit/glib. One way is to try compiling and installing gedit from source. Also ensure that you've applied all the latest updates offered by the update manager. Does this happen when saving any file, or only under some circumstances?

Anyway, in the interim, to get work done, use another editor like GVim or Kate.

How are you calling it?

g++ test.cpp -o test

That error message is completely irrelevant... You're free to report that bug in Gedit, but chances are high that it already was

No, please... The sole fact that you describe the use of keys as an advantage of IDEs reflects my opinion on them: they're not for beginners who still don't know the concepts behind the programming process, but for people that already know them and need an environment that displays all sort of needed tools in a single place (but knowing how to fix stuff manually when something fails).

I strongly suggest you start coding in plain C. Only when you fully grasp the subtilties of C should you attempt to learn C++.

Well, I'd suggest Python before C or C++, but that's another discussion. So, if the alternatives are C and C++, well, I'd go for C, then some unrelated OOP language (whatever: Python, Ruby, Common Lisp, even Smalltalk-80!) and then C++, so that you appreciate the STL (but so that you also don't adore it neither consider it the best thing in the programming universe...).

chinmay3,

See what you've started? Not your fault, obviously.

Please post your code and the tutorial(s) or book(s) you're using to start your C++ journey, and let's get you on your way, out of the middle of this argument. If you need a learning resource, check out the stickies.

this is why i am in love with Ubuntu. The community, lots of helping hands to pull you out of trouble , whoever you are, wherever you are. Thanks everybody. lets come to the point. here is link of page what i have followed.: http://www.ubuntugeek.com/how-to-ins...c-program.html I done exactly same as there written. I have little experience with 'c' programming but its with turbo c compiler on windows xp. Yes the file get saved even after error. I regularly update my system.
