Error in compiling QT-5.0 on ubuntu linux
-
[quote author="santhosh" date="1357540123"]hii I got a problem in installing qt5 in linux...
Can any one help me..[/quote]You need to tell us much more than that + it would be nice if you didn't hijack someone's else topic. What errors do you get, which distro are you using, which Qt5 package are you attempting to install/ compile, etc.

im using latest version i.e qt5....
in which I got some errors while installing it.Iam new to QT so I need to develop a project using QT. And one more
thing is that I need to do it in LINUX platform .Iam totally confused
of where to write the code, where to execute the code wether in
terminal or in QT itself.
And I have one more doubt when we open a new window it shows different
options like c++ project,main source prog etc.... My doubt is that
wether the source code is enough or we need to add the c++ main source
code present in the options window.
Please help me......
I dont have any source -

How else can I phrase my request for you to understand that some errors is not enough? When you say that, I simply have no idea what went wrong on your side... so I can't help, even though I do want to.
[quote]Iam totally confused

terminal or in QT itself.[/quote]Yeah, that can happen in the beginning. First, you need to differentiate between Qt libraries (a set of headers, libs, code generators and tools that makes c++ cool, shiny and awesome) and Qt Creator (an IDE that makes creating Qt applications easy). For a beginner (and for most experts, too), it's probably best to start by installing Qt libs, then Qt Creator, and writing code in QtC. It's really splendid tool, I personally find it to be the best IDE ever ;)
You can write code in any text editor, and run it from terminal if you wish, though. I just would not recommend it if you are a newbie - might be a bit too hard at first.
[quote]And I have one more doubt when we open a new window it shows different

wether the source code is enough or we need to add the c++ main source
code present in the options window.[/quote]Although Qt makes c++ development easier, and allows to skip some parts of the language, main() function is still needed. Without it the compiler/ linker will not know how to put the thing together, and where it should be run.
Hope this helps a bit. Ask more if you need to, but please make your questions specific.

rectify my problem... -
Qt installs to root directories, you need to run it with sudo:
@
sudo make install
@As for QtC - either provide that library version, or compile QtC yourself.

what is this error???
Please rectify my problem -
Precompiled package is compiled on Ubuntu. There might be library naming clashes. Compile the stuff yourself or symlink the libraries to cheat the package.

Which package have you downloaded?
-
Tarball or zip?
-
Either a broken download or some nasty Windows conversion bug, it would seem.
This should extract the archive. If it fails, check the checksums, maybe your download is bad:
@
tar -xaf qt‐everywhere‐opensource‐src‐4.7.0.tar.gz
@ -
-
it extracts to a directory named the same as the tarball.
