Error in compiling QT-5.0 on ubuntu 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.

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.

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.

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.

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.

Please rectify my problem as soon as possible...

Which package have you downloaded?

santhosh

qt‐everywhere‐opensource‐src‐4.7.0

sierdzio

Tarball or zip?

santhosh

actually it was tarball but it was unable to unzip those file in linux so i have unzipped those files in windows and copied back into linux and installed

sierdzio

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
@

santhosh

ya i have tried this but it is saying that ""permission denined""....
Then i have changed the permissions using chmod command....
After this some unzip process went on and i didnt find the extracted file and it is saying that
""nothing is changed""

santhosh

qt creator was installed successfully but there was some problem with gmake

sierdzio

it extracts to a directory named the same as the tarball.

santhosh

Will be their any problem with Operating System

santhosh

I didnt find any such file or folder
