Hi guys,

I wanna install qtsdk, I issued chmod u+x QtSdk-offline-linux-x86-v1.2.1.run
and then I issued sudo ./QtSdk-offline-linux-x86-v1.2.1.run.

nothing happen or prompt a message "no such file or directory", welcome
any ideas

goetz

Did you try "chmod a+x"?

pmjz

yes, i did.but the problem is the same. bash:./QtSdk-offline-linux-x86-v1.2.1.run: No such file or directory

I would guess that you are running a pure 64bit userspace and are trying to install a 32bit application on that.

Took me ages to figure that out when this happened to me the first time: The error message is absolutely confusing there.

great.I just check my system information: ubuntu 64bit. yes, I try to install 32 bit QtSDK

You can either install an additional 32bit userspace then and install the SDK afterwards...

thanks, by the way, what is "32bit userspace"?

tobias.hunger

"userspace" is everything outside the kernel space:-)

As you know most applications depend on libraries to provide functionality that they use. To run 32bit apps on a 64bit system you need all the libraries needed by those apps in a 32bit version. Of course you also need all the libraries those libraries need, etc:-)

Most distributions offer a way to simple way to install a pretty complete set of 32bit libraries on a 64bit linux. Check the documentation/wikis of your distribution of choice.
