[Solved]can not run "sudo ./QtSdk-offline-linux-x86-v1.2.1.run"



  • 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



  • Did you try "chmod a+x"?



  • 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"?


  • Moderators

    "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.
