[Solved] Qt Creator installation on linux machine

[pkj__]

I am used to work on windows. However, while trying to install qt creator by downloading the bin of version 2.5.2 gives error:
bash: cannot execute binary file.
Here is what I did.
Downloaded 64 bit bin file from qt.nokia.com of 2.5.2
Opened terminal.
sudo chmod u+x qt-creator-linux-XXX-2.5.2.bin
ls -lb
-rwxr-xr-x 1 z5linux z5linux 83964198 Sep 5 11:29 qt-creator-linux-x86_64-opensource-2.5.2.bin
z5linux@z5linux:~/Downloads$ ./qt-creator-linux-x86_64-opensource-2.5.2.bin
bash: ./qt-creator-linux-x86_64-opensource-2.5.2.bin: cannot execute binary file

...
Any idea what I'm doing wrong? And how can in install?

Are you the z5linux user in that machine?

Is /home mounted with noexec (some people do that;) Are you running a 64bit userland? Does the output of "file /bin/bash" and "file ~/Downloads/qt*.bin" match up?

@stuk,@Tobias: Yes it was a 64/32 bit mismatch. Thanks

The error message for 64/32bit mismatches are really misleading in linux IMHO.
