Problem installing Qt Online Installer for Linux 32-bit on Ubuntu

[sierdzio]

@
sudo apt-get intall build-essential
sudo apt-get build-dep qt5-qmake qt5-default
@

Bit unpleasant such a glitch should hit a newbie :/ If it is the same bug as before, then it's sometimes enough just to repeatedly try running the file, it will work eventually.

sudo apt-get build-dep qt5-qmake qt5-default downloads and make a lot of output. As far as I can see with no error.

The other one seems to be fine too:
@
user@user-D3220-B1:~/Downloads$ sudo apt-get install build-essential

build-essential is already the newest version.

But still getting the same error. Also repeating several time does not help.

Try the offline installer, then.

I would suggest building from source, but I don't want to put that burden on you yet, when we still have other options.

Same error:

@
user@user-D3220-B1:~/Downloads$ ls
qt-linux-opensource-1.4.0-2-x86-online.run qt-linux-opensource-5.1.1-x86-offline.run
user@user-D3220-B1:~/Downloads$ chmod 755 qt-linux-opensource-5.1.1-x86-offline.run
user@user-D3220-B1:~/Downloads$ ./qt-linux-opensource-5.1.1-x86-offline.run
bash: ./qt-linux-opensource-5.1.1-x86-offline.run: No such file or directory

What happens if you run it from the GUI (click/ double click)?

[rubikon]

Nothing happens when I double click on it.

[sierdzio]

This is bad. I'll ask on the mailing list, maybe there are some known solutions.

[rubikon]

Hopefully it helps. Thank you in advance.

Hi,

Is your machine 64 bit ?

[tjenssen]

please show us:
uname -a

and:
ldd /Downloads/qt-linux-opensource-5.1.1-x86-offline.run

Maybe there is a missing dependency to start the installer UI.
a possible fix is:
sudo aptitude build-dep libqt4-opengl-dev

and yes if you have a 64bit system you need a 64bit installer.

PS: Please check that my possible fixing command does the right thing for you, I am not working on linux daily.

[rubikon]

Yes, it is a 64 bit machine.

sudo aptitude build-dep libqt4-opengl-dev seems to run fine but the problem remains the same...

The 64bit installer seems to work. It is currently running. Is it not possible to use and build 32 bit on a 64 bit machine like it is possible on windows?

[sierdzio]

As Thiago mentions in the ML, you may be missing the ia32-libs package.

Running 32 bit applications on a 64 bit Linux system is possible.
