Running Ubuntu 12.10 and need QT3

**Aydos** · February 5th, 2013

Hello All,

I decided to swap back to Ubuntu at work from Windows.

Some software that I have to sue at work requires QT3.

I cannot find a successful way to get this installed on Ubuntu 12.10.

Anyone have any ideas?

Every time I try to swap to Linux I end up having to go back to Windows and it is frustrating.

I would like to stick it out this time if I can get my software working.

Thanks in advance.

Have you tried...

Code:

sudo apt-get install libqt4-qt3support

I needed qtdmm to read my electrical meter. It also needs qt3. I just grabbed the qt3 library that I needed from the 12.04 repository and used dpkg to install:

libqt3-mt - Qt GUI Library (Threaded runtime version), Version 3
qtdmm - GUI for digital multimeter

So if you know the exact qt3 libraries, just install them. They will sit happily next to the qt4 libraries. I have not used the dummy package suggested by Cheesemill, but that looks like a valid solution as well.

As a side note: qtdmm is being rewritten/refactored to use Qt4, but it is not finished yet. It will be called qtdmm2 when it is released.

And yes, the OP has a good point. Regressions and finding Windows software replacements are serious impediments to linux adoption. Patience and diligience are required to fix regressions and find suitable replacements.

Unfortunately linux contains neither:

tgalati4@Dell600m-mint14 ~ $ sudo apt-get install patience diligence

Does 12.04 have QT3 ?

If so I can drop down to that since it is the LTS anyways.

What are the steps to do it this way?

Also, do you know if I could just run Ubuntu 12.04 lts and resolve the issue.
