INSTALLING ON MAC 10.6.8

hskoglund

It's tricky with 10.6.8. You sure you cannot upgrade to Mountain Lion or Mavericks?

GreyJay

Hi hsk...
I'm working on a company computer, and I'm not sure if they want to upgrade this machine...apparently they are experiencing issues with Mountain Lion and Mavricks...

Hi and welcome to devnet,

What version of Xcode have you installed ?

GreyJay

Thanks devnet.

I'm running Version 3.2.6 (1761)

SGaist

A bit old…

Also, can you show an example to the error message you got while installing ?

GreyJay

Certainly...

The component installation dialog box:
!http://engineeredvisions.com/qt/Components.gif!

The error during installation:
!http://engineeredvisions.com/qt/Error.gif!

And the error when doing the first run/execution:
!http://engineeredvisions.com/qt/GoToError.gif!

Should I upgrade my Xcode immediately?

Thanks again,

SGaist

Just remembered something: installing 5.2 and onward might have been dropped for 10.6 (however you can still create application that will run on 10.6)

What you can do if you can't update your OS, is to build Qt 5.2 directly on 10.6, AFAIK that is still supported.

GreyJay

SGait,
Which older version should I install, if 5.2 is not accepted on my system? - J

SGaist

IIRC the latest in the 5.1 series

But you should really consider building 5.2, it's not really that hard on OS X and depending on your needs, you don't have to build every module

GreyJay

I'd love to, SGaist. I just can get past these errors during installation and run :(

SGaist

Then just download Qt Creator, and the 5.2.1 sources from there you should be able to build Qt and use it in Qt Creator (after the usual configuration steps for add a new Qt version)

I get the same error doing a vanilla install on 10.6.8 . :

Error during installation process (qt.521.clang_64.essentials):
Command install_name_tool failed.
Arguments: -id /Users/jdp/Qt5.2.1/5.2.1/clang_64/lib/QtHelp.framework/Versions/5/QtHelp /Users/jdp/Qt5.2.1/5.2.1/clang_64/lib/QtHelp.framework/Versions/5/QtHelp
Output:

This happens twice. I ignore it and the app installs.

There are no example projects available from the GUI.

I am able to create a new project. Whenever I do anything, I get:

:-1: error: The Qt version is invalid: Qt version is not properly installed, please run make install

This is not a very helpful message. I did not download the source.

Hey guys, this really should work out of the box. If this version does not work for 10.6.8, you should state that somewhere; usually there is a system requirements link. I couldn't find one on your site.

For the record, Lion and Mountain Lion don't support multiple monitors very well and I'm not ready for Mavericks.

Please explain how to get this working.

Update your Xcode to 4.2 (it's free) it works on Snow Leopard 10.6.8.
I think Xcode 3.2.6 prefers gcc compiler, but Qt prefers clang.
Xcode 4.2 has a much better clang support.

jimphillips

Thanks for the quick reply.

I am using Xcode 4.2. Why does this matter? Is Qt using Xcode somehow?

What about the "install_name_tool failed" message? Isn't that a bug in the Qt installer? Could that explain the "Qt version is invalid" problem? Or are these two separate problems?

hskoglund

Aha, sorry I thought you were still using Xcode 3.2.6 (1761).
Also check that you have installed the command line tools for Xcode.

jimphillips

I think I did a full install of Xcode. How do I check for command line tools?

hskoglund

Easiest might be just to install them anyway:
Inside Xcode, Preferences Downloads, look in "more downloads", log in to Apple and choose "Command line tools for Xcode".

Also start a Terminal and type install_name_tool to see that it starts ok.

jimphillips

I don't see command line tools for Xcode under preferences: downloads tab.
install_name_tool appears to be there. I get the following in the Terminal:

MacMini:~ jdp$ install_name_tool
Usage: install_name_tool [-change old new] ... [-rpath old new] ... [-add_rpath new] ... [-delete_rpath old] ... [-id name] input

hskoglund

install_name_tool ok, good.
About command line tools for Xcode 4.2, it seems there is no separate package for it, sorry! They're supposed to be installed together with Xcode, and should be installed at /Developer/usr/bin or /usr/bin.

jimphillips

They appear to be at /Developer/usr/bin.

What does this have to do with Qt?
