Installation problems

[aha_1980]

Hi @Colins2,

please run ls -l /path/to/your/exe, file /path/to/your/exe and ldd /path/to/your/exe and print the output here.

How did you install Qt under Linux?

Regards

I installed Qt through the Debian package manager.

@Colins2 That looks all pretty good.

So if it does not run in Creator, there might be some environment variables screwed up.

If you have a recent Creator version, you can right click on a file in the project tree and choose "Open terminal with Run environment" and repeat the steps from above.

Okay, I opened the terminal right-clicking from within the IDE as you said. Here's the output:

The IDE is obviously finding the source files to compile but there is no way to select the debug or release directory from within the IDE.

As the source code is in ~/Qt_Programs/qtc14, is it normal for the compiled program to be in a completely separate directory, i.e. ~/Qt_Programs/build-qtc14-Linux-Release/qtc14?
I'd have expected it to be more like the Windows version and to have created build and release directories under the source directory, e.g.
~/Qt_Programs/qtc14/Build....... and ~/Qt_Programs/qtc14/Release?
I'm restricted to a 10 minute rule on posts at the moment.

.

[Colins2]

I just tried modifying the Build and Release directories as mentioned above to:
~/Qt_Programs/qtc14/Build/Release and
~/Qt_Programs/qtc14/Build/Debug

which to me, are more logical, but I got the same errors.
The files are built in the specified directory and both versions are executable from a terminal window.
Neither will run from the IDE but the error message does reflect the new paths.

I'm baffled!

What version of Debian are you using ?

[Colins2]

Hi,
Here are my system details:

[Colins2]

@aha_1980 @SGaist

More info:

I also have a Linux Mint 19.0 boot so I downloaded the installation direct from Qt.io for 64 bit Linux.
This installer ran and downloaded all the necessary tools.

I re-created the simple console app from above and it runs perfectly from the IDE (as you would expect)
Qt Creator is a different version to the one I have in Debian, maybe I'd be better off deleting the Debian installation and downloading direct from Qt.io.

[Colins2]

Solved!
Or, at least, problem overcome.
I just couldn't find anything wrong, nor any setting that would stop the program running so I deleted the whole Qt installation and then downloaded and ran the installer from Qt.io as I had with the Mint installation.
I am very pleased to say that everything works as expected now.

I still have no idea what the problem was except that it was an older version in the Debian repo and maybe it wasn't totally compatible with the latest distro?

I'll mark this as 'solved' even though the initial problem was not really solved. I guess the moral is to always get the software direct from the Qt site and not from a repo.
