I've been fiddling with the Mepis installation code and generated a new 'minstall' binary. It compiles and runs fine on my desktop (Mepis 11 a4).

However, when I try and run it in a Vbox session instead of the one in /usr/sbin/, but I get this error:


If I run 'file' on the two files I get different output:


So, they're not identical. Is that the cause? Does anyone know what I need to change in my environment to get it working?

Sounds to me as if you have different library versions. Some Qt & KDE libs are not compatible across versions. If you compiled with ver. 4.7 Qt libs you can't run with 4.6 Qt Libs. The M11a4 CD comes with Qt versions 4.6.3 but IIRC, Warren just updated Qt to 4.7 in his M11 repos.
So either downgrade your Qt libs or wait for M11a5 which will have the new Qt on the CD

For GNU/Linux 2.6.8? Do you use another kernel? In any case I bet Tim is right it's a matter of library.

That's true. I did do an update in synaptic... How do I downgrade? Sounds like it could be a pain. It may be just easier to reinstall aplah4.

The 4.6.3 Qt libs are still in squeeze, so it's possible. It would probably be easier with aptitude. Just choose a lib you don't have installed, like libqt4-dev, disable Warren's repo, reload, then install that lib with aptitude. It's preferred solution should be to downgrade all the Qt libs to the squeeze version.

You also may look into doing a proper .deb package of it. Most qt4 apps can now just use debhelper to handle the packaging, so you would just use the "tiny" rules file (which dh_make in Squeeze seems to hand me by default)

Then, during the packaging, dpkg-shlibs extracts the minimum library requirements from the finished binary and adds it to the control file in the deb package.That way the QT 4 version problem would have been obvious when you tried to install it in the virtual machine.

Thanks Stevo. However, the vbox session is a liveDVD session so I can't install anything. I'm trying to replicate a real installation.

You can use the aufs cheatcode even in VB. So installing is possible.

I didn't think that was enabled in the mepis11 alphas yet?

OK. I couldn't get the downgrade to work in Synaptic nor could I get my head around aptitude. A quick re-install later, I was back at a virgin Mepis 11 a4 install...

Without doing the updates to Qt 4.7 the binary still compiles fine and now works flawlessly in a liveDVD session

I'll post it in a new thread.
