Makoto. Those Qt 4.80 packages have basic stuff compiled. They resemble the QT libs Barry Kauler made for Wary. The size is bigger because I cant compete with T2 compiling environment. Barry gets astonishing small packages with it.

Are they already possibly stripped, and maybe even further compressed with something like UPX? Smile

(Not that I know whether or not you could strip the Qt setup...)

They are stripped. UPXed no. And reboot is needed before they are recognized. The pinstall.sh is included in the main pet, at least.

Do Qt programs generally need the version of Qt they were compiled against, or higher?

I re-installed Qt 4.5.3, and installed your QComicbook 0.7.2 package... but if I try to run it, it always stops with this error:

Backwards compatibility is something I dont have right answer. Hmm...If I dont strip the compiled package, would it help, I dont know yet.

I am guilty. I confess my sins as using the latest Qt. I hope the penalty is not permaban.

I'm referring to developers of qt4 apps. If you browse qt-apps.org you'll find many apps which will not compile with qt4-4.3.2, but require newer releases of qt4.

Ok. Havent tracked much, since my used new Qt libs does not have that problem. But not all older apps do like the new Qt4 also. I get errors which seems to come from incompatibility when compiling.

As for backward compatibility...

I uninstalled QComicbook 0.7.2, and reinstalled the previous version I had (0.3.4, qcomicbook-v0.3.4-i486.pet), with Qt 4.5.3 still installed. Here's the error the 0.3.4 package throws with Qt 4.5.3 installed (as I mentioned in my first post in this thread):

Maybe, ttuuxxxx would know.

I take it you've already checked the storage tree at http://distro.ibiblio.org/pub/linux/distributions/puppylinux/.

Yes, and I went ahead and checked it again, just now... not every directory, though, of course. Embarassed

All I saw in the 4.3.1 directories was the Qt 4.3.2 pet. Smile

@makoto

apologies, I should have checked QT4 against the kernal version before answering.

According to the QT4 list puppy 4.3.1 's kernal should work with QT4.4.6/7, QT4.5 requires a later kernal.

Also:

your "qcomicbook: error while loading shared libraries: libqt-mt.so.3:..."

I haven't got this library on my dev box with QT4 either.

After a little chase,

I found it's a QT3 file, not a QT4 file (according to SLUG) and must be in a specific place. There are 48 listed errors against this one file and most seem to be still open (they go back to 2005). Part of Qt GUI Library (Threaded runtime version), Version 3.

Now I do know QT3 is in the tree and works in 4.3.1, as that's where I first used it (and I think Rolling Eyes

where ttuuxxxx Wink

first built a QT library for me).

It's probably worse since I'm using a Retro kernel (2.6.21.7, IIRC). Smile

(Even though I really shouldn't have been using it, for 4.3.1.)

Guess I should uninstall Qt4.3.5 and reinstall Qt 3.3.8, then. The version of QComicbook I have runs without problem, there. At the moment, it's the only Qt program on my system. Sad

(...and then I'll find something else I'll want to run that needs Qt4... Very Happy
