Can I use Qt4-tcz's from Raspberry TCL 7.0 in 8.X somehow?

[silvio]

Hello,
I would love the use something that needs Qt4, but if I looked right, until now there is no Qt4 support in the current 8.X repository. Can I use the tcz files of the previous release 7.0 of tiny core linux for Raspberry somehow? or will it not work because of some reasons?

The 7.0 release of tiny core linux didn't run on my Raspberry 3.

I don't know how to compile such a big project (Qt4). Is there a repository of the old tcz-build-projects somewhere, maybe I could use it and try to adapt it?

Thank you in advance.

Silvio

I copied all qt4-files from 7.X repo manually into the optional-folder of my 8.1.5 tc and made some really ugly and dirty adoptions (renamings) in the .dep files. Now I can run qmake and make and it fails at the beginning, because it cannot find some headers, but those files are at least somewhere . Does anyone have an idea?

I don't know if QT4 from 7.x will work on 8.x, but in theory you did the right thing.
However, you need to install  compiletc.tcz  in order to get the most needed stuff for compiling?

[bmarkus]

I did not try the 7.x on 8.x but it is expected to work. Qt4/Qt5 for 8.x is on the todo list but with low priority.

[silvio]

Thank you for all responses. The hint using the compiletc helped a lot. Now it goes through until linking process. I get some kind of this messages :

Code: [Select]

moc_mainwindow.o:(.rodata+0x244): undefined reference to `typeinfo for QMainWindow'

But I made a big step forward.
thanks a lot.

I have no idea and searched the internet for hours. Possible that the current compiler version and the version the libs are being made are to far away !? But currently I have no idea.. If anyone has an idea, please let me know.

Hi silvio
Did you install the  qt dev  extensions? It looks like the  qt headers  are not being found.

[silvio]

Hello Rich,
yes, I installed compilertc (gcc only doesn't work) and qt4-dev (and all the recursive tcz's automatically through this). qmake (part of qt4-dev) works without any problem and the compiler generates all object files (called via make), but the last step, linking to an executable file, fails. At the moment I didn't find a solution. If you have an other idea what I can try, I will be thankful. May be there is an additional option for the compiler, which I don't need for other distributions of Linux.

I found one very old post that indicates a compiler version conflict. Maybe I can try to use an other version of gcc/++ ?!
or a second point, the order of libraries.

Very interesting.. all this

What version of qt-4.x are you trying to compile?

Did you take a look at this:

http://tinycorelinux.net/6.x/x86/tcz/src/qt-4.x/compile_qt4

[curaga]

Looks like your app needs "-fno-rtti".

This looks very interesting. I should try this.

Looks like your app needs "-fno-rtti".

I have read this too, but I didn't need it on other distributions of Linux. But I will check this too.

Thank you very much, I'll give feedback

[bmarkus]

Just let you know, I bult Qt 5.8.0 for piCore 8.x I will pack it to .tcz in next days

[silvio]

I added

QMAKE_CXXFLAGS += -fno-rtti

in the qt project file and it works for me. It compiles and links as it should do and the application seems to run without any issue.

Thank you for all your help!!

Qt5 sounds interesting , by the way
