Compiling QT Error

[koenieee]

Hello,

I'm busy to create a development environment to create a plugin for my kobo.
But when the build script (kobolabs github) compiles QT there is a error:

/usr/bin/ld: skipping incompatible /home/koen/kobo/fs/lib/libdbus-1.so when searching for -ldbus-1
/usr/bin/ld: skipping incompatible /home/koen/kobo/fs/lib/libdbus-1.so when searching for -ldbus-1
/usr/bin/ld: cannot find -ldbus-1
collect2: ld returned 1 exit status
make[1]: *** [../../../bin/moc] Error 1
make[1]: Leaving directory `/home/koen/kobo/tmp/qt-everywhere-opensource-src-4.6.2/src/tools/moc'
make: *** [sub-moc-make_default-ordered] Error 2
Build failed at qt.sh, aborting

Something about ldbus-1.

Could someone help me?

Thanks!

I had the same error. try to install libdbus1-dev (if you're running any debian like linux)

[koenieee]

Ok thanks,

I tried this: sudo apt-get install libdbus-1*
but now it is asking for:

The QtDBus module cannot be enabled because libdbus-1 version 0.93 was not found.
Turn on verbose messaging (-v) to ./configure to see the final report.
If you believe this message is in error you may use the continue
switch (-continue) to ./configure to continue.
Build failed at qt.sh, aborting

I'm running on amd64 if that matters.

Great news, I did some things (no idea what) but it is compiling without any problems.
but it does take a very long time (more then 3 hours) is this normal?
I have another question:

Can I use QTcreator to create a app and let qmake compile it for the Kobo?

[KevinShort]

Could you look through your command history to maybe find out what it is
that you did to get QT to compile? When I tried to compile before I got stuck
at the error looking for libdbus-1 version 0.93, like you did.

[koenieee]

First do this:

set QT extra args to your prefered dir (QT_EXTRA_ARGS=--prefix=$HOME/kobo/qt),
then use this command: export PKG_CONFIG_PATH=/home/<USER_DIR>/kobo/fs/lib/pkgconfig <== make sure this path exists!!

test if you run this:
arm-linux-g++
you get no input files (not: command not found)
and then try it again.

Let me know if this was the solution!

P.S. I need to run build-all.sh as root because at the end 'make' needs access to a root dir. I don' t know if that is neccesary for you, but for me I needed to compile qt again (which took me about 3 hours )

[koenieee]

Could anyone try my first compiled QT program?
(the only thing it does it shows a button, when you click that it closes the app).

My Kobo isn't arrived yet but I'm just curious if all went well (compiling etc).

[KevinShort]

Thanks for the compile instructions, when I have time I'll give it a shot.

On my Glo, software version 2.1.5, your program returns "Segmentation fault".

[koenieee]

Thanks for trying,
but how did you installed it?

[KevinShort]

I just now realized that your program is a library file, not an executable.
How should I start it?

[koenieee]

Well I think you installed it like this:

*require ssh/telnet access
copy it to your kobo (/usr/local/Kobo dir)
restart your Kobo
open the book library
go back and in the menu you need to see my app.

Could anyone give better instructions because I think these are wrong/not complete.

Edit: I don't think it is working on firmware 2.x because I used QT version 4.6.2, and firmware 2.x is using QT 4.8

[KevinShort]

QT compile successful! Thanks for your help, koenieee.
And I think you're right about your program not working on the 2.x firmware.

[koenieee]

Shall I make a new thread how to compile QT 4.8 and setup QTcreator correctly?

[KevinShort]

I say yes, that would be very helpful.

By the way, I did not have to run build-all.sh as root. Maybe you
set some prefix to a directory that only root can write to?

[koenieee]

Well the first time I forget to set --prefix so QT used a default path (/usr/local/Trolltech) and needed access to a root dir.
