still building QT! Its taking ages!!!!!

Edit: Ok finally I've managed to get it working! nice way to spend a friday at work

but....
I'm getting this problem

QSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: available drivers:
QSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: available drivers:
QSqlQuery::exec: database not open

any ideas??? I think its got something to do with sqlite package.

Further edit: ok SQLite did not install ok. just got back to Leicester, will fiddle with this for a bit see if I can resolve. Just seen Cybers post!

GREAT!

got it working

I had to copy your libqsqlite.so file to

/usr/lib/qt/3/plugins/sqldrivers

from 1st impressions im happy with it!

Daedalus_Z and M11VNY,

I'm glad you got headunit compiled and working. There are a few bugs with playback that shouldn't be too hard to fix. If you do end up making changes to the code, please send me your changes so I can incorporate them into CVS. If you end up making a lot of changes, then I can give you access to the repository so you can check in your changes directly.

Sorry about the poor internal documentation... I'll try to add some more comments when I get a chance...

Daedalus_Z · 02-13-2005, 09:27 PM

hehehe ok, Dont worry about the lack of comments / doco, the sign of a true coder if the complete lack of anything that helps other's understand his code

Hi im new to linux and not sure how to compile headunit.
How do i include the stuff in the configure script, do i need to do that before i compile QT, etc

Im using Gentoo and used emerge to install QT, etc. IS that ok?

NoPistonPC · 02-25-2005, 11:14 AM

Try this:

Code:

USE="sqlite" emerge qt
USE="sdl" emerge xine-lib
emerge sqlite
emerge id3lib
tar zxvf headunit-0.3-src.tar.gz
cd headunit-0.3
qmake
make

If that doesn't work, you may have to manually compile the qt source yourself. To do that, just untar the qt sources into a temporary directory (if you emerged qt before then you should already have the source file at /usr/portage/distfiles/qt-3.3.xxx.tar.gz). Go into the temp directory then run the "./configure ..." command with the options specified in the headunit INSTALL.unix file. Then run "make". That should install qt properly. Then try making headunit again: "qmake", followed by "make"

Hello, I've tried to compile Headunit on a FC2 machine but I'm stuck with this problem:

And so on.
I've got absolutely no clue, what the problem is
I had id3lib installed but it apparently wasn't the right one, because I had the same error messages like someone already reported in the thread. Then I installed a self-compiled version and now I get those error messages.

Anyone some ideas?

I'm really glad, that there's a Linux version of MediaCar, because a friend of mine build a CarPC in his car, but he runs Windows and MediaCar and that's an absolut NONO for me, also at home

So

NoPistonPC · 03-28-2005, 02:05 AM

can you tell me the exact commands you typed to build headunit?

also, can you translate this to english:

"In Datei, eingefügt von XineMediaPlayer.cpp:12:
qxinewidget.h:60:18: xine.h: Datei oder Verzeichnis nicht gefunden"

P.S. In case some of you are wondering, there haven't been any recent updates to the code.

All I have time for these days is to provide a bit of support for people trying to get headunit running. Maybe this summer I will have more time...

Scyx · 03-28-2005, 03:49 AM

I just used, as said in the "INSTALL" file, "qmake" and after that "make".
It sais: "Inserted in file of XineMediaPlayer.cpp:12
qxinewidget.h:60:18: xine.h: File or directory not found"
Here's the last 3 to 4 lines before the prompt in the shell:

Code:

qxinewidget.h:236: Warnung: `void DestSizeCallback(void*, int, int, double,
   int*, int*, double*)' declared `static' but never defined
qxinewidget.h:240: Warnung: `void FrameOutputCallback(void*, int, int, double,
   int*, int*, int*, int*, double*, int*, int*)' declared `static' but never
   defined
qxinewidget.h:242: Warnung: `void XineEventListener(...)' declared `static' but
   never defined
make: *** [XineMediaPlayer.o] Error/Failure 1

I translated the "Error/Failure" output directly, but I don't know what would be the exact word there in english.

Actually I didn't wonder because I didn't notice, but I absolutely understand it, when your too busy from college to continue what you would like to continue

The support is already a big help in cases like this with numerous of crazy warnings or errorrs

rickcorp · 03-28-2005, 07:35 AM

Any new releases scheduled for this, I am very interested in this as, I believe a linux option at this point seems to me a better way to proceed?

Thanks, and great work so far.
Rick

NoPistonPC · 03-29-2005, 12:54 AM

Scyx, I think the problem is that xine isn't installed properly. If you have installed the xine package in fedora, make sure that it also installs the headers and libraries. I haven't used fedora in a while so I can't remember if there is a separate xine development package. If there is, you may have to install that. Otherwise, you can always download the source from the URL specified in the INSTALL file and compile it yourself (./configure --enable-sdl && make && make install).

In any case, that's the reason you're getting the errors.

While you're at it, make sure you also have all the other libraries installed that are listed in the INSTALL file.

rick, no new releases are scheduled at this point, but like I said before, I may have time this summer. Regarding using linux as the basis for a CarPC, I think it is a great alternative to Windows. If we can put together a complete CarPC distribution, many more people will be able to use it...even those that don't know anything about Linux. Also, despite what others have said (who probably haven't tried recent versions of Wine), most of the popular Windows-based GPS software, like Destinator and iGuidance, run perfectly fine using Wine.

But, having said all this, it does take a lot more effort to get something up and running in linux (as you can see from the posts in this thread). But, I see the CarPC is a hobby, and building the software is as much fun for me as the hardware. Now, if only I had more time... Maybe if I did a little less of this:

...i would.

Scyx · 03-29-2005, 03:43 AM

Alrighty

Now, the compilaton works fine

Apperantly the FC packages of xine-lib weren't build with explicit SDL support.
But there's no another problem... I can start headunit, then select the directory where to search for music, it also syncs the database, but when I then want to start the UI, all I get is lots of these errors:

Code:

QSqlQuery::prepare: database not open
QSqlQuery::exec: database not open

and just before the prompt:

Code:

Segmentation fault

@NoPistonPC: Any idea, what this could be? As I know my luck, probably incompatibilty with FC

[edit] I should better read carefully the rest of the postings

I'm now trying the solutions that are there mentionned about loading the SQL driver

[edit2] I already compiled QT on my own yesterday, but, to not mess up with the installled QT it wanted to make a RPM using checkinstall, worked good. But as I wanted to install, it didn't work.
So my question now, how can I load manually this SQL driver? All the necessary files should be in the directory where I configured and "maked" QT, or am I wrong?

I actually did try iGuidance (2.0) under the latest WINE and it ran well except it crashed a lot. Do you have it running "perfectly", because I would honestly like to hear more. It is the only thing stopping me from running Linux and quite frankly it sucks. Were there some tweaks you made?

Let us know.

Allan_MA70 · 04-11-2005, 06:54 AM

anyone tryed this under xbox linux?

Let us know.

Can you post the app defaults you used? I don't have mine anymore, but I can probably start with yours and figure out which native DLLs to use... also, sometimes, older windows DLLs work better... If we do put together a distro, all these details can be hidden from the end user.
