Database Utility on a 64-bit Ubuntu System

[noiz77]

I just got a ipod video and have rockbox running on there and am very happy with the quality of rockbox, it is quite amazing.  I do want to be able to build the database using my computer though and I have read about the database utility.  I have gotten the source for rockbox and tried to compile the database utility and run into errors.  I am assuming that I need to get some libraries to make it all compile and was wondering if anyone knew which ones I would need to compile the database utility?  Or do I need to set up the whole development environment to be able to compile the database utility?

Actually posting the errors would help others give you advice.

Alright, this is the error that I get when I try and compile using the "make" command in the tools/database directory

Code: [Select]

Those errors sound like we have broken the compilation of that utility in svn and likely has nothing to do with your system.

The problem is that the database utility really has no fixed owner or maintainer. So it gets broken quite often, but no-one notices for ages.

Edit: And thanks to nls, it should now build again.

Ok, I fixed it

Awesome, I just compiled it this morning and it all checked out, I will have to test it tonight to make sure everything is working.  Thanks for helping me out.

Just got home and tried to run the binary that was compiled and it doesn't seem to be working.  The compiler didn't show any errors and there is no "--help" to know what the parameters are.  I assume that they are the same as the windows binary that I found posted on the forums but those parameters seem not to work.  When I try and run the binary there is no output and it looks as though nothing happens.  Are there parameters I am missing or do I need to reconfigure something?

The utility takes no parameters, it just scans for music and builds a database from the current dir so you should navigate to the root of the player and run it IIUC.

[noiz77]

Okay, that makes a lot more sense of how it works, no wonder it wasn't working for me.  I will have to move it to the root directory of the player and try it tonight.  Thanks for all the help, this will make rockbox even sweeter. 

Also, one other thing I thought about, does this update the database every time or does it create a new database every time it is run?  Just wondering since the windows binary had the option to do either one.

Man, so I have had this running and it worked beautifully the first couple times that I ran it, but now it is giving me problems.  It generates all the database_* files correctly, but then when I copy them to the .rockbox directory the new files show up in the database but they are not playable.  Anyone know why this is happening?  It seems to me that the player is not committing the new database when it starts up when using this utility.  Is there something else I need to do while using this besides just copying over the new database_* files?
