is it ok to say, tweak a bit of code and recompile? or is that not a good idea?

and if its ok, where is the source

Thanks
J

tweak to your heart's content...which souce are you looking for?

I guess I was assuming that the mythtv code and its modules was placed somewhere where it would be easy to make small changes and recompile it. Is there such a place or do i have to download the code?

oops i didn't see there was a directory called r4_src for the mythtv user

If I were to modify a local build I am assuming that I would need to grab the latest code from CVS, True or false?

Is CVS installed with teh knoppMyth disto?

Once I compile with my modifications how to I test my executables locally?

Keep in mind that I am a windows NT driver developer. This has been my first experience with unix in 6 years.

Thanks,

False. Only use CVS if you want some new feature that is in CVS.
No. That doesn't mean it cannot be done. That a look at the MythTV How-To.
make install. The installed MythTV packages were made with checkinstall, so you can just reinstall the .debs if you messed something up with your build.


You're welcome. Keep in mind that everything in MythTV is stock. The code has not in anyway been modified by Dale or I.

Ok,
I have decided that I would tweak mythmusic, so I unpacked mythmusic and compiled.
The next step is make install (I haven't done this yet). This process puts the libmythmusic.so file into the following directory: /usr/local/lib/mythtv/plugins.

I did a little searching and I also found *.so files related to myth in the following directory : /usr/lib and /usr/lib/mythtv/plugins. I am assuming that these directories are for the package that were initially installed.

Once I complete the make install I am assuming that the system will pick up my compiled version of mythmusic in usr/local/lib/mythtv/plugins. If I were to break my version of mythmusic I can go back to the original by deleting the *.so file in the /usr/local/lib/mythtv/plugins and the *.so will be used in the /usr/lib/mythtv/plugins directory. Correct?

I am a windows developer, Linux newbe and I am being cautious.

Thanks,
Mike G.

cd into the mythmusic sub-dir
make distclean
vi settings.pro
change /usr/local to /usr
Then follow the compilation instructions in the How-To.

cesman

cesman,
so by changing /usr/local to /usr the libmythtmusic.so will be put in the correct directory for execution. When you refer to the HOW-TO are you referring to the README that is located with mythmusic or the how-to document on mythtv.org?

Thanks for your patience.

I am trying to recompile mythtv because the frontend freeze issue has been found.

Thanks
Mike G.

I get the following error:

Odd as I had no issues compiling 0.12 at all. Perhaps remove 0.12 and compiling 0.13 from source?

Oh I forgot to mention that I recompilied the kernel to 2.4.22, would that make a difference?

When you say remove r12 do you mean dpkg -r myth<tab> until all are gone as stated in a previous post?

Thanks for your help.
I am looking forward to fixing this front end freeze.

Mike G.

This is what I did to compile r12.
untared source

$export QTDIR=/usr/share/qt
$export PATH=$PATH:$QTDIR/bin

./configure
qmake mythtv.pro
make

I don't think installing 2.4.22 would have a difference. Yes, dpkg -r myth<tab>. Steps you took look good.

The compile of 2.4.22 was the result of the compile error in mythtv. Bad interaction with the kernel headers.
See following link:

I successfully compilied and installed 0.12 mythtv that was packaged with the distro. Unfortunatly my remote no longer works.

Any suggestions.

Thanks,
