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? |

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, Mike G. |

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

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. Mike G. |

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

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: http://www.gossamer-threads.com/archive ... al_P87071/ Thanks, Mike G. |
