I have mythtv 0.18 running as a backend and also as a frontend on a system (both Mandriva 2006). I just bought a laptop, and would like to put it on there as well. However, the latest release is 0.19, and not compatible with 0.18 (I tested this, and got an error). The most logical thing to do would be to upgrade my backend to 0.19. However, it took me a lot of work to get it working, and I am a little hesitant to go this route. So, my next option was to get an older version of mythtv (0.18). I found that at the mythtv website.
I can unpack the zip/tar file, and run './configure'. I can also run 'qmake mythtv.pro'. However, when I run 'make', I get some errors:

make[2]: Entering directory `/home/eikeland/mythtv-0.18/libs/libavcodec'

make[1]: *** [sub-libavcodec] Error 2
make[1]: Leaving directory `/home/eikeland/mythtv-0.18/libs'
make: *** [sub-libs] Error 2

I don't really know what this means, but I have never been able to install mythtv from source (I did it from RPMs on the other machines). My system is 64bit, and I am not sure if this would make any difference when compiling.

So, my next step was to try and see if I could get an older version of the rpm (x64), but I have not had any success.
Does anyone know where I might be able to find an older version (0.18) of x64 mythtv (frontend)?
Or, even better, does anyone know why it won't compile?

Thanks

You should be able to obtain the older packages needed from their website or possibly other websites.

If you are unsure of their website then do a search at freshmeat.net and then you will be presented with a link regarding the proper website.
