[mythtv-users] Undefined symbol error when running CVS

[Jason]

Woa...I didn't expect to start a flamewar!

I did remove any of the myth components after I did apt-get uninstall 
mythtv and got a fresh copy of the CVS and began compiling. I wanted to 
make sure that everything went smoothly, so I compiled all the libs one 
at a time. making both libs/libavcodec, libs/libavformat completed 
without errors, but when compiling /libs/libmyth I got the following 
error:

/usr/bin/ld: cannot find -lmythsamplerate-0.16
collect2: ld returned 1 exit status
make: *** [libmyth-0.16.so.0.16.0] Error 1

I couldn't find anything in either the user or dev mailing lists that 
make any mention of mythsamplerate. I appreciate all of the help I am 
getting here.

Thanks,

Jason
