[RTcmix-discuss] A Fresh Build (errors)

[Blaine]

Now that I'm pulling down a fresh snapshot, I thought I'd throw out there
the errors that I'm having. Are these normal? I think originally I simply
ignored them and continued on, but for the sake of cleanliness these should
probably compile correctly without assistance.

64-bit ubuntu 10.04

When I configure and make RTCMIX, I get the following error when it builds
the example apps:
making in SYNC...
make[3]: Entering directory
`/home/blaine/src/rtcmix/RTcmix-all-092811/insts/bgg/SYNC'

make[3]: *** [libVWAVE.so] Error 1

When I go in there and add -fPIC manually and call the g++ call, I get a "ld
cannot find -lgen".

Am I doing something wrong? This is with the latest snapshot.

Thanks,
Blaine
