Hi all,
Thanks for your responses. Atte, I wasn't aware that there was a python
version of the application, or that it would be relatively easy to set up -
I did get that working, so thanks for the tipoff.
Robin - thanks also. With your suggestion I did get paulstretch to compile
correctly. I had tried running ./compile_linux_fftw_jack.sh earlier, but
hadn't twigged that deleting PAaudiooutput.cpp would fix the problem.
Thanks again! Now I'm off to do some extreme timestretching.

Hi all,
I recently tried compiling paulstretch on ubuntu 11.04, and found that it
ran into some problems compiling. Here's the output from running
compile_linux_fftw.sh:
PAaudiooutput.cpp:29:9: error: ‘PaStreamCallbackTimeInfo’ does not name a
type
PAaudiooutput.cpp:29:35: error: ISO C++ forbids declaration of ‘outTime’

PAaudiooutput.cpp:29:43: error: ‘PaStreamCallbackFlags’ has not been

PAaudiooutput.cpp: In function ‘void PAaudiooutputinit(Player*, int)’:
PAaudiooutput.cpp:40:94: error: invalid conversion from ‘int (*)(const

PAaudiooutput.cpp:40:94: error: too few arguments to function ‘PaError

long unsigned int, long unsigned int, int (*)(void*, void*, long unsigned
int, PaTimestamp, void*), void*)’
/usr/include/portaudio.h:355:9: note: declared here
I did some googling, and it seems that paulstretch is written to use, and
depends on, portaudio version 1.9 (package portaudio19-dev on ubuntu).
However, this conflicts with the more recent version of portaudio, which
Jack (and all my Jack apps) seem to depend on. Does anyone know of a way
around this?
Compile it with JACK and without portaudio support:
./compile_linux_fftw_jack.sh
Note: the build-script compiles *.cpp - yet no function from
PAaudiooutput.cpp is used in the JACK version. Either fix the
build-script or simply mv PAaudiooutput.cpp PAaudiooutput.outoftheway
Failing that, does anyone know what the
likelihood is of
paulstretch being patched to use the newer version of portaudio? (Is
development on it still active?)
AFAIK Paul Nasca does still develop and maintain it.
Thanks for your help,
James
