You must use v19-devel for PortAudio with Csound 5.

Subject: [Csnd] Problems compiling Csound5 with PortAudio on ubuntu

I'm running ubuntu Hoary. Tonight I downloaded the current CVS and 
attempted to compile. On my first try, I did not have PortAudio 
installed. Csound5 compiled fine and ran fine too...but the ALSA module 
apparently doesn't support full-duplex. I am assuming that the PortAudio 
module *will* support full-duplex, so I decided to install portaudio on 
my system and try to compile again.

I followed the directions for building PortAudio from the source (i.e. 
did *not* use the Debian binaries) using the directions here:
http://lug.wsu.edu/node/285
As this went without a hitch, I assume I successfully installed 
PortAudio V18.1.

I then returned to the csound5 source directory and typed:
scons -c
and then:
scons
this time scons reported that it found portaudio.h. It also reported 
that it would build the portaudio module. However, the compile process 
is now broken. The first error is:
InOut/rtpa.c:33: error: syntax error before "PaHostApiTypeId"

Which is apparently a result of this following command:
gcc -Wall -g -gstabs -O2 -DLINUX -DPIPES -DHAVE_FCNTL_H -DHAVE_UNISTD_H 
-DHAVE_STDINT_H -DHAVE_SYS_TIME_H -DHAVE_SYS_TYPES_H -DHAVE_TERMIOS_H 
-DHAVE_DIRENT_H -fPIC -DBETA -I. -IH -I/usr/local/include/python2.3 
-I/usr/local/include -I/usr/include -I/usr/X11R6/include -c -o 
InOut/rtpa.os InOut/rtpa.c

If I remove PortAudio, the compile process again works...and I have no 
PortAudio module.

I now have tried compiling with V19 of PortAudio. Now it compiles. 
However, when I try to run Csound5 I get

WARNING: could not open library
'/home/john/Desktop/SoundScratch/stuff/csound5/librtpa.so' (-1)
...
*** error: unknown rtaudio module: 'PortAudio'
Failed to initialise real time audio output

and... in the directory mentioned, librtpa.so is indeed there.
Permissions are set to 777

I also tried using ALSA for DAC output. I consistently get this error 
message:
ALSA: -B 8192 not allowed on this device; use 15052 instead

(the number after -B varies depending on what I try in the command line. 
For example, I tried its suggested -B 15052 in the command line and then 
I get that -B 16384 isn't allowed.)

So...how do I find the magic number for -B? And...do I want to be 
choosing the default dac?

BTW, is it possible to add code to Csound5 so scons checks for the
correct version of PortAudio?

-John

Sounds like you have not set OPCODEDIR

Try adding -b 7526 (or maybe -b 3763) as well in addition to -B 15052,
so that -B/-b is an integer. Also, if you use the default device with a
newer version of ALSA, it is probably the dmix device; I recommend using
a hardware device directly such as -o dac:hw:0,0 (change the numbers to
select card), not only for making choices of buffer size less limited,
but also for improved latency.
