configuration fails due to something missing in PortAudio

[ariutti]

hi, I'm on Linux Ubuntu Studio 22.04 and I'm exeriencing some difficulties in trying to install CDP8. My steps are the following:

libaaio installation

1. entering folder CDP8/libaaio;
2. extracting archive libaaio-0.3.1.tar.bz2;
3. entering folder libaaio-0.3.1;
4. ./configure
5. sudo make install

portaudio configuration and build

I read the instructions in the file ‘CDP8/dev/externals/paprogs/palinuxbuild.txt’.

1. I reach the indicated website and download the pa_stable_v190700_20210406.tgz file;
2. placing archive inside CDP8/dev/externals/paprogs/ folder;
3. extract the archive in this position;
4. entering portaudio folder (which is not too clear from the instructions);
5. executing command ./configure --with-alsa --with-jack
6. executing make

building and installing CDP8

1. starting from folder CDP8;
2. create folder build with command mkdir build
3. entering folder with cd build
4. executing command cmake ..

I get this Output which makes me think there is some problem with PortAudio

the make command actually fails. Where am I going wrong? Thank you so much for your support

[empty0set]

I ran the CMake configuration step with '-DCMAKE_PREFIX_PATH' set to the path of libportaudio.a in paprogs/portaudio/lib/.libs/ to fix this.

[ryanthomas-org]

In my case, I had missed the original note in palinuxbuild.txt, and was a bit confused by the wording "one or two third-party libraries need to be built" in CDP8/building.txt and originally thought the included aaiolib might be enough.

I had the exact same error as OP on an Ubuntu 22.04 based distro.

I partially resolved this by running:

apt install portaudio19-dev

I was now able to run cmake .. without erors from CDP8/build, but make now failed as follows:

[ 99%] Building C object dev/externals/paprogs/paplay/CMakeFiles/paplay.dir/paplay.c.o
CDP8/dev/externals/paprogs/paplay/paplay.c:75:10: fatal error: pa_ringbuffer.h: No such file or directory
   75 | #include "pa_ringbuffer.h"
      |          ^~~~~~~~~~~~~~~~~
compilation terminated.
make[2]: *** [dev/externals/paprogs/paplay/CMakeFiles/paplay.dir/build.make:76: dev/externals/paprogs/paplay/CMakeFiles/paplay.dir/paplay.c.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:7671: dev/externals/paprogs/paplay/CMakeFiles/paplay.dir/all] Error 2
make: *** [Makefile:156: all] Error 2

I wasted a good amount of time trying to find a pa_ringbuffer.h file on my system thinking that portaudio19-dev might have provided it, but it did not.

Finally I grabbed the pa_stable_v190700_20210406.tgz file as OP reiterated, and saved the extracted portaudio folder at CDP8/dev/externals/paprogs/portaudio -- where I proceeded to follow the instructions in CDP8/dev/externals/paprogs/palinuxbuild.txt ( ./configure --with-alsa --with-jack ; make ) This is what actually built the missing pa_ringbuffer.h file

That was enough for the make file to find it and build it correctly at least in my case.

So, in summary, saving the portaudio folder downloaded from http://files.portaudio.com/download.html in place under my local copy of the CDP8 repository at CDP8/dev/externals/paprogs/portaudio, and building it there, was sufficient for CDP8 to build correctly

[yamzee]

Using a combination of the two above, I was finally able to get CDP8 to build correctly. I edited the CMakeCache.txt file to remove the PA-NOTFOUND, since no matter what I did it never found the portaudio libs.
