Port to Csound 6.10

[quozl]

TamTam activities;

• use Csound 5.x via a C++ API shim,
• bundle Csound 5.x binaries; 32-bit only.

Reference: https://github.com/sugarlabs/tamtam/tree/master/common/Util/Clooper

Csound 5.x is not available on current Linux distributions.

A port to Csound 6.x using the Csound Python API (import csnd6) was done in the Music Keyboard activity. But the Csound Python API is deprecated.

A port to a more recent Csound such as 6.10 or 7.00 may use the ctcsound API provided in Csound 6.08 and later. See also https://github.com/godiard/music-keyboard-activity/issues/21.

I updated Clooper to use the csound_threaded.hpp api from 6.10. It seemed like an easier pivot than re-writing the looping logic.

Thanks, well done. On Ubuntu 19.04 x86_64, I've run python setup.py dev, then run make in common/Util/Clooper, then switched to the TamTamJam.activity and started it with sugar-activity. It makes appropriate sound from the default loops. I also tried TamTamMini.activity.

In both cases, some of the UI is broken; I guess the next step is to finish the port to GTK 3?

While trying to complete the port to GTK 3, activity fails to start with error;

And this seems to happen cos of this error; happens when I run make in common/Util/Clooper/

I have csound v6.12.2 installed.

If there's a need to replace the binaries, I haven't been able to find the latest ones if any.

You're missing Csound development files. On my system, the package name is libcsnd-dev, found by typing "sudo apt-file search csound.hpp". I don't know what the equivalent is on Fedora.

csound-devel on Fedora

Thanks, activity starts now.

Well done.
