Install instructions for Zyn-fusion

[Deanodirector]

Hi, I installed Zyn-fusion by cloning the mruby-zest-build git, copying those files into the folder with the demo install files and running install-linux.sh. The interface starts but it crashes when I try to save instruments.

I was just wondering if I installed it in the correct way or if there were instructions somewhere on the proper way to install.

Many thanks

It doesn't sound like you've actually compiled the code in mruby-zest-build. You'd want to compile the code there to obtain a new version of the interface (i.e. a new libzest.so). This can be done via "make setup && make builddep && make" followed by an optional "make run" for testing. Moving the libzest.so directly to /opt/zyn-fusion/libzest.so should be enough to update your version.

If you want more of the full packaging details you may also want to see https://github.com/zynaddsubfx/zyn-fusion-build .

thanks for the response. make setup and make builddep run fine but make given the following error

Code: Select all

ruby ./rebuild-fcache.rb
./rebuild-fcache.rb:2:in `require_relative': cannot load such file -- /home/ollie/zyngit/mruby-zest-build/src/mruby-qml-parse/mrblib/main.rb (LoadError)
	from ./rebuild-fcache.rb:2:in `<main>'
make: *** [Makefile:7: all] Error 1

I tried the build script but it failed with the error:

Code: Select all

That looks like you don't have the git submodules checked out. This is done with "git submodule init" and "git submodule update"

[Deanodirector]

the git submodule commands did the trick! Then installing the demo and copying the new libzest worked too, thanks!

I guess I won't need the build scripts now but aside from the too many levels of symbolic links errors, I noticed in build-linux.rb lines 84 and 109 contain "chown mark". Is that supposed to be replaced with a particular user?

[Deanodirector]

nope, still has the demo timeout....

[fundamental]

The GUI should now have no demo timer, but to get rid of the core/secondary demo timer you need to recompile 'zynaddsubfx' itself. This is part of what the zyn-fusion-build scripts do. No idea what exactly is causing the symbolic link issue there though. As long as you update the git copy of zyn-fusion-build, the chown should be disabled.

[Deanodirector]

thanks for the response.

I deleted everything regarding Zyn, including a rogue symlink I found. The build process finished, with a few errors regarding invalid user mark. Zynaddsubfx starts but immediately stops with the error

zynaddsubfx: Failed to launch Zyn-Fusion: No such file or directory

I tried the build script in release mode only and with my username instead of mark and while it again build fine, Zyn would not start and gave the same error as above

[fundamental]

it doesn't sound like you updated the zyn-fusion-build repo with fixes which were done over the past day or so. Additionally it doesn't sound like you actually ended up installing the release tarball built by the scripts.

[Deanodirector]

Aha, I assumed the script would have installed everything. Installed the tarball and it works fine.

Thanks so much for your help
