Hi people,
I have a problem running the lua_FFI Example. I am running OS X Catalina and I am using the code provided here. In order to get past the error message that luajit couldn't find the csound64 library I add libcsnd6.6.0.dylib to "local csoundApi = ffi.load('libcsnd6.6.0.dylib').
After this step the example completes fine, but without any sound coming form Csound.
The score gets compiled and everything but Csound doesn't output sound, it seems to shutdown after like 1 second.
attached is the output of the console after I run following command.
I don't know what I am doing wrong.
Best,
luajit Untitled-1.lua

This script requires either LuaJIT from luajit.org, or regular Lua with the
luaffi module. The script demonstrates how to generate a Csound score in Lua,
and then realize the score using Csound 6 via the Csound API accessed through
the foreign function interface (FFI).
The code prints comments to explain every step.
Local variables should be used whenever possible with LuaJIT.

Hi people,
I have a problem running the lua_FFI Example. I am running OS X Catalina and I am using the code provided here. In order to get past the error message that luajit couldn't find the csound64 library I add libcsnd6.6.0.dylib to "
local csoundApi = ffi.load('libcsnd6.6.0.dylib').After this step the example completes fine, but without any sound coming form Csound.
The score gets compiled and everything but Csound doesn't output sound, it seems to shutdown after like 1 second.
attached is the output of the console after I run following command.
I don't know what I am doing wrong.
Best,
