Just a quick report. I built and installed Cs5 from the source tarball
yesterday with this support:
I ran scons at its defaults, adding only buildCsoundVST=1. Compilation
was fast, and the binary performs as advertised. No stress tests yet,
but I checked out some realtime I/O, it seems to be working all right.
Btw, all necessary devel packages were available from the Debian
repository, including boost and SWIG. Nice.
As always, vast thanks to all the Csound developers !
