Sorry if this has been brought up before; I searched the Web and the
mailing list archives, but I couldn't find anything.

When I try to build Csound 5.07 with the Loris and STK opcodes,
unpacking first Csound5.07.0.tar.gz and then Loris_STK_src_5.07.zip
from the SourceForge download page for Csound, it fails to compile,
seemingly due to missing files in both the Loris and STK directories
that are presumably supposed to interface those external pieces of
code to the central bits of Csound.

The build looks something like this:

  $ scons usePortAudio=0 usePortMIDI=0 useALSA=1 useJack=1 \
          buildLoris=1 useOSC=1 useUDP=1 buildPythonOpcodes=1 \
          prefix=/opt/csound5 buildRelease=1 gcc4opt=k8 Word64=1 \
          Lib64=1 buildStkOpcodes=1 buildPDClass=1 install=1 \
          useCoreAudio=0 buildVirtual=1 buildInterfaces=1 \
          buildNewParser=1
  [pile of text omitted; full log attached]
  scons: *** Source `Opcodes/Loris/lorisgens5.C' not found, needed by target `Opcodes/Loris/lorisgens5.os'.  Stop.
  scons: building terminated because of errors.

When I look at the Csound 5.05 source, I see that the referenced file
exists.  Similarly, if I try to build without Loris but with STK, the
build halts while looking for the file Opcodes/stk/stkOpcodes.cpp,
which is also present in the 5.05 source tarball
(Csound5.05_src.tar.gz).  (I have not tried building 5.05 with STK and
Loris support yet.)

I don't see either of those files in either the Loris/STK secondary
source archive or the upstream versions of Loris or STK, so I assume
they're supposed to be part of the Csound source.  Are these supposed
to come from somewhere that I'm not recognizing?  Am I doing the build
wrong?  Or is it actually that the files are just missing from the
source archive, rendering the Loris/STK stuff uncompilable?  Is it
worth trying to copy those files from a 5.05 source tree?  I don't see
them in CVS either, according to the CVS browser.

Thanks for your attention.
