Wow, this is a LOT more fun on linux, especially gentoo. I'm following all the
instructions in the pdf file. I emerged boost, fltk ( configured with
-enable-threads ), libsndfile, portaudio 19 ( from cvs snapshot ), SWIG, and
scons. Checked out the csound5 sources from cvs. Because I don't know where to
put things, I did all this as root and installed everything in my / dir. ( If
this is wrong could someone tell me? ) All the above was dead easy compared to
cigwin or mingw.

On to Csound5. Using the default scons, which wants to build CsoundVST as well,
I hang on the following:

frontends/CsoundVST/CsoundVST.cpp:247: error: `PySys_SetArgv' undeclared (first
   use this function)

scons: *** [frontends/CsoundVST/CsoundVST.os] Error 1
scons: building terminated because of errors.


Changin Scons to not try to build CsoundVST, I get further ( I think ) and hang
on the section where a whole slew of tags appear, specifically here:

frontends/CsoundVST/Silence.hpp frontends/CsoundVST/StrangeAttractor.hpp
frontends/CsoundVST/System.hpp
sh: line 1: etags: command not found
scons: *** [TAGS] Error 127
scons: building terminated because of errors.

Changing Scons again to not generate tags, I get the below:

util1/cscore/cscore_main.c: In function `main':
util1/cscore/cscore_main.c:28: warning: implicit declaration of function `lcount'

scons: *** [cscore] Error 1
scons: building terminated because of errors.

Does the above mean that my alsa stuff is not being found? And if so, any hints
on how to solve this? I know very little about linking and paths on linux.
And lastly, changing SConstruct to not use PortAudio ( I assume that's what
wants to find asound ), I get:

Hope that helps track down something or another, or at least sheds some light on
what further instructions might be good to have in the how to file.

Thanks
