Subject: [CSOUND-DEV:4610] Csound 5 compile on gentoo


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)
frontends/CsoundVST/CsoundVST.cpp:247: error: (Each undeclared identifier is
   reported only once for each function it appears in.)

   (first use this function)
frontends/CsoundVST/CsoundVST.cpp:273: error: `PyLong_AsLong' 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'
gcc -static -o cscore util1/cscore/cscore_main.o -L. -L. -L. -L/usr/lib

d:

collect2: ld returned 1 exit status
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:

ranlib libcsound.a

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

Thanks. However, locate ( I did do updatedb ) doesn't find a python.h. Is this a
file that comes with python, or is this something that should have come from
csound5 cvs? I didn't install python 'cause it was already on my gentoo install.

Hi Iain,

I'm not sure how python installs on gentoo, but I know Redhat systems
usually separate binary packages and dev packages.  It might be the case
that when installing on gentoo you may only installed what was necessary
to use python but not the dev libs/headers needed to compile programs to
link with python.

Thanks Steven. I downloaded the sources from python.org and installed manually.
However, still I can find no file called python.h. I found python.c and
python.o, but not .h. Any clue where this file should be or why I don't have it?
I just downloaded the sources, did ./configure, make, make install. Didn't
specify anything to configure.

By the way ( stupid linux newbie question ), where is it customary in linux to
install dev tools anyway? /usr? 
 
Thanks
Iain
