Okay, tried out locating libbabo.so and it just plain doesn't exist on my
machine.

Thanks for the tips everyone.

.so is dynamic (shared object), .a is static (archive).

-Ldir says to the linker, look for .so's and .a's in dir. So /usr/lib was
scanned (as it almost always should be, along with /lib and /usr/local/lib).

You can proceed by putting the dir where libbabo.so is as an -L option in
custom.py. If libbabo.so isn't built yet when it's being linked with, then
that's a bug in SConstruct I need to know about.

Thanks for the tips everyone, I'm keep track of them all so we can do an
idiot's
guide to compiling by the end of this. ; )

Ok, libasound is located:
/usr/lib/libasound.so.2.0.0
/usr/lib/libasound.so.2
/usr/lib/libasound.so
/usr/lib/libasound.la
/usr/lib/libasound.so.1

My errors said:
gcc -static -o cscore util1/cscore/cscore_main.o -L. -L. -L. -L/usr/lib
-L/usr/local/lib -L/usr/local/lib -L/usr/X11R6/lib -lcsound -lsndfile -lfltk
-lpthread -lm -lXext -lX11 -lsupc++ -lportaudio -lasound -lfltk -lstdc++
-lpthread -lm -ldl
/usr/lib/gcc-lib/i386-pc-linux-gnu/3.3.2/../../../../i386-pc-linux-gnu/bin/l
d:
cannot find -lasound

I assume the above means it looked in /usr/lib? However, I don't know how to
tell if this is dynamic or static, or whether it is in the right place. Do I
just look at the compiler output and see what dir is being searched?

Next, if I use makeDynamic=1:

gcc -o hetro anal/adsyn/het_main.o -L. -L. -L. -L/usr/lib -L/usr/local/lib
-lustub -lsndfile -lstdc++ -lpthread -lm -ldl
gcc " -shared" -o libbabo.so Opcodes/babo.os -L. -L. -L. -L/usr/lib
-L/usr/local/lib
gcc:  -shared: No such file or directory
scons: *** [libbabo.so] Error 1
scons: building terminated because of errors.

I think I got further, but I have no clue what the above means.

As to how to install stuff, so far I've noticed that Gentoo's emerge method
puts
everything in the right places, but could this vary package by package? It
would
be nice to keep track of that element too, as I must say Gentoo was an
absolute
breeze to get alsa audio and midi working, as well as patched kernels.

Thanks
Iain

of course it does not!  The error is in the line to create it

The problem is that the line should be
gcc -shared -o libbabo.so Opcodes/babo.os -L. -L. -L. -L/usr/lib 
-L/usr/local/lib

note the lack of " which mean that you have an argument beginning with a 
space which is being treated as a file name to link or compile, and you do 
not have a file -shared

What I see is

xenakis:~/Sourceforge/csound5> mv libbabo.so xxx.so
xenakis:~/Sourceforge/csound5> scons makeDynamic=1

Note that there is no " -shared"
I did an cvs update late last night do this is with latest versions

For example, what does your custom.py say?
What version of scons?

i had the same problem, but upgrading to scons 0.95 seems to have fixed 
it (and allowed everything to compile,  albeit without csoundvst!!)

note:  to successfully compile with portaudio and jack enabled i needed 
to add jack to custom.py, as per the following:

    customLIBS.append('jack')

so, to recapitulate, csound5 seems to compile with the following

- redhat 9.0
- gcc 3.2.2
- portaudio v.19
- scons 0.95
- python 2.2.2
- libsndfile 1.0.5
- alsa 0.98

- makeDynamic=1 (maybe this should be set to '1' by default if 
platform=='linux'?)
- buildCsoundVST=0
- adding 'jack' to custom.py (for portaudio/jack support-- currently 
doesn't work)

I'd love to try this at home, but I'm just short of time. Could someone
write down a fool-proof, step by step instructions: what to get, what to
configure, what to fix, what to compile, in what order, what to do in
that case and in that eventuality...:)

Linux, Windows...

Hi Glyn and all,

You can also use the useJack=1 commandline flag I put in a while ago. 
It does the same thing and was added for this exact reason of if
portaudio was compiled with jack.
