Is [oggcast~] the object to live stream audio to another computer? And which one is the receiver? It's not mentioned in the help patch.

oggcast~ is the object to feed a streaming server, like icecast. it's main purpose is to build a web broadcast, rather than a peer-to-peer communication. (you will need a streaming server and a receiver, e.g. [oggamp~]; latency is usually quite high in such setups, expect >10sec)
for low-latency peer-to-peer streaming, check [netsend~]/[netreceive~].
if you are on linux (or osx), you could also use an external application
like jacktrip (aptitude install jacktrip) and use jack to setup your
routing between Pd, network and speakers.
finally, there's the iemrtp [1], which allows you to build an RTP streamer (both sides) within Pd.

Do I have to make the objects? There's no pd_darwin (I'm on os x) in the directory.. I did type make in this directory (I moved it to the 'extra' directory) and got this: cc -I"/Applications/Pd-extended.app/Contents/Resources/include/pd" -DPD -DVERSION='"0"' -arch i386 -arch x86_64 -mmacosx-version-min=10.5 -fPIC -I/sw/include -Wall -W -g -ftree-vectorize -ftree-vectorizer-verbose=2 -fast -o "unpackRTP.o" -c "unpackRTP.c" clang: warning: argument unused during compilation: '-ftree-vectorize' clang: warning: argument unused during compilation: '-ftree-vectorizer-verbose=2' clang: warning: argument unused during compilation: '-fast' In file included from unpackRTP.c:23: ./iemrtp.h:35:2: error: No byte order defined #error No byte order defined ^ 1 error generated. make: *** [unpackRTP.o] Error 1
Any suggestions?

Forgot to ask, are these the [netsend~]/[netreceive~] objects http://www.nullmedium.de/dev/netsend~/? Taken from this website: "If you're looking for objects to stream audio over the Internet this is not what you want! However, streaming over Internet2 or local 10Mbit or even wireless networks works very well." Internet2? It also is alpha and can't make that either. Tried different solutions with the makefile, like change pd_darwin to d_fat (took this from Lyon's book) and some other stuff, but nothing worked out. There's still much to learn about unix..

I'm actually trying to solve the make problem with the iemrtp library. The error I get when I type make in the library's directory is this: ./iemrtp.h:35:2: error: No byte order defined
I looked at the iemrtp.h file and what I understood is that I need the endian.h file, which I don't have. There is also an #if defined(__linux__) || defined(__CYGWIN__) || defined(__GNU__) || defined(ANDROID) which I commented out and left only the #include endian.h (bad, good? I'm on os x, so should I define something when attempting to make the library?).
I googled and found an endian.h file, copied it to the library's directory, but if I type make I get this error: ./iemrtp.h:26:10: fatal error: 'endian.h' file not found.
Can anyone help me out with this?

the thing is, that these objects allow you to create an RTP streaming solution - if you know what you are doing (you should have a good idea about what RTP/RTCP is; the objects will do the data-formatting/packaging for you, but you have to implement buffering, resampling, packet-loss correction,... yourself and within Pd! currently the only supported payload is 16bit uncompressed audio.
these objects are not for the fain-hearted...
[netsend~]/[netreceive~] are definitely easier to use.

Ok, I don't know stuff about RTP/RTCP. So, I'd rather go for [netsend~]/[netreceive~]. In the README file though it says this: To compile for Pd, cd into the directory, where you found this README and type "make pd_linux", "make pd_darwin", "make pd_irix6" (make is supposed to be gnu-make) or "nmake pd_nt" depending on the operating system you are using.
But typing make pd_darwin I get this error: make: Nothing to be done for `pd_darwin'. Plus, on the website of these objects it says that they are currently unsupported...
The directory though includes .pd_darwin files, but trying to import the library in a patch, the console shows this: /Applications/Pd-extended.app/Contents/Resources/Scripts/../extra/netsend~/netsend~.pd_darwin: dlopen(/Applications/Pd-extended.app/Contents/Resources/Scripts/../extra/netsend~/netsend~.pd_darwin, 10): no suitable image found. Did find:
/Applications/Pd-extended.app/Contents/Resources/Scripts/../extra/netsend~/netsend~.pd_darwin: mach-o, but wrong architecture [import]: can't load library in 'netsend~'
Any tip on solving this problem?

this means that upstream already built a .pd_darwin for you.
Plus, on the website of these objects it says that they are currently unsupported...
this means, that it's author doesn't have time to answer questions. it doesn't mean that the objects don't work.
The directory though includes .pd_darwin files, but trying to import the library in a patch, the console shows this: /Applications/Pd-extended.app/Contents/Resources/Scripts/../extra/netsend~/netsend~.pd_darwin: dlopen(/Applications/Pd-extended.app/Contents/Resources/Scripts/../extra/netsend~/netsend~.pd_darwin, 10): no suitable image found. Did find:
/Applications/Pd-extended.app/Contents/Resources/Scripts/../extra/netsend~/netsend~.pd_darwin: mach-o, but wrong architecture [import]: can't load library in 'netsend~'
the pd_darwin that comes with the download is apparently for the wrong architecture (powerpc): you have to recompile.
$ make clean $ make
(alternatively simply delete all .pd_darwin files (and probably .o files) before running "make"):
