Compiling ohSongcast

[simonc]

The ohSongcast repo should build again now.

Note that I've temporarily removed the dependency on NetworkMonitor. This won't affect you if you just want to use WavSender.

Thanks Simon, that worked...

Hello Simon, I have managed to build ohSoncast on a Raspberry pi but not on my Linux-x86 pc. I get(with -Werror removed)

I've committed fixes to all the warnings (which were all caused by recent versions of gcc flagging the lack of virtual destructor as suspect).

I can't reproduce the linker errors using gcc v4.7. They all concern functions that should exist in libpthread. ohSongcast tries to link to this (see the definition of link in Makefile). You could try editing this to use -pthread instead or editing Common.mak to add -pthread at the end of the command line instead.

[paulw]

Hi Simon thanks. I started everything from scratch and now (with the pthread amendment) it goes as far as
ohSongcast/Songcast.cs

Executables such as WavSender are built but do not work at the moment.

The whole process I followed from this thread and the README's
is :-
git clone https://github.com/openhome/ohNet.git
git clone https://github.com/openhome/ohdevtools.git
git clone https://github.com/openhome/ohNetmon.git
git clone https://github.com/openhome/ohTopologygit
cd ohNet
make all debug=1
cd ../ohNetmon
./go fetch --debug ohNet
./go fetch --debug ohWafHelpers
./waf configure --ohnet=../ohNet --debug
./waf build
cd ../ohTopology
./go fetch --debug ohNet
./go fetch --debug ohWafHelpers
./waf configure --ohnet=../ohNet --debug --dest-platform=Linux-x86
./waf build
cd ../ohSongcast
make
is this correct?
Thanks Paul

ohSongcast contains a mixture of C++ and C# code. The build failure is from a C# exe. You'll need to have mono installed to build this on Linux.

If you want to proceed without mono, you could be more specific about what to build. e.g.

make WavSender

to build WavSender.elf and its dependencies only.

Yes, that looks spot on. What happens when you try to run WavSender?

[paulw]

Simon , I have mono installed. I built WavSender and ZoneWatcher separately. They both seem to work but I got no sound from my DS which kept disappearing from kinsky.

[paulw]

Simon, you were right. I found mono-complete which added some more packages. Now it compiles. Thanks

When the DS disappears from Kinsky, does it's front panel go blank then show a single flashing dot for a few seconds? If it does, the DS has crashed and is rebooting. This would point to a bug in WavSender.

Let me know if this is the case and I'll try to reproduce/debug it.

[paulw]

No the DS does not reboot. No sound as yet, will keep working on it. BTW it took a long time for the Linux-x86 to show up as a songcast source - any hints as to why this may be?
