make error fix Ubuntu 11.10

[Sinager]

Hi All,
whoever wants to upgrade to Ubuntu 11.10 has two problems to face:

1- missing /dev/dsp devices since Ubuntu 10.10: a patch was submitted in another thread (http://forums.radioreference.com/digital-voice-decoding-software/220493-fix-ubuntu-10-10-a.html) to route your audio via padsp however I prefer to recompile my kernel with OSS support in order to run other old software (MultiMon to name one). Feel free to ask if you need guidance.

2- structure of the Makefile now has to be more precise, putting libraries to be included in the script at the end of each compiling command. This is what leads to errors like the ones described here: http://forums.radioreference.com/digital-voice-decoding-software/224276-dsd-install-error.html
I've made a few changes to the MBE and DSD Makefiles to follow the new rules and now they compile fine: I'm attaching them below. Just in case here's also an alternative download on my website:
http://www.tarapippo.net/linux/dsd-makefiles.tar.gz
Usage:
- remove "Makefile" from both the DSD and MBE directories
- replace them with the ones provided, renaming both to "Makefile", each in its own directory

Thank to DSDAuthor for the fine tool!

I was change files Makefile and I add audio patch for file dsd_audio.c

Now working that:

Its on Ubuntu 11.10. Any ideas yet?

Just to rule out the obvious: did you compile and install MBElib before getting to DSD?

 

[corbintechboy]

If Ubuntu has OSS available, install it. Else:

 sudo ln -s /where/ever/sound/card/is/located /dev/dsp

Fixed without patch!

Yes, i have installed mbelib, it instalation an compilation was absolute succesfull.

I dont have oss stricte, i have packet "pulse-oss" only, it receiving calls to oss from programs and
redirecting it to pulseaudio system

 

[Sinager]

I'm positive OSS has nothing to do here (btw you can't just install OSS in the latest Ubuntus as the support is disabled in kernel).

It's the math lib not properly linked in at MBE compiling time: it won't fail but any error will surface only at the time you build DSD.

I think I fixed it in my build after reading this thread, however don't know why it didn't get into my makefile: "Undefined Reference" to pow and sqrt even though math.h header is there

I'm not at home with my "radio" pc at the moment, so I can't check hand-on.
Try changing
CFLAGS = -O2 -fPIC
into
CFLAGS = -O2 -fPIC -lm

All the best.

Hi,
to check the process I've just recompiled DSD on my netbook using the attached Makefiles and everything went fine. No need for further changes.
Again just in case, may I suggest to try again following these steps:
- get into MBE directory
- "make clean"
- "make"
- "sudo make install"
- "sudo ldconfig"
- get into DSD directory
- "make clean"
- "make"
- "sudo make install"
