Decoding D-Star

[robman50]

Has anyone had any success in compiling DSD to decode the mode 'D-Star'? I know for a fact that the DSD+ version will not decode the audio but only show scrambled text. Would I be better off with Windows or Linux for this? Or does anyone have an working Windows version that they would wish to share?

 

[toastycookies]

yes.

I found this but I don't know how to do 'Step 4'.

[toastycookies]

just use gcc -c to compile the individual source files then gcc -o to combine the multiple sources into your final executable.

 

[robman50]

And how do I do that? What folder would I have to be in?
I know nothing about compiling.

 

[toastycookies]

as per step #4 - folders mbelib-master and dsd-master

I don't understand it at all I'm afraid.

I don't understand it at all I'm afraid.

Did you carefully read the instructions referenced above? Incidentally, I wasn't aware of Cygwin until reading this thread, I didn't know you could put GCC on windows. I might try it out myself and see if I can this working.

 

[robman50]

Did you carefully read the instructions referenced above?.

Yes of course.
'4. Within the Cygwin command window, use gcc, to compile every .c file within the folders mbelib-master and dsd-master (subfolders can be ignored), so that you will get an .o file (object file) for each source file.'
First, I'd like to point out that there are no .c files in the dsd-master folder, they are all in the src folder, so I guess I use those?

And second it keeps saying that one of the .h files are not found.

Yeah you got it, and the header files are in the "include" directory. This is a very standard layout.

I put EVERYTHING into one folder from dsd-master and mbelib-master and I keep getting this.
'dsd.h:40:20: fatal error: mbelib.h: No such file or directory
compilation terminated.'

That file is in the directory in the same name.
So frustrating.

what CPU and version of windows are you running?

If they are close to mine I will try to compile a binary for you to use.

I am on windows 10 enterprise on a i5-6600k skylake cpu.

On Windows 7 I was able to get DSD 1.7 working, it was a bit painful (mostly because I've never used Cygwin before to compile stuff on Windows). I started with the following instructions buried in the comments of the above-referenced thread:

install libsndfile-devel, make, cmake and cpp in cygwin, extract both archives and then goto mbelib dir and type:
mkdir build
cd build
cmake ..
make
make install

then cd to dsd dir and type:
mkdir build
cd build
cmake ..
make
make install

I had to re-run the Cygwin setup program several times to add a few things it said were missing. Also, in the Cygwin terminal I had to manually compile IT++ (which isn't contained in the Cygwin package manager). Also, I copied the DSD.exe binary to "C:\cygwin\bin", because I kept getting errors about missing DLL files contained in that directory while trying to run the program from the build directory. That may not have been the "right" way to do it, but at least it got things working.

Finally, note that the windows port of DSD only accepts audio from the sound card configured as your default recording device in windows. Therefore, unlike DSD+ you cannot tell DSD to use a virtual audio cable. Rather, you must configure your raw disc. signal (i.e. from SDR#) to a VAC, and then set that VAC as your default recording device.

I am going to assume you are using DSD1.7? If so that is what Iam using and it works on my tapped scanner and with RTL-SDR dongle.

There IS a ready to run Windows version of dsd 1.7. Sorry..at work so right now cannot provide link.

Two things. First, you should re-run the Ctgwin setup.exe file, and install gcc-g++. After that, if you still the error re: " CMake no longer defines WIN32 on Cygwin!", run cmake as follows:

cmake .. -DCMAKE_LEGACY_CYGWIN_WIN32=1

Okay.. that's a start.
