Thank you very much Michael, I am finding that this is more difficult 
than I had originally imagined. In some ways I've been a little naïve. 
There must be many specific Linux-dependent things in the code. It can 
deal with various models of receivers. Mine (Afedri-SDR Net) is 
exclusively used through the network but others are controlled through 
USB and receive data through it. Also and in the case of conventional 
radio receivers, you can use the sound card to digitize the audio. That 
I think it will be another difficulty, the program can use ALSA drivers 
directly or even using Portaudio. Many nightmares...

The code can even compile a Windows version using MinGW tool:


rpi4-netbsd$ gmake


II------  When running under Microsoft Windows  -------II
II  Install nasm and mingw32 in the folder C:\mingw32  II
II  Use configure.exe, then make.bat to get linrad.exe II
II-----------------------------------------------------II

-------------- When running under Linux	-----------------------

To produce a Linrad executable, do one of the following:
make xlinrad    - Linrad (32 bit) for Linux
make xlinrad64  - Linrad (64 bit) for Linux
make linrad.exe - Cross compile for Windows. mingw32 needed.
make linrad64.exe - Cross compile for Windows. mingw32 needed.

To produce scripts that install modules at boot time.
(Reboot after sucessful completion of these commands)
make svgalib    - For svgalib to run as a normal user.
                    svgalib_helper must be in/etc/linrad/xxxx
make sdr14      - To use the SDR-14 or SDR-IQ from RFSPACE
--------- other commands: make configure.exe, make sim ---------
----------------------------------------------------------------
rpi4-netbsd$



Many years of coding cannot be adapted to NetBSD in a few minutes. Also 
I think that the author has not got any NetBSD experience just in case I 
could give him access to my NetBSD system to play with it.

Many pieces of code that must be adapted for NetBSD and work together. 
It can work with plain X11 (no graphical programming toolkits) or 
framebuffer.

Anyway, I will tell you what the author of the program tells me if he 
answers me,  but I am afraid that I will inevitably have to abandon it.

Many thanks, anyway I am learning many things.

Regards.
Ramiro.
