Hi all,

Linrad is an X11 program by Leif Asbrink for use with SDR (SoftwareDefined Radios)

Linrad

As an amateur radio entusiast I am very interested in this piece ofsotfware. It is originally written for Linux and Windows (MinGW). I havecompiled under Linux with no effort over the years, it is written forLinux and compiles out of the box without problems.

In my ignorance I thought it would compile under NetBSD the same way,but I was too optimistic. :-(

Has anybody had luck compiling it under NetBSD? I have seen that FreeBSDhas an outdated version port but only for amd64 and i386 only. It wouldbe great to run this program in NetBSD, and in particular in theRaspberryPi, for example, to be able to use the radio receivers remotely.

I have tried to compile it myself in the RPi4 but I have not succeeded.It uses the GNU ./configure autoconf programs but I cannot pass thefirst steps.

./configure has problems with NetBSD /bin/test program. I have installedGNU coreutils and changed manually the routes in .configure script to/usr/pkg/gnu/bin/test to overcome that:

To generate servers (daemons) run ./configure --with-server
rpi4-netbsd$

./configure script finishes ok. I issued "make xlinrad64" but it seemsthat it needs GNUMake.



after doing "gmake xlinrad64":



rpi4-netbsd$ gmake xlinrad64

I removed #include <linux/fb.h> in xmain.c:

#if DARWIN == 0
#include <linux/fb.h>
#endif
#endif
#include <sys/mman.h>
#include <locale.h>
#include <sys/un.h>


Run again:

rpi4-netbsd$ gmake xlinrad64



In file included from /usr/include/ctype.h:100,
                 from xmain.c:37:

I removed "-Werror" everywhere in Makefile just to try and it startscompiling for a while until it breaks after a minute or 2:

I fixed with this:

#include "/usr/src/sys/arch/evbarm/include/cpufunc.h"

but now:

rpi4-netbsd$ gmake xlinrad64

In file included from lxsys.c:37:

/usr/src/sys/arch/evbarm/include/cpufunc.h:3:10: fatal error:arm/cpufunc.h: No such file or directory

      |          ^~~~~~~~~~~~~~~
compilation terminated.
gmake: *** [Makefile:2151: lxsys.om] Error 1

I tried to fix it but I entered in an endless loop of new compilationproblems. I definitely do not have enough knowledge to make it work. Iam starting thinking that this is a very complicated task. Please let meknow what you think about it, if you think there are chances to make itwork or it is a complete waste of time.



Thanks so much in advance.
Regards.
Ramiro.
