Stepping through the PKGBUILD steps manually, most of it works fine. However it looks like the project used to be built with an older compiler that was less strict about C++ narrowing conversions.

Changing the make command to the following worked for me.

make -j3 CXX_FLAGS="-Wno-narrowing -fPIC"

This will tell the compiler to ignore the narrowing warning, and the package should build successfully.

The problematic line of code in the project is in p25_frame_assembler.cc (line 42), but changing the make command is much easier than changing this line and dealing with the ripple effect through the rest of the code.

gcc 6 and up compilers has a problem compiling. But that is not the only issue I found out after getting everything compiled. The depends gnuradio and gnuradio-osmosdr are now compiled with gtk3 and the op25 author as I have been told on their forumm has custom built widgets coded for gtk2 and he has no intrest at this time upgrading his code as he is running ubuntu 14.2 LTS. What I finally did was to install a minimum linux mint 17.3 on my hard drive with op25 completely working and then run it under arch-chroot / xhost using a script:

#!/bin/bash
sudo mount /dev/sdb6 /mnt/chroot
xhost +
sudo arch-chroot /mnt/chroot

Once in chroot run another script to start op25:

#!/bin/bash
cd /root/src/op25/op25/gr-op25_repeater/apps
./scope.py --args rtl=0 -N LNA:46 -S 2048000 -f 856.1875e6 -o 15.0e3 -v 0 -V -q -2 -T trunk.tsv

I know this is crude but I got tired of messing with this.

During build I get:

gr-op25_repeater/lib/imbe_vocoder/pitch_est.cc:60:1: error: narrowing conversion of ‘32970’ from ‘int’ to ‘Word16 {aka short int}’ inside { } [-Wnarrowing]
