Arch Linux User Repository

For anyone having problem to get this running:

I used the tag 1.1.1 for the Server, so source line looks like this:

source=("simple-rt::git+https://github.com/robinpaulson/SimpleRT#tag=1.1.1" 'simple-rt@.service')

and used the apk mentioned in this issue

https://github.com/robinpaulson/SimpleRT/issues/57#issuecomment-1325692739

It works, thanks :)

note: I'm not using the official F-Droid app: https://github.com/robinpaulson/SimpleRT/issues/57#issuecomment-1325692739

The package has been updated with a new Git URL, as well as changes proposed by rcf.

Also added a post_upgrade message

Does anyone know how fix pkgver() ?

I change PKGBUILD to support all running interfaces

build() {
    cd "$srcdir/simple-rt/simple-rt-cli"
    make iface_up_sh_path=/usr/libexec/simple-rt
    for int in $(ip link show | grep "state UP" | awk -F ': ' '{ print $2}'); do
        cat "$srcdir/simple-rt@.service" | sed -e "s/%i/$int/g" > "$srcdir/simple-rt@$int.service"
    done
    rm $srcdir/simple-rt@.service
}

package() {
    mkdir -p "$pkgdir/usr/lib/simple-rt"
    mkdir -p "$pkgdir/usr/libexec/simple-rt"
    mkdir -p "$pkgdir/etc/systemd/system/multi-user.target.wants"
    install -m755 "$srcdir/simple-rt/simple-rt-cli/simple-rt" "$pkgdir/usr/lib/simple-rt/simple-rt"
    install -m755 "$srcdir/simple-rt/simple-rt-cli/iface_up.sh" "$pkgdir/usr/libexec/simple-rt/iface_up.sh"
    for service_int in $srcdir/simple-rt@*.service; do
        install -DT -m0755 "$service_int" "$pkgdir/usr/lib/systemd/system/$(basename -- "$service_int")"
    done
}

As for an actual fix I would go with something along the lines of

diff --git a/PKGBUILD b/PKGBUILD

 }

because simple-rt.service might confuse people who don't realize it's tied to one interface. Or maybe it could select the interface used by the default route, which would at least guarantee that you're getting Internet access.

With more than one active interface,

cat "$srcdir/simple-rt@.service" | sed -e "s/%i/$SIMPLERT_INTERFACE/g" > "$srcdir/simple-rt.service"

fails with

sed: -e expression #1, char 10: unterminateds' command`

as $SIMPLERT_INTERFACE ends up being multiple lines.

Alright, I implemented Unit template and its available now.

You can specify any desired interface via systemd instantiation:

sudo systemctl start simple-rt@enp5s0

simple-rt unit still available for BC. PKGBUILD scans active network interfaces and chooses first one for simple-rt unit

Please, let me know if something is wrong. Thank you

Also, net-tools was added to dependencies because original code requires ifconfig to be installed

The service file should be parameterized over the network interface:

$ diff simple-rt@.service simple-rt.service

6c6
< ExecStart=/usr/lib/simple-rt/simple-rt -i %i

> ExecStart=/usr/lib/simple-rt/simple-rt -i enp5s0
