installing an ipk package and incompatible with the architecture error

  • optech

    Hello all,

    I would like to install chirpstack gateway bridge application on my gateway which has Omega2S+.

    I follow the instructions below:

    wget https://artifacts.chirpstack.io/vendor/dragino/LG308/chirpstack-gateway-bridge_3.11.0-r1_mips_24kc.ipk

    opkg install chirpstack-gateway-bridge_3.11.0-r1_mips_24kc.ipk

    Result is:

    Unknown package 'chirpstack-gateway-bridge'.
Collected errors:
 * pkg_hash_fetch_best_installation_candidate: Packages for chirpstack-gateway-bridge found, but incompatible with the architectures configured
 * opkg_install_cmd: Cannot install package chirpstack-gateway-bridge.

    I see architecture is mipsel_24kc for both system and package.. What would be the reason of this issue?

    root@OpenWrt:~# opkg print-architecture
arch all 1
arch noarch 1
arch mipsel_24kc 10

    the conf file "/etc/opkg.conf" :

    dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay
option check_signature

    @optech @tjoseph1 is correct, this ipk is mispackaged. An IPK is just a set of tgz inside a tgz, so you can extract the files and run the binary and the error becomes self-evident. Best to contact the author or recompile the code.

    I have the sources here:
    https://www.chirpstack.io/gateway-bridge/community/source/

    I recompiled it but it compiles as big endian as you said. So do you think is there a way to compile as little endian?

    By the way, i also ask this issue to author in chirpstack community forum. no answer yet.

    mipsel ipk is here:
    https://disk.yandex.com/d/bDtdR4j251cKIQ
    Filename: chirpstack-gateway-bridge_3.11.0_mipsel_24kc.ipk

    I couldn't find the "3.11.0-r1" in the github repo
    ..
    v3.1.0
    v3.10.0
    v3.10.0-test.1
    v3.11.0
    v3.11.0-test.1
    v3.2.0
    ..
    so, I picked 3.11.0

    omega# /etc/init.d/chirpstack-gateway-bridge status
    Syntax: /etc/init.d/chirpstack-gateway-bridge [command]
    Available commands:
    start Start the service
    stop Stop the service
    restart Restart the service
    reload Reload configuration files (or restart if service does not implement reload)
    enable Enable service autostart
    disable Disable service autostart

    Thanks.

    @tjoseph1 Thank you for packing for me šŸ™‚ the information you gave me was useful.. Thanks again...

    @tjoseph1 I tried to run follows:

    /etc/init.d/chirpstack-gateway-bridge enable

    /etc/init.d/chirpstack-gateway-bridge start

    It says "Starting chirpstack-gateway-bridge" but there is no start an instance as proccess.. Could you had a chance to test it on Omega after compiling?

    @optech add PROCD_DEBUG=1 to the top of your init script to log more info about the process

    I did it but still there is nothing about chirpstack gateway bridge ! šŸ˜•

    @optech Post your init script please, it will log whatever the script results are. Check the log again using:

    logread | grep -i chirpstack

    What could be the reason of this difference? what do you think? By the way, i loaded a custom build openwrt firmware 19.07.. Is that can be the reason?

    @optech
    "a custom build openwrt firmware 19.07 ..Is that can be the reason"
    May be..

    You could flash the omega2 with onion build and try. I have provided my onion os version; any recent version should work.

    "/opt/chirpstack-gateway-bridge/chirpstack-gateway-bridge" is the only "arch dependent" (binary) file in the ipk.

    $ file build/chirpstack-gateway-bridge
    build/chirpstack-gateway-bridge: ELF 32-bit LSB executable, MIPS, MIPS32 version 1 (SYSV), statically linked, Go BuildID=0A8....

    You can also try running it from command prompt using the options that "/etc/init.d/chirpstack-gateway-bridge" script uses with "start" parameter.

    ("/etc/chirpstack-gateway-bridge/chirpstack-gateway-bridge.toml" contains the settings, it seems)

    Thank you.

    @tjoseph1 thank you very much for your help.
    I loaded onion build firmware and tried it again then it works. šŸ™‚

    But it doesn't work on openwrt 19.07 custom build.. I really wonder what would be the reason of this issue?

    Here is the build which chirpstack gateway bridge doesnt work on..:

    @optech
    Can you pls replace the /opt/chirpstack-gateway-bridge/chirpstack-gateway-bridge in your openwrt 19.07 with this file:
    https://disk.yandex.com/d/C_6-fmcDtqXIGA and then try running it?

    It is a zip file, that unzips to "chirpstack-gateway-bridge" exe.

    Thank you.

    @tjoseph1 Thank you for your help. I was on a vacation sorry for late...

    I replaced "/opt/chirpstack-gateway-bridge/chirpstack-gateway-bridge" with the file that you sent. But result is same, dont work and so no ram change(on openwrt 19.07)..
    Do you have another idea to find the reason of this issue?

    I recompiled chirpstack gateway bridge as following the steps below:

    export GOARCH=mipsle
export GOOS=linux
make build

    root@OpenWrt:~# file /opt/chirpstack-gateway-bridge/chirpstack-gateway-bridge

/opt/chirpstack-gateway-bridge/chirpstack-gateway-bridge: ELF 32-bit LSB executable, MIPS, MIPS32 version 1 (SYSV), statically linked, Go BuildID=VcvuifmDnNysO-WpZUz5/FGFca5Lt5vpptRtlLTBo/l2QuqgekGwKVygyjsXAL/6lmuYGmDGU2RDGrxxamU, stripped

    The result is the same doesn't work on openwrt 19.07...

    @optech
    Ok. Let us start simple.
    Are you able to cross-compile the "hello_world.go" and run it in the 19.07 Omega2 with GOARCH,GOOS parameters set as above ?

    package main
    import "fmt"
    func main() {
    fmt.Println("Hello, World!")
    }

    If not, you may want to try GOMIPS=softfloat or some other options in addition to those two. Once that thing prints \"Hello, World!\", try the same options to build chirpstack-gateway-bridge.

    Thanks.

    @tjoseph1 Thank you again for your help.

    I compiled the hello world go app as following...:

    export GOARCH=mipsle
export GOOS=linux
export GOMIPS=softfloat
go build hello.go

    if i dont use "GOMIPS=softfloat", it works on openWRT 18.06 but dont work on openWRT 19.07 as giving following error:

    root@OpenWrt:~# ./hello
Illegal instruction

    with "GOMIPS=softfloat" option, it works on openWRT 19.07..

    But after seeing that, i compiled chirpstack-gateway-bridge app with same options. But it still doesnt work on openWRT 19.07 šŸ˜ž

    chirpstack-gateway-bridge$ export GOARCH=mipsle
chirpstack-gateway-bridge$ export GOOS=linux
chirpstack-gateway-bridge$ export GOMIPS=softfloat
chirpstack-gateway-bridge$ make build

    i feel near to solution but i have no idea for now.
