Where can I find the dependency libs for packet-forwarder-test?

[andrewintw]

I use the following command to do cross-compile.

$ cross build -v --target armv5te-unknown-linux-gnueabi --release

After finish the build process, I got two binaries rf-tester and sx13xx-conf at target/armv5te-unknown-linux-gnueabi/release/.

$ file target/armv5te-unknown-linux-gnueabi/release/rf-tester
target/armv5te-unknown-linux-gnueabi/release/rf-tester: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=ebffd8069e76a2c5ec872fbe453971e4d5647228, with debug_info, not stripped

The problem is it cannot run on my target platform. I guess I need to copy the dependency libs from cross-build environment.

Where can I find the dependency libs for packet-forwarder-test?

Could you run the program on amd64 and connect to it with the packet forwarder instead?

My target device is armv5te (ARM 32 bit). Do you means the test tool is not for the target device?

Hi Sir,
As Andrew mentioned, our device is armv5te.
Do you have any ideas?

We already ported gateway-rs and gateway-mfr-rs with NO issues.
Please help us to fix the dependency issue for packet-forwarder-test.
Thanks a lot.

[lthiery]

@browanofficial I already mentioned to @andrewintw that I think it's easier to just run this on an amd64 system and connect the packet forwarder to the amd64 system.

My target device is armv5te (ARM 32 bit). Do you means the test tool is not for the target device?

You can test your target device by simply configuring packet forwarder to connect the amd64 system running the rf-tester. For example, on a local amd64 machine with IP 192.168.1.8, start the tester. Then on your armv5te system, edit global_conf.json:

"gateway_conf": {
        "server_address": "192.168.1.8",
        "serv_port_up": 1680,
        "serv_port_down": 1680,
        ...
}

Now the packet forwarder can connect to your amd64 system to run the rf-tester.

If you absolutely want to debug the cross-compilation, I need more detail:

The problem is it cannot run on my target platform.

Why can it not run? What's happening? What's the output?

The cross-compilation is ok. I got rf-tester in the target/armv5te-unknown-linux-gnueabi/release/.

The problem is rf-tester is a dynamic linking binary. I cannot run the rf-tester in my target device without copy all of the dependency libs. so I would like to know how can I get the dependency libs?

[andrewintw]

Another way is try to use static-linking in build procedure.

I had try the way on other helium tools, such as gateway-rs, gateway-mfr-rs and it works.

But when I try to use static-linking in packet-forwarder-test, it failed.

Here is what I did and the full build log.

env setup:

$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
$ cargo install cargo-make
$ cargo install cross
$ sudo apt update && sudo apt install -y docker.io && sudo usermod -aG docker $USER

change the rustflags:

$ git clone https://github.com/helium/packet-forwarder-test.git
$ cd packet-forwarder-test/
$ vi .cargo/config.toml 

[target.armv5te-unknown-linux-gnueabi]
rustflags  = [
    "-C", "target-feature=+crt-static",
    "-C", "link-args=-static",
]

[term]
verbose = true

then use cross command:

@andrewintw Sorry for my extreme delay. I went on vacation and lost track of this thread.

It seems the important part of the error is

Awesome!
I' trying to use it. I've change the global_conf.json file to point the IP to my LoRa gateway but getting messages below.

./rf-tester --region US915

Are these messages errors?
Why Mac existed, but IP updated?
What should be the gateway_ID in the config file?
Maybe something wrong with it beause it looks like an IP address in it.
By the way, the Mac address isn't mac address of my gateway, the mac length except AA and BB is shorter than real Mac address.

How can I know if the test is OK or not? If I connect a Spectrum Analysizer to the hotspot antenna port, should I see output on the screen? What's a good result? Is there any sample log?
Thanks!
