Problem compiling ch2i/rpi-shield packet forwarder

Gateways Raspberry Pi Gateways
1

I am attempting to get my gateway to work (Raspberry Pi 3, ic880a, with the ch2i shield in-between).

I followed the instructions from https://github.com/ch2i/iC880A-Raspberry-PI , which led me to https://github.com/ch2i/ic880a-gateway/tree/ch2i-rpi-shield . As per the instructions here, I’m trying to install the packet forwarder:

  $ git clone -b ch2i-rpi-shield https://github.com/ch2i/ic880a-gateway.git ~/ic880a-gateway
  $ cd ~/ic880a-gateway
  $ sudo ./install.sh

However, the compilation fails:

make[1]: Leaving directory '/opt/ttn-gateway/lora_gateway/util_spectral_scan'
/opt/ttn-gateway ~/ic880a-gateway
/opt/ttn-gateway/packet_forwarder /opt/ttn-gateway ~/ic880a-gateway

It does look like I’m missing a prerequisite, but I cannot figure out which one (I did install bcm8235, which seems to be the only prerequisite mentioned on github).

Can anyone point me in the right direction?

Thank you!

That’s strange,
looks like can’t link with math function like ceil
did the lora_gateway compiled fine ?

As far as I can tell, yes. Here is the full output from install.sh:

I just started over with a clean install of Raspbian Jessie. The issue reproduces perfectly even with a clean install.

Here’s everything I did after booting with the fresh Raspbian install:

apt-get update && apt-get install vim python3-pip python3-rpi.gpio
raspi-config (enable SPI and I2C, expand filesystem)
apt update && apt dist-upgrade 
apt-get install git-core i2c-tools
apt-get install vim python3-pip python3-rpi.gpio
reboot
git clone -b ch2i-rpi-shield https://github.com/ch2i/ic880a-gateway.git ~/ic880a-gateway
cd ic880a-gateway/
./install.sh

Indeed, lora_gateway compiles just fine, but the packet forwarder throws the exact same error. Full output included below (the only difference is that this time it had to pull the files from git):

[ Edited to add: the compilation seems to work if I manually add “-lm” to the LIBS section in each of the packet forwarders’ Makefile. However, I no longer know enough C programming to figure out whether I managed to break anything else with this change :expressionless: ]

Great, no you won’t break anything it’s just adding missing code on link stage. adding library even not used won’t hurt.

Strange I do not remember that I needed to add this one. I’ll check that soon because I need to do same thing for my new RPI Zero RAK831 shield :wink:

Great - thank you! So far it seems to work - at least I can see the heartbeat LED blinking (and occasionally the error LED :stuck_out_tongue: ). Now I have to program a client node, and see if I can get them to talk to each other :smiley:

Once again, thank you for your help!

[ Edited to add one more question - the shield has a breakout for a DHT11 sensor. But the code does not seem to include the ability to read it - only BMP280/BME280 and/or SI7021/HTU21D. Any chance that might show up in a future version? :slight_smile: ]
