building lora-packet-forwarder error

[liangyuan64]

Hi xueliu

openwrt 18.06， It can be compiled the lora_pkt_fwd package but when I compiled the lora_pkt_fwd package wiht lede 17.01.4, there were many errors. Could you help me solve the problem? Thanks for your time.

Hello, This a strange problem. You see this error because Make can not find libloragw it needs. But when you select lora_pkt_fwd libloragw should be automatically selected. So please have a check that libloragw is really selected.

[liangyuan64]

I'm sure libloragw has been selected ,Trying to recompile but the problem still exists. I'll close comment first, and if I solve this problem, I'll post a solution

[xeeeeeeeee]

Does anybody have an update on this? I'm having the same problem.

I can compile the libloragw fine, but if I had the pkt_fwd I get this errors.

I will check it in this week.

you are right. Now the library dependence is handled by CMake. It do not matter when lora-gateway-hal != libloragw.

Hello,

Please update the lora-feed repo to the latest version. Try to run following command:

make package/lora-packet-forwarder/clean
make package/lora-packet-forwarder/compile V=s

and have a look the CMake initialization part e.g. my compile log:

In the last few lines you can see that the libloragw is found.

Hi,

I try to install openwrt with the package forwarder, but this error appears.

Package lora-packet-forwarder is missing dependencies for the following libraries: libloragw.so.0 Makefile:63: recipe for target '/home/teste/openwrt/bin/packages/aarch64_cortex-a53/lora/lora-packet-forwarder_4.0.1-1_aarch64_cortex-a53.ipk' failed make[3]: [/home/teste/openwrt/bin/packages/aarch64_cortex-a53/lora/lora-packet-forwarder_4.0.1-1_aarch64_cortex-a53.ipk] Error 1 make[3]: Leaving directory '/home/teste/openwrt/feeds/lora/lora-packet-forwarder' time: package/feeds/lora/lora-packet-forwarder/compile#0.38#0.26#0.69 package/Makefile:107: recipe for target 'package/feeds/lora/lora-packet-forwarder/compile' failed make[2]: [package/feeds/lora/lora-packet-forwarder/compile] Error 2 make[2]: Leaving directory '/home/teste/openwrt' package/Makefile:103: recipe for target '/home/teste/openwrt/staging_dir/target-aarch64_cortex-a53_musl/stamp/.package_compile' failed make[1]: [/home/teste/openwrt/staging_dir/target-aarch64_cortex-a53_musl/stamp/.package_compile] Error 2 make[1]: Leaving directory '/home/teste/openwrt' /home/teste/openwrt/include/toplevel.mk:216: recipe for target 'world' failed make: [world] Error 2

I installed libloragw before the packet forwarder but the libloragw dependency error. I already have the new version of packet forwarder and I already executed it

make package/lora-packet-forwarder/clean make package/lora-packet-forwarder/compile V=s

and nothing happens.

What will be the problem?

Thank you

Hi, from the error log I guess that you did not use the latest code. You may clean the build tree and try a again.

[xueliu]

Also having the same problem. Here's the log, https://www.dropbox.com/s/rdd4ajdr04vpl89/loragw.txt

It is strange that the line

-- libloragw library:

is empty.

[xueliu]

I guess that the problem may be dependence conflict of lora-packet-forwarder between the mainline and my feed. My patch for lora-gateway-hal is already accepted by OpenWRT. Its library package calles libloragw. In order to support the pico gateway in this local feed and avoid the name conflict, I change the library name to the lora-gateway-hal and also the dependence of lora-packet-forwarder. But the offical lora-gateway-hal does not been changed and it has a higher priority. So If you use the latest official feed and together with this lora-feed. The compile of lora-packet-forwarder will complain the missing of lora-gateway-hal (libloragw).

In order to solve the problem, I add patches to revert the lora-gateway-hal library name back to libloragw. I will change the library name of pico-hal to libpicogw to avoid the conflict.

so please clean, update and try again.

[xeeeeeeeee]

I tried it again this morning with a clean build and I'm still having the same issue.

[pacmenDE]

hi, i´ve tried too to compile the packet_forwarder. But i get the same errors descriped in this issue. Anybody knows how to resolve it? Thanks Patrik

[pacmenDE]

Here is my solution for the lora gateway and packet forwarder.... https://github.com/pacmenDE/openwrt_MT7688_loragw_pkt_forwarder

[xeeeeeeeee]

Hi, how did you managed to fix the issue? I need to compile it for another architecture.

[xueliu]

Hi, how did you managed to fix the issue? I need to compile it for another architecture.

Which OpenWRT version do you use ?

[xueliu]

Hello all,

I finally reproduced this problem in OpenWRT 18.06.04. But I really don't know why CMake pkg_search_module() only found the head files but no libraries. So I add a third method (Findloragw.cmake) to locate the headers and libraries. I hope this time the patch can work.

[pacmenDE]

Hi, i hope, i can help to resolve the problem for compile the packet_forwarder!

i´am not a developer, but i´ve found a functional openwrt V15.05 on github from rakwireless. https://github.com/RAKWireless/RAK2247-RAK833-LoRaGateway-OpenWRT-MT7628 with copy and paste of some files i am able to produce openwrt 15.05 with difference architecture running lora GW und pkt_fwd.:-) But i have no HW to test it...:)

I tried to compile my solution with V17 and V18 but i get on both versions many compile errors too!

I hope i can help you with my tip and you can resolve your problem.:-) Patrik
