Failed to build libwebsockets

[flo17]

Hi everyone,

I’m encountering an issue with using MQTT (mosquitto) on a RUT360 router. The broker works perfectly over the MQTT protocol, but it doesn’t support Websockets, which is necessary if you want to publish messages from a web page.

I edited the /etc/mosquitto/mosquitto.conf file to enable Websockets support, but when I run the command mosquitto -c /etc/mosquitto/mosquitto.conf, I get the following error message:

1724916990: Error: Websockets support not available.
1724916990: Error found at /etc/mosquitto/mosquitto.conf:284.

After searching through several posts, I found recommendations to add the libwebsockets library. Since this library isn’t available via opkg, I decided to recompile the image. I’ve done this before without any issues, so I followed the same process with the following additional steps:

1. Ran ./scripts/feeds install libwebsockets
2. Opened make menuconfig, checked the box for libwebsockets-full, and saved the configuration
3. Ran make

However, during the build process, I encountered the following error:

I’m not sure how to resolve this issue. Any insights or suggestions would be greatly appreciated!
