Cross compile of chan_quectel failed because of C compiler

Hello everyone,

I recently wanted to build an Asterisk based VoIP GSM gateway using the Banana Pi R64 open source router and the Quectel EC25 modem. I built my own OpenWRT image and configured the modem so I am able to send and receive calls and messages through a terminal (e.g. minicom). I can also use Asterisk to create SIP phones and call other SIP phones with them. Now i needed to integrate the modem directly into Asterisk.

I saw an Asterisk channel driver on GitHub (https://github.com/t4rd15/asterisk-chan-quectel) for the EC25 which is a fork of the channel driver for Huaweii based USB modems.

I wanted to cross compile the channel driver for OpenWRT which I saw the creator did for the MIPS architecture but I have not been able to do it for a few days now. I followed the OpenWRT Cross Compile tutorial and I used this command to start cross compilation with autotools:

./configure --with-astversion=18.5.1 --build=x86_64-pc-linux-gnu --host=aarch64-openwrt-linux

The output was:

checking build system type... x86_64-pc-linux-gnu
checking host system type... aarch64-openwrt-linux-gnu
checking target system type... aarch64-openwrt-linux-gnu
checking for a BSD-compatible install... /usr/bin/install -c

The config.log contained:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by chan_quectel configure 1.1, which was
generated by GNU Autoconf 2.69.  Invocation command line was

If anyone can help I'd be really thankful. This is my first time doing a larger project on Linux based systems.
