DJGPP Cross Compiler 12.2.0 Fails to Recognize "certain" Parameters in FFmpeg Source Code
Hi,
I am using the DJGPP cross compiler 12.2.0, developed by Andrew Wu, github, to build the FFmpeg source code, and it's failing to recognize certain parameters and the script I used to build FFmpeg source code follows:
#!/usr/bin/env bash
# Path to DJGPP cross compiler
export DJGPP_PREFIX="/Users/owner/djcc"
# export DJGPP_PREFIX=${DJGPP_PREFIX-/Users/owner/djcc}

The "no such parameter", observed in "libavformat/network.h", has now shown up in
"/libavformat/avio.c", giving credence to starting this thread:
