# Makefile for cross compiling HttpDos for FreeDOS/MS-DOS
# All compilation was done with DJGPP 12.2.0 built from https://github.com/andrewwutw/build-djgpp
# ./build-djgpp.sh --target=i586-pc-msdosdjgpp --prefix=/home/ilu/cross all
# make sure the DJGPP toolchain is in your path (i586-pc-msdosdjgpp-XXX)!
