Makefile.gnu

#
# Classic makefile for SmokeRand.
# Supports GCC and Clang (as Zig CC) compilers.
#
# Usage:
# make -f Makefile.gnu
# make -f Makefile.gnu PLATFORM_NAME=GCC
#
# Supported platforms: GCC, GCC32, DJGPP, MINGW-HX, ZIGCC
# Note: GCC includes MinGW and MSYS.
#
# DJGPP platform compiles all generators as DXE3 modules using the dxe3gen
# experimental linker supplied with DJGPP.
