Hi folks,

a recent thread at comp.arch.embedded showed the question on any suitable 8051 emulator for use under Linux. Except for a flamewar, it didn't produce much useful output. But it renewed my interest as I'm looking for a suitable emulator for ages.
Now I found emu51 at Sourceforge (http://emu51.sourceforge.net/) which comes as sources but for Windows only.

I toyed around a bit and I managed to compile emu51 under GNU/Linux.
This emulator is very early alpha but better than nothing and free software, free as in freedom and not as free beer ofcourse.
As it comes as sourcecode + Windoze binary only, I altered the Makefile so it now compiles under GNU/Linux as long as you have a working installation of the Allegro library.
See the altered Makefile at the bottom of this posting.

I know this is not a commercial grade emulator but I hope this proves useful for hobbyists and students like me who cannot afford commercial grade software for 100EUR and more.

# Project: emu51
# Makefile adopted for GNU/Linux by Matthias Arndt <marndt@asmsoftware.de>


CPP  = g++
CC   = gcc
OBJ  = emu51.o
LINKOBJ  = emu51.o
LIBS =  `allegro-config --libs`
INCS =  `allegro-config --cflags`
CXXINCS =  `allegro-config --cflags`
BIN  = emu51
CXXFLAGS = -O3 $(CXXINCS)
CFLAGS = -O3 $(INCS) 

.PHONY: all all-before all-after clean clean-custom

all: all-before $(BIN) all-after


clean: clean-custom
	rm -f $(OBJ) $(BIN)

$(BIN): $(OBJ)
	$(CPP) $(LINKOBJ) -o $(BIN) $(LIBS)

emu51.o: emu51.cpp
	$(CPP) -c emu51.cpp -o emu51.o $(CXXFLAGS)

I hope this helps a bit!

cheers,
Matthias
