Complie SuperC mmlc for ARM Platform

[tcdw]

I bought an Orange Pi One, which uses an armv7l professor and running Debian stretch.

I want to complie mmlc on it for some reasons, so I did that:

1. Installed cmake, make and clang via apt-get install
2. Installed wla-dx you provided and set $PATH properly
3. Modified the Makefile like this:

############################################################
# Makefile for SuperC mml compiler
############################################################

#DEBUG  = 1
CLANG   = 1
#WIN32  = 1
#x86    = 1

TARGET  = mmlc

ifdef CLANG
ifdef WIN32
TARGET  := $(TARGET).exe
CC  := i686-w64-mingw32-clang
LD  := i686-w64-mingw32-clang
else
CC  := clang
LD  := clang
endif
else
ifdef WIN32
TARGET  := $(TARGET).exe
CC  := i686-w64-mingw32-gcc
LD  := i686-w64-mingw32-gcc
else
CC  := gcc
LD  := gcc
endif
endif

LDFLAGS := -lz

ifdef DEBUG
CFLAGS  = -Wall -g -O0 -DDEBUG
else
CFLAGS  = -Wall -O2
LDFLAGS += -s -Wl,--gc-sections -Wl,--discard-all
endif

ifdef WIN32
CFLAGS += -D_WIN32 -I../../zlib-1.2.8
LDFLAGS += -D_WIN32 -L../../zlib-1.2.8
OBJCOPY := i686-w64-mingw32-objcopy
else
OBJCOPY := arm-linux-gnueabihf-objcopy
endif

ifdef x86
CFLAGS += -m32
LDFLAGS += -m32
OBJFLAGS = -I binary -O elf32-i386 -B i386
else
OBJFLAGS = -I binary -O elf32-littlearm -B arm
endif

#LDFLAGS    = -Wl,--gc-sections -Wl,--no-define-common -Wl,--discard-all

OFILES   = mmlc.o compile.o mmlman.o binaryman.o errorman.o spc.o timefunc.o pathfunc.o snsf.o address.o
OFILES  += md5.o snes.o
PRECOMPILE_HEADER = gstdafx.h

.PHONY: all clean
all: $(TARGET)

$(TARGET): $(PRECOMPILE_HEADER).gch $(OFILES) Makefile
    $(LD) $(OFILES) $(LDFLAGS) -o $@

.SUFFIXES: .c .o
.c.o:
    $(CC) -MMD -c $(CFLAGS) $<

snes.o: snes.bin
    $(OBJCOPY) $(OBJFLAGS) $< $@

snes.bin: ../snes/snes.bin
    cp $< $@

../snes/snes.bin:
    make -C ../snes

$(PRECOMPILE_HEADER).gch: $(PRECOMPILE_HEADER)
    $(CC) $(CFLAGS) $<

clean:
    rm -f $(TARGET) $(OFILES) $(OFILES:.o=.d) $(PRECOMPILE_HEADER).gch snes.bin

-include *.d

4. run make

Then it give me this:

clang -Wall -O2 gstdafx.h
clang -MMD -c -Wall -O2 mmlc.c
clang -MMD -c -Wall -O2 compile.c

make -C ../snes

Thanks for the report. It is a problem of "extern" in snsf.c. It is troublesome to take fundamental solution measures, so I'll temporarily deal with it for the moment.

I committed the modified source. If you want to compile for ARM, please exclude comment out on line 11. If you don't seem to be able to compile, please tell me the result of executing the following command. arm-linux-gnueabihf-objdump -t snes.o

[tcdw]

Now it works properly with my modified Makefile! I really appreciate it.
