CLDC cygwin 交叉编译 Makefile 设置方法

1. E:/j2me_cldc/api

JAVAC =javac -source 1.4

2. E:/j2me_cldc/kvm/VmWin/build

ifeq ($(GCC), true)

CC = gcc

LD = gcc

LIBS= -luser32 -lgdi32 -lkernel32 -lmsvcrt -lwsock32

-I$(TOP)/kvm/VmExtra/h -I$(TOP)/jam/h -I$(TOP)/kvm/VmCommon/src

CFLAGS = -mno-cygwin -mcpu=i386 -Wall $(CPPFLAGS) $(ROMFLAGS) $(OTHER_FLAGS)

DEBUG_FLAG = -g

OPTIMIZE_FLAG = -O2

FP_OPTIMIZE_FLAG =

OUTPUT = -o

LINKER_OUTPUT = -o

LDFLAGS = -mno-cygwin

else

CC= "/cygdrive/C/Program Files/Microsoft Visual Studio/VC98/BIN/cl.exe"

LD= "/cygdrive/C/Program Files/Microsoft Visual Studio/VC98/BIN/link.exe"

LIBS= user32.lib gdi32.lib kernel32.lib wsock32.lib

CPPFLAGS = -DWIN32 -I$(TOP)/kvm/VmCommon/h -I$(TOP)/kvm/VmWin/h /

-I$(TOP)/kvm/VmExtra/h -I$(TOP)/jam/h /I "C:/Program Files/Microsoft Visual Studio/VC98/ATL/INCLUDE" /I "C:/Program Files/Microsoft Visual Studio/VC98/INCLUDE" /I "D:/Program files/Java/jdk1.6.0_10/include"

CFLAGS= -nologo $(CPPFLAGS) $(ROMFLAGS) $(OTHER_FLAGS)

DEBUG_FLAG= -Zi -Od

OUTPUT = -Fo

LINKER_OUTPUT = -out:

LDFLAGS =-libpath:"C:/Program Files/Microsoft Visual Studio/VC98/ATL/LIB" -libpath:"C:/Program Files/Microsoft Visual Studio/VC98/LIB"

3. E:/j2me_cldc/tools/preverifier/build/win32

ifeq ($(DEBUG), true)

DEBUG_FLAG = -g

endif

OPTIMIZE_FLAG = -O2

OUTPUT = -o

LINKER_OUTPUT = -o

else

CC= "/cygdrive/C/Program Files/Microsoft Visual Studio/VC98/BIN/cl.exe"

LD= "/cygdrive/C/Program Files/Microsoft Visual Studio/VC98/BIN/link.exe"

CFLAGS= -DWIN32 -nologo $(OTHER_FLAGS) /I "C:/Program Files/Microsoft Visual Studio/VC98/ATL/INCLUDE" /I "C:/Program Files/Microsoft Visual Studio/VC98/INCLUDE" /I "D:/Program files/Java/jdk1.6.0_10/include"

CPPFLAGS +=

DEBUG_FLAG =

LDFLAGS = -libpath:"C:/Program Files/Microsoft Visual Studio/VC98/ATL/LIB" -libpath:"C:/Program Files/Microsoft Visual Studio/VC98/LIB"

4. E:/j2me_cldc/tools/jcc

JAVA = java

JAVAC = javac -source 1.4

JAR = jar

5. 编译方法

用 cygwin 在 E:/j2me_cldc/build/win32 下执行 make 命令对 KVM 进行编译 ；用 make clean 命令清楚编译文件。
