上一回合有说到打造自己的j2me和找到了phoneme这个开源项目。
经过这几天地下工作的努力终于是有所结果。（为什么说是地下呢？这可不好在此公开）
在linux下成功编译phoneme feature mr3的arm和x86平台，并可以成功在cldc_vm上运行Hello Java
arm平台在自己的sky2400和公司的marvell, storlink平台都测试通过
不过现在也只是完成了cldc这一层，虽然midp也成功编译，但是从makefile来看也只是omap730平台的
midp层是与自己的平台息息相关的东西，这个才是真正要做移植工作的地方
比如显示是用哪种接口，qt? directfb? 按键等等
下面先说说编译CLDC和MIDP吧，移植MIDP以后有机会再说
1，环境：
机器：x86 pc or vmware
系统: Debian GNU/Linux 4.0 r3 Etch
2，准备：
1) 解包需要命令：unzip，如没有且可以上网可以：apt-get install unzip
2) 如果编译MIDP需要库：libxp6, libxtst6，可以如此安装：apt-get install libxp6 libxtst6
因为编译的是使用fb，这种比较简单依赖的库也最少，如果是qt或者directfb依赖的更多些
3) 如果不编译MIDP可以使用jdk 5，否则一定要jdk 1.4。
（本想直接使用jdk 5来处理的，可是研究了一小段时间还是不行）
jdk 5和jdk 1.4可以只安装后者，或者两者都安装。
安装jdk 5可以直接：apt-get install sun-java5-jdk
jdk 1.4就没这么好办了，得到网上下载来安装，可参考如下步骤：
wget http://mirrors.dotsrc.org/java-linux/JDK-1.4.2/i386/03/j2sdk-1.4.2-03-linux-i586.bin ##下载安装包
chmod +x j2sdk-1.4.2-03-linux-i586.bin ##加上可执行权限
./j2sdk-1.4.2-03-linux-i586.bin ##进行安装
mv j2sdk1.4.2 /opt ##移动/opt目录下
4) 下载phoneme feature mr3
wget http://download.java.net/mobileembedded/phoneme/feature/phoneme_feature-mr3-rel-src-b01-17_jul_2008.zip
3，编译脚本（又是脚本，懒人的好东西啊）

################## file end build-phoneme.sh ####################
4，patch和说明
1) javac相关
phoneme需要的是jdk 1.4，因此很多makefile(很多java源码也)写的时候没有考虑到现在都用jdk 5了
也有少许几个makefile考虑到了兼容性的问题编译时使用了如：
javac -source 1.4 -target 1.4
以下是我修改以上这种情况的文件：
a) phoneme_feature/tools/makefiles/common_defs.gmk 修改30行
b) phoneme_feature/pcsl/tools/sosProxy/GNUmakefile 修改35行
c) phoneme_feature/cldc/build/share/tools.make 修改28行
d) phoneme_feature/midp/build/common/makefiles/cdc_vm.gmk 修改178行
e) phoneme_feature/midp/build/share/libdefs.gmk 修改76行
其中，phoneme_feature/midp/build/common/makefiles/Defs.gmk本来是修改168行的
但是修改后倒是总也编译midp不通过，老是报以下的错误，而不修改就OK，暂时不明白为什么
/home/fi9/j2me/phoneme_feature/midp/build/linux_fb_gcc/../../src/ams/ams_base_cldc/reference/classes/com/sun/midp/main/CldcMIDletLoader.java:70: cannot resolve symbol
symbol : method initCause (java.lang.ClassNotFoundException)
location: class java.lang.NoClassDefFoundError
if (!MIDlet.class.isAssignableFrom(midletClass)) {
^
Fatal Error: Unable to locate method initCause
make[1]: *** [/home/fi9/j2me/phoneme_feature/midp/classes.zip] Error 1
make[1]: Leaving directory `/home/fi9/j2me/phoneme_feature/midp/build/linux_fb_gcc'
make: *** [build_classes] Error 2
make: Leaving directory `/home/fi9/j2me/phoneme_feature/midp/build/linux_fb_gcc'
2) gcc相关
phoneme没有考虑到交叉编译时gcc之类是有个前缀的，像：arm-linux-
因此，如果你的编译器是带前缀的必要修改以下文件：
a) phoneme_feature/pcsl/makefiles/share/gcc.gmk 修改46~47行
b) phoneme_feature/cldc/build/share/jvm.make 修改1482~1486行，并在1462行添加一行：FORCE_GCC=g++，如：
ifeq ($(IsTarget), true)
gcc_arch = $(arch)
else
gcc_arch = $(host_arch)
FORCE_GCC=g++
endif
c) phoneme_feature/midp/build/common/makefiles/gcc.gmk 修改以下几行：91, 92, 95, 104, 107, 115
如果出现类似以下的错误就是由于没做着b)这个修改：
... _MergedSrc001.cpp
{standard input}: Assembler messages:
{standard input}:6917: Error: bad instruction `int $03'
{standard input}:7803: Error: bad instruction `int $03'
{standard input}:7848: Error: bad instruction `int $03'
{standard input}:8554: Error: bad instruction `int $03'
{standard input}:8895: Error: bad instruction `int $03'
{standard input}:8996: Error: bad instruction `int $03'
{standard input}:9268: Error: bad instruction `int $03'
make[1]: *** [_MergedSrc001.o] 错误 1
make[1]: Leaving directory `/home/fi9/j2me/phoneme_feature/cldc/linux_arm/loopgen/app'
make: *** [_loopgen] 错误 2
make: Leaving directory `/home/fi9/j2me/phoneme_feature/cldc/build/linux_arm'
3) 其它
这里我只是修改了网络使用通用的BSD API实现而不是用QT库，以减少依赖性
phoneme_feature/pcsl/makefiles/top.gmk 修改82行，bsd/qte改为bsd/generic
5，可能出现的问题
1) 出现类似以下情况的一定是由于gcc的环境变量设置不对，参考上面4.2的gcc相关说明
make[2]: Entering directory `/home/fi9/j2me/phoneme_feature/pcsl/print/stdout'
/bin/sh: /opt/EmbedSky/crosstools_3.4.1_softfloat/arm-linux/gcc-3.4.1-glibc-2.3.3/bin/arm_920t_le-gcc: No such file or directory
make[2]: *** [/home/fi9/j2me/phoneme_feature/build_output/pcsl/linux_arm/obj/pcsl_print.o] Error 127
make[2]: Leaving directory `/home/fi9/j2me/phoneme_feature/pcsl/print/stdout'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/fi9/j2me/phoneme_feature/pcsl/print'
make: *** [all] Error 2
make: Leaving directory `/home/fi9/j2me/phoneme_feature/pcsl'
6，测试。
1)测试cldc。
A) copy phoneme_feature/cldc/linux_arm/dist/bin/cldc_vm 到目标主机上
B) 测试代码：
/* filename: test.java */
public class test {
public static void main(String[] args) {
System.out.println("Hello Java ME\n");
}
}
C) 要开发机上编译
javac test.java
D) copy test.class 到目标机上
E) 测试：cldc_vm test
2)测试midp
A) 分别copy phoneme_feature/midp目录下的appdb、bin和lib三目录到目标主机上
B) 运行bin/arm目录下的./autotest
7，移植。
1）屏幕宽高的设置。
修改文件：
phoneme_feature/midp/src/configuration/configuration_xml/linux_fb/constants.xml
相关的HIGHT和WIDTH
2）键盘鼠标等输入和输出。
A）fb对就的文件：phoneme_feature/midp/src/highlevelui/fb_port/fb/native/fb_port.c
修改initFrameBuffer和initKeyboard中设备的名称和初始化过程。
B）directfb：phoneme_feature/midp/src/highlevelui/fb_port/directfb/native/directfb_port.c
暂时还不清楚为什么getKeyboardFd和getMouseFd都是返回-1，
可能就造成directfb下取不到输入，具体看：
phoneme_feature/midp/src/events/mastermode_port/linux_fb/native/mastermode_check_signal.c中的函数checkForSocketPointerAndKeyboardSignal
要知下来的发展，请多多关注留意。
首次玩不太熟，有错望指出，也请牛人多指教。

=================
修正了一些错误并修改了脚本以大家更好使用 2009-03-17
=================
1，添加以下一行，并加上出错的现象：
sed -i -e "/gcc_arch = \$(host_arch)/iFORCE_GCC=g++" phoneme_feature/cldc/build/share/jvm.make
2，修改BUG。把修改ar的向前移，不然会arm-linux-gcc的会再次被匹配上并被修改为：arm-linux-arm-linux-gcc。
modified by fi9 in cn.gd.sz 2009-04-07
==================
久不动，最近把directfb + gtk移植到s3c2440，今晚也成功把midp运行了起来，不过是基于fb，下来把其再移到directfb下，然后再完善完善。
添加以下：
1，添加测试的步骤。
modified by fi9 in cn.gd.sz 2009-06-09
==================
1，添加对扩展支持的设置，如：JSRs，DirectFB，JPEG等
2，添加移植的一些心得。
