arm-linux-gcc版本 4.3.3
目录如下:
[root@localhost minigui]# ls -al 总计 6820 drwxrwxrwx 6 root root 4096 03-07 23:53 . drwxr-x--- 51 root root 4096 03-10 15:53 .. drwxrwxrwx 8 1000 1000 4096 03-10 15:53 libminigui-1.6.10 -rwxrwxrwx 1 root root 2786624 2008-03-06 libminigui-1.6.10.tar.gz -rwxrwxrwx 1 root root 607273 2008-03-06 mde-1.6.10.tar.gz drwxrwxrwx 4 1000 1000 4096 03-08 00:06 mg-samples-1.6.10 -rwxrwxrwx 1 root root 577762 2008-03-06 mg-samples-1.6.10.tar.gz drwxr-xr-x 7 1000 1000 4096 03-07 23:19 minigui-res-1.6.10 -rwxrwxrwx 1 root root 2956865 2008-03-06 minigui-res-1.6.10.tar.gz drwxr-xr-x 6 root root 4096 03-10 14:22 tmp
|
2、解压libminigui-1.6.10.tar.gz,修改configure,在其首部加入以下内容:
CC=arm-linux-gcc CPP=arm-linux-cpp LD=arm-linux-ld AR=arm-linux-ar RANLIB=arm-linux-ranlib STRIP=arm-linux-strip
|
然后执行
[root@localhost libminigui-1.6.10]# ./configure --prefix=/root/minigui/tmp/ \ > --host=arm-linux \ > --target=arm-linux [root@localhost libminigui-1.6.10]#make; make install
|
install以后就会在tmp下生成etc、lib、usr等个文件夹,为下面的准备文件
然后进入到tmp/lib文件夹下执行
[root@localhost lib]# pwd /root/minigui/tmp/lib [root@localhost lib]# ldconfig
|
3、安装minigui-res-1.6.10.tar.gz,这个简单些,解压后进去修改config.linux第11行,修改成TOPDIR=/root/minigui/tmp/ 然后make install就ok了
4、修改tmp/etc/MiniGUI.cfg这个文件,前面修改成如下几行
[system] # GAL engine and default options gal_engine=fbcon defaultmode=320x240-16bpp
# IAL engine ial_engine=console mdev=none mtype=none
[fbcon] defaultmode=320x240-16bpp
[qvfb] defaultmode=320x240-16bpp display=0
|
其中
mdev=none mtype=none由于暂时没有移植触摸屏,所以选择none,不然运行例程的时候会出现
InitGUI: Low level event initialization InitGUI failure when using /etc/MiniGUI.cfg as cfg file.
|
这样的错误,改成mdev=none mtype=none就好了
5、添加库文件到板子上去,说明一下,我板子上的文件系统是yaffs2,不是ramdisk,所以可以通过终端修改文件系统内文件的内容,就不必每次修改了都在烧写文件系统或是用uboot通过tftp传ramdisk了,方便。现在要拷贝的库一些来自刚刚编译的tmp下的文件,一些来自交叉编译工具;链本身,都是需要从pc上拷贝到板子上,我的方法是先把需要的文件拷贝到pc上nfs的共享文件夹,再把此文件夹mount到板子上,然后从终端拷贝需要的文件到板子相应的文件里!他们的对应关系是 tmp/lib下的所有文件--->板子的/usr/lib;tmp/usr/local/lib/minigui整个文件夹--->板子/usr/local/lib/minigui 别忘了把tmp/etc/MiniGUI.cfg这个文件也拷贝到板子/etc下面,库就考完了……
6、编译例程:解压mg-samples-1.6.10.tar.gz并进入修改configure.in,第30行左右修改成AC_CHECK_HEADERS(/root/minigui/tmp/include/minigui/common.h, have_libminigui=yes, foo=bar),明显是指定头文件路径的;然后修改configure,添加如下
CC=arm-linux-gcc CPP=arm-linux-cpp LD=arm-linux-ld AR=arm-linux-ar RANLIB=arm-linux-ranlib STRIP=arm-linux-strip
|
执行如下
[root@localhost mg-samples-1.6.10]# ./configure --prefix=/root/minigui/tmp/ \ > --host=arm-linux\ > --target=arm-linux
|
即可身生成Makefile等文件,修改src/Makefile,
-----198行 COMPILE = $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) \ $(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS) -lminigui -lmgext -lm -lpthread -lpng -ljpeg -------250行 CC = arm-linux-gcc -I /root/minigui/tmp/include -L /root/minigui/tmp/lib -----252 CFLAGS =-O2 -----268行 LIBOBJS = -lminigui -lmgext -lm -lpthread -lpng -ljpeg -----269行 LIBS = -lminigui -lmgext -lm -lpthread -lpng -ljpeg
今天出现了怪现象,configure以后修改src里面的Makefile,然后make,会check,然后在生成Makefile,以至配置不见了,故出现头文件找不到的情况,这个的好好细究一哈是怎么回事!!昨晚郁闷了,本来是要重新写个gui的,结果把时间花在编译上了……修改了src\Makefile后make出现的信息如下:

可以看出是头文件路径发生了变化,从上面信息可以看出又生成了src/Makefile,打开一看,刚才修改的东西不见了,所以找不到头文件!!!!!!!!!!
经过几番尝试,发现需要打开mg-samples-1.6.10顶层目录下的Makefile一次,不管是在修改src/Makefile前还是后,打开一次保存即可,无需修改,然后在make……
不明白这是为什么,难道是要重新确定两个Makefile的修改时间? |
make以后就可以在src下生成很多可执行文件,通过nfs mount到板子上,运行就可以看到helloword的界面了,嘿嘿!执行时可以会缺少一下png、JPEG的库文件,到交叉工具链的目录下拷贝到板子上的/usr/lib文件下即可,拷贝时注意用ls -al 查看文件的链接信息,cp时加上-a这个参数,以保证一摸一样!如下:
[root@localhost lib]# ls -al libpng12.so* lrwxrwxrwx 1 root root 18 03-09 14:10 libpng12.so -> libpng12.so.0.38.0 lrwxrwxrwx 1 root root 18 03-09 14:10 libpng12.so.0 -> libpng12.so.0.38.0
|
要拷贝
libpng12.so 这个库,就要连同libpng12.so.0.38.0一起拷贝,使用命令cp -a libpng12.so……
