基于linux下交叉编译minigui体会

 能不用minigui就不用是对的，这段时间一直在交叉编译minigui，困难是妥妥的多，几乎每一个包都有问题，现在我就记录下碰到的问题，大部分都是在网上找的解决办法，网上还是大神多啊，下载的库都是在minigui官网下的，有些问题是库的问题，低版本库有问题，高版本库自己就好了，自己也是莫名其妙。

[编译1.3.1 freetype库]
其他版本的库就编译下面这行 我碰见的错误就下面那个
./configure --host=arm-linux-gnueabihf --prefix=/home/lq/build/lq_work/minigui --with-freetype=/home/lq/build/lq_work/minigui/freetype/
 vi /home/lq/build/lq_work/minigui/freetype-2.3.9-fm20100818/builds/unix/install.mk +50 注释掉
make &&make install
编译1.3.1 freetype库需要用到
 vim config.cache

ac_cv_prog_CPP=${ac_cv_prog_CPP='/usr/local/linaro-armv7ahf-2015.11-gcc5.2/bin/arm-linux-gnueabihf-g++ -E'}
重新配置
./configure --host=arm-linux-gnueabihf --prefix=/home/lq/build/lq_work/minigui
#修改Makefile文件，以跳过编译test目录。
#去掉“all:”后的变量“tttest”
#注释掉“install:”下的第二行：“cd $(FTTESTDIR); $(MAKE) –f$(MAKEFILE) install”

在开发板上运行：
修改配置
$ vim /usr/local/minigui/etc/MiniGUI.cfg
02  # 修改如下参数
03  # GAL engine and default options
04  gal_engine=fbcon
05   
06  # IAL engine
07  ial_engine=console
08  mdev=/dev/input/mice
09  mtype=IMPS2
10   
11  # 根据实际的显示大小填
12  [fbcon]
13  defaultmode=480x272-16bpp


运行sample问题总结
（1）./helloworld: error while loading shared libraries: libminigui_ths-3.0.so.12: cannot open shared object file: No such file or directory
解决：
export LD_LIBRARY_PATH=/sdcard/ \
export LD_LIBRARY_PATH=/sdcard/lib:$LD_LIBRARY_PATH


（2）MISC: Can not locate your MiniGUI.cfg file or bad files!
KERNEL>InitGUI: Initialization of misc things failure!
解决：把libminigui-gpl-3.0.12/etc/MiniGUI.cfg复制到当前目录下[mg-samples-3.0.12/src]
（3）KERNEL>InitGUI: Count not init mouse cursor!
KERNEL>InitGUI: Init failure, please check your MiniGUI configuration or resource.
解决：
修改MiniGUI.cfg配置文件

本来还有个unknow type png的错误，在核心库添加LDCAFLAGS就好了，交叉编译好了，正式进入项目开发！！
