1、安装libpng-1.2.37，执行make错误信息，在安装目录下没有创建libpng

[root@localhost libpng-1.2.31]# make
make all-am

make[1]: *** [libpng12.la] Error 1

解决办法：cd zlib-1.2.3 //进入zlib目录
make clean
CFLAGS="-O3 -fPIC" ./configure //使用64位元的方法进行编译
make
make install
2、
（1）安装qvfb2-2.0，出现checking for X… configure: error: Can’t find X includes. Please check your installation and add the correct paths!
解决办法：安装qt3-dev-tools-embedded ， libqt3-headers and libqt3-mt-dev
sudo apt-get install qt3-dev-tools-embedded
sudo apt-get install libqt3-headers libqt3-mt-dev
（2）checking for Qt… configure: error: Qt (>= Qt 3.0.3) (headers and libraries) not found. Please check your installation!
解决办法：
sudo vim /etc/apt/sources.list 添加包含libqt3的库，
deb http://cz.archive.ubuntu.com/ubuntu precise main
添加完后
sudo apt-get update 更新库
这时
安装 sudo apt-get install libqt3-mt 库，提示依赖库没有被包含
sudo apt-get -f install 包含依赖的库
在
sudo apt-get install libqt3-mt
sudo apt-get install libqt3-mt-dev
安装完毕
（3）make qvfb2-2.0出现/usr/share/qt3/include/qpointarray.h:59: instantiated from here
/usr/share/qt3/include/qmemarray.h:62: warning: conversion to ‘int’ from ‘long unsigned int’ may alter its value
make[2]: *** [qvfbview.o] Error 1
make[2]: Leaving directory /home/yun/miniGUISour/qvfb2-2.0/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory/home/yun/miniGUISour/qvfb2-2.0’
make: *** [all] Error 2
解决办法：修改 vim qvfb2-2.0/src/qvfbview.cpp第452行
把 if ( (int)data == 1 )
qFatal( “Cannot attach to shared memory” );
改为
if ( (long)data == 1 )
qFatal( “Cannot attach to shared memory” );
3、当所有都安装完成后，在mg-samples-3.0.12/src# ./helloworld出现
start-qvfb :/usr/local/bin/gvfb pcxvfb 22164 XVFB-for-MiniGUI-3.0-(Gtk-Version) 800x600-16bpp
execlp error!!
execl: No such file or directory
NEWGAL>PCXVFB: Wait too long for CLIENT.
NEWGAL: Does not find matched engine: pc_xvfb.
KERNEL>InitGUI: Can not get graphics engine information!
解决办法：vim /usr/local/etc/MiniGUI.cfg ，
其中一句话修改成exec_file = /usr/local/bin/qvfb2
3、topeet@ubuntu:/home/yun/miniGUISour/mg-samples-3.0.12/src$ ./helloworld
问题：
./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=/home/yun/minigui/lib_x86/lib:$LD_LIBRARY_PATH
