OS: ubuntu 12.1
gcc: 4.6.3
arm gcc: 4.5.1
QT: qt-x11-opensource-src-4.5.3
QT-embedded: qt-embedded-linux-opensource-src-4.5.3
编译qt-x11-opensource-src-4.5.3
./configure –qvfb
make
cd tools/qvfb //进入此目录，准备对它进行编译
make
sudo make install
编译过程中出现的错误:
error: ‘ppd_file_t’ does not name a type
解决方法：
打开src/gui/painting/qcups_p.h做如下修改:
#ifndef QT_NO_CUPS
#include //加入ppd头文件
QT_BEGIN_NAMESPACE
安装 arm-linux-gcc
(略)
编译qt-embedded-linux-opensource-src-4.5.3
./configure -embedded arm -qt-libpng
make
sudo make install
编译时间会很长，可以使用下面的配置来减少编译时间:
./configure -embedded arm -qt-libpng \
-release \
-shared \
-fast \
-no-largefile \
-qt-sql-sqlite \
-no-qt3support \

安装vsftpd
apt-get install vsftpd
编辑 /etc/vsftpd.conf
listen=YES
#anonymous_enable=YES
local_enable=YES
write_enable=YES
#anon_upload_enable=YES
anonymous_enable=NO #默认是允许
dirmessage_enable=YES # 允许进入文件夹
xferlog_enable=YES # 允许 ftp 日志记录允许
connect_from_port_20=YES # 允许使用20号端口作为数据传送端口
secure_chroot_dir=/var/run/vsftpd/empty

设置ftp文件夹
mkdir -p /home/ftp/upload
mkdir -p /home/ftp/download
chmod 755 /home/ftp
chmod 777 /home/ftp/upload
chmod 755 /home/ftp/download
设置ftp用户
-
增加ftp组：groupadd ftpgroup
-
编辑 /etc/vsftpd.conf:
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list
-
增加ftp用户: useradd -g ftpgroup -d /home/ftp -M upload ftpuser
-
设置ftp用户密码: passwd ftpuser
-
编辑 /etc/vsftpd.chroot_list:
ftpuser
-
重启vsftp服务: service vsftpd restart

qtopia: 2.2.0
OS: ubuntu 12.1
安装必要软件
sudo apt-get -y install x-dev libx11-dev x11proto-xext-dev libxext-dev libqt3-mt-dev uuid uuid-dev
sudo apt-get install libv4l-dev
遇到的问题
问题1
安装libv4l-dev后还是会提示缺少 linux/videodev.h
解决
原因是 3.2.0 已经移除了对 v4l1 的支持，可以在linux/目录下建立软链接：
ln -s /usr/include/lib4l1.h /usr/include/linux/videodev.h
问题2
error: ‘ptrdiff_t’ does not name a type
解决
这个错误应该是libc的版本造成的，解决的方法是在每个报错的头文件中加入
include <stddef>
问题3
undefined reference to `uuid_generate'
解决
git clone git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git 或者网络下载e2fsprogs源码包
编译e2fsprogs:
./configure --enable-elf-shlibs
sudo cp -av libuuid.so* /usr/lib
接下来正常编译qtopia，Done !
