Qt4.8.6移植到hi3559（三）

1.在hi3559上，修改profile文件

vi /etc/profile

# /etc/profile: system-wide .profile file for the Bourne shells
#
#

set_path_before()
{
[ -d $1 ] && PATH="$1:$PATH"
}

export QT_INSTALL_PATH=/usr/local/Qt4.8.6
export QT_QWS_FONTDIR=${QT_INSTALL_PATH}/lib/fonts
export QT_PLUGIN_PATH=${QT_INSTALL_PATH}/lib/plugins
export QT_QWS_DISPLAY=linuxFB:/dev/fb0

PATH="/usr/bin:/usr/sbin:/bin:/sbin:${QT_INSTALL_PATH}"
set_path_before /usr/local/sbin
set_path_before /usr/local/bin

LD_LIBRARY_PATH="/usr/local/lib:/usr/lib:${QT_INSTALL_PATH}/lib:${LD_LIBRARY_PATH}"

export PATH
export LD_LIBRARY_PATH

2.copyQt库和编译好的应用程序；从虚拟机ubuntu将Qt库copy到对应目录，我这里已经已通过nfs，挂载到/opt

~ # mount
/dev/root on / type ext4 (rw,relatime,data=ordered)
proc on /proc type proc (rw,nosuid,nodev,relatime)
sysfs on /sys type sysfs (rw,nosuid,nodev,relatime)
tmpfs on /dev type tmpfs (rw,relatime)
devpts on /dev/pts type devpts (rw,relatime,mode=600,ptmxmode=000)
172.16.10.3:/home/chad/share_nfs on /opt type nfs (rw,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,hard,nolock,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=172.16.10.3,mountvers=3,mountproto=tcp,local_lock=all,addr=172.16.10.3)

cp -rv /opt/Qt4.8.6/ /usr/local/

cp -v /opt//test3559 ~/

3.加载 profile 或者重启

source /etc/profile

4. 执行test3559

chmod 777 test3599

./test3559

报这个错误:

~ # ./test3559
./test3559: line 2: syntax error: unexpected ")"
./test3559: line 1: ELF: not found~

5.在ubuntu中查看test3559状态

5.1 file ./build-test3559-hi3559_desk-Debug/test3559
./build-test3559-hi3559_desk-Debug/test3559: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/l, for GNU/Linux 2.6.32, BuildID[sha1]=7a1c4e7b8d85162c58bc0de69845e15f40834ffc, not stripped

可以看到系统架构不对，内核版本也不对！

5.2直接查看makefile 情况:

~/build-test3559-hi3559_desk-Release$ vi Makefile

增加

尴尬了，hi3559的工具链没有传过来！

5.3 查询QCROSS_HI3559

原来是配置hi3559qt的时候，编译器没有传过来！

可能和？=应该关系，也许：=或者=，可以赋值传过来，准备先强制原值来实现，重新编译Qt,参照第一篇！

5.4 修改后重新编译Qt4.8.6，再编译test3559，可以看到

查看编译后的文件：

可以看到已经编译成arm版本的了! ^.^

6.将更新后的 /usr/local/Qt4.8.4 更新到hi3559开发板，test3559也更新

执行情况如下：

 ~ # ./test3559

[15:53:$s]: QScreenLinuxFb::connect: No such file or directory

说明已经可以在hi3559上运行了，另外需要hi3559将fb0打开！将在下一篇中更新~
