QT时钟程序报不能加载.so库

huanian LV 4

这是t113 linux下的错误提示：

# ./analogclock
./analogclock: error while loading shared libraries: libQt5Gui.so.5: cannot open shared object file: No such file or directory

此文件是存在的

# cd  /usr/local/Qt_5.12.5/lib/                         
# find ./ -name  libQt5Gui.so.5
./libQt5Gui.so.5
#

在PC端查看的analogclock的文件属性：

$ file analogclock

$ readelf -d analogclock

@huanian 两个的libc不同，可以尝试使用相同的编译器，libc库重新编译qt

@yuzukitsuru 感谢回复，我自己摸索解决了。
我用LonganSDK，参照/etc/init.d/rcS里的开机启动脚本，用下面这个指令可以正常启动QT的app

#  /etc/qtenv.sh & ./analogclock

[1] 16558
/etc/qtenv.sh: line 17: [: too many arguments
add /dev/input/event5 to Qt Application.
find qt5 installed done
xkbcommon: ERROR: failed to add default include path /usr/share/X11/xkb
Failed to create xkb context

这个xkbcommon: ERROR 报错不影响使用，就没管他
