QT 5.9.7移植到ARM上,运行example程序段错误

tommyzp

1.QT 交叉编译器是gcc-linaro-4.9.4-2017.01-i686_arm-linux-gnueabihf

2.QT源码配置如下：
#!/bin/sh
./configure \
    -v \
-prefix /home/sata2/tommy500/qt-arm597-49 \
-release \
-make libs \
-xplatform linux-arm-gnueabi-g++ \
-optimized-qmake \
-pch \
-sql-sqlite \
-qt-libjpeg \
-qt-libpng \
-qt-zlib \
-tslib \
-no-opengl \
-no-sse2 \
-no-openssl \
-no-cups \
-no-glib \
-no-iconv -no-pkg-config \
-nomake examples -nomake tools \
-I/home/sata2/tommy500/tslib/include \
-L/home/sata2/tommy500/tslib/lib


3.tslib和qt库移植到ARM上设置的环境变量如下：
export TSLIB_ROOT=/system/tslib

export QT_ROOT=/system/qt-arm597

export TSLIB_TSDEVICE=/dev/input/event0

export QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/event0:rotate=180:invertx and inverty

export TSLIB_TSEVENTTYPE=input

export TSLIB_CONFFILE=/system/tslib/etc/ts.conf

export TSLIB_PLUGINDIR=/system/tslib/lib/ts

export TSLIB_CONSOLEDEVICE=none

export TSLIB_FBDEVICE=/dev/graphics/fb0

export QT_QPA_EVDEV_MOUSE_PARAMETERS=/dev/input/event0

export QT_QPA_FB_TSLIB=1

export LD_LIBRARY_PATH=/system/lib:/lib:/system/arm49lib/usr/lib:$QT_ROOT/lib:$TSLIB_ROOT/lib:$TSLIB_ROOT/

export QT_QPA_PLATFORM_PLUGIN_PATH=$QT_ROOT/plugins

export QT_QPA_PLATFORM=linuxfb:tty=/dev/graphics/fb0

export QT_QPA_FONTDIR=$QT_ROOT/fonts

export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event0

export QT_QPA_FB_HIDECURSOR=1


4.运行examples\gui\analogclock的demo可在正常显示时钟。

5.运行examples\widgets\widgets\calculator，报段错误，使用gdb调试堆栈如下：
