目标机器：银河麒麟/arm64，所用交叉编译器为：aarch64-linux-gnu-g++
./configure -opensource -confirm-license -prefix /opt/arm_qt4.8.6 -xplatform qws/linux-aarch64-gnu-g++ -shared -no-qt3support -no-phonon -no-phonon-backend -qt-zlib -no-gif -no-libtiff -no-qvfb -qt-libjpeg -no-nis -no-opengl -no-cups -no-webkit -no-glib -no-dbus -no-rpath -no-mmx -no-3dnow -no-sse -no-sse2 -no-sse3 -no-ssse3 -no-sse4.1 -no-sse4.2 -no-avx -no-neon -no-audio-backend -no-svg -no-javascript-jit -no-script -no-scripttools -no-multimedia -no-openssl -nomake tools -nomake examples -nomake demos -DQT_ARCH_ARM
_在mkspecs/qws/linux-aarch64-gnu-g++/中的qmake.conf也已经修改完毕。
在make时出错如下图：

qmake.conf内容如下：
#

qmake configuration for building with arm-linux-g++

#

include(../../common/linux.conf)
include(../../common/gcc-base-unix.conf)
include(../../common/g++-unix.conf)
include(../../common/qws.conf)

modifications to g++.conf

QMAKE_CC = aarch64-linux-gnu-gcc
QMAKE_CXX = aarch64-linux-gnu-g++
QMAKE_LINK = aarch64-linux-gnu-g++
QMAKE_LINK_SHLIB = aarch64-linux-gnu-g++

modifications to linux.conf

QMAKE_AR = aarch64-linux-gnu-ar cqs
QMAKE_OBJCOPY = aarch64-linux-gnu-objcopy
QMAKE_STRIP = aarch64-linux-gnu-strip

load(qt_config)

看看是不是交叉编译工具链不对啊 是不是指定的交叉工具链

宿主机和目标机的指定好像没有呢 。

你这个需要制定目标机的 库文件和头文件 类似 export LIBARY_PATH 这种东西 和 依赖关系
