我正在尝试为熊猫板（OMAP4、4430）编译 Qt 嵌入式。我为 armv7 安装了这个交叉编译器：
sudo apt-get install g++-4.6-arm-linux-gnueabihf
我下载了最后一个 qt-embedded 源并将它们解压缩到文件夹中：
/opt/qt-everywhere-opensource-src-4.6.4
我复制了配置文件：
cp -r mkspecs/qws/linux-arm-gnueabi-g++ mkspecs/qws/linux-arm-gnueabihf-g++
我修改了 mkspecs/qws/linux-arm-gnueabihf-g++/qmake.conf 如下：
include(../../common/g++.conf)
include(../../common/linux.conf)
include(../../common/qws.conf)
#Compiler Flags to take advantage of the ARM architecture
#N.B.:I also tried to uncomment the two following instructions with no success
QMAKE_CFLAGS = -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp
QMAKE_CXXFLAGS = -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp
# modifications to g++.conf
QMAKE_CC = arm-linux-gnueabihf-gcc-4.6
QMAKE_CXX = arm-linux-gnueabihf-g++-4.6
QMAKE_LINK = arm-linux-gnueabihf-g++-4.6
QMAKE_LINK_SHLIB = arm-linux-gnueabihf-g++-4.6
# modifications to linux.conf
QMAKE_AR = arm-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY = arm-linux-gnueabihf-objcopy
QMAKE_STRIP = arm-linux-gnueabihf-strip
load(qt_config)
我运行了配置：
./configure -embedded arm -little-endian -no-qt3support -nomake examples -nomake demos -opensource -confirm-license -xplatform qws/linux-arm-gnueabihf-g++
但是，使用 make 命令编译当然会失败：

怎么了？
