Question

我正在为我的嵌入式电路板编写带有声子和声子后端的Qt。我输入：

./configure -embedded arm -xplatform qws/linux-arm-g++ -qt-mouse-tslib -L/home/user/ev-sdk/rootfs/arm-a8-fs/usr/lib -L/home/user/Desktop/qt-everywhere-opensource-src-4.8.1/lib -I/home/user/ev-sdk/rootfs/arm-a8-fs/usr/include -I/home/user/ev-sdk/rootfs/arm-a8-fs/usr/include/freetype2/freetype/config -prefix /opt/qt_eng -little-endian -no-gif -no-libtiff -no-libmng -no-openssl -no-opengl -no-mmx -no-3dnow -no-sse -no-sse2 -no-largefile -no-sm -svg -v -no-feature-cursor -fast -opensource -release -no-multimedia -no-cups -no-nis  -no-exceptions -nomake examples -nomake demos -no-sql-sqlite -no-g++-exceptions -phonon -phonon-backend -DQT_NO_QWS_CURSOR -DQT_THREAD_SUPPORT

/home/user/Desktop/qt-everywhere-opensource-src-4.8.1/mkspecs/qws/linux-arm-g ++中的qmake.conf：

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


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

QMAKE_CFLAGS_RELEASE     = -O3 -march=armv7-a -mtune=cortex-a8
-mfpu=neon -mfloat-abi=softfp

DEFINES +=

# modifications to g++.conf
QMAKE_CC                = sb2 -t imx53 gcc
QMAKE_CXX               = sb2 -t imx53 g++
QMAKE_LINK              = sb2 -t imx53 g++
QMAKE_LINK_SHLIB        = sb2 -t imx53 g++

# modifications to linux.conf
QMAKE_AR                = sb2 -t imx53 ar cqs
QMAKE_OBJCOPY           = sb2 -t imx53 objcopy
QMAKE_STRIP             = sb2 -t imx53 strip

load(qt_config)

如果从选项中删除-phonon -phonon-backend，则编译成功。如果我放-phonon -phonon-backend 我有这个错误：

 Turn on verbose messaging (-v) to ./configure to see the final report.
 If you believe this message is in error you may use the continue
 switch (-continue) to ./configure to continue.

我在最后两天失去了解为何给出错误。

有人可以帮助我吗？

Answer 1

Debian / linux可以使用：

   $ sudo apt-get install libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev

该命令可以在运行./configure

之前运行

Answer 2

QMAKE_LIBDIR           += -L$${ROOTFS_DIR}/usr/lib
QMAKE_CFLAGS           += -I$${ROOTFS_DIR}/usr/include/glib-2.0
QMAKE_CFLAGS           += -I$${ROOTFS_DIR}/usr/lib/glib-2.0/include
QMAKE_LIBS             += -lgthread-2.0 -lglib-2.0 -v

我交叉编译时配置Qt库4.8.1错误
