用QT和cmake为uCLinux编译musescore

Question

我已经尝试了几种方法，但在尝试为blackfin创建cmake时仍然出现以下错误：

CMake Error at CMakeLists.txt:116 (message):

  Fatal error: QT (version >= 4.5.0) required.  Cmake tries to detect QT4 by

  searching for 'qmake' in your PATH.If you have QT4 installed, make sure

  qmake is found in your PATH.  If you compiled QT4 yourself make sure your

  new qmake ist found _first_ in your PATH.

我正在尝试编译Musescore0.9.5的源代码，以使其与uClinux选项中现有的QT版本兼容

我所做的是用QT编译uClinux内核，这样我就可以有合适的嵌入式QT了。

然后我修改了musescore的Makefile，用uclinux编译器编译。我尝试了不同的方法，所以我在这里展示了最新的试验：

bfin:

        mkdir build;

        mkdir install;                               \

        cd build;

        cmake -DCMAKE_TOOLCHAIN_FILE=bfin.cmake -DCMAKE_VERBOSE_MAKEFILE=TRUE -\

DQT_QMAKE_EXECUTABLE=/home/william/Development_new/Music_Recognition/code/uCLin\

ux/rev2011R1/uclinux-dist/lib/qt-embedded/build-qt-embedded-linux-opensource-sr\

c-4.5.1/bin         -libdir=/home/william/Development_new/Music_Recognition/cod\

e/uCLinux/rev2011R1/uclinux-dist/lib/qt-embedded/build-qt-embedded-linux-openso\

urce-src-4.5.1/lib    \
                -DCMAKE_INSTALL_PREFIX="${PREFIX}" \
                mscore;

在CMakeLists.txt中，我添加了：

link_directories(/home/william/Development_new/Music_Recognition/code/uCLinux/r\

ev2011R1/uclinux-dist/lib/qt-embedded/build-qt-embedded-linux-opensource-src-4.\

5.1/bin)



SET(CMAKE_MODULE_PATH /home/william/Development_new/Music_Recognition/code/uCLi\

nux/rev2011R1/uclinux-dist/lib/qt-embedded/build-qt-embedded-linux-opensource-s\

rc-4.5.1/bin)



SET(CMAKE_PREFIX_PATH /home/william/Development_new/Music_Recognition/code/uCLi\

SET(QT_QMAKE_EXECUTABLE /home/william/Development_new/Music_Recognition/code/uC\

Linux/rev2011R1/uclinux-dist/lib/qt-embedded/build-qt-embedded-linux-opensource\

-src-4.5.1/bin)

我的bfin.cmake是这样的：

# this one is important                                                     

SET(CMAKE_SYSTEM_NAME Linux)
#this one not so much                                                       

SET(CMAKE_SYSTEM_VERSION 1)


#                                                                           

SET (BFIN "/opt/uClinux/bfin-uclinux")


# specify the cross compiler                                                
SET(CMAKE_C_COMPILER    ${BFIN}/bin/bfin-uclinux-gcc)

SET(CMAKE_CXX_COMPILER   ${BFIN}/bin/bfin-uclinux-g++)
SET(CMAKE_LINKER        ${BFIN}/bin/bfin-uclinux-ld)


#/opt/uClinux/bfin-uclinux/bfin-uclinux/runtime/usr/lib                     

LINK_DIRECTORIES("${BFIN}/usr/lib")



SET(CMAKE_FIND_ROOT_PATH

  /opt/uClinux/bfin-uclinux/bfin-uclinux

  /opt/uClinux/bfin-linux-uclibc

  /opt/uClinux/bfin-linux-uclibc/bfin-linux-uclibc/runtime)


# search for programs in the build host directories                         

SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
# for libraries and headers in the target directories                       

SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)

SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

先感谢你的帮助，

你需要在你的$PATH中放入qmake。如果您更喜欢使用QT_QMAKE_EXECUTABLE，那么它必须指向实际的qmake二进制文件，而不是目录。

也就是说，MuseScore 0.9.5是MuseScore的一个非常非常老的版本，当前版本是1.1，1.2即将发布。有关MuseScore的更多信息，请查看http://musescore.org，请毫不犹豫地通过freenode.net上的#musescore或http://musescore.org/mailing-list上的开发人员邮件列表联系开发人员
