昨天我下载了Qt4 Opensource library for linux。运行后
./configure
./make
./make install
将其插入我的.bashrc文件:
PATH=/usr/local/TrollTech/Qt-4.7.3/bin:$PATH
export PATH
在此之后,我运行了cmake以便为我生成一个Makefile。的CMakeLists.txt:
project(VTKToVTFx)
cmake_minimum_required(VERSION 2.6)
find_package(VTK REQUIRED)
find_package(Qt4 REQUIRED)
include(${VTK_USE_FILE})
include(${QT_USE_FILE})
SET(VTK_TO_VTFX_FORMS main.ui)
QT4_WRAP_UI(VTK_TO_VTFX_FORMS_UIC ${VTK_TO_VTFX_FORMS})
SET(MOC_HEADERS VTKToVTFx.h)
qt4_wrap_cpp(MOC_OUTFILES ${MOC_HEADERS})
SET(CPP_SOURCES VTKToVTFx.cpp
VTKPatch.cpp
VTKFile.cpp
VTKData.cpp
VTKDataHolder.cpp
)
add_executable(VTKToVTFx ${CPP_SOURCES} ${VTK_TO_VTFX_FORMS_UIC} ${MOC_OUTFILES})
# Adds folders for Visual Studio solution explorer (and for Xcode explorer)
source_group( "Generated" FILES ${MOC_FILES_CPP} ${VTK_TO_VTFX_FORMS_UIC} ${QRC_FILES_CPP} ${MOC_OUTFILES})
INCLUDE_DIRECTORIES(${CMAKE_CURRENT_BINARY_DIR})
target_link_libraries(VTKToVTFx vtkHybrid)
target_link_libraries(VTKToVTFx QtCore4)
target_link_libraries(VTKToVTFx QtGUI4)
这个CMakeLists.txt在Windows上工作得很好,但是当我尝试在安装Ubuntu时编译输出时,会发生以下错误:
/usr/bin/ld: cannot find -lQtCore4
/usr/bin/ld: cannot find -lQtGUI4
有人能指出我的问题吗?
答案 0 :(得分:3)
在unix [like]世界中,斜杠是路径分隔符,而不是反斜杠。
\usr\local\TrollTech\Qt-4.7.3\bin
评估为usrlocalTrollTechQt-4.7.3bin
。
编辑:此外,您的CMakeLists.txt似乎有点犯规。看看http://qtnode.net/wiki/Qt4_with_cmake。而不是
target_link_libraries(VTKToVTFx QtCore4)
使用类似的东西(来源是链接的网站):
- 要添加对网络或qttest等Qt4库的支持,您需要添加包含文件和相应的库。例如,要添加对网络和qttest库的支持,您可以使用:
INCLUDE_DIRECTORIES(
${QT_INCLUDE_DIR}
${QT_QTNETWORK_INCLUDE_DIR}
${QT_QTTEST_INCLUDE_DIR}
)
TARGET_LINK_LIBRARIES(
${QT_LIBRARIES}
${QT_QTNETWORK_LIBRARIES}
${QT_QTTEST_LIBRARIES}
)
即使在4.x版本的版本中,库也已重命名并将重命名。幸运的是,不需要硬编码:)
