Question

我有一个简单的cmake项目，我无法在OS X 10.8.4上编译。 cmake / make过程在Linux上运行良好但在OS X上我收到此错误：

Linking CXX static library libImageFilter.a
ar: no archive members specified
...
make[2]: *** [lib/libImageFilter.a] Error 1
make[1]: *** [lib/CMakeFiles/ImageFilter.dir/all] Error 2
make: *** [all] Error 2

我在两个平台上都使用Eclipse CDT4 Generator Unix MakeFile。这似乎与两个系统上的ar之间的区别有关。但是，我在谷歌找不到太多帮助我排除故障。

以下是您的更多信息

的src / CMakeList.txt

make_minimum_required(VERSION 2.8)
project(itkNormals)
FIND_PACKAGE (ITK REQUIRED)
IF( ITK_FOUND )
  include( ${ITK_USE_FILE} )
ENDIF( ITK_FOUND )
add_subdirectory(test)
add_subdirectory(lib)

的src / LIB / CMakeList.txt

add_library(DotImageFilter itkDotImageFilter.h)
SET_TARGET_PROPERTIES(DotImageFilter PROPERTIES LINKER_LANGUAGE CXX)
target_link_libraries(DotImageFilter ${ITK_LIBRARIES})

add_library(ImageFilter itkImageFilter.hxx)
SET_TARGET_PROPERTIES(ImageFilter PROPERTIES LINKER_LANGUAGE CXX)
target_link_libraries(ImageFilter ${ITK_LIBRARIES})

的src /测试/的CMakeLists.txt：

include_directories(${PROJECT_SOURCE_DIR}/lib)

add_executable(itkNormalsMain itkNormals.cxx)
TARGET_LINK_LIBRARIES(itkNormalsMain ${ITK_LIBRARIES})
TARGET_LINK_LIBRARIES(itkNormalsMain ImageFilter)
TARGET_LINK_LIBRARIES(itkNormalsMain DotImageFilter)

add_executable(dotTestMain dotTester.cxx)
TARGET_LINK_LIBRARIES(dotTestMain ${ITK_LIBRARIES})
TARGET_LINK_LIBRARIES(dotTestMain ImageFilter)
TARGET_LINK_LIBRARIES(dotTestMain DotImageFilter)

add_executable(IST ImageSourceTest.cxx)
TARGET_LINK_LIBRARIES(IST ${ITK_LIBRARIES})
TARGET_LINK_LIBRARIES(IST ImageFilter)

您无法从一个头文件创建库：

add_library(ImageFilter itkImageFilter.hxx)
SET_TARGET_PROPERTIES(ImageFilter PROPERTIES LINKER_LANGUAGE CXX)
target_link_libraries(ImageFilter ${ITK_LIBRARIES})

这就是你明确设置LINKER_LANGUAGE的原因 - 有没有来链接，而cmake很困惑。

所以include_directories就足够了：

include_directories(${PROJECT_SOURCE_DIR}/lib)

<强>顺便说一句：

如果您指定ITK_FOUND：

，则无需检查REQUIRED

FIND_PACKAGE (ITK REQUIRED)
IF( ITK_FOUND )
  include( ${ITK_USE_FILE} )
ENDIF( ITK_FOUND )

来自documentation：

The REQUIRED option stops processing with an error message if the package cannot be found.

PROJECT_SOURCE_DIR不一定等于itkNormals_SOURCE_DIR（您可以使用其他项目中的此文件）：

include_directories(${PROJECT_SOURCE_DIR}/lib)

可以通过以下方式修复：

include_directories(${itkNormals_SOURCE_DIR}/lib)
include_directories(${CMAKE_CURRENT_LIST_DIR}/../lib)

或只是从父文件中包含：

# src/CMakeLists.txt
include_directories("./lib")

cmake os x failure ar没有特定的归档成员
