Question

我正在使用these步骤（第二个源代码中的第42行）。但是，我读取/写入扩展名为.h5的文件，其中代码肯定需要此标记：-lhdf5。

为了编译hdf5的函数，我会做这样的事情：

g++ -std=c++0x main.cpp -lhdf5

请注意，标志必须放在编译命令的末尾，如this answer中所述。

由于评论，我更新了我的问题。

所以，我修改了CMakeLists.txt，我改变的是这部分：

add_definitions(${CMAKE_CXX_FLAGS} "-std=c++0x")
set(CMAKE_EXE_LINKER_FLAGS "-lhdf5 -lhdf5_hl -lhdf5_cpp")

然而，当我执行make时，似乎找不到hdf5。

修改

根据Marc的建议，我得到了：

Linking CXX executable exe
/usr/bin/cmake -E cmake_link_script CMakeFiles/exe.dir/link.txt --verbose=1
/usr/bin/c++    -frounding-math -O3 -DNDEBUG  -lhdf5 -lhdf5_hl -lhdf5_cpp CMakeFiles/exe.dir/match.cpp.o  -o exe -rdynamic -L/home/samaras/code/CGAL-4.3/lib -L/usr/local/lib -lmpfr -lgmp /home/samaras/code/CGAL-4.3/lib/libCGAL.so -lboost_thread-mt -lpthread /usr/local/lib/libboost_system.so /home/samaras/code/CGAL-4.3/lib/libCGAL.so -lboost_thread-mt -lpthread /usr/local/lib/libboost_system.so -Wl,-rpath,/home/samaras/code/CGAL-4.3/lib:/usr/local/lib

这是问题，我想（看到我联系的答案）。 hdf5的链接器标志不在最后。

如何把它放在最后？也许我使用了错误的set()？

我一起使用CGAL和HDF5。这是我CMakeLists.txt的相关位：

find_package                (HDF5 QUIET COMPONENTS CXX)

if                          (HDF5_FOUND)

  include_directories       (SYSTEM ${HDF5_CXX_INCLUDE_DIR})

  add_library               (hdf5 STATIC IMPORTED)
  set_target_properties     (hdf5 PROPERTIES IMPORTED_LOCATION ${HDF5_hdf5_LIBRARY})
  add_library               (hdf5_cpp STATIC IMPORTED)
  set_target_properties     (hdf5_cpp PROPERTIES IMPORTED_LOCATION ${HDF5_hdf5_cpp_LIBRARY})
  set                       (HDF5_libraries     hdf5 hdf5_cpp)

  add_executable            (exe match.cpp)
  target_link_libraries     (exe ${libraries} ${HDF5_libraries})
endif                       (HDF5_FOUND)

在CMakeLists.txt的早些时候，有：

find_package            (CGAL)
include                 (${CGAL_USE_FILE})
add_definitions         (${CGAL_CXX_FLAGS_INIT})
include_directories     (${CGAL_INCLUDE_DIRS})
set                     (libraries ${libraries} ${CGAL_LIBRARY} ${CGAL_3RD_PARTY_LIBRARIES})
set                     (CMAKE_EXE_LINKER_FLAGS "-dynamic ${CMAKE_EXE_LINKER_FLAGS}")

无法使cgal和hdf5协同工作
