不能让 cgal 和 hdf5 一起工作

Question

我正在使用these 步骤（第二个源代码位置的第 42 行）。但是，我读/写扩展名为 .h5 的文件，其中代码肯定需要这个标志：-lhdf5。

为了编译 hdf5 的函数，我会这样做：

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

注意标志必须放置在编译命令的末尾，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")

但是，当我执行 make 时，似乎找不到 hdf5。

在马克的建议下，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

我认为这就是问题所在（也请参阅我链接的答案）。 hdf5 的链接器标志不在末尾。

最后怎么写？也许我用错了set()？

这是有效的 CMakeLists.txt：

# This is the CMake script for compiling a set of CGAL applications.

Answer 1

我同时使用 CGAL 和 HDF5。这是我的CMakeLists.txt 的相关内容：

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 的前面，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}")
