我正在使用这些步骤(第二行源代码)。然而,我读/写扩展名为.h5的文件,其中的代码肯定需要这个标志:-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,标志必须放置在编译命令的末尾,如本答案所述。
由于有评论,我更新了我的问题。
所以,我修改了CMakeLists.txt,我更改的是这一部分:
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,似乎没有找到hdf5。
编辑
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
我想问题就在这里(也可以看到我联系的答案)hdf5的链接器标志不在末尾
最后该怎么说?也许我用错了set()
?
EDIT-解决方案
以下是正在运行的CMakeLists.txt:

我一起使用CGAL和HDF5。这是我的CMakeLists.txt
:中的相关部分
find_package (HDF5 QUIET COMPONENTS CXX)

include_directories (SYSTEM ${HDF5_CXX_INCLUDE_DIR})
add_library (hdf5 STATIC IMPORTED)

set (HDF5_libraries hdf5 hdf5_cpp)
add_executable (exe match.cpp)
target_link_libraries (exe ${libraries} ${HDF5_libraries})
endif (HDF5_FOUND)
在CMakeLists.txt的早期版本中,有:
find_package (CGAL)

add_definitions (${CGAL_CXX_FLAGS_INIT})
include_directories (${CGAL_INCLUDE_DIRS})
set (libraries ${libraries} ${CGAL_LIBRARY} ${CGAL_3RD_PARTY_LIBRARIES})
