未编译MPI的Geant4输入

Question

我正在尝试使用MPI (G4MPI)在多核中编译一个Geant4输入。但是make命令会产生以下错误：

/usr/bin/ld: CMakeFiles/exMPI01.dir/exMPI01.cc.o: undefined reference to symbol '_ZNSt8ios_base4InitD1Ev@@GLIBCXX_3.4'
/usr/lib/x86_64-linux-gnu/libstdc++.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

尽管我可以在没有MPI的情况下编译输入

我的cmakelist文件是：

# - CmakeLists.txt for building an application

#----------------------------------------------------------------------------
# Setup the project
cmake_minimum_required(VERSION 2.6 FATAL_ERROR)
project(exMPI01)

#----------------------------------------------------------------------------
# check MPI package...
find_package(MPI REQUIRED)

# modify these variables if needed
#set(CMAKE_CXX_COMPILER mpicxx)
#set(CMAKE_CXX_COMPILER mpiicpc)

#set(CMAKE_CXX_INCLUDE_PATH )

#------------------------------------------------------------------------------
# Find Geant4 package, activating all available UI and Vis drivers by default
# You can set WITH_GEANT4_UIVIS to OFF via the command line or ccmake/cmake-gui
# to build a batch mode only executable
option(WITH_GEANT4_UIVIS "Build example with Geant4 UI and Vis drivers" ON)
if(WITH_GEANT4_UIVIS)
  find_package(Geant4 REQUIRED ui_all vis_all)
else()
  find_package(Geant4 REQUIRED)
endif()


find_package(G4mpi REQUIRED)

#----------------------------------------------------------------------------
# Setup Geant4 include directories and compile definitions
#
include(${Geant4_USE_FILE})

#----------------------------------------------------------------------------
# Locate sources and headers for this project
#
include_directories(${PROJECT_SOURCE_DIR}/include)
file(GLOB sources ${PROJECT_SOURCE_DIR}/src/*.cc)
file(GLOB headers ${PROJECT_SOURCE_DIR}/include/*.hh)

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include
                  ${Geant4_INCLUDE_DIR}
                  ${G4mpi_INCLUDE_DIR})

#----------------------------------------------------------------------------
# Add the executable, and link it to the Geant4 libraries
#
add_executable(exMPI01 exMPI01.cc ${sources} ${headers})
target_link_libraries(exMPI01 ${G4mpi_LIBRARIES} ${Geant4_LIBRARIES})

#----------------------------------------------------------------------------
# Copy all scripts to the build directory, i.e. the directory in which we
# build exMPI01. This is so that we can run the executable directly because it
# relies on these scripts being in the current working directory.
#
set(exMPI01_SCRIPTS
    run.mac
    v.mac
  )

foreach(_script ${exMPI01_SCRIPTS})
  configure_file(
    ${PROJECT_SOURCE_DIR}/${_script}
    ${PROJECT_BINARY_DIR}/${_script}
    COPYONLY
    )
endforeach()

#----------------------------------------------------------------------------
# Install the executable to 'bin' directory under CMAKE_INSTALL_PREFIX
#
install(TARGETS exMPI01 RUNTIME DESTINATION bin)

我曾尝试在命令行末尾使用-lstdc++，但不起作用

任何建议都会有很大帮助。

Answer 1

这种情况的一种解决方案是更新CMake中的target_link_libraries，以便手动链接到libstdc++.so库。此外，您还可以更新CMAKE_EXE_LINKER_FLAGS变量，如下所示：

target_link_libraries(exMPI01 ${G4mpi_LIBRARIES} ${Geant4_LIBRARIES} stdc++)
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -stdlib=libc++ -lc++abi")
