Question

在macOS Sierra 10.12.3上运行使用英特尔Fortran编译器（15.0.3）和英特尔MKL编译的Fortran代码时遇到以下问题：

dyld: Library not loaded: libmkl_intel_lp64.dylib
  Referenced from: /Users/username/tst_ddot/bin/./tst_ddot
  Reason: image not found
Command terminated by signal 6

编译代码我使用cmake（3.7.2）并运行代码make（GNU 3.81，为i386-apple-darwin11.3.0构建）。

源代码：

  PROGRAM tst_xdot

  USE OMP_LIB

  IMPLICIT NONE

  integer, parameter :: N = 10
  integer :: err
  real, allocatable  :: a(:), b(:)
  real :: c1, c2
  real :: t0, t1, time

  real, external :: sdot


  allocate(a(N), b(N), stat=err)

  a = [1,2,3,4,5,6,7,8,9,10]
  b = [10,9,8,7,6,5,4,3,2,1]

  c1 = 0.0d+0
  c2 = 0.0d+0

  print *, "a:", a
  print *, "b:", b

  c1 = dot_product(a, b)

  t0   = omp_get_wtime()
  c2   = sdot(N, a, 1, b, 1)
  t1   = omp_get_wtime()
  time = t1-t0

  print *, "c1:",   c1
  print *, "c2:",   c2
  print *, "time:", time

  deallocate(a, b, stat=err)

  END PROGRAM tst_xdot

CMakeLists.txt档案：

# Minimum cmake version
cmake_minimum_required(VERSION 2.8.5)

# Project name
project(tst_ddot Fortran)

# set binary directory
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ../bin)

# Toolchain selection, possible arguments: Intel
set(Toolchain Intel)

# Intel compilers
if (${Toolchain} MATCHES Intel)
  set(CMAKE_Fortran_FLAGS "-O3 ${CMAKE_Fortran_FLAGS}")
endif (${Toolchain} MATCHES Intel)

# Enable MKL library
include_directories($ENV{MKLROOT}/include)
link_directories($ENV{MKLROOT}/lib)

# Enable OpenMP
find_package(OpenMP)
if (OPENMP_FOUND)
  set(CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} ${OpenMP_Fortran_FLAGS}")
endif()

# Source code files
set(SRC tst_ddot.f90)

# Main executable
add_executable(${PROJECT_NAME} ${SRC})

target_link_libraries(${PROJECT_NAME} ${LIBS} mkl_intel_lp64 mkl_intel_thread mkl_core pthread m)

只有在使用make文件运行代码时才会出现问题：

make run

制作文件来控制程序执行：

CODE = tst_ddot

run:
    ./$(CODE)

如果我直接从命令行运行代码：

./tst_ddot

程序正常执行。

使用更新版本的GNU make（GNU Make 4.2.1，为x86_64-apple-darwin16.4.0构建）可以解决这个问题。如果是MacPorts，它将被称为gmake并默认安装到/opt/local/bin/gmake。因此，运行代码的正确命令应为：

gmake run

无法加载动态库（dyld：未加载库：libmkl_intel_lp64.dylib）
