Question

我对SWIG非常陌生（事实上，这是我的第一个使用它的“项目”），并且遇到了一个我不太了解的错误。我一直在尝试像这样一小段C代码使用SWIG：

src / fft.c

#include "fft.h"
void separate(double complex *a, int n)
{
  ...
}

void fft2(double complex *x, int n)
{
  ...
}

src / fft.h

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <complex.h>
#include <math.h>
void separate(double complex *a, int n);
void fft2(double complex *x, int n);

这是我的Swig接口文件：

src / swig / fft.i

%module fft
%{
#include "fft.h"
%}
%include "fft.h"

当我使用CMake作为构建系统时，这里是CMakeLists.txt文件

src / CMakeLists.txt

add_library(
    fft SHARED
    fft.c
)

set_target_properties(fft PROPERTIES VERSION ${PROJECT_VERSION})
set_target_properties(fft PROPERTIES PUBLIC_HEADER "fft.h")

add_subdirectory(swig)

src / swig / CMakeLists.txt

find_package(SWIG REQUIRED)
include(${SWIG_USE_FILE})

add_subdirectory(python)

src / swig / python / CMakeLists.txt

find_package(PythonLibs REQUIRED)
include_directories(${PYTHON_INCLUDE_PATH})

set(CMAKE_SWIG_FLAGS "")
set_source_files_properties(../fft.i PROPERTIES CPLUSPLUS ON)
include_directories(../..)

swig_add_library(fft LANGUAGE python SOURCES ../fft.i)
swig_link_libraries(fft ${PROJECT_NAME} ${PYTHON_LIBRARIES})

这是cmake ..目录中make和build的输出：

make

如您所见，我在macOS（Mojave）上，C中的共享库可以编译，但SWIG似乎无法与标头中的函数声明相处。我尝试删除了complex（仅使用double个数字），它似乎可以正常工作，所以我猜测是无法找到某种原因的complex.h文件...

任何帮助将不胜感激！

谢谢！
