在Kotlin中使用C函数时的SWIG错误 - 两个不同的错误

Question

我正在使用以下命令使用swig：

swig -java -includeall -package onescream.onescream compute_feature_set.i

接口文件是：

/* compute_feature_set.i */
 %module compute_feature_set
%{
/* Includes the header in the wrapper code */
#include "compute_feature_set.h"
%}

/* Parse the header file to generate wrappers */
%include "compute_feature_set.h"

我会收到以下错误：

compute_feature_set.h:17: Error: Unable to find 'stddef.h'
compute_feature_set.h:18: Error: Unable to find 'stdlib.h'

如果尝试替代swig命令列表：

swig -java compute_feature_set.i
gcc -c compute_feature_set.c compute_feature_set_wrap.c -I/Users/fas/Library/Java/JavaVirtualMachines/openjdk-18.0.1.1/Contents/Home/include -I/Users/fas/Library/Java/JavaVirtualMachines/openjdk-18.0.1.1/Contents/Home/include/darwin
gcc -shared compute_feature_set.o compute_feature_set_wrap.o -o libcompute_feature_set.so

我会收到以下错误：

Undefined symbols for architecture arm64:
  "_b_fft", referenced from:
      _compute_feature_set in compute_feature_set.o
  "_binary_expand_op", referenced from:
      _compute_feature_set in compute_feature_set.o
  "_eml_find", referenced from:
      _compute_feature_set in compute_feature_set.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我不确定该怎么办感谢。

您通常不需要-includeAll，因为您不太可能想包装Endire stddef.h和stdlib.h库函数（通常它无论如何都无法正常工作）。

使用-i＆lt; dir＆gt;在搜索路径中包含其他目录。
