go通过swig方式调用c++，遇到困难了，有偿求助！

[toc] # 1: 现有资料 - cpp头文件 - 一个.so库 - cpp头文件API说明文档 # 2：现在进度 - 基本完成swig接口文件，已经可以进行`swig -c++ -go -cgo -intgosize 64 ./xxx.i`进行转换 - 生成 xxx_wrap.h,xxx_wrap.cxx,xxx.go - `go build `进行编译的时候，xxx_wrap.cxx文件报错，信息如下 ```go # goama/src ama_wrap.cxx: In function ‘_gostring_ _wrap_CPPIAMDApi_GetVersion_src_339c721e06099bce()’: ama_wrap.cxx:21967:24: error: ‘CPPIAMDApi_GetVersion’ was not declared in this scope 21967 | result = (char *)CPPIAMDApi_GetVersion();; ... ama_wrap.cxx:21960:11: error: ‘CPPIAMDSpi’ in namespace ‘amd::ama’ does not name a type; did you mean ‘IAMDSpi’? 21960 | amd::ama::CPPIAMDSpi *_wrap_new_CPPIAMDSpi_src_9218e0d178690c28() { | ^~~~~~~~~~ | IAMDSpi ... 很多类似不在scope，找不见对应的class等的错误 ``` # 3：遇到的困难 1: swig 转Go的时候，带有指针的函数如何处理，目前是class放在swig交换文件中 2：cpp 的namespace如何处理，现在的问题好像是这个原因导致的 3: 或者有其他更好的思路 # 4：补充 ## 4.1 关键点 - namespace - reference - class ## 4.2 swig接口文件 ```go %module(directors="1") src %{ #include <vector> #include <stdint.h> #include <string> #include "ama_datatype.h" #include "ama_export.h" #include "ama_struct.h" #include "ama_tools.h" #include "ama.h" %} %include "ama_datatype.h" %include "ama_export.h" %include "ama_struct.h" %include "ama_tools.h" %include "ama.h" %include "std_deque.i" %include "std_pair.i" %include "std_string.i" %include "std_vector.i" %include "stdint.i" %include "typemaps.i" // %include "std_multimap.i" // %include "std_multiset.i" // %include "std_set.i" // %include "std_array.i" // %include "std_auto_ptr.i" // %include "std_complex.i" // %include "std_unordered_map.i" // %include "std_unordered_multimap.i" // %include "std_unordered_multiset.i" // %include "std_unordered_set.i" // %include "std_wstring.i" // %include "std_shared_ptr.i" %feature("director")IAMDSpi; // typemap %typemap(gotype) unsigned int "uint"; // transform c++ exception into go errors %include "exception.i" %exception { try { $action; } catch (std::runtime_error &e) { _swig_gopanic(e.what()); } } %rename(CPPIAMDApi) amd::ama::IAMDApi; %rename(CPPIAMDSpi) amd::ama::IAMDSpi; // namespace %nspace amd::ama::IAMDSpi; %nspace amd::ama::IAMDApi; %nspace amd::ama::CPPIAMDApi; %nspace amd::ama::CPPIAMDSpi; %nspace amd::ama::Tools; // // // // // %nodefaultctor amd::ama::IAMDApi; // // %nodefaultctor amd::ama::IAMDSpi; // // class CPPIAMDApi { public: %extend{ static const char* GetVersion(); static int32_t Init(const IAMDSpi* pSpi, const Cfg& cfg); static void Join(); static int32_t Release(); static void FreeMemory(void* data); static int32_t SubscribeData(int32_t subscribe_type, const SubscribeItem* item, uint32_t cnt); static int32_t SubscribeData(int32_t subscribe_type, const SubscribeCategoryItem* item, uint32_t cnt); static bool GetCodeTableList(CodeTableRecordList& list); } }; ```
