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

  # 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
