ApiHookMocker编译报错

[xiaoyur347]

开启-Werror,-Wreturn-type，会存在编译报错：
emock/include/emock/ApiHookMocker.h:104:1: error: non-void function does not return a value in all control paths [-Werror,-Wreturn-type]
104 | }
| ^

问题原因：

template <>
inline InvocationMockBuilderGetter mockAPI<const char>(const std::string&, const char* matcher)
{
    std::string m(matcher);
    std::string returnType("void");
    std::string::size_type from = m.find('{');
    if(from != std::string::npos) {
      std::string::size_type to = m.find('}', from);
      returnType = m.substr(from + 1, to - from - 1);
      m = m.replace(from, to - from + 1, "");
    }
    from = m.find('#');
    std::string callingConv;
    if(from != std::string::npos) {
      std::string::size_type to = m.find('#', from);
      callingConv = m.substr(from + 1, to - from - 1);
      m = m.replace(from, to - from + 1, "");
    }
    else {
      from = m.find('!');
      if(from != std::string::npos) {
        callingConv = "EMOCK_API";
        m = m.erase(from, 1);
      }
    }
    RT_BRANCH(void)
    else INTERGRAL_RT_BRANCH(char)
    else INTERGRAL_RT_BRANCH(short)
    else INTERGRAL_RT_BRANCH(int)
    else INTERGRAL_RT_BRANCH(long)
    else INTERGRAL_RT_BRANCH(long long)
    else RT_BRANCH(float)
    else RT_BRANCH(double)
    else RT_BRANCH(long double)
    else EMOCK_REPORT_FAILURE(std::string("Unsupported return type {").append(returnType.c_str()).append("}, use EMOCKX(")
      .append(returnType.c_str()).append(", \"").append(m.c_str()).append("\") instead.").c_str());
    return InvocationMockBuilderGetter(nullptr, nullptr);//缺少这句。
}

我只是默认空实现了一个。
