C++ 如何解决“问题”；非void函数缺少返回值“；tromeloeil中的错误？

我试图弄清楚如何在C++11中使用Trompeloeil库。在这个例子中，我遇到了大量的构建错误，我不明白为什么

#define CATCH_CONFIG_MAIN
#include "catch.hpp"
#include <rapidcheck.h>
#include <rapidcheck/state.h>
#include <trompeloeil.hpp>
#include "../../../include/Orion.h"
#include "../../../include/optionCheckerFileHandler.h"

class mock{
  public:
  MAKE_MOCK1(getFileParams, int(int));
};

TEST_CASE( "Factorials are computed", "[factorial]" ) {
  using trompeloeil::_;  // wild card for matching any value
  using trompeloeil::gt; // greater-than match
  mock m;{
    REQUIRE_CALL_V(m, getFileParams(1)).RETURN(0);
  }
}

如果有人能帮我理解这些，我将不胜感激。我可以根据请求提供完整的构建错误
