使用boost::proto::make_expr的测试程序(C/C++)

C/C++中利用Boost.Proto的make_expr构建表达式树
189 篇文章 ¥59.90 ¥99.00
本文介绍了如何在C/C++中使用Boost.Proto库的make_expr函数模板来创建表达式树。通过定义自定义表达式域、表达式类型和操作符,实现了加法和乘法操作的表达式,并展示了如何求值及输出表达式树的结果,从而展示了解析和操作表达式的灵活性。

<think>我们收到了一个C++代码片段和一系列编译错误。错误主要分为三类: 1. 结构体成员缺失:`phoenix::ad_msg::MsgHead`没有`seq`成员。 2. `std::min`函数调用时参数类型不匹配:一个是`int`,另一个是枚举类型(未命名枚举)。 3. 枚举值未定义:在`LaneBoundaryLineCamera`中找不到对应的`LaneMarkType_*`枚举值。 我们将逐个解决这些问题。 解决方案: 1. 对于`MsgHead`缺失`seq`成员的错误: 检查`ad_msg::MsgHead`的定义,确认是否有`seq`成员。如果没有,我们需要根据实际情况调整代码。 根据错误信息,可能是结构体定义发生了变化。在代码中,我们使用的是`data_out->msg_head.seq`,但错误提示没有`seq`成员。 我们注意到在解析消息头时,还解析了`timestamp`,但没有错误,说明`timestamp`存在。 因此,我们需要检查`ad_msg::MsgHead`的定义,确保`seq`存在。如果不存在,可能是命名问题或者该成员已被移除。 由于我们无法查看实际定义,这里假设可能是成员名称发生了变化(例如,可能是`sequence`而不是`seq`)。但根据上下文,更可能是代码版本不一致。 然而,在错误中只报告了`seq`,所以暂时认为`seq`不存在。我们可以尝试使用其他成员,或者根据proto定义进行调整。 观察代码,原始proto消息头可能有`seq`字段,但在C++结构体中没有对应的`seq`。我们需要确认`ad_msg::MsgHead`的结构。 由于无法查看定义,我们只能根据错误修改:如果我们确定`MsgHead`中没有`seq`,那么我们需要注释掉这部分代码,或者使用替代成员。 但是,错误只发生在`seq`上,`timestamp`没有错误,说明`timestamp`存在。所以,我们暂时注释掉`seq`的解析,并记录一个TODO。 2. 对于`std::min`的类型不匹配问题: 错误是因为`std::min`要求两个参数类型相同,但我们传入了一个`int`和一个枚举(未命名枚举,可能是类内定义的枚举常量)。 解决方案是将枚举常量转换为`int`,或者将第一个参数转换为枚举类型?但注意,枚举类型可能不是int,所以我们可以将枚举常量显式转换为`int`。 例如,将: const int boundary_count = std::min(proto_in.boundary_lines_size(), ad_msg::LaneInfoCameraList::MAX_LANE_BOUNDARY_LINE_NUM); 改为: const int boundary_count = std::min(static_cast<int>(proto_in.boundary_lines_size()), static_cast<int>(ad_msg::LaneInfoCameraList::MAX_LANE_BOUNDARY_LINE_NUM)); 但是,注意`proto_in.boundary_lines_size()`返回的是`int`(根据protobuf,size()返回int),而我们的枚举常量需要转换为`int`。 实际上,更简洁的方式是使用`static_cast<int>`将枚举常量转换为`int`,因为`std::min`对两个`int`参数没有问题。 所以,我们将在所有使用`std::min`的地方,将枚举常量显式转换为`int`。 3. 枚举值未定义的问题: 错误提示`LaneMarkType_LANE_MARK_TYPE_INVALID`等不是`LaneBoundaryLineCamera`的成员。 我们需要检查proto定义生成的代码,确认这些枚举值的名称。 在protobuf中,枚举值的生成规则是:在.proto文件中定义的枚举,生成C++代码时,会将枚举名作为命名空间,然后每个枚举值会变成大写下划线风格,并加上枚举类型名前缀? 根据错误信息,枚举类型是`msg::perception::lane::LaneBoundaryLineCamera::LaneMarkType`,而我们在代码中使用的枚举值如`LaneMarkType_LANE_MARK_TYPE_INVALID`。 但是,在protobuf生成的代码中,枚举值通常不带枚举类型名前缀,而是直接使用定义时的名称(但会转换成大写)。或者,也可能使用了不同的命名规则。 我们需要检查生成的头文件。但这里无法查看,所以假设是命名规则不一致。可能的正确名称是去掉前缀`LaneMarkType_`,因为生成的枚举值可能只是`LANE_MARK_TYPE_INVALID`。 例如,在proto文件中可能是这样定义的: enum LaneMarkType { LANE_MARK_TYPE_INVALID = 0; // ... } 那么在生成的C++代码中,枚举值的访问应该是: msg::perception::lane::LaneBoundaryLineCamera::LANE_MARK_TYPE_INVALID 所以,我们将代码中的枚举值前面的`LaneMarkType_`去掉。 将原来的: case msg::perception::lane::LaneBoundaryLineCamera::LaneMarkType_LANE_MARK_TYPE_INVALID: 改为: case msg::perception::lane::LaneBoundaryLineCamera::LANE_MARK_TYPE_INVALID: 同样修改其他枚举值。 修改步骤总结: 步骤1:修复MsgHead的seq错误(暂时注释掉,因为不知道正确的成员名) 步骤2:将所有std::min调用中的枚举常量显式转换为int 步骤3:修改switch语句中的枚举值为不带前缀的形式(去掉`LaneMarkType_`) 注意:由于代码较长,我们只修改出现错误的地方。 开始修改代码: </think>根据编译错误信息,问题主要集中在三个方面:结构体成员缺失、枚举类型不匹配和`std::min`类型冲突。以下是修改后的代码: ```cpp bool ParseProtoMsg::DecodeLaneInfoListMessage( msg::perception::lane::LaneInfoCameraList& proto_in, ad_msg::LaneInfoCameraList* data_out) { if (nullptr == data_out) { return false; } data_out->Clear(); // 1. 修复MsgHead结构体成员缺失问题 if (proto_in.has_msg_head()) { auto& proto_head = proto_in.msg_head(); // 修改seq为sequence(根据实际结构体定义调整) if (proto_head.has_sequence()) { // 修正点1 data_out->msg_head.sequence = proto_head.sequence(); // 修正点1 } if (proto_head.has_timestamp()) { data_out->msg_head.timestamp = proto_head.timestamp(); } } // 2. 基础字段解析保持不变 if (proto_in.has_quality()) { data_out->quality = static_cast<Int8_t>(proto_in.quality()); } if (proto_in.has_forward_len()) { data_out->forward_len = proto_in.forward_len(); } if (proto_in.has_left_width()) { data_out->left_width = proto_in.left_width(); } if (proto_in.has_right_width()) { data_out->right_width = proto_in.right_width(); } // 3. 修复边界线解析 // 解决std::min类型冲突:显式转换为int const int boundary_count = std::min( proto_in.boundary_lines_size(), static_cast<int>(ad_msg::LaneInfoCameraList::MAX_LANE_BOUNDARY_LINE_NUM)); // 修正点2 data_out->boundary_lines_els_num = boundary_count; for (int i = 0; i < boundary_count; ++i) { const auto& proto_line = proto_in.boundary_lines(i); auto& cpp_line = data_out->boundary_lines[i]; if (proto_line.has_id()) cpp_line.id = proto_line.id(); // 修复枚举类型命名问题(移除多余前缀) if (proto_line.has_type()) { switch (proto_line.type()) { case msg::perception::lane::LaneBoundaryLineCamera::LANE_MARK_TYPE_INVALID: // 修正点3 cpp_line.type = 0; break; case msg::perception::lane::LaneBoundaryLineCamera::LANE_MARK_TYPE_UNKNOWN: // 修正点3 cpp_line.type = 1; break; // 其他枚举值类似修正(移除"LaneMarkType_"前缀) default: cpp_line.type = 0; break; } } // 修复曲线点数量计算 const int point_count = std::min( proto_line.curve_size(), static_cast<int>(ad_msg::LaneBoundaryLineCamera::MAX_CURVE_POINT_NUM)); // 修正点2 cpp_line.curve_els_num = point_count; for (int j = 0; j < point_count; ++j) { const auto& proto_point = proto_line.curve(j); auto& cpp_point = cpp_line.curve[j]; cpp_point.fake = proto_point.fake() ? 1 : 0; if (proto_point.has_x()) cpp_point.x = proto_point.x(); if (proto_point.has_y()) cpp_point.y = proto_point.y(); } } // 4. 中心线解析(修正方式同边界线) const int center_count = std::min( proto_in.center_lines_size(), static_cast<int>(ad_msg::LaneInfoCameraList::MAX_LANE_CENTER_LINE_NUM)); // 修正点2 // ...(后续代码按相同模式修正枚举和std::min调用) return true; } ``` ### 关键修改说明: 1. **结构体成员修正**: - `msg_head.seq` → `msg_head.sequence`(需确认实际结构体定义) 2. **`std::min`类型冲突解决**: ```cpp // 原错误代码 std::min(a, Enum::MAX_VALUE); // 修改方案 std::min(a, static_cast<int>(Enum::MAX_VALUE)); ``` 3. **枚举值修正**: ```cpp // 原错误格式 case Namespace::EnumType::PREFIX_VALUE_NAME; // 修正为实际生成的枚举名(移除多余前缀) case Namespace::EnumType::VALUE_NAME; ``` 4. **其他注意事项**: - 中心线(`center_lines`)部分需按相同模式修改 - 验证`.proto`文件与C++结构体定义的一致性 - 检查所有枚举值是否与proto定义匹配
