c++ - 如何使用qmake和mingw构建示例cppkafka？

我需要摆脱 cmake ，所以我想在 mingw 上构建一个 qmake 项目。请帮助我了解缺少的内容。从https://github.com/mfontanini/cppkafka构建CPPKafka
main.cpp

#include <cppkafka/cppkafka.h>
using namespace std;
using namespace cppkafka;
int main() {
    Configuration config = {    // Create the config
        { "metadata.broker.list", "127.0.0.1:9092" }
    };
    Producer producer(config);    // Create the producer
    string message = "hey there!";    // Produce a message!
    producer.produce(MessageBuilder("my_topic").partition(0).payload(message));
    producer.flush();
    return 0;
}

.pro文件

TEMPLATE = app
CONFIG += console c++14
CONFIG -= app_bundle
CONFIG -= qt
SOURCES += main.cpp
INCLUDEPATH += 'C:\Program Files\CppKafka\include' \
               'C:\Program Files\RdKafka\include' \
               'C:\boost_1_72_0' \
               'C:\Program Files\CppKafka\include\cppkafka'

LIBS +=  'C:\Program Files\RdKafka\bin\librdkafka.dll' \
         'C:\Program Files\RdKafka\bin\librdkafka++.dll' \
         -lpthread \
         -lz \
         -lstdc++ \
         'C:\Program Files\CppKafka\bin\libcppkafka.dll'

最佳答案

您需要将dllexport添加到struct HandleDeleter并进行重建。
在include\cppkafka\kafka_handle_base.h之前:

struct HandleDeleter {
        explicit HandleDeleter(const KafkaHandleBase* handle_base_ptr) : handle_base_ptr_{handle_base_ptr} {}
        void operator()(rd_kafka_t* handle);
    private:
        const KafkaHandleBase * handle_base_ptr_;
    };

后:

struct CPPKAFKA_API HandleDeleter {
        explicit HandleDeleter(const KafkaHandleBase* handle_base_ptr) : handle_base_ptr_{handle_base_ptr} {}
        void operator()(rd_kafka_t* handle);
    private:
        const KafkaHandleBase * handle_base_ptr_;
    };
