windows下使用confluent-kafka-go包报错undefined: kafka.Producer

报错undefined: kafka.Producer

打开ide终端

执行go env -w CGO_ENABLED=1

继续报错报错

cgo: C compiler "gcc" not found: exec: "gcc": executable file not found in %PATH%

安装gcc

下载

*gcc官网下载：​

下载README.rst.old，找到红框后面的下载地址

下载完成后，解压

添加环境变量

右键此电脑—>属性—>高级系统设置—>环境变量

找到下面的系统变量，新增环境变量，值就是上面解压后的bin文件的路径，例如D:\mingw64\bin

验证

cmd打开命令提示符，输入gcc -v

然后继续报错

解决办法：找到confluent-kafka-go包下的build_windows.go文件

**将 -lmsvcr110 增加到 **\#cgo LDFLAGS: ${SRCDIR}/librdkafka_vendor/librdkafka_windows.a -lws2_32 -lsecur32 -lcrypt32后面

再次运行代码即可

如果编译成功后，如果提示找不到 msvcr120d.dll， 下载个放到 C:\Windows\System32 下即可
