为 Windows 编译具有 C 依赖项的 go 程序

Question

Building go works fine for pure go project with pure go dependencies. But when building a project with a C dependency, it fails on Windows:

go build -a -o bin/xyz.exe ./xyz/main.go
go: downloading gopkg.in/confluentinc/confluent-kafka-go.v1 v1.4.2
go: downloading github.com/confluentinc/confluent-kafka-go v1.4.2
# gopkg.in/confluentinc/confluent-kafka-go.v1/kafka
In file included from C:\Users\VssAdministrator\go\pkg\mod\gopkg.in\confluentinc\confluent-kafka-go.v1@v1.4.2\kafka\00version.go:24:
./librdkafka/rdkafka.h:83:10: fatal error: sys/socket.h: No such file or directory
 #include <sys/socket.h> /* for sockaddr, .. */
          ^~~~~~~~~~~~~~
compilation terminated.
mingw32-make: *** [Makefile:10: build-windows] Error 2
##[error]Cmd.exe exited with code '2'.
Finishing: CmdLine

As can be seen from the output above, I'm using a Makefile, and my azure-pipelines.yml looks like this:

...
- script: 'make package-windows'
...

Here's my Makefile:

build-windows:
    go build -a -o bin/xyz.exe ./xyz/main.go

I also tried setting GOOS and GOARCH, to no avail:

build-windows:
    GOOS=windows GOARCH=amd64 go build -a -o bin/xyz.exe ./xyz/main.go

So how can I build this?

Answer 1

This doesn't have much to do with Go - it seems you're doing everything correctly in that regard. The issue is that the library you're using needs sys/socket.h which simply doesn't exist on Windows (see Using sys/socket.h functions on windows ).

Your options are similar to what's mentioned in the other answer:

1. Try to build using Cygwin .
2. Modify the library to use Winsock instead of sys/socket.h .
3. Find a different library, one that supports Windows (the author of the library you're using specifically said Windows is not supported ).
