与Gtk+的C接口构建Go；

我正在尝试构建一个Go程序，它使用外部C代码作为Gtk+的接口

这是我得到的基本Go代码（ui.h.Go）：

C代码从vala编译成一个对象文件（ui.o）和一个头文件（ui.h）：

这是合乎逻辑的，我没有提供我的对象文件。但是如果我在

ui.h.go

的cgo头中这样指定它

//#cgo LDFLAGS: ui.o
//#cgo pkg-config: gtk+-3.0
//#include "ui.h"
import "C"

我得到多个定义错误，好像它被链接了两次

# command-line-arguments
/usr/local/go/pkg/tool/linux_amd64/link: running gcc failed: exit status 1
ui.o:(.bss+0x0): multiple definition of `window'

/tmp/go-link-461834384/000000.o:(.text+0x13b): first defined here
collect2: error: ld returned 1 exit status

如何将ui.o文件正确链接到Go程序？

---

谢谢。

嗯，我发现cgo与静态库的链接很好。因此，我决定将我的

ui.o

归档到

libui.a

中，并使用

#cgo LDFLAGS:-L.-lui

将其链接起来，它工作正常
