[英]Go Build Error "build constraints exclude all Go files" when GOARCH=386 with import "C"
I'm using CGO package to import C code, and I want to build an x86
( 386 ) windows version of it. I'm using CGO package to import C code, and I want to build an
x86
( 386 ) windows version of it. I found out this should be done by setting GOARCH=386
.我发现这应该通过设置
GOARCH=386
来完成。 It builds properly on my default environment settings (GOARCH=amd64), however, when I set the environment variable to "386", I get error: build constraints exclude all Go files in my file.它在我的默认环境设置 (GOARCH=amd64) 上正确构建,但是,当我将环境变量设置为“386”时,出现错误:构建约束排除了我文件中的所有 Go文件。
// hello.go
package main
/*
int CFunc() {
}
*/
import "C"
import (
"fmt"
)
func main() {
fmt.Println("Hello, Go!")
}
go.mod
module hello
go 1.16
I do:我愿意:
go build
I get:我得到:
C:\Users\basse\source\repos\xhptdc8_babel\go\info\hello>go build
package hello: build constraints exclude all Go files in C:\Users\basse\source\repos\xhptdc8_babel\go\info\hello
Trials:试验:
All details are found in Go Issue所有详细信息都可以在Go 问题中找到
Setting环境
set CGO_ENABLED=1
Generates another type of errors:产生另一种类型的错误:

Problem solved, thanks to @JimB.感谢@JimB,问题解决了。
In the code, make sure you use import "C"
& the correct CGO
directives/libraries In go code, like:在代码中,确保在 go 代码中使用
import "C"
和正确的CGO
指令/库,例如:
/*
#cgo CFLAGS: -Wall -g -I../../../../lib/include/
#cgo 386 LDFLAGS: -L./ -l:../../../../lib/x86dummy/xhptdc8_driver
#include "xhptdc8_interface.h"
*/
import "C"
And, when building the code, make sure you run the following commands:并且,在构建代码时,请确保运行以下命令:
set GOARCH=386
set CGO_ENABLED=1
set GOGCCFLAGS=-m32
Detailed steps and lessons learned are mentioned Build Go code that uses CGO and Custom Library详细步骤和经验教训都提到了使用 CGO 和自定义库构建 Go 代码
