MacOS下交叉编译Golang库至Linux失败求助

查阅相关文章后，我尝试执行以下命令编译Go代码为Linux平台的C共享库：

env GOOS=linux GOARCH=amd64 go build -buildmode=c-shared -o hello.so  testlib.go

执行后出现错误：

go: no Go source files

随后我启用CGO重新执行命令：

env GOOS=linux GOARCH=amd64 CGO_ENABLED=1 go build -buildmode=c-shared -o hello.so testlib.go

但出现一系列编译错误：

env GOOS=linux GOARCH=amd64 CGO_ENABLED=1 go build -buildmode=c-shared -o hello.so testlib.go
