编译出错:go build github.com/ying32/govcl/vcl/api: /usr/local/go/pkg/tool/linux_amd64/compile: signal: killed

[hehehahayang]

• ubuntu20
• go version go1.16.5 linux/amd64
• go get github.com/ying32/govcl v2.0.10+incompatible
• demo为你的示例2
• 编译命令: GOARCH=amd64 GOOS=linux CGO_ENABLED=1 go build -o xxx xxx.go
• 约1分钟左右报错: go build github.com/ying32/govcl/vcl/api: /usr/local/go/pkg/tool/linux_amd64/compile: signal: killed

补充:

• 在ubuntu20下编译win64的exe,可以编译,并且可以运行成功, 编译命令:GOARCH=amd64 GOOS=windows CGO_ENABLED=0 go build -v -x -buildmode=exe -o xxx xxx.go
• 用楼上的命令编译linux64, 不通过,于是我增加编译参数
• GOARCH=amd64 GOOS=linux CGO_ENABLED=1 go build -v -x -o xxx xxx.go
• 编译输出

• 找到kill的原因了.

• 为什么编译过程中会占用如此大量的内存? 是正常吗?

[ying32]

这个问题你得问google为啥要这么大量的内存，这个问题也是从go1.16开始才有的，用govcl dev分支的可以在linux下成功编译。
