问题

我已经在https://stackoverflow.com/questions/16710047/usr-bin-ld-cannot-find-lnameofthelibrary上查看了答案，但它们都不适用于这种情况。

我刚刚买了一台新笔记本电脑并设置了Go。一个简单的Hello World程序可以运行，但是当我尝试运行一个更复杂的程序时，我遇到了以下错误：

  1. go run .
  2. # runtime/cgo
  3. /usr/bin/ld: cannot find -lavcodec
  4. /usr/bin/ld: cannot find -lavformat
  5. /usr/bin/ld: cannot find -lavutil
  6. /usr/bin/ld: cannot find -lswscale
  7. /usr/bin/ld: cannot find -lswresample
  8. /usr/bin/ld: cannot find -lavdevice
  9. /usr/bin/ld: cannot find -lavfilter
  10. collect2: error: ld returned 1 exit status

我不确定错误发生在我的程序的哪个位置，因为上面是我得到的唯一输出。

  1. $ gcc --version
  2. gcc (Ubuntu 10.3.0-1ubuntu1) 10.3.0

编辑：
这里有一个能够重现错误的小示例：

  1. package main
  3. import "net/http"
  5. func main() {
  6. 	cli := &http.Client{}
  7. 	rsp, err := cli.Get("https://google.com")
  8. 	if err != nil {
  9. 		panic(err)
  10. 	}
  12. 	defer rsp.Body.Close()
  14. }

这是在全新安装的Ubuntu 21.04上全新安装的Go：

Go版本：
go version go1.16.8 linux/amd64

go env的输出：

I've already reviewed the answers at https://stackoverflow.com/questions/16710047/usr-bin-ld-cannot-find-lnameofthelibrary and none of them work for this context.

I just got a new laptop and setting up Go. A simple hello world program works, but when I try a more complicated program, I get:

  1. go run .
  2. # runtime/cgo
  3. /usr/bin/ld: cannot find -lavcodec
  4. /usr/bin/ld: cannot find -lavformat
  5. /usr/bin/ld: cannot find -lavutil
  6. /usr/bin/ld: cannot find -lswscale
  7. /usr/bin/ld: cannot find -lswresample
  8. /usr/bin/ld: cannot find -lavdevice
  9. /usr/bin/ld: cannot find -lavfilter
  10. collect2: error: ld returned 1 exit status

I'm not sure where in my program the error occurs because the above is the only output I get.

  1. $ gcc --version
  2. gcc (Ubuntu 10.3.0-1ubuntu1) 10.3.0

EDIT:
Here's a small sample that reproduces the error:

  1. package main
  3. import "net/http"
  5. func main() {
  6. 	cli := &http.Client{}
  7. 	rsp, err := cli.Get("https://google.com")
  8. 	if err != nil {
  9. 		panic(err)
  10. 	}
  12. 	defer rsp.Body.Close()
  14. }

This is a brand new Go install on a brand new Ubuntu 21.04 install:

Go version:
go version go1.16.8 linux/amd64

标志“-l”用于指示链接器在构建应用程序时应使用的库。如果这是一台新的笔记本电脑，可能尚未安装这些库。您可以使用以下命令安装所需的库：

sudo apt-get update -y
sudo apt-get install -y libavfilter-dev
sudo apt-get install -y libavcodec-dev
sudo apt-get install -y libavutil-dev
sudo apt-get install -y libswscale-dev
sudo apt-get install -y libswresample-dev
sudo apt-get install -y libavdevice-dev
sudo apt-get install -y libavfilter-dev

英文:

Flag -l is used to indicate libraries that the linker is supposed to use to build your application. If it's a new laptop, it's possible that the libraries are not installed. You should be able to install the libraries needed using the following commands:

  1. sudo apt-get update -y
  2. sudo apt-get install -y libavfilter-dev
  3. sudo apt-get install -y libavcodec-dev
  4. sudo apt-get install -y libavutil-dev
  5. sudo apt-get install -y libswscale-dev
  6. sudo apt-get install -y libswresample-dev
  7. sudo apt-get install -y libavdevice-dev
  8. sudo apt-get install -y libavfilter-dev
