Answer 1

不同的操作系统有不同的 dist 包管理器，你可以尝试在你的 Linux 系统中安装 Java 环境， 参考如下

Answer 2

It looks like you are specifying the -cp argument incorrectly.

On Linux, the path separator character is ":" not ";" . The ";" character separates commands on the command line, assuming that you are using bash or similar as your shell.

It looks like your command has been interpreted as two commands:

$ javac -g -cp ../dist_windows_x86_64/something
$ . GPUGalaxySim.java

The javac command fails because there are no source filenames on that command line ... just like the error message says.

Then the second command:

• The dot command ( "." ) is a built-in shell command that "sources" a file and attempts to interpret it as shell commands.

• If you attempt to "source" a file that is actually Java source code, you get nonsense error messages, basically because the shell has no clue what Java code means.
