Hi,
I suppose it is difficult for those who read this question to understand your current status. Let me ask several questions to understand your current status.
Can I ask you what operating system you are using? Also, how did you check out the source code? You might have a document or a web page you followed, right? Listing up the commands you executed and what you have seen as replies are very helpful for me to understand your current status. If I could not understand the current status from them, I may ask your current working directory, the result of `ls` or `find .`, and available disk space, which may have some private information and I do not want to ask in the first place.
Thank you,
Yoshisato.
