Mac ：xcode build failed: File name too long

[nicholaslin]

hi, buddy
as you can see above picture , when I build xcode project on the mounted fs, the file name is append its path cause file name too long ,please tell me how to solve it if you know

Sorry, I don't know how Xcode produces that long a filename, and it is fundamentally impossible to support such long filenames in format 4. You may create a format 2 securefs filesystem, or try to figure out why Xcode results in such long names.

I’m think that not just xcode file but all file that has long name directory has same problem. Because the file name has changed in securefs that had append it’s complete file path, and xcode building will generate long name directory so the phenomenon occurs

Because the file name has changed in securefs that had append it’s complete file path,

I don't understand this line. Are you saying that `securefs` is the reason that Xcode generates such long filename (XXXXXX_xcbuild.lock)?

As you can see at my first pic , when Xcode building and save file in mounted directory, the file name will change (append Users_computername......_xcodebuild.lock ,the prefix is it’s complete path),but when Xcode save to the directory that no mount it’s file name just is “xcodebuild.lock”,and then I try to mkdir a long name dir name in finder ,and then drop any file in it and drag the dir to the mounted fs,the same issue occurred,so I guess that

OK, I got it. It is very weird. I need time to investigate.
