Why MSYS can't recognize tar-ustar option in AM_INIT_AUTOMAKE?

When I'm trying to run autogen from MSys 1.11 on a source, it always giving an error called,

configure.ac:9: option 'tar-ustar' not recognized

Can anyone please help me to get-rid of this error ?

Note: andtar-v7, tar-ustar, tar-pax. all these 3 didn't work. Thank you开发者_如何学Go...

Just remove the tar-ustar option from your configure.ac file (look for an AM_INIT_AUTOMAKE line) or install a newer version of Automake (1.9+). It should fall back to v7-style tar (in spite of not recognizing tar-v7).

tar is the command - the '-' and the letters after it is a parameter. You want:

 tar -ustar

notice the space. Having said that, I don't believe that -ustar is a valid combination of tar options, but you should get a different error message for that.
