I foolishly did not "cut-and-paste" the > 'rpmbuild' command but wrote it myself. They are "back ticks" :-) This is one of those things that might be regarded as Unix/Linux basics (?). It feeds the output of the command inside the ticks to the shell. In your case, `uname -m` produces i686 which then will be used as the parameter for the --target= option. > I realize there is another thread about these Wiki pages currently being > discussed on centos-docs list but I thought it better to start a new > thread. Yes, this is a new subject, so you did it just fine. Thank you for writing this note to share what you have noticed. The Wiki article shall be modified accordingly. Akemi > TIA, Antti
