[Pw_forum] Installation problem (ranlib) on Mac Intel -- HELP !!!

[Andrea Ferretti]

Hi Riccardo,

it seems your problem is related to the building of .a libraries, 
more problably due to "ar", instead of "ranlib"...
I sort of remeber I got a similar problem on intel Mac, and the solution 
was to set AR and ARFLAGS to some standard values (in my case they 
where set in a different, mac-oriented, way), like

AR             = ar
ARFLAGS        = ruv

actually, don't know if this is your case...

anyway, if you didn't already, see also the section related to Mac at: 
http://www.quantum-espresso.org/wiki/index.php/Installation

cheers
