Dear carlo, QE configure script uses the default system archiver (ar) when using ifort compiler instead of intel's own wrapper (xiar); unluckily interprocedural optimization (IPO) does not work with ar. You have two possible solutions: 1. disable IPO (by setting the -noipo in F90FLAGS in file make.sys) 2. use xiar instead of ar (by setting the AR variable to xiar in file make.sys) Personally I don't think IPO gives a substantial performance increase, hence I just disable it most of the time (furthermore it's disabled by default on most ifort versions). cheers -- Lorenzo Paulatto SISSA & DEMOCRITOS (Trieste) phone: +39 040 3787 511 skype: paulatz www: http://people.sissa.it/~paulatto/ *** save italian brains *** http://saveitalianbrains.wordpress.com/
