[CPMD-list] CPMD compile error (etime...)

[Rodolphe Vuilleumier]

Dear Robel,

in the file timec.F change the following lines
#elif defined(__PRIMEQUEST) || defined(__alpha) || defined(__SUN) || 
defined(__PGI) || defined(__ABSOFT)
      REAL*4 ETIME,TARRAY(2),D
      EXTERNAL ETIME
C     ==--------------------------------------------------------------==
      D=ETIME(TARRAY)
      TIMEC = DBLE(TARRAY(1))*1000.D0

to
#elif defined(__PRIMEQUEST) || defined(__alpha) || defined(__SUN) || 
defined(__PGI) || defined(__ABSOFT)
      REAL*4 TARRAY(2),D
C     ==--------------------------------------------------------------==
      D=ETIME(TARRAY)
      TIMEC = DBLE(TARRAY(1))*1000.D0

in the new gfortran (4.2) ETIME is an intrinsic and so should not be 
defined as EXTERNAL.

You could prefer instead of changing the lines above add a few lines as 
follows:
#elif defined(__PRIMEQUEST) || defined(__alpha) || defined(__SUN) || 
defined(__PGI) || defined(__ABSOFT)
      REAL*4 ETIME,TARRAY(2),D
      EXTERNAL ETIME
C     ==--------------------------------------------------------------==
      D=ETIME(TARRAY)
      TIMEC = DBLE(TARRAY(1))*1000.D0
#elif defined(__GNU)
      REAL*4 TARRAY(2),D
C     ==--------------------------------------------------------------==
      D=ETIME(TARRAY)
      TIMEC = DBLE(TARRAY(1))*1000.D0
#elif defined(__WINNT)
....
and delete -D__PGI in the CPPFLAGS line of your Makefile.

All the best,
Rodolphe
