In autoconf 2.58, ./lib/autoconf/fortran.m4 has a list of Fortran 77, 90, and 95 compilers that initialize _AC_F77_FC, _AC_F90_FC, and _AC_F95_FC. The _AC_F95_FC list contains ifc: # ifc: Intel Fortran 95 compiler for Linux/x86 Effective yesterday with the release of version 8.0 of the Intel Fortran compiler, the preferred name is now ifort, with ifc retained for compatibility, but issuing a warning: % ifort hello.f90 && ./a.out hello ... This is a Fortran 90 program! % ifc hello.f90 && ./a.out ifc: warning: The Intel Fortran driver is now named ifort. You can suppress this message with '-quiet' hello ... This is a Fortran 90 program! In earlier releases, the IA-32 compiler was ifc, and the IA-64 compiler, efc. From version 8.0, both are called ifort. Please consider updating the list from m4_define([_AC_F95_FC], [f95 fort xlf95 ifc efc pgf95 lf95 gfortran]) to m4_define([_AC_F95_FC], [f95 fort xlf95 ifort ifc efc pgf95 lf95 gfortran]) so that ifort is preferred over ifc. Also, I think that pgf95 should be removed, since it doesn't exist. See http://www.pgroup.com/faq/ The _AC_F90_FC list might possibly be augmented with pghpf, the Portland Group High-Performance Fortran (a Fortran dialect based on Fortran 90) compiler. Please note that ./lib/autoconf/fortran.m4 is not the only file that may need updates: I find mentions of Fortran compiler names in these files: % egrep -l '\b(f77|xlf|cf77|cft77|pgf77|fl32|af77|fort77|f90|xlf90|pgf90|epcf90|f95|xlf95|lf95|g95|fc|fort|ifc|ifort)\b' `find . -type f` ./autoconf.m4f ./autoheader.m4f ./aclang.m4 ./autoconf/fortran.m4 ./autoconf/autoconf.m4f It seems undesirable to me that such duplications are present, since it makes maintenance error prone; for example, in the first of these, I find AC_CHECK_TOOLS(F77, [m4_default([$1], [g77 f77 xlf cf77 cft77 frt pgf77 fl32 af77 fort77 f90 xlf90 pgf90 epcf90 f95 fort xlf95 lf95 g95 fc])]) ------------------------------------------------------------------------------- - Nelson H.
