Package: autoconf
Version: 2.65-3
Severity: normal
In MPFR, we had in configure.in:
if test -n $variable_indefinie ; then
AC_PROG_CXX([g++])
AC_PROG_F77([g77])
AC_PROG_CXXCPP
fi
This doesn't seem to be forbidden according to the autoconf
documentation. Even though the test
test -n $variable_indefinie
is always false, the configure script checks for the GNU Fortran 77
compiler.
To reproduce the problem:
$ svn checkout svn://scm.gforge.inria.fr/svn/mpfr/tr...@6694 mpfr
$ cd mpfr
$ autoreconf -i
$ ./configure
In the configure output:
checking for g77... no
checking for xlf... no
checking for f77... no
checking for frt... no
checking for pgf77... no
checking for cf77... no
checking for fort77... no
checking for fl32... no
checking for af77... no
checking for xlf90... no
checking for f90... no
checking for pgf90... no
checking for pghpf... no
checking for epcf90... no
checking for gfortran... no
checking for g95... no
checking for xlf95... no
checking for f95... no
checking for fort... no
checking for ifort... no
checking for ifc... no
checking for efc... no
checking for pgf95... no
checking for lf95... no
checking for ftn... no
checking whether we are using the GNU Fortran 77 compiler... no
But if one replaces
AC_PROG_F77([g77])
by
dnl AC_PROG_F77([g77])
and rerun autoreconf -i and ./configure, the above lines are
no longer there. There seems to be a similar problem for:
AC_PROG_CXX([g++])
