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++]) -- System Information: Debian Release: squeeze/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 2.6.30-2-amd64 (SMP w/8 CPU cores) Locale: LANG=POSIX, LC_CTYPE=en_US.ISO8859-1 (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/dash Versions of packages autoconf depends on: ii debianutils 3.2.2 Miscellaneous utilities specific t ii m4 1.4.13-3 a macro processing language ii perl 5.10.1-9 Larry Wall's Practical Extraction Versions of packages autoconf recommends: ii automake [automaken] 1:1.11.1-1 A tool for generating GNU Standard Versions of packages autoconf suggests: pn autoconf-archive <none> (no description available) ii autoconf-doc 2.65-1 automatic configure script builder pn autoconf2.13 <none> (no description available) ii gettext 0.17-8 GNU Internationalization utilities ii gnu-standards 2010.01.27-1 GNU coding and package maintenance ii libtool 2.2.6b-2 Generic library support script -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
