Control: tags -1 help Hi,
I need to admit that from my naive perspective this is a bug in autoconf. In the log that is provided in the bug report[1] you can see this here: dh_autoreconf -O--buildsystem=R configure.ac:44: warning: AC_OUTPUT should be used without arguments. configure.ac:44: You should run autoupdate. configure.ac:44: warning: AC_OUTPUT should be used without arguments. configure.ac:44: You should run autoupdate. debian/rules override_dh_auto_configure make[1]: Entering directory '/<<PKGBUILDDIR>>' cd tools && ./regenerate rm: cannot remove '../Makefile': No such file or directory rm: cannot remove '../src/Makevars': No such file or directory configure.ac:44: warning: AC_OUTPUT should be used without arguments. configure.ac:44: You should run autoupdate. configure.ac:44: warning: AC_OUTPUT should be used without arguments. configure.ac:44: You should run autoupdate. This results later in: ** using staged installation configure.ac: starting ./configure: line 1764: syntax error near unexpected token `;;' ./configure: line 1764: ` as_dir=./ ;;' ERROR: configuration failed for package ‘ncdf4’ I checked the resulting configure file and the part in question looks like: echo "configure.ac: starting" as_dir=./ ;; */) ;; *) as_dir=$as_dir/ ;; esac for ac_exec_ext in '' $ac_executable_extensions; do if as_fn_executable_p "$as_dir$ac_word$ac_exec_ext"; then ac_cv_prog_HAS_NC_CONFIG="yes" printf "%s\n" "$as_me:${as_lineno-$LINENO}: found $as_dir$ac_word$ac_exec_ext" >&5 break 2 fi done It looks like a case statement intended but not injected by autoconf. I have no idea how this can be influenced by some configure.ac statement. Kind regards Andreas. [1] https://bugs.debian.org/978891 -- http://fam-tille.de
