This script configures notmuch to build on your system. It verifies that dependencies are available, determines flags needed to compile and link against various required libraries, and identifies whether various system functions can be used or if locally-provided replacements will be built instead. Finally, it allows you to control various aspects of the build and installation process. First, some common variables can specified via environment variables: CC The C compiler to use CFLAGS Flags to pass to the C compiler CXX The C++ compiler to use CXXFLAGS Flags to pass to the C compiler LDFLAGS Flags to pass when linking Each of these values can further be controlled by specifying them later on the "make" command line. Other environment variables can be used to control configure itself, (and for which there is no equivalent build-time control): XAPIAN_CONFIG The program to use to determine flags for compiling and linking against the Xapian library. [$XAPIAN_CONFIG] Additionally, various options can be specified on the configure command line. --prefix=PREFIX Install files in PREFIX [$PREFIX] By default, "make install" will install the resulting program to $PREFIX/bin, documentation to $PREFIX/man, etc. You can specify an installation prefix other than $PREFIX using --prefix, for instance: ./configure --prefix=\$HOME Fine tuning of some installation directories is available: --libdir=DIR Install libraries to DIR [PREFIX/lib] --includedir=DIR Install header files to DIR [PREFIX/include] --mandir=DIR Install man pages to DIR [PREFIX/share/man] --sysconfdir=DIR Read-only single-machine data [PREFIX/etc] --emacslispdir=DIR Emacs code [PREFIX/share/emacs/site-lisp] --emacsetcdir=DIR Emacs miscellaneous files [PREFIX/share/emacs/site-lisp] --bashcompletiondir=DIR Bash completions files [SYSCONFDIR/bash_completion.d] --zshcompletiondir=DIR Zsh completions files [PREFIX/share/zsh/functions/Completion/Unix] Some features can be disabled (--with-feature=no is equivalent to --without-feature) : --without-emacs Do not install lisp file --without-bash-completion Do not install bash completions files --without-zsh-completion Do not install zsh completions files Additional options are accepted for compatibility with other configure-script calling conventions, but don't do anything yet: --build=<cpu>-<vendor>-<os> Currently ignored --host=<cpu>-<vendor>-<os> Currently ignored --infodir=DIR Currently ignored --datadir=DIR Currently ignored --localstatedir=DIR Currently ignored --libexecdir=DIR Currently ignored --disable-maintainer-mode Currently ignored --disable-dependency-tracking Currently ignored EOF } # Parse command-line options for option; do if [ "${option}" = '--help' ] ; then usage exit 0 elif [ "${option%%=*}" = '--prefix' ] ; then PREFIX="${option#*=}" elif [ "${option%%=*}" = '--libdir' ] ; then LIBDIR="${option#*=}" elif [ "${option%%=*}" = '--includedir' ] ; then INCLUDEDIR="${option#*=}" elif [ "${option%%=*}" = '--mandir' ] ; then MANDIR="${option#*=}" elif [ "${option%%=*}" = '--sysconfdir' ] ; then SYSCONFDIR="${option#*=}" elif [ "${option%%=*}" = '--emacslispdir' ] ; then EMACSLISPDIR="${option#*=}" elif [ "${option%%=*}" = '--emacsetcdir' ] ; then EMACSETCDIR="${option#*=}" elif [ "${option%%=*}" = '--bashcompletiondir' ] ; then BASHCOMPLETIONDIR="${option#*=}" elif [ "${option%%=*}" = '--zshcompletiondir' ] ; then ZSHCOMLETIONDIR="${option#*=}" elif [ "${option%%=*}" = '--with-emacs' ]; then if [ "${option#*=}" = 'no' ]; then WITH_EMACS=0 else WITH_EMACS=1 fi elif [ "${option}" = '--without-emacs' ] ; then WITH_EMACS=0 elif [ "${option%%=*}" = '--with-bash-completion' ]; then if [ "${option#*=}" = 'no' ]; then WITH_BASH=0 else WITH_BASH=1 fi elif [ "${option}" = '--without-bash-completion' ] ; then WITH_BASH=0 elif [ "${option%%=*}" = '--with-zsh-completion' ]; then if [ "${option#*=}" = 'no' ]; then WITH_ZSH=0 else WITH_ZSH=1 fi elif [ "${option}" = '--without-zsh-completion' ] ; then WITH_ZSH=0 elif [ "${option%%=*}" = '--with-gmime-version' ] ; then if [ "${option#*=}" = '2.4' ]; then WITH_GMIME_VERSIONS=$GMIME_24_VERSION elif [ "${option#*=}" = '2.6' ]; then WITH_GMIME_VERSIONS=$GMIME_26_VERSION fi elif [ "${option%%=*}" = '--build' ] ; then true elif [ "${option%%=*}" = '--host' ] ; then true elif [ "${option%%=*}" = '--infodir' ] ; then true elif [ "${option%%=*}" = '--datadir' ] ; then true elif [ "${option%%=*}" = '--localstatedir' ] ; then true elif [ "${option%%=*}" = '--libexecdir' ] ; then true elif [ "${option}" = '--disable-maintainer-mode' ] ; then true elif [ "${option}" = '--disable-dependency-tracking' ] ; then true else echo "Unrecognized option: ${option}" echo "See:" echo " $0 --help" echo "" exit 1 fi done # We set this value early, (rather than just while printing the # Makefile.config file later like most values), because we need to # actually investigate this value compared to the ldconfig_paths value # below. libdir_expanded=${LIBDIR:-${PREFIX}/lib} cat <<EOF Welcome to Notmuch, a system for indexing, searching and tagging your email.
