PREFIX=/usr/local usage () { cat <<EOF Usage: ./configure [options]... 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/share, etc. You can specify an installation prefix other than $PREFIX using --prefix, for instance: ./configure --prefix=\$HOME EOF } # Parse command-line options for option; do if [ "${option}" = '--help' ] ; then usage exit 0 elif [ "${option%%=*}" = '--prefix' ] ; then PREFIX="${option#*=}" else echo "Unrecognized option: ${option}." echo "See:" echo " $0 --help" echo "" exit 1 fi done cat <<EOF Welcome to Notmuch, a system for indexing, searching and tagging your email. We hope that the process of building and installing notmuch is quick and smooth so that you can soon be reading and processing your email more efficiently than ever. If anything goes wrong in the configure process, you can override any decisions it makes by manually editing the Makefile.config file that it creates. Also please do as much as you can to figure out what could be different on your machine compared to those of the notmuch developers. Then, please email those details to the Notmuch list (notmuch@notmuchmail.org) so that we can hopefully make future versions of notmuch easier for you to use.
