This gives some notes on obtaining the tools required for development. I.E. the tools checked for by the bootstrap script and include: - Autoconf - Automake - Bison - Gettext - Git - Gperf - Gzip - Perl - Pkg-config - Rsync - Tar - Texinfo - XZ Utils Note please try to install/build official packages for your system. If these programs are not available use the following instructions to build them and install the results into a directory that you will then use when building this package. Even if the official version of a package for your system is too old, please install it, as it may be required to build the newer versions. The examples below install into $HOME/grep/deps/, so if you are going to follow these instructions, first ensure that your $PATH is set correctly by running this command: prefix=$HOME/grep/deps export PATH=$prefix/bin:$PATH * autoconf * # Note Autoconf 2.62 or newer is needed to build automake-1.11.1 git clone --depth=1 git://git.sv.gnu.org/autoconf.git git checkout v2.62 autoreconf -vi ./configure --prefix=$prefix make install * automake * # Note help2man is required to build automake fully git clone git://git.sv.gnu.org/automake.git cd automake git checkout v1.11.1 ./bootstrap ./configure --prefix=$prefix make install This package uses XZ utils (successor to LZMA) to create a compressed distribution tarball. Using this feature of Automake requires version 1.10a or newer, as well as the xz program itself. * xz * git clone git://ctrl.tukaani.org/xz.git cd xz ./autogen.sh ./configure --prefix=$prefix make install Now you can build this package as described in README-hacking.
