Building from source
Dependencies
- libtool
- make
- automake
- autoconf
Instructions
git submodule update --init # if building from git to get oniguruma
autoreconf -i # if building from git
./configure --with-oniguruma=builtin
make clean # if upgrading from a version previously built from source
make -j8
make check
sudo make install
Build a statically linked version:
make LDFLAGS=-all-static
If you're not using the latest git version but instead building a released tarball (available on the release page), skip the autoreconf step, and flex or bison won't be needed.
