Building

General information about building the Octave source for different operating systems.

General steps

Build from the development repository

Build from a release

Install all build dependencies (see below).

hg clone https://www.octave.org/hg/octave && \
cd octave                                  && \
./bootstrap

wget https://ftpmirror.gnu.org/octave/octave-9.2.0.tar.gz && \
tar -xzf octave-9.2.0.tar.gz

mkdir .build                            && \
cd    .build                            && \
./../configure --prefix=$HOME/my_octave && \ ^[1]
make -j2                                && \ ^[2]
make check                              && \
make install
