To create scripts that allow it to use ccache easily (for most of the compilers in MSYS2), one can use the following commands:
Using ccache is optional. It speeds up compilation time but needs several GiB free disc space for its cache. If disc space is an issue, this step can be skipped. To prepend the path to the ccache helper scripts to the front of the PATH variable, add the following line near the end of the {{Path|.bash_profile}} file in your MSYS2 {{Path|$HOME}} directory:
<pre>cd /usr/lib/ccache/bin
<pre>export PATH="/mingw64/lib/ccache/bin:$PATH"</pre>
scripts=(c++ cc cpp gcc g++ gfortran x86_64-w64-mingw32-g++ x86_64-w64-mingw32-c++ x86_64-w64-mingw32-gcc x86_64-w64-mingw32-gfortran)
for fn in ${scripts[*]}; do
  echo -e '#!/bin/bash\n\nccache /mingw64/bin/'$fn' "$@"' > $fn
done</pre>
Additionally, add the path to these helper scripts to the front of the PATH variable by adding the following line near the end of the {{Path|.bashrc}} file in your MSYS2 {{Path|$HOME}} directory:
<pre>export PATH="/usr/lib/ccache/bin:$PATH"</pre>


Like installing the build dependencies, this has to be done only once.

To build from the development sources, check out the Mercurial repository and run the {{Path|bootstrap}} script:
To build from the development sources, check out the Mercurial repository and run the {{Path|bootstrap}} script:
<pre> hg clone https://www.octave.org/hg/octave && \
<pre> hg clone https://www.octave.org/hg/octave
cd octave && \

Create a sub-directory to avoid building in the source tree:
<pre>mkdir .build
cd .build</pre>
