Installation
This page covers how to install and run Miking natively on your system. See other installation methods at the bottom of this page for options.
Install Miking​
Required Dependencies
You need to install Opam (OCaml package manager) before you can use the Miking system. See the Opam installation guide for how to install Opam on Mac or on your Linux distribution: Link
For Windows, install Opam using Windows Subsystem for Linux (WSL).
With opam
installed, create a switch for Miking and install the packages
dune
and linenoise
. Do that by running the following:
opam update
opam switch create miking-ocaml 5.0.0
eval $(opam env)
opam install dune linenoise menhir ocamlfind
If Using Multiple Opam Switches
Note that the opam switch
command lets you have several OCaml installations on
your system. When using the Miking system, you need to use the miking-ocaml
switch. Running opam switch miking-ocaml
followed by eval $(opam env)
always takes you back to the correct switch.
Clone the Miking git repository to a suitable location on your system and enter the directory:
git clone https://github.com/miking-lang/miking.git
cd miking
If you do not have git
installed on your system then you can manually
download a zip file with the source code from our GitHub page:
https://github.com/miking-lang/miking/archive/refs/heads/develop.zip
Assuming that you have downloaded the repository and are currently located in
that directory, then you can either install Miking on your system with make
or directly using your shell:
Install
- Makefile
- Shell
With make
available, you can install Miking as:
make install
If make
is not available on your system, then you can directly install Miking
by running the provided make.sh
shell script as:
./make.sh boot && ./make.sh install-boot && ./make.sh && ./make.sh install
This will install the mi
binary under $HOME/.local/bin
, as well as the
standard library under $HOME/.local/lib
. If not already, make sure that
$HOME/.local/bin
is on your shell's PATH by running the following command
directly or adding it to the appropriate .rc-file (e.g. .bashrc
or .zshrc
):
export PATH="$HOME/.local/bin:$PATH"
This concludes the basic installation. You can now compile and run MCore
programs using mi compile
:
> echo 'mexpr print "Hello, Miking!\n"' > hello.mc
> mi compile hello.mc
> ./hello
Hello, Miking!
See the documentation page for more usage.
Uninstall
- Makefile
- Shell
To uninstall Miking, run the following in the cloned Miking repository:
make uninstall
To uninstall Miking, run the following in the cloned Miking repository:
./make.sh uninstall
Optional Dependencies​
Certain parts of the standard library depends on additional OCaml packages to properly function. See below for how to install them for your system:
Optional Dependencies
- Linux
- Mac (Intel x86)
- Mac (Apple Silicon)
Install the dependencies with Opam:
opam install pyml toml lwt owl.0.10.0 ocamlformat.0.24.1 conf-openblas.0.2.1
Opam should invoke your distribution's package manager if there are any additional dependencies needed.
It might be necessary to add openblas to the pkg-config path if installed with
Homebrew. Replace /usr/local
in the PKG_CONFIG_PATH
variable below with
your Homebrew prefix if they differ.
# Install openblas
brew install openblas
# Double check if /usr/local is what your Homebrew installation uses as its
# prefix. Change if it is different.
export PKG_CONFIG_PATH="/usr/local/opt/openblas/lib/pkgconfig:${PKG_CONFIG_PATH}"
# Now install the dependencies with Opam:
opam install pyml toml lwt owl.0.10.0 ocamlformat.0.24.1 conf-openblas.0.2.1
Before installing the Opam packages, it is most likely necessary to perform the following steps before proceeding with the installation:
# Install gcc and openblas
brew install gcc openblas
# Make sure that you have gcc as your cc compiler (change version from 12 to
# your GCC version if it is different)
cd $HOMEBREW_PREFIX/bin && ln -s gcc-12 cc
Now verify that your cc
compiler points to the correct location by running
which cc
. You might need to open a new terminal window for this.
Once cc
points to the correct location, run the following commands to install
the remaining dependencies:
export PKG_CONFIG_PATH="$HOMEBREW_PREFIX/opt/openblas/lib/pkgconfig:${PKG_CONFIG_PATH}"
export OWL_CFLAGS="-g -O3 -Ofast -funroll-loops -ffast-math -DSFMT_MEXP=19937 -fno-strict-aliasing -Wno-tautological-constant-out-of-range-compare"
export OWL_AEOS_CFLAGS="-g -O3 -Ofast -funroll-loops -ffast-math -DSFMT_MEXP=19937 -fno-strict-aliasing"
export EIGENCPP_OPTFLAGS="-Ofast -funroll-loops -ffast-math"
export EIGEN_FLAGS="-O3 -Ofast -funroll-loops -ffast-math"
# If opened a new terminal window, make sure to run `eval $(opam env)` first
opam install pyml toml lwt owl.0.10.0 ocamlformat.0.24.1 conf-openblas.0.2.1
You can now remove the cc
symlink created earlier.
Other Installation Methods​
There are various packaging options for Miking including nix
, guix
, and a
self-contained tarball. See the README under misc/packaging
directory in the Miking repository for more information.
We also provide Docker images for
Miking on Docker Hub that come
with a prebuilt mi
binary and all dependencies. See the documentation on
Docker Hub for how to run it.
