## Installing from source
|
|
|
|
The easiest way to install is via the existing generated Scheme code.
|
|
The requirements are:
|
|
|
|
- A Scheme compiler; either Chez Scheme (default), or Racket.
|
|
- `bash`, with `realpath`. On Linux, you probably already have this.
|
|
On a Mac, you can install this with `brew install coreutils`.
|
|
On FreeBSD, OpenBSD and NetBSD, you can install `realpath` and `GNU make`
|
|
using a package manager. For instance, on OpenBSD you can install all of them
|
|
with `pkg_add coreutils gmake` command.
|
|
|
|
On Windows, it has been reported that installing via `MSYS2` works
|
|
(https://www.msys2.org/). On Windows older than Windows 8, you may need to
|
|
set an environment variable `OLD_WIN=1` or modify it in `config.mk`.
|
|
|
|
On Raspberry Pi, you can bootstrap via Racket.
|
|
|
|
By default, code generation is via Chez Scheme. You can use Racket instead,
|
|
by setting the environment variable `IDRIS2_CG=racket` before running `make`.
|
|
If you install Chez Scheme from source files, building it locally,
|
|
make sure you run `./configure --threads` to build multithreading support in.
|
|
|
|
**NOTE**: On FreeBSD, OpenBSD and NetBSD you need to use `gmake` command instead
|
|
of `make` in the following steps.
|
|
|
|
### 1: Set the PREFIX
|
|
|
|
- Change the `PREFIX` in `config.mk`. The default is to install in
|
|
`$HOME/.idris2`
|
|
|
|
If you have an existing Idris 2, go to the alternative Step 2. Otherwise, read on...
|
|
|
|
Make sure that:
|
|
|
|
- `$PREFIX/bin` is in your `PATH`
|
|
- `$PREFIX/lib` is in your `LD_LIBRARY_PATH` or `DYLD_LIBRARY_PATH` if on
|
|
`macOS` (so that the system knows where to look for library support code)
|
|
|
|
### 2: Installing without an existing Idris 2
|
|
|
|
If you _don't_ have [Idris-2-in-Idris-1](https://github.com/edwinb/Idris2-boot) installed, you can build from pre-built
|
|
Chez Scheme source, as long as you have Chez Scheme installed (or,
|
|
alternatively, Racket). To do this, enter one of the following:
|
|
|
|
- `make bootstrap SCHEME=chez`
|
|
- `make bootstrap-racket`
|
|
|
|
`chez` is the executable name of the Chez Scheme compiler. You may need to
|
|
replace this with the executable for Chez Scheme on your system. This could be
|
|
`scheme`, `chezscheme` or `chezscheme9.5` or something else, depending on your
|
|
system and the Chez Scheme version.
|
|
|
|
This builds an Idris 2 compiler from scheme code output from a working Idris 2
|
|
compiler (which isn't necessarily up to date, but is up to date enough to
|
|
build the current repository). It then rebuilds using the result, and runs
|
|
the tests.
|
|
|
|
If all is well, to install, type:
|
|
|
|
- `make install`
|
|
|
|
### (Alternative 2: Installing with an existing Idris 2)
|
|
|
|
If you have [Idris-2-in-Idris-1](https://github.com/edwinb/Idris2-boot)
|
|
installed:
|
|
|
|
- `make all IDRIS2_BOOT=idris2boot`
|
|
- `make install IDRIS2_BOOT=idris2boot`
|
|
|
|
If you have an earlier version of this Idris 2 installer
|
|
|
|
- `make all`
|
|
- `make install`
|
|
|
|
### 3: (Optional) Self-hosting step
|
|
|
|
As a final step, you can rebuild from the newly installed Idris 2 to verify
|
|
that everything has worked correctly. Assuming that `idris2` is in your
|
|
`PATH`.
|
|
|
|
- `make clean` -- to make sure you're building everything with the new version
|
|
- `make all && make install`
|
|
|
|
### 4: Running tests
|
|
|
|
After `make all`, type `make test` to check everything works. This uses the
|
|
executable in `./build/exec`.
|
|
|
|
### 5: (Optional) Installing the Idris 2 API
|
|
|
|
You'll only need this if you're developing support tools, such as an external
|
|
code generator. To do so, once everything is successfully installed, type:
|
|
|
|
- `make install-api`
|
|
|
|
The API will only work if you've completed the self-hosting step, step 3, since
|
|
the intermediate code versions need to be consistent throughout.
|
|
|
|
## Installing from a package manager
|
|
|
|
### Installing using Homebrew
|
|
|
|
If you are Homebrew user you can install Idris 2 together with all the requirements
|
|
by running following command:
|
|
|
|
brew install idris2
|
