The Unix version
|
|
================
|
|
|
|
The "unix" port requires a standard Unix-like environment with gcc and GNU
|
|
make. This includes Linux, BSD, macOS, and Windows Subsystem for Linux. The
|
|
x86 and x64 architectures are supported (i.e. x86 32- and 64-bit), as well as
|
|
ARM and MIPS. Making a full-featured port to another architecture requires
|
|
writing some assembly code for the exception handling and garbage collection.
|
|
Alternatively, a fallback implementation based on setjmp/longjmp can be used.
|
|
|
|
To build (see section below for required dependencies):
|
|
|
|
$ cd ports/unix
|
|
$ make submodules
|
|
$ make
|
|
|
|
Then to give it a try:
|
|
|
|
$ ./build-standard/micropython
|
|
>>> list(5 * x + y for x in range(10) for y in [4, 2, 1])
|
|
|
|
Use `CTRL-D` (i.e. EOF) to exit the shell.
|
|
|
|
Learn about command-line options (in particular, how to increase heap size
|
|
which may be needed for larger applications):
|
|
|
|
$ ./build-standard/micropython -h
|
|
|
|
To run the complete testsuite, use:
|
|
|
|
$ make test
|
|
|
|
The Unix port comes with a built-in package manager called `mip`, e.g.:
|
|
|
|
$ ./build-standard/micropython -m mip install hmac
|
|
|
|
or
|
|
|
|
$ ./build-standard/micropython
|
|
>>> import mip
|
|
>>> mip.install("hmac")
|
|
|
|
Browse available modules at
|
|
[micropython-lib](https://github.com/micropython/micropython-lib). See
|
|
[Package management](https://docs.micropython.org/en/latest/reference/packages.html)
|
|
for more information about `mip`.

|
External dependencies
|
|
=====================
|
|
|
|
The `libffi` library and `pkg-config` tool are required. On Debian/Ubuntu/Mint
|
|
derivative Linux distros, install `build-essential`(includes toolchain and
|
|
make), `libffi-dev`, and `pkg-config` packages.
|
|
|
|
Other dependencies can be built together with MicroPython. This may
|
|
be required to enable extra features or capabilities, and in recent
|
|
versions of MicroPython, these may be enabled by default. To build
|
|
these additional dependencies, in the unix port directory first execute:
|
|
|
|
$ make submodules
|
|
|
|
This will fetch all the relevant git submodules (sub repositories) that
|
|
the port needs. Use the same command to get the latest versions of
|
|
submodules as they are updated from time to time. After that execute:
|
|
|
|
$ make deplibs
|
|
|
|
This will build all available dependencies (regardless whether they are used
|
|
or not). If you intend to build MicroPython with additional options
|
|
(like cross-compiling), the same set of options should be passed to `make
|
|
deplibs`. To actually enable/disable use of dependencies, edit the
|
|
`ports/unix/mpconfigport.mk` file, which has inline descriptions of the
|
|
options. For example, to build the SSL module, `MICROPY_PY_SSL` should be
|
|
set to 1.
|
|
|
|
Debug Symbols
|
|
-------------
|
|
|
|
By default, builds are stripped of symbols and debug information to save size.
|
|
|
|
To build a debuggable version of the Unix port, there are two options
|
|
|
|
1. Run `make [other arguments] DEBUG=1`. Note setting `DEBUG` also reduces the
|
|
optimisation level, so it's not a good option for builds that also want the
|
|
best performance.
|
|
2. Run `make [other arguments] STRIP=`. Note that the value of `STRIP` is
|
|
empty. This will skip the build step that strips symbols and debug
|
|
information, but changes nothing else in the build configuration.
