Jim Mussared 7d2ccd027f py/mkenv.mk: Move usage of 32-bit flags to py.mk.
This allows ports/variants to configure MICROPY_FORCE_32BIT after including
mkenv.mk, but before py.mk.

Jim Mussared 8ba963cfa3 tools/makemanifest.py: Eval relative paths w.r.t. current manifest file.
When loading a manifest file, e.g. by include(), it will chdir first to the
directory of that manifest.  This means that all file operations within a
manifest are relative to that manifest's location.

As a consequence of this, additional environment variables are needed to
find absolute paths, so the following are added: $(MPY_LIB_DIR),
$(PORT_DIR), $(BOARD_DIR).  And rename $(MPY) to $(MPY_DIR) to be
consistent.

Existing manifests are updated to match.

Damien George e81f538e25 tools: Add mechanism to provide a manifest of frozen files.
This introduces a new build variable FROZEN_MANIFEST which can be set to a
manifest listing (written in Python) that describes the set of files to be
frozen in to the firmware.

Damien George fb73bdae62 py/mkenv.mk: Add GDB variable. 2019-09-05 22:59:06 +10:00
Sebastien Rinsoz a4f4239e95 py: Update makefiles to use $(TOUCH) instead of hard coded "touch".
The variable $(TOUCH) is initialized with the "touch" value in mkenv.mk
like for the other command line tools (rm, echo, cp, mkdir etc).  With
this, for example, Windows users can specify the path of touch.exe.

Sébastien Rinsoz c03f81c633 py: Update makefiles to use $(CAT) variable instead of hard coded "cat".
The variable $(CAT) is initialised with the "cat" value in mkenv.mk like
for the other command line tools (rm, echo, cp, mkdir etc).  With this,
for example, Windows users can specify the path of cat.exe.

Andrew Leech 89ff506513 py: Update and rework build system for including external C modules.
How to use this feature is documented in docs/develop/cmodules.rst.

Ayke van Laethem 2e516074da py: Implement a module system for external, user C modules.
This system makes it a lot easier to include external libraries as static,
native modules in MicroPython.  Simply pass USER_C_MODULES (like
FROZEN_MPY_DIR) as a make parameter.

Damien George 5368210e36 py/mkenv.mk: Change default PYTHON variable from "python" to "python3".
This change makes it so that python3 is required by default to build
MicroPython. Python 2 can be used by specifying make PYTHON=python2.

This comes about due to a recent-ish change to PEP 394 that makes the
python command more optional than before (even with Python 2 installed);
see cd59ec03c8 (diff-1d22f7bd72cbc900670f058b1107d426)

Since the command python is no longer required to be provided by a
distribution we need to use either python2 or python3 as commands.  And
python3 seems the obvious choice.

Christopher Arndt 1871a924c9 py/mkenv.mk: Use $(PYTHON) consistently when calling Python tools.
Rationale:

* Calling Python build tool scripts from makefiles should be done
  consistently using `python </path/to/script>`, instead of relying on the
  correct she-bang line in the script [1] and the executable bit on the
  script being set. This is more platform-independent.
* The name/path of the Python executable should always be used via the
  makefile variable `PYTHON` set in `py/mkenv.mk`. This way it can be
  easily overwritten by the user with `make PYTHON=/path/to/my/python`.
* The Python executable name should be part of the value of the makefile
  variable, which stands for the build tool command (e.g. `MAKE_FROZEN` and
  `MPY_TOOL`), not part of the command line where it is used. If a Python
  tool is substituted by another (non-python) program, no change to the
  Makefiles is necessary, except in `py/mkenv.mk`.
* This also solves #3369 and #1616.

[1] There are systems, where even the assumption that `/usr/bin/env` always
exists, doesn't hold true, for example on Android (where otherwise the unix
port compiles perfectly well).

Damien George 02b4b23319 Revert "py/{mkenv.mk,mkrules.mk}: Append .exe for Windows executable files."
This reverts commit 3289b9b7a7.
The commit broke building on MINGW because the filename became
micropython.exe.exe.  A proper solution to support more Windows build
environments requires more thought and testing.

chrismas9 3289b9b7a7 py/{mkenv.mk,mkrules.mk}: Append .exe for Windows executable files.
Building mpy-cross: this patch adds .exe to the PROG name when building
executables for host (eg mpy-cross) on Windows.  make clean now removes
mpy-cross.exe under Windows.

Building MicroPython: this patch sets MPY_CROSS to mpy-cross.exe or
mpy-cross so they can coexist and use cygwin or WSL without rebuilding
mpy-cross.  The dependency in the mpy rule now uses mpy-cross.exe for
Windows and mpy-cross for Linux.

Damien George bdf33bc136 py: Move frozen bytecode Makefile rules from ports to common mk files.
Now, to use frozen bytecode all a port needs to do is define
FROZEN_MPY_DIR to the directory containing the .py files to freeze, and
define MICROPY_MODULE_FROZEN_MPY and MICROPY_QSTR_EXTRA_POOL.

Paul Sokolovsky f28efa1971 py: Move frozen modules rules from esp8266 port for reuse across ports.
A port now just needs to define FROZEN_DIR var and add $(BUILD)/frozen.c
to SRC_C to support frozen modules.

Damien George 109990fc32 py/mkenv.mk: Remove -s and -S args from PYTHON variable.
Qstr auto-generation is now much faster so this optimisation for start-up
time is no longer needed.  And passing "-s -S" breaks some things, like
stmhal's "make deploy".

Paul Sokolovsky 408b74d74c py: Allow to to build MicroPython as a static library.
The whole current port gets slurped into a static lib named
"libmicropython.a". Maybe that's not ideal, but at least something
to start with.

Paul Sokolovsky 18c22faf4d py: Treat -m32 flag as part of CC, LD, etc.
Indeed, this flag efectively selects architecture target, and must
consistently apply to all compiles and links, including 3rd-party
libraries, unlike CFLAGS, which have MicroPython-specific setting.

Damien George 82ed3d62f6 py, mk: Revert change where build variables set with ?=.
?= operator does not do delayed expansion (unlike =).

Marcus von Appen 8ffc02495f - Let the build environment decide about the toolchain to be used, in case
there are special tweaks and paths to be considered. Just provide some
  defaults, in case the values are undefined.
- py-version.sh does not need any bash specific features.
- Use libdl only on Linux for now. FreeBSD provides dl*() calls from libc.
