musl-cross-make
|
||||
===============
|
||||
|
||||
This is a quick and simple makefile-based alternative for producing
|
||||
musl-based cross compilers. The current focus is on SH2/J2 Core
|
||||
targets and NOMMU (where PIE or FDPIC is mandatory) since these are
|
||||
not adequately supported by other musl cross-compiler toolchain build
|
||||
systems, but all musl-supported targets are intended to work.
|
||||
This is a the second generation of musl-cross-make, a fast, simple,
|
||||
but advanced makefile-based approach for producing musl-targeting
|
||||
cross compilers. Features include:
|
||||
|
||||
In addition to the build system, musl-cross-make provides a number of
|
||||
patches, including:
|
||||
- Single-stage GCC build, used to build both musl libc and its own
|
||||
shared target libs depending on libc.
|
||||
|
||||
- Updated versions of the musl target patches going into upstream GCC
|
||||
- Static-PIE support and optionally defaulting to PIE
|
||||
- No hard-coded absoluete paths; resulting cross compilers can be
|
||||
copied/moved anywhere.
|
||||
|
||||
- Ability to build multiple cross compilers for different targets
|
||||
using a single set of patched source trees.
|
||||
|
||||
- Nothing is installed until running "make install", and the
|
||||
installation location can be chosen at install time.
|
||||
|
||||
- Automatic download of source packages, including GCC prerequisites
|
||||
(GMP, MPC, MPFR), using https and checking hashes.
|
||||
|
||||
- Automatic patching with canonical musl support patches and patches
|
||||
which provide bug fixes and features musl depends on for some arch
|
||||
targets.
|
||||
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
The build system can be configured by providing a config.mak file in
|
||||
the top-level directory. The only mandatory variable is TARGET, which
|
||||
should contain a gcc target tuple (such as i486-linux-musl), but many
|
||||
more options are available. See the provided config.mak.dist and
|
||||
presets/* for examples.
|
||||
|
||||
To compile, run make. To install to $(OUTPUT), run "make install".
|
||||
|
||||
The default value for $(OUTPUT) is output; after installing here you
|
||||
can move the cross compiler toolchain to another location as desired.
|
||||
|
||||
|
||||
|
||||
How it works
|
||||
------------
|
||||
|
||||
The current musl-cross-make is factored into two layers:
|
||||
|
||||
1. The top-level Makefile which is responsible for downloading,
|
||||
verifying, extracting, and patching sources, and for setting up a
|
||||
build directory, and
|
||||
|
||||
2. Litecross, the cross compiler build system, which is itself a
|
||||
Makefile symlinked into the build directory.
|
||||
|
||||
Most of the real magic takes place in litecross. It begins by setting
|
||||
up symlinks to all the source trees provided to it by the caller, then
|
||||
builds a combined "src_toolchain" directory of symlinks that combines
|
||||
the contents of the top-level gcc and binutils source trees and
|
||||
symlinks to gmp, mpc, and mpfr. One configured invocation them
|
||||
configures all the GNU toolchain components together in a manner that
|
||||
does not require any of them to be installed in order for the others
|
||||
to use them.
|
||||
|
||||
Rather than building the whole toolchain tree at once, though,
|
||||
litecross starts by building just the gcc directory and its
|
||||
prerequisites, to get an "xgcc" that can be used to configure musl. It
|
||||
then configures musl, installs musl's headers to a staging "build
|
||||
sysroot", and builds libgcc.a using those headers. At this point it
|
||||
has all the prerequisites to build musl libc.a and libc.so, which the
|
||||
rest of the gcc target-libs depend on; once they are built, the full
|
||||
toolchain "make all" can proceed.
|
||||
|
||||
Litecross does not actually depend on the musl-cross-make top-level
|
||||
build system; it can be used with any pre-extracted, properly patched
|
||||
set of source trees.
|
||||
|
||||
|
||||
Project scope and goals
|
||||
-----------------------
|
||||
|
||||
The primary goals of this project are to:
|
||||
|
||||
- Provide canonical musl support patches for GCC and binutils.
|
||||
|
||||
- Serve as a canonical example of how GCC should be built to target
|
||||
musl.
|
||||
|
||||
- Streamline the production of musl-targeting cross compilers so that
|
||||
musl users can easily produce musl-linked applications or bootstrap
|
||||
new systems using musl.
|
||||
|
||||
- Assist musl and toolchain developers in development and testing.
|
||||
|
||||
While the patches applied to GCC and binutils are all intended not to
|
||||
break non-musl configurations, musl-cross-make itself is specific to
|
||||
musl. Changes to add support for exotic target variants outside of
|
||||
what upstream musl supports are probably out-of-scope unless they are
|
||||
non-invasive. Changes to fix issues building musl-cross-make to run on
|
||||
non-Linux systems are well within scope as long as they are clean.
|
||||
|
||||
Most importantly, this is a side project to benefit musl and its
|
||||
users. It's not intended to be something high-maintenance or to divert
|
||||
development effort away from musl itself.
|
||||
|
||||
|
||||
Patches included
|
||||
----------------
|
||||
|
||||
In addition to canonical musl support patches for GCC,
|
||||
musl-cross-make's patch set provides:
|
||||
|
||||
- Static-linked PIE support
|
||||
- Addition of --enable-default-pie
|
||||
- Fixes for SH-specific bugs and bitrot in GCC
|
||||
- Support for J2 Core CPU target in GCC & binutils
|
||||
- SH/FDPIC ABI support

|
|||
|
||||
Some functionality (SH/FDPIC, and support for J2 specific features) is
|
||||
presently only available with gcc 5.2.0 and binutils 2.25.1.
|
||||
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
The build system make be configured by providing a config.mak file in
|
||||
the top-level directory. The only mandatory variable is TARGET, which
|
||||
should contain a gcc target tuple (such as sh2eb-linux-musl), but many
|
||||
more options are available. The top-level config.mak.dist file shows
|
||||
examples, and several full configurations are available in presets/*.
|
||||
|
||||
For recent gcc versions that need gmp/mpfr/mpc, suitable versions need
|
||||
to be installed in the default library path, or the appropriate --with
|
||||
configure options need to be added to GCC_CONFIG in config.mak so that
|
||||
the gcc configure process can find them.
|
||||
|
||||
After setting up config.mak, simply run make. Parallel builds are
|
||||
supported.
|
||||
|
||||
The resulting toolchain will be placed ./output by default, or the
|
||||
OUTPUT directory specified in config.mak. It is sysrooted and can be
|
||||
freely moved to a different location.
