For now, the shared libraries of Rust are private.
|
|
The rational is the following:
|
|
* Upstream prefers static linking for now
|
|
- https://github.com/rust-lang/rust/issues/10209
|
|
* rust is still under heavy development. As far as we know, there is
|
|
no commitement from upstream to provide a stable ABI for now.
|
|
Until we know more, we cannot take the chance to have Rust-built packages
|
|
failing at each release of the compiler.
|
|
* Static builds are working out of the box just fine
|
|
* However, LD_LIBRARY_PATH has to be updated when -C prefer-dynamic is used

Bootstrapping from nothing
|
|
--------------------------
|
|
|
|
WARNING: This does not work for now as rust cannot bootstrap itself
|
|
|
|
|
|
You need a "stage0" rust compiler from somewhere. You can download a
|
|
pre-built minimal stage0 from http://www.rust-lang.org/ at build time,
|
|
or use a rustc that was already in /usr/bin via whatever black magic
|
|
(or some other path if you modify debian/rules).
|
|
|
|
apt-get source --compile --build-profiles=dlstage0,nodoc rustc
|
|
|
|
"dlstage0" downloads a stage0 from rust-lang.org during the build.
|
|
"nodoc" disables building rust-doc package and skips the long list of
|
|
build-deps usually required.
|
|
|
|
dpkg -i rustc*.deb
|
|
apt-get source --compile rustc
|
|
|
|
This produces the full rust compiler built using your now obsolete
|
|
"dlstage0" rustc compiler.
|
|
|
|
Bootstrapping a new architecture
|
|
--------------------------------
|
|
|
|
0. Start with rust installed on an existing platform
|
|
|
|
1. Build a rust cross-compiler targeting new architecture
|
|
|
|
sudo apt-get build-dep --build-profile=nodoc rustc
|
|
dpkg-buildpackage -t $new_arch
|
|
|
|
2. Use cross-compiler to build a compiler that runs on new architecture
|
|
|
|
dpkg --add-architecture $new_arch
|
|
sudo apt-get build-dep --host-architecture=$new_arch rustc
|
|
dpkg-buildpackage -a $new_arch
|
|
|
|
# Perhaps this is sufficient ??
|
|
#apt-get source --compile --host-architecture=$new_arch rustc
