1 | For now, the shared libraries of Rust are private. |
| 2 | The rational is the following: | |
| 3 | * Upstream prefers static linking for now | |
| 4 | - https://github.com/rust-lang/rust/issues/10209 | |
| 5 | * rust is still under heavy development. As far as we know, there is | |
| 6 | no commitement from upstream to provide a stable ABI for now. | |
| 7 | Until we know more, we cannot take the chance to have Rust-built packages | |
| 8 | failing at each release of the compiler. | |
| 9 | * Static builds are working out of the box just fine | |
| 10 | * However, LD_LIBRARY_PATH has to be updated when -C prefer-dynamic is used | |

| 14 | Bootstrapping from nothing | |
| 15 | -------------------------- | |
| 16 | ||
| 36120449 SL |
17 | WARNING: This does not work for now as rust cannot bootstrap itself |

20 | You need a "stage0" rust compiler from somewhere. You can download a |
| 21 | pre-built minimal stage0 from http://www.rust-lang.org/ at build time, | |
| 22 | or use a rustc that was already in /usr/bin via whatever black magic | |
| 23 | (or some other path if you modify debian/rules). | |
| 24 | ||
| 120b4d47 | 25 | apt-get source --compile --build-profiles=dlstage0,nodoc rustc |
| 33384267 SL |
26 | |
| 27 | "dlstage0" downloads a stage0 from rust-lang.org during the build. | |
| 120b4d47 | 28 | "nodoc" disables building rust-doc package and skips the long list of |
| 33384267 SL |
29 | build-deps usually required. |
| 30 | ||
| 31 | dpkg -i rustc*.deb | |
| 32 | apt-get source --compile rustc | |
| 33 | ||
| 34 | This produces the full rust compiler built using your now obsolete | |
| 35 | "dlstage0" rustc compiler. | |
| 36 | ||
| 37 | Bootstrapping a new architecture | |
| 38 | -------------------------------- | |
| 39 | ||
| 40 | 0. Start with rust installed on an existing platform | |
| 41 | ||
| 42 | 1. Build a rust cross-compiler targeting new architecture | |
| 43 | ||
| 120b4d47 | 44 | sudo apt-get build-dep --build-profile=nodoc rustc |
| 33384267 SL |
45 | dpkg-buildpackage -t $new_arch |
| 46 | ||
| 47 | 2. Use cross-compiler to build a compiler that runs on new architecture | |
| 48 | ||
| 49 | dpkg --add-architecture $new_arch | |
| 50 | sudo apt-get build-dep --host-architecture=$new_arch rustc | |
| 51 | dpkg-buildpackage -a $new_arch | |
| 52 | ||
| 53 | # Perhaps this is sufficient ?? | |
| 54 | #apt-get source --compile --host-architecture=$new_arch rustc | |
