| + | ====== Distcc ====== | ||
| + | ===== Overview ===== | ||
| + | Distcc is used to compile packages faster on slow machines, such as [[Santo]] or the virtual machines, by doing some of the grunt work on physical hosts. | ||
| + | |||
| + | ===== Build Hosts ===== | ||
| + | * build0.sihnon.net ([[River]]) | ||
| + | * build1.sihnon.net ([[Badger]]) | ||
| + | * < | ||
| + | |||
| + | The build hosts use the following architectures: | ||
| + | |||
| + | {| class=" | ||
| + | |+ Architecture details | ||
| + | |- | ||
| + | ! Name | ||
| + | ! Value | ||
| + | |- | ||
| + | | **CHOST** | ||
| + | | x86_64-pc-linux-gnu | ||
| + | |- | ||
| + | | **gcc version** | ||
| + | | 4.4.2 | ||
| + | |} | ||
| + | |||
| + | The following cross-compilation environments are also available: | ||
| + | * i586-pc-linux-gnu | ||
| + | * i686-pc-linux-gnu | ||
| + | |||
| + | ===== Configuring a build host ===== | ||
| + | * Install {{Package|direct=yes|sys-devel/ | ||
| + | * Configure the distcc daemon to accept connections from local machines only | ||
| + | {{File|/ | ||
| + | |||
| + | </ | ||
| + | |||
| + | ==== Configuring a new cross-compilation environment ==== | ||
| + | Run the following command on each build host, where < | ||
| + | |||
| + | {{Root|< | ||
| + | crossdev -t i586 | ||
| + | </ | ||
| + | |||
| + | This command will build the necessary tools for cross-compilation, | ||
| + | * binutils | ||
| + | * linux-headers-quick | ||
| + | * glibc-headers | ||
| + | * gcc-stage1 | ||
| + | * linux-headers | ||
| + | * glibc | ||
| + | * gcc-stage2 | ||
| + | |||
| + | ===== Configuring a build client ===== | ||
| + | If the client has the same CHOST as all the build hosts, then setting up distcc is straightforward: | ||
| + | |||
| + | * Install {{Package|direct=yes|sys-devel/ | ||
| + | * Configure distcc to use each of the available build hosts with the following command: | ||
| + | {{Root|< | ||
| + | distcc-config --set-hosts " | ||
| + | </ | ||
| + | * Configure portage to use distcc for compilations by adding setting the following option: | ||
| + | {{File|/ | ||
| + | FEATURES=" | ||
| + | </ | ||
| + | |||
| + | ==== Configuring a build client with a different CHOST to the build hosts ==== | ||
| + | As explained in the Gentoo documentation, | ||
| + | |||
| + | * Create the wrapper script in < | ||
| + | {{File|/ | ||
| + | #!/bin/bash | ||
| + | exec / | ||
| + | </ | ||
| + | |||
| + | * Make the wrapper script executable, and replace the unqualified tool symlinks with symlinks to the new wrapper: | ||
| + | {{Root|< | ||
| + | cd / | ||
| + | chmod a+x i686-pc-linux-gnu-wrapper | ||
| + | rm cc gcc c++ g++ | ||
| + | ln -s i686-pc-linux-gnu-wrapper cc | ||
| + | ln -s i686-pc-linux-gnu-wrapper gcc | ||
| + | ln -s i686-pc-linux-gnu-wrapper c++ | ||
| + | ln -s i686-pc-linux-gnu-wrapper g++ | ||
| + | </ | ||
