Binutils Package ================ Interesting Patches ------------------- ld needs to be built with multiarch library directories in its list of search paths. Debian has [a patch][debian-ld-ma-patch] to which we can refer for this. Building the Binutils Package ----------------------------- If you want to temporarily change the targets for which Binutils is built, run the following commands before building: $ ./config clean $ PKG_TARGETS='list of architectures' ./config The default targets are listed in the `targets.in` file. To configure Binutils to be built for all default targets, run the following commands before building: $ ./config clean $ ./config Binutils Build System Mangling ------------------------------ [See `patches/01_pass-some-dirs-to-child-makes.patch` for some background information.] An alternative to `patches/01_pass-some-dirs-to-child-makes.patch` is to run make in each subdirectory ourselves instead of letting the top-level makefile do it for us. This way, we can leave the build system untouched and directly give each child make process the required macro settings. There are ten subdirectories in which we would need to run make (though of course we don't currently enable some of them, e.g. `gold`): * `bfd` * `opcodes` * `binutils` * `etc` * `gas` * `gold` * `gprof` * `intl` * `ld` * `libiberty` The disadvantage to this is a higher maintenance cost: we need to keep track of the subdirectories in which we need to run make. We need to watch out for changes to the dependencies of `install-host` and `install-target` in Binutils's Makefile.in (unlikely) and changes in the features (e.g. gold) we enable (likely). The trivial patch (which adds just three lines) should apply cleanly across Binutils releases, so it seems best to just stick with that.
