Apple uses `clang` extensively for development and has upstreamed the necessary functionality so that a vanilla clang can take advantage. It supports the use of `-F`, `-target`, `-mmacosx-version-min`, and `-isysroot`, which are all necessary when building for macOS. -Apple's version of `binutils` (called `cctools`) contains lots of functionality missing in the -FSF's `binutils`. In addition to extra linker options for frameworks and sysroots, several -other tools are needed as well. These do not build under Linux, so they have been patched to -do so. The work here was used as a starting point: [mingwandroid/toolchain4](https://github.com/mingwandroid/toolchain4). - -In order to build a working toolchain, the following source packages are needed from -Apple: `cctools`, `dyld`, and `ld64`. - These tools inject timestamps by default, which produce non-deterministic binaries. The `ZERO_AR_DATE` environment variable is used to disable that. -This version of `cctools` has been patched to use the current version of `clang`'s headers -and its `libLTO.so` rather than those from `llvmgcc`, as it was originally done in `toolchain4`. - To complicate things further, all builds must target an Apple SDK. These SDKs are free to download, but not redistributable. See the SDK Extraction notes above for how to obtain it. |
