# Builds the toolchain the Quest app carries so a player can build the game on the headset

# ("Build on this Quest"), without a PC:
|
|
#
|
|
# * translator/ the WiiCompiled translator published for linux-bionic-arm64 (.NET 10, which runs
|
|
# it on Mono), started through translator_host (android/toolchain/translator_host.c);
|
|
# * llvm/ Termux's Android build of clang and lld 21.1.8 with exactly the shared libraries
|
|
# they load, OpenSSL for the translator's hashing (Android only has BoringSSL), and
|
|
# clang's own builtin headers;
|
|
# * ndk.json the Android NDK files a build also needs (the aarch64 sysroot, libunwind, libatomic,
|
|
# compiler-rt builtins). The NDK is Google's to distribute, so the headset downloads
|
|
# them from dl.google.com with HTTP range requests (about 8 MB of the 784 MB zip) and
|
|
# checks each file against the SHA-256 recorded here;
|
|
# * toolchain.json every file of translator/ and llvm/ with its SHA-256, and the fingerprint over
|
|
# them. Those two directories travel packed in files.zip.
