Hi everyone, I tried to compile the Clang/LLVM toolchain from AOSP source a while ago and it looked like to be a very complex system (see my older post https://groups.google.com/forum/#!forum/android-building).
Now, I'm trying (again) to build Clang/LLVM toolchain... First, I saw this README <https://android.googlesource.com/platform/ndk/+/master/build/tools/> that mentions under "Building the toolchains" to execute "$NDK/build/tools/gen-platforms.sh --minimal". The minimal flags does not exist. Can someone confirm that this documentation is outdated? Then, I tried to follow another solution <https://hardenedlinux.github.io/toolchains/2016/04/01/How_to_build_Clang_toolchains_for_Android.html>. Despite the fact that it requires a crazy amount of dependencies, it seems to work. As my goal was to build a custom Clang (containing my own passes), I tried to merge it into external/llvm and external/clang... As if it were not complicated enough, the Clang/LLVM sources in the AOSP do not use CMake but use *.bp files (soong build system?) spread in every directory... I also ended up reading how the synching with official clang/llvm <https://android.googlesource.com/platform/external/clang/+/master/ToolchainPrebuilts.md> version is made. Questions: - Do we really need to use the "repo" tool and all those dependencies to only build the Clang toolchain? Any other "simple" solution (maybe CMake based)? - Where do the *.bp files come from? Do I need to update them manually after merging my Clang/LLVM version into external/clang and external/llvm? Or are they generated? - What I'm trying to achieve is nearly the same as what Google developers do when they incorporate an upstream version of Clang/LLVM. Does someone who has already done that could describe the steps needed? Many thanks for your help ! -- -- You received this message because you are subscribed to the "Android Building" mailing list.
