[llvm-dev] Help Building LLVM for Android

Hey Guys,

I'm working on a project in Android related to System-level Audio DSP
Effects for Tuning Android Audio.  I want to leverage Faust (
https://faust.grame.fr/) to allow users to program their own filters.
Faust provides a libfaust implementation which includes a JIT Compiler
which leverages LLVM and seems to be the best path for me to use.
Unfortunately I'm having problems cross-compiling LLVM for Android on my
Windows Dev machine.  Wondering if anyone has any advice for me?

I've been trying to use the android-ndk cmake & toolchains to build LLVM
so
that I can cross-compile Faust against the Android LLVM build.  I've
managed to get Android's cmake to generate an Android Gradle Ninja project,
but when I try to build it I get lots of errors that seem to indicate that
the Ninja project is invalid, such as the following errors :

I'm kinda stumped as to what's going on...

[llvm-dev] Help Building LLVM for Android

Although there didn't seem to be any interest in my thread, I figured I
should still update with my partial success.  I've managed to get LLVM to
build with Android NDK and have put together scripts to encapsulate the
necessary commands.  See https://github.com/Jman420/llvm_for_android for
scripts and instructions.

For some reason the '*.exports' files do not seem to get generated
correctly.  They end up with double quoted lines (such as '"LLVM
{"') which
seem to be invalid format.  Unfortunately, I haven't been able to figure
out where/what generates those files.  They seem to be generated by the
actual compiler since those files don't exist until I execute
'cmake --build . --target install'.
