Description

[Nevin Chen(Not active on Bugzilla)]

I got this error when I do a full build today.
I've run ./mach bootstrap succesfully.

Here's my mozconfig

ac_add_options --enable-application=mobile/android
ac_add_options --target=arm-linux-androideabi

ac_add_options --with-android-sdk="/Users/nechen/.mozbuild/android-sdk-macosx"
ac_add_options --with-android-ndk="/Users/nechen/.mozbuild/android-ndk-r15c"
mk_add_options MOZ_OBJDIR=./objdir-full-b04669e98

and error message:

0:07.47 ERROR: Could not find LLVM/Clang installation for compiling stylo build-time

froydnj: any thoughts?

What are the contents of ~/.mozbuild/?

I guess we need to start installing clang for Android bootstraps as well...if we haven't already.  Another option would be seeing if the NDK's clang could be used.  What happens if you do something like:

ac_add_options --with-libclang-path=/Users/nechen/.mozbuild/android-ndk-r15c/toolchains/llvm/prebuilt/linux-x86_64/lib64/
ac_add_options --with-clang-path=?Users/nechen/.mozbuild/android-ndk-r15c/toolchains/llvm/prebuilt/linux-x86_64/bin/clang

(I think those options are correct...)  Does that work?

Above works ( although I should use darwin-x86_64 since I'm on Mac)


But I got an error here:

You are now running into bug 1412983.  If you would try the patch stack in that bug, and see if that fixes things for you, that would be great!

I guess we can see about auto-detecting the NDK's clang for bindgen purposes.

this is fixed now
