.mozconfig contains:
# Build Firefox for Android:
ac_add_options --enable-application=mobile/android
ac_add_options --target=arm-linux-androideabi

# With the following Android SDK and NDK:
ac_add_options --with-android-sdk="/home/jyavenard/.mozbuild/android-sdk-linux"
ac_add_options --with-android-ndk="/home/jyavenard/.mozbuild/android-ndk-r15c"

Occurs after clobber.

Using Ubuntu 17.10

this should have been fixed with bug 1412734.

it didn't for me

ok..

./mach clobber wasn't sufficient.

after clobber there was still:
$ ls -l ../obj-ffandroid-dbg/.mozbuild/
build_resources.json  last_log.json         warnings.jso

After deleting OBJDIR it compiles fine...

This doesn't make much sense to me; I can't see what effect those files would have on what sort of linker detection we were doing...gps, is there some reason that these files can't live at the toplevel, or at least in a place where the clobberer would remove them by default?

I doesn't make much sense to me either...
I had run multiple ./mach clobber , deleting the gold directory and so forth and compilation always failed in the same manner.

Only after deleted $OBJDIR that it did compile..

very puzzling

`mach clobber` retains .mozbuild and msvc directories. It is possible some file in .mozbuild is interfering somehow.

can no longer reproduce...
