Make: *** No rule to make target ...rs_core_math.rsh

[Oyewale Oyediran]

I'm building AOSP from source. I have followed all the instructions from source.android.com. I have extracted the vendor binaries
But running 'make' ends with the error below.

I have tried various build configurations (aosp_hammerhead-userdebug, full_hammerhead-userdebug) and I get the same error.

Thanks

No rule to make target usually means that you are missing the file. Go to frameworks/rs/scriptc and see if you have rs_core_math.rsh.

Thanks Stefan.

It worked.

I was working on the android-4.4_r1 branch

It seems the frameworks/rs/scriptc/rs_core_math.rsh file was missing from the branch

I had to clone the repo https://android.googlesource.com/platform/frameworks/rs/+/master and copied out the rs_core_math.rsh and copied it into the frameworks/rs/scriptc/ directory.

I ran 'make clean' before running a build, and it worked.

Thanks
