AOSP 8.1 failing to build on Mac High Sierra

Effie Barak

If you’re trying to build AOSP on Mac High Sierra and getting this (or a similar error):

[  0% 35/75651] yacc out/soong/.intermediates/system/tools/aidl/libaidl-common/darwin_x86_64_static/gen/yacc/system/tools/aidl/aidl_language_y.cpp

It means that bison isn’t working. If you try running bison by running this command for example:


it fails on error

Illegal instruction: 4

The solution to this is to fix bison, since it’s broken on High Sierra, by applying this patch from the folx at Mac Ports-

To apply this patch:

  • Navigate to the bison source directory at:

    cd external/bison

  • Save it as a plain text file as name.patch in the bison directory by coping the text and using

    pbpaste > patch-high-sierra.patch

(or any other way you’d prefer to save it)

  • Apply the patch to the source code (p level depends on which dir you’re currently in)

    patch -p0 < patch-high-sierra.patch

  • Navigate back on the root tree

    cd ../..

  • Make bison from source

    make bison

  • Copy bison from the bison directory from the out directory where AOSP is looking for it

    cp ./out/host/darwin-x86/obj/EXECUTABLES/bison_intermediates/bison ./prebuilts/misc/darwin-x86/bison/bison

And that’ll fix it! Now you can run the AOSP normally.
