Make Failed

[Sparse Way]

Hi,
I am building openjdk for android arm using Ubuntu 64 bit, andoid-ndk-r13b
Followed the guide at the official page (seems outdated) and applied the workarounds from mailing http://mail.openjdk.java.net/pipermail/mobile-dev/2018-August.txt since encountered same issues.

  1.  android-ndk-r13b doesn't have dependencies needed to make openjdk like sys/signal.h and types.h, even though i found them in /usr/include but for some reason make cannot find them.
  2.  Linking them using "ln -s" doesn't completely help either; make hotspot problem was fixed but ended having this error:
