tl;dr I have had problems building JDK9 due to -Werror=format flag on gcc/g++ 4.8.2
and also due to hotspot/agent/src/os/linux/libproc.h including
linux/ptrace.h instead of sys/ptrace.h


I have been trying to build JDK9 from
http://hg.openjdk.java.net/jdk9/dev (or /hs-comp or /jdk9) and JDK8u
from http://hg.openjdk.java.net/jdk8u/jdk8u/

First, I'm seeing the following on JDK9 only:

Pasted at http://fpaste.org/110642/30430021/ (and there are many many lines with
similar errors until the build is aborted).

After ignoring the error ('CFLAGS="-Wno-error=format" make' or editing
make/linux/makefiles/gcc.make to remove "-Werror=format"), I get the
following on JDK9:

For JDK8 see: http://fpaste.org/110638/40304229/

I see that both sys/ptrace.h and linux/ptrace.h have been included:

$ grep -r ptrace.h hotspot/
hotspot/agent/src/os/linux/ps_proc.c:#include <sys/ptrace.h>
hotspot/agent/src/os/linux/libproc.h:#include <linux/ptrace.h>

Usually linux/ptrace.h is used by glibc to do syscall, wile sys/ptrace.h
is used by app code to do library calls (thanks Maynard for the info).

After editing hotspot/agent/src/os/linux/libproc.h to use sys/ptrace.h
I'm able to build both JDK8 & JDK9.

Some settings:

JDK8 configure:
$ ./configure \
  --with-boot-jdk=/home/tdaitx/icedtea7/openjdk.build/j2sdk-image/ \
  --with-jvm-variants=server --with-jvm-interpreter=cpp \
  --with-extra-cflags=-Wno-strict-aliasing

JDK9 configure is similar but I point it to a JDK8 build.

Make for JDK8 and JDK9:
$ make JOBS=8 LOG=debug
