Building without Solaris directory on Linux

[Frieder Berthold]

Hello to all,

I am new in buiding OpenJDK and hope, that this is the right list for my
problem.

To get a small JVM and rt.jar I try to build OpenJDK 8 with the small musl
libc (http://www.musl-libc.org/) instead of using the standard gnu libc,
yet I do not get it to build correctly.

My system: ubuntu 14.04 64bit

OpenJDK: OpenJDK 8 cloned from http://hg.openjdk.java.net/jdk8/jdk8/

My Problem: The following headers (which musl does not provide) cannot be
found while building the solaris-part


jdk8/jdk/src/solaris/native/java/net/PlainDatagramSocketImpl.c:38:24: fatal
error:        sys/sysctl.h: No such file or directory

and

           jdk8/jdk/src/solaris/native/java/net/NetworkInterface.c:50:25:
fatal error: bits/ioctls.h: No such file or directory

My Question: Even though I got a Linux (which is stated after the configure
process) it tries to build the sources in the solaris directory. Is this
necessary or is there a way to prevent this? Even deeper into this matter:
I only need the profile compact1 for the Linux OS, are there switches for
the configure step to achieve this?

Thank You in advance for any help!
Frieder
