Hi Per,
the SE stuff should already be handled by the Make process (as pointed
out by Andrew). However I think the detection of SELinux is quite
fragile, I also had problems with it in the past. In the build log you
should see something like:
\
rm -f libjvm.so.1; ln -s libjvm.so libjvm.so.1;
\
[ -f libjvm_g.so ] || { ln -s libjvm.so libjvm_g.so; ln -s
libjvm.so.1 libjvm_g.so.1; };
\
if [ \"\" = \"\" ] ; then \
if [ -x /usr/sbin/selinuxenabled ] ; then \
/usr/sbin/selinuxenabled; \
if [ $? = 0 ] ; then \
/usr/bin/chcon -t textrel_shlib_t libjvm.so; \
if [ $? != 0 ]; then \
echo "ERROR: Cannot chcon libjvm.so";
\
fi \
fi \
fi \
fi \
}
Linking vm...
If this fails, you'll have to work around it manually.
Regarding the HPI-problem I only have a wild guess. Recently there was
a change which removed HPI (see:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6348631). So
perhaps this interferes with your build JDK which is quite old as far
as I saw ("1.6.0-rc-b104"). Perhaps building with a newer Java 6
version or even Java 7 may solve the problem.
Regards,
Volker
