Bugzilla Bug 186372

A few weeks ago graphviz stopped emerge'ing for me.  I thought I'd wait a while
to see if subsequent "emerge --sync" cycles would clear it up.  Alas, no
improvement.  The error seems to be java-related.  I don't see any USE flags
dealing with java.

Reproducible: Always

Steps to Reproduce:
1. emerge -avuND graphviz
2.
3.

Actual Results:

You should post the output of emerge --info

Looks like the ebuild passes --disable-java explicitly to the configure script
so there should be no java built. My guess is some functionality triggered by
some USE flag pulls it. So you should also post output of 'emerge -pv graphviz'
so that we know what flags you are building it with.

# emerge -pv graphviz

These are the packages that would be merged, in order:

Calculating dependencies... done!

I'm getting the same error while compiling graphviz 2.12. To find out more
about this error, I downloaded the current stable version of graphviz from
their website (version 2.16) and tried compiling it myself. The weird thing is,
if I run configure with the --disable-java parameter, the build fails with the
"gv_java.cpp:138:17: error: jni.h: No such file or directory" message, just
like the gentoo ebuild. But if I _don't_ use the --disable-java parameter, the
build compiles just fine.

I should mention that I do have Java installed on my system. Maybe the
--disable-java parameter works incorrectly on systems with Java available. 

Anyway, I can see that this issue has also been filed for graphviz under bug
#1212: http://graphviz.org/bugs/b1212.html, so let's hope they'll fix it. In
the mean time the workaround for systems such as mine seems to be to enable
Java, not disable it. So can we please add a 'java' use flag to the graphviz
package and make the --disable-java parameter optional?

Try your luck w/ 2.16.1-r3 or later and report back... Thanks.

No change, both 2.16.1-r4 and 2.18 fail with the same error.

java USE-flag added to media-gfx/graphviz-2.18 - so this should be fixed.
