Good Afternoon Alexander

Many thanks for your prompt and comprehensive feedback. 

Apple has provided an installer which includes both the JRE and JDK for 1.6. I 
guess I could install that and then delete the JRE.

Or, as you indicated I could disable dependence on Java altogether.

Ebrahim

Oops, no this would not work because octave also has a runtime dependence on 
Java1.6

[Fink-users] Updating octave requires legacy java

2016-02-11 Thread Ebrahim Mayat 
Dear all

I am unable to update octave382-atlas on 10.11.3:

$ fink update octave382-atlas
Information about 8986 packages read in 1 seconds.
The package 'octave382-atlas' will be built and installed.
Reading build dependency for octave-atlas-3.8.2-10...
WARNING: While resolving dependency "system-java16-dev" for package 
"octave-atlas-3.8.2-10", package "system-java16-dev" was not found.

I do not wish to install java1.6.0 on El Capitan since Oracle has advised 
against using legacy Java due to security loopholes. Would it be possible to 
make octave depend on java1.8.0 instead ?

Thanks in advance,
Ebrahim

Not easily.  

1)  Octave _links_ to a Java library, even though that isn’t a best practice.  
The default linkage for OS X in their build is to the legacy Java 1.6 framework.
2)  Oracle decided not to provided an unversioned convenience symlink for their 
Java releases to point at the current version, and Fink doesn’t currently have 
such a thing, so it’s nontrivial to come up with a scheme which will work with 
everybody’s Java setup.  The legacy Java 1.6 has a stable location.

Multiple Java versions coexist, and you’ll only be using a library from Apple’s 
Java 1.6.  Anything else you do with Java should use the current Oracle version 
on your system.

Or feel free to modify your build by copying octave-3.8.2.info and the relevant 
octave*.patch files to /sw/fink/dists/local/main/finkinfo, and add .1 to the 
Revision in octave-3.8.2.info.  The easiest thing to do is to add 
--disable-java to the ConfigureParams to disable Java, and then you can remove 
system-java16 and system-java16-dev from the dependencies.
