RE: Trying to compile Octave on RHEL 7.3

[Michael L. Metts]

Thanks for getting back to me, Mike.  I'm definitely hoping to build and run 
Octave 4 and not the stuff that's in EPEL.  I understand that RHEL and Fedora 
have different bars (hurdles?) for what they will build and include ... 
although I can't understand why in this case since Octave 4 is more than a year 
old so it seems like it really should be in EPEL.

Yes, I am using whatever's in the hg repo.  Is that appropriate for what I'm 
doing?  What I'm doing, btw, is trying to get a clean stable Octave 4 running 
on RHEL 7.3 that doesn't have any broken features.  The ARPACK issue seems 
pretty bad to me.  Bad enough to not go forward.  The ARPACK and QScintilla 
issues have been frustrating since they're there but it can't find them or 
doesn't like them.   

Thanks for mentioning the log.  My software building skills are probably not 
that best.  I am motivated, though, we (at my firm) aren't that keen on the 
cost of Matlab.  I've used earlier versions of Octave on other platforms and 
really would like to get this going.  I appreciate the help.

The current version of Octave is 4.2.1, but it looks like you are building the 
development version from hg, is that right?

The best supported add-on repositories for CentOS / RHEL are the EPEL 
repositories, which it looks like you are already using. EPEL 7 contains a 
maintained package for Octave 3.8.2.

These are warnings, not errors, just to be precise. An error message would 
prevent you from continuing, these warn you that something may be disabled in 
the resulting build, but Octave will build and run.

You have both arpack-devel and qscintilla-devel installed, it's not clear from 
what you've shown why the libraries are not found, but config.log should give 
more details.

I can't help much with the sundials warning, version 2.7.0 should be new 
enough, but again config.log should give more details about what failed and 
why. It may be that the sundials package for EPEL / Fedora is not compiled with 
KLU support turned on.
