1.7.0 incompatible with Octave >= 5.0.0

[dvzrv]

The current latest stable release (1.7.0) is incompatible with the current Octave version (5.1.0).

[flatmax]

Any ideas what has changed ?

@flatmax - argh, there are piles and piles of warnings against 5.1.0, but the only important message is buried in the middle:

$ make 2>&1 | grep error
Octave.C:46:21: error: default argument given for parameter 2 of ‘octave_value get_global_value(const string&, bool)’ [-fpermissive]

The important message is right at the beginning:

Octave.C:46:21: error: default argument given for parameter 2 of ‘octave_value get_global_value(const string&, bool)’ [-fpermissive]
   46 | extern octave_value get_global_value (const string& nm, bool silent = false);

Since the function prototype is declared in octave's header, there is really no need to have that "extern" line. Just deleting it works.

[HinTak]

In the middle of the configure, there is also a message:

warning: LFLAGS is deprecated and will be removed in a future version of Octave, use LDFLAGS instead
checking for /usr/include/octave-5.1.0/octave/../octave/octave.h... yes

Anyway, I was able to get past octave related errors, by doing two things:

• delete the "extern octave_value get_global_value ..." line in src/Octave.C line 46

• setting LDFLAGS to find where octave's libraries are:

LDFLAGS=-L`octave-config -p OCTLIBDIR` ./configure

I am having a lot of other problems finding the other libraries though, but octave related errors are gone.

It appears I am just one step away from finishing:

The linking seems to be the order of the command line arguments, you need to have -L before all the -l's .

[HinTak]

Argh, I have fixed the library issue - your autoconf script is a bit screwy. Anyway, the octave issue is as above.
