Description Steven G. Kargl 2014-02-11 18:00:00 UTC 
On an up-tp-date FreeBSD-current,

% uname -a
FreeBSD troutmask.apl.washington.edu 11.0-CURRENT FreeBSD 11.0-CURRENT #0
r261721M: Mon Feb 10 13:05:20 PST 2014
kargl@troutmask.apl.washington.edu:/usr/obj

where all remnants of base gcc have been removed via 'make delete-old delete-old-libs'

Installation of octave and octave-forge-netcdf and octave-forge-octcdf leads to a 
clash of libc++ API.

% octave
octave:1> pkg load netcdf
octave:2> test_netcdf
error: import_netcdf: /usr/local/lib/octave/packages/netcdf-1.0.1/amd64-portbld-freebsd11.0-api-v49+/__netcdf__.oct: failed to load: /usr/local/lib/octave/packages/netcdf-1.0.1/amd64-portbld-freebsd11.0-api-v49+/__netcdf__.oct: Undefined symbol "_ZNK5ArrayISsE17resize_fill_valueEv"

error:   /usr/local/share/octave/packages/netcdf-1.0.1/test_netcdf.m at line 6, column 1

Clearly, _ZNK5ArrayISsE17resize_fill_valueEv is a name-mangled entity.  So, lets look at ldd output.

        libc.so.7 => /lib/libc.so.7 (0x2020bc000)

Whoops.  octave-forge-netcdf was built with /usr/local/bin/g++46.

How-To-Repeat: 
Install freebsd-current
Install octave
Install octave-forge-netcdf

From-To: freebsd-ports-bugs->tijl

I'll be committing a massive patch to all Fortran ports in a few days 
which should fix this.

Hi,

Can you check if this fixed after r344614?

Yes, r344614 seems to have fixed the problem.
After 'portmaster -r octave-3.8.0_1', I have

octave:1> pkg load netcdf
octave:2> test_netcdf
