[Octave-bug-tracker] [bug #48618] Image package: Warnings when installing ver 2.5.1. in dev branch

[Carnë Draug]

Follow-up Comment #10, bug #48618 (project octave):

See the following lines:


checking for mkoctfile... /usr/local/bin/mkoctfile
checking for octave... /usr/local/bin/octave
checking for g++ option to enable C++11 features... -std=gnu++11
checking whether xmin is in the octave::math namespace... no


It's failing to find octave::math::min for some reason which is why it
defaults to use xmin.  I think you have an older version of Octave installed
which comes first in the path.  If it was using Octave 4.1, the line about
C++11 features should come up as "none needed" because Octave 4.1 already
requires c++11. Instead it is adding the "-std=gnu++11" flag.

Is "/usr/local/bin/octave" really the Octave version of Octave with hg id
5e27d8d4e3c1 ?


This is what I get:


$ make all
cd src/ && ./configure
checking for a sed that does not truncate output... /bin/sed
checking for g++... g++
checking whether the C++ compiler works... yes
checking for C++ compiler default output file name... a.out
checking for suffix of executables... 
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether we are using the GNU C++ compiler... yes
checking whether g++ accepts -g... yes
checking for mkoctfile... /home/carandraug/.local/bin/mkoctfile
checking for octave... /home/carandraug/.local/bin/octave
checking for g++ -std=gnu++11 option to enable C++11 features... none needed
checking whether xmin is in the octave::math namespace... yes
checking whether templated lambda functions accept '&const int'... yes
configure: creating ./config.status
config.status: creating Makefile
config.status: creating config.h
config.status: config.h is unchanged
