[k-okada]

it passed on travis, so wich compiler are you using?
https://travis-ci.org/jsk-ros-pkg/jsk_3rdparty/jobs/91743953

[wkentaro]

gcc? https://gist.github.com/wkentaro/bab6aaa8124462f9804a#file-nlopt_build_log-txt-L58

[s-noda]

[nlopt] static int struct_val_default(Octave_map &m, const std::string& k,

I think this line means that octave is missing.
So, could you find octave directory under the 3rdparty/nlopt/build/nlopt-x.x ?
If not, remove build dir, and try to build again?

[wkentaro]

need to extract nlopt-x.x.tgz manually?

https://gist.github.com/wkentaro/475816be9008f395ccf2

[wkentaro]

I tried but had error.

[s-noda]

I believe no.

In your environment, octave is installed?
nlopt seems to depend on octave, but there might be no installation of octave.

I think sudo aptitude install octave is ok.

[wkentaro]

octave is installed

% dpkg --get-selections | grep octave
liboctave-dev                   install
liboctave2:amd64                deinstall
liboctave3:amd64                install
octave                      install
octave-common                   install

I also reinstalled these.

[wkentaro]

this happens on my laptop and desktop pc.

# desktop
% dpkg --get-selections | grep octave
liboctave-dev                   install
liboctave3:amd64                install
octave                      install
octave-common                   install

[s-noda]

I have only hydro environment.
In my environments, this octave dir is dummy compiled.

I'm not confident, but,
this octave compile is switched by using some system environment variables such as WITH_OCTAVE_TRUE, OCT_INSTALL_DIR,,, in configure script of nlopt.

In my environment, env | grep OCT is empty.

[wkentaro]

I think why travis test passes is that there is no octave compilation on it. (It can detect octave installation)

Mine also.

[wkentaro]

I think why travis test passes is that there is no octave compilation on it. (It can detect octave installation)

the error disappears after removing octave from environment.

sudo aptitude purge octave

[wkentaro]

If no one is using nlopt on indigo. ( I'm not using it )
We can skip nlopt at build time with some changes on CMakeLists.txt.

[s-noda]

great!

We can skip nlopt at build time with some changes on CMakeLists.txt.

I think it's ok, but, please check the following diff?
I think this option --without-octave skip the octave compile.

[wkentaro]

That fixed the problem.

[s-noda]

Thanks.

I believe this update has no effect on my programs
because this octave option seems to compile the octave wrapper of nlopt
and this wrapper has no user in JSK.

[k-okada]

thanks!!!! @wkentaro @s-noda
