How can I compile octave 3.4.2 with fltk support, under Ubuntu 11.04 64


with no success so far. I have the necessary dependencies installed, in
particular the ubuntu package libfltk1.1-dev.

Otherwise compilation works well.

Thank you very much,


libfltk1.1-dev is for sure not enough, it is awhile ago I tested building
3.4 on a ubuntu (I am an openSUSE user) but the simplest way to ensure
that the dependencies are met is to install the build dependencies for
3.2 first.

sudo apt-get build-dep octave3.2

and run ./configure (you should not need any switches here) afterwards.
If it does not help can you post the configure log, I can at least check
for you what you need in a virtual machine if no ubuntu user jumps in

I already installed all build-dep for octave3.2. I attach the
(compressed) config.log after doing ./configure.

Thank you very much,


Can you tell in detail what does not work. From your configure log file I have
to conclude that it should work. You also say your compile goes well, so when
does an error happen and what is the error?

I found no error in compilation, but when I run Octave I get:

octave:1> version
ans = 3.4.2
octave:2> available_graphics_toolkits
ans =
  [1,1] = gnuplot
octave:3> graphics_toolkit("gnuplot")
octave:4> graphics_toolkit("fltk")
error: feval: /usr/local/lib/octave/3.4.2/oct/x86_64-unknown-linux-gnu/__init_fltk__.oct: failed to load: /usr/local/lib/octave/3.4.2/oct/x86_64-unknown-linux-gnu/__init_fltk__.oct: undefined symbol: _ZN9Fl_Window5flushEv
error: called from:

Besides that Octave works perfectly

Thank you once more,
