** Description changed: + Stable release update justification: + + Impact: Missing symbols mean that Octave's fltk plotting backend is broken. + Development branch: Fixed by removing unnecessary build-dependencies on libgl1-mesa-swx11-dev and libglu1-mesa-dev, which between them (probably mainly the first one) cause configure to fail to detect a working OpenGL installation. + Patch: http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/natty/octave3.2/natty/revision/12 backports easily (changes to debian/in/control and debian/control). + TEST CASE: Run octave3.2, then type (without the outer single quotes) 'backend("fltk")' followed by 'sombrero'. You should see a coloured plot resembling a sombrero hat. + Regression potential: I imagine it's worth trying some of Octave's other example programs. + + Original report follows: + Binary package hint: octave3.2 Steps to reproduce: run octave3.2 backend("fltk") Expected outcome: prompt should return and the fltk backend should be usable for plotting. Outcome: error: /usr/lib/octave/3.2.3/oct/x86_64-pc-linux-gnu/fltk_backend.oct: undefined symbol: _ZTV15opengl_renderer error: called from: error: /usr/share/octave/3.2.3/m/plot/backend.m at line 56, column 5 Solution: While compiling octave3.2, ftgl-dev is one of the dependencies. If ftgl-dev is installed while compiling, this error will not happen. Thanks.
