I've got a gcc4.5.2 (by the way, even if it's ambiguous for a given

Je pourrai tester sous ma fedora core 15 avec gcc 4.6.
A voir si j'ai encore ma fedora 14...
Sinon, j'ai rien d'autre sous la main... pour le moment.

Mais ok, je note.

Is there any library libboost_program_options-* compiled in your system ?

[mtola]

yes, that's why I don't understand...

[mtola]

ps: see issue 72 for this problem (not this one)

[mtola]

Ok, no warning for me with gcc (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2 under Ubuntu 11.04 - 32 but I fix the source, see my commit here: https://github.com/mtola/DGtal/commit/ded4f649afb90e7df3772f64855d7c1ad633c1b6
