Compilation error : gfxFT2Fonts.cpp

[kakashizilla]

Hello,
I'm trying to build icecat in Fedora 11 and I've got the following error :
>gfxFT2Fonts.cpp: In constructor ‘gfxFT2FontGroup::gfxFT2FontGroup(const
> nsAString_internal&, const gfxFontStyle*)’: gfxFT2Fonts.cpp:241: erreur: no

Does somebody have an idea of how to fix it ?
What are the standard option to add to successfully build icecat ?

Thanks !
