Re: [Texmacs-dev] Qt TeXmacs-1.0.7.7, Qt-4.6.3 compilation error

[Gubinelli Massimiliano]

Dear Andrey,
 I cannot check at the moment the reason for these compilation errors. I will 
have to install Gentoo or at least ImLib2 on my Mac. Please note that 
TeXmacs/Qt do not need ImLib2 to work, so as an option you can disable ImLib2 
support (--with-imlib2=no). I think this will solve your problem.
In any case I will have to dig further on the problem.

Thanks
Best
max
