Dia 0.90 on Solaris

[Dimitri Papadopoulos <papadopo REMOVE shfj DECOY cea fr>]

Hi,

I'm trying to build Dia 0.90 on Solaris. I get the following error:

        $ ./configure --prefix=/usr/local/dia-0.90 --with-libart-prefix=/usr/local/libart
        [...]
        Configuration:
                Source code location:   .
                Compiler:               cc
        
                Libart (AA rendering, png export):      yes
        
                Gnome support:                          no
                Build bonobo component (not supported): no
                Gnome-print support (not recommended):  no
        
                Python support:                         no
                (LIMITED) Freetype support:             no
        
        Unicode not present. This will NOT build.
        Now type make to build dia.
        $ 
        $ gmake

        $ 

What is this <unicode.h> file? Why is it needed? Could someone
help me work around this problem?
