Helo dear all, 
when I try to install anuga-viewer in ubuntu I have the following error after do "make"

collect2: error: ld returned 1 exit status
make[1]: ** [../bin/anuga_viewer] Erro 1
make[1]: Saindo do diretório `/home/regla/anuga-viewer/viewer'
make: ** [all] Erro 2

so I tryed by using "sudo ./ubuntu_gui_install.sh "

and I have other error:

Adding Anuga app files to the appropriate locations...
cp: impossível obter estado de “bin/anuga_viewer”: Arquivo ou diretório não encontrado

Complete! Anuga Viewer should now appear in your Applications list.

I have already looked into the  bin/ file and  there are not "anuga_viewer" archived in there, I think this archive is missing into the repository 

Can anybody help me, please?
