[sane-devel] Install Erro

[Claude Sutton]

I am not able to install iscan.  I get the following errors in make and
make install.

I have installed with tar the front end and back end.

How can I fix this?

If we do not wish to lose our freedom, we must learn to tolerate our 
neighbor's right to freedom even though he might express that freedom
in a manner we consider to be eccentric.
