[Unattended] unattended lastest - compilation error

[Tharanga Abeyseela (RGA)]

Hi Guys,

I was trying to compile unattended latest source. (I downloaded it y'day). I changed the Makefile gcc to 2.5, and compile the source
Make iso, but finally got this error.

No shared library support; try without defining CC and CFLAGS

Thanks in advance
