[zoltrux@nettaxi.com (Juan Hernandez)]

Hello,

I am new in ada, I don�t know anybody who can help me with my problem,
excuse my poor english and  if the question is obvious...

I am trying to learn ada 95 with the book "Ada 95 Problem Solving and
Program Desing"   (Feldman & Koffman ) , I downloaded gnat Ada 95
compiler and when I try to execute compile, link and run the example
that came with the software I get the next error:


C:\GNAT307\GNAT307S\EXAMPLES>make
gcc -c -O2  hello.adb
gnatbl hello.ali
gcc.exe: installation problem, cannot exec `cpp': No such file or
directory (ENO
ENT)
make.exe: *** [hello] Error 4

Could you please help me to resolve this problem?
Any other suggestions are welcome.
Thanks in advance.

Juan
