Hi, I wanted to try out hat debugger. I tried to install it according to instructions. I downloaded the source tgz and did following sequence of operations tar -xvzf hat-2.05.tar.gz cd hat-2.05 ./configure make it gives me following error! MkProg: hmake: the compiler 'ghc' is not known. Stop - hmake dependency error. I have following system configuration. ghc - Glasgow Haskell Compiler, Version 6.4.1, for Haskell 98, compiled by GHC version 6.4.1 hugs - Version: 20050308 hmake - version 3.10 (2005-03-11) gcc - gcc (GCC) 4.0.3 (Ubuntu 4.0.3-1ubuntu5) can anybody help me in this? Regards, Vikrant
