Re: Compiler bug pops up when compiling ghc-2.07 with 2.02

 I tried, but it seems to complete successfully. Nevertheless, later
 make all fails with the same message.
 Probably the dependencies generated by make boot (or make depend, for
 that matter) _are_ circular (citing from ghc/compiler/.depend):
 
 utils/FastString.o : basicTypes/Unique.hi
 
 basicTypes/Unique.o : utils/Pretty.hi
 
 utils/Pretty.o : utils/FastString.hi

My guess is that you have not got the line

Ghc2_0= YES

in your build.mk file.  GHC 2.x uses a different way of dealing with
mutual recursion (via M.hi-boot files) than GHC 0.29 (which used M.lhi files).

When you make that change to build.mk you'll need to do a make depend again.

Yes, this should be documented.

Remember, don't bother to use 2.06 or earlier for self-booting.  Only
2.07 is up to it.

 Hi, There,
 
 I am using GHC 2.06 for Win32 and why does GHC complain about "possibly 
 incomplete patterns"? Source file and error message are as follows. 
 Thanks.

Hi,
  I am in Glasgow for three months and my work is try to improve this 
warning messages, Just now the important word in the warning message
is "Possibly", ghc is not sure if the pattern is incomplete.

I hope to improve the situation before I return to Spain in 
the beginning of December ;)


Cheers, Juan.

...the circle closes :-( 

  BTW, mailing glasgow-haskell-bugs is probably a good idea with
  problems like these; I'm happy to help out, but I'm reading
  my e-mail infrequently at the moment.

   Thanks for this hint. I have downloaded binary version of 2.07 and
   tried again to recompile 2.07 with itself. However, after
   
   configure
   make boot
   
   make all fails like this:

   make[2]: Circular utils/Argv.o - utils/FastString.hi dependency dropped.
