addendum to problem compilling 4.00/2

[edward barry jr]

Hey there !

Thought I supply some more info. on the problem.

If I compile ghc-4.00/2 with -O, it will compile hsc, but not
before setting several modules -Onot, and then fails to compile
PrelBase.

If I compile ghc-4.00/2 without -O, it compiles hsc, getting past
PrelBase,
but seems to think that PrelMaybe.hi is not a valid interface file,
needed by
PrelList.lhs where the compilation stops.

GHC-2.10 in incompatable with the build as there is no PrelArr needed by

something in the compiler(I looked, but forget which).

The following are the warnings I get from building the compiler. I not
sure
it will help to find where the problem lies within the compiler.

Later
Ed

Problem compiling ghc4.00/2

[edward barry jr]

Hey there;

The following problem occurred while compiling GHC-4.00/2
on a Linux platform, using ghc-3.02(apr.14 version) and gcc2.7.2.3

Any idea what it means when the compiler can not find the suitable *.hi
file. It is physically there. Viewing PrelMaybe.hi shows no apparent
inconsistencies.

Thanks
Ed Barry

How to read .hc files

[edward barry jr]

Hi All;

I seem to recall seeing some documentation on how to read/interpret
generated .hc files.
Simon M. suggested that perhaps I meant how to read a simple dump, but I
thought
the references I am referring to were specific to .hc files.

Any help, where I might have encountered this??

Thanks!!
Ed Barry
