RE: Question for successful Cygwin/gcc builders

["Dockeen" <dockeen at mchsi dot com>]

Actually, someone did report a successful build when in fact,
they could not even compile a simple program with the resulting
g++ or g77.

Let me ask you this directly, do you use the gcc you just
built to do anything?  Do you have favorite work tools that
you compile to see if they work?  That is what first tipped
me off that I was not in fact succeeding.  The program I work
on every day, which compiles fine on base gcc, will not come
close to linking under the new gcc.  I'm not talking about
little things, I'm talking about not being able to find
new and delete.  So I went back to some classic simple stuff.
The old hello world programs we do a million times.  They
won't compile either.

The other point that no-one has talked about is the environment.
There are different ways to install Cygwin.  Cygwin can be customized.
All Cygwin environments are not equal, so saying things will work
under Cygwin is not complete.

Judging by Janice's recent posts, I think I am not alone in
being concerned about what is a successful build.

I noticed by the way that you only hinted at things that you have
to do to make things work, have any secrets you would care to
share?

Have you checked the results submitted to gcc-testsuite?  Most of the
'make -k check' failures are due to not finding all necessary
modifications to the cygwin dejagnu setup, although there is one minor
modification to objc required to get it to run.  If you are
trying to run SSE, you must deal with the alignment parameter in binutils
bfd/coff-i386.c, but it reads like you are chasing after
something else.

The libraries in i686-pc-cygwin have to be blown away before re-building,
but that's not unique to cygwin.

How could anyone claim a successful build if they didn't make it through
stage 3 and the libraries for the chosen languages?  That
implies quite a bit of compiling using the new compiler.
