Re: Compiling GCC under Cygwin

[Arjen Markus <arjen dot markus895 at gmail dot com>]

Hi Angelo,

true, it is not Fortran-specific. I used this mailing-list because I
am familiar with it and because
the purpose of this attempt was to see if I can in some way contribute
other things than
bug reports ;).

The error you refer to is actually an error in the C source, whereas
the build error I got
has something to do with the Makefiles.

As for the build experiment itself:
- I downloaded the 4.8.1 source
- I configured the Makefiles with this command:
 ./configure --prefix=d:/gcc-src/gcc
- Then I ran make and the error message I reported before.

(It is not impossible that the error is a consequence of the
permission errors I got
before - they are not completely gone yet, as they re-surfaced in
another project.)

If I understand the issue correctly, I can probably get rid of it
tomorrow - as then the
laptop will be connected to the proper domain.

Anyway. thanks for the reaction. I will see if I can analyse it further.

Regards,

Arjen
