Problems compiling on 64 bit

[Paolo Redaelli]

I've encountering some problems compiling SE both snapshots and svn on
my new 64-bit ubuntu intrepid.
I attack here the logs.
The very same tarball compiled on a 32bit box work out-of-the-box.
Packing this installation and moving it into the 64 bit machine provides
an usable enviroment but I wasn't able to compile it on 64bit.
Thanks in advance for your attention..

I have no issue compiling both 2.3 and latest svn on my x86_64 Fedora
10. The only patch indeed is linked to gcc 4.3 that not allows to
compile SmartEiffel C code with -O2 or -O3.

Thanks for the hint. I'm not sure but it seems to me I was using the
same version of gcc on both machines. Tomorrow I will check as I cannot
access the other machine right now.

I know there are problems with modern 64 linux releases, but I'm
convinced it's more gcc related problem (note that it can be valid
optimisation applied on tricky C code) that pure 64 problem.

It's my third point on my todo list (first one is eiffeltest).

I was able to compile a 64bit version from SVN patching the various
building scripts, actually removing any optimization. I can send you a
diff file this evening if you want (I haven't access to that box right
now).

A long-term option is to turn SmartEiffel into a proper gcc front-end
or to use the compiler infrastructure provided by llvm.org.

Low-level classes to access all the various C functions and structure
could be generated with the (almost finished) eiffel-gcc-xml
(http://svn.gna.org/viewcvs/eiffel-libraries/trunk/tools/)

Thanks for your efforts,
