[Alejandro F Frangi]

Hi,

 Is there any fool-proof document/guidelines explaining how
to use egcs to do simple things like

 - generating a shared library
 - generating a static library

 from different modules that contain (instantiations of)
templated classes. I am specially interested in knowing
which flags should be used to avoid unresolved symbols in
the final library.


 I would also like to know the flags to link several
(static/shared) libraries with an executable in order to
avoid soe strange warning messages like 

   ld: WARNING 85: definition of AString::operator=(AString
const &)in AString.o preempts that definition in
/hosts/hydra/data1/alex/src/COOOL-1.3/lib/libcoool.so.


 Thanks for the patience with this beginner...

 Regards,

        Alex

You haven't given much information but as your question is about using
GCC (not developing it) you might get a better answer by mailing
gcc-help@gcc.gnu.org

The gcc@gcc.gnu.org list is for GCC development.

You will need changes to some configure files to add your target tuple, 
e.g. config.sub, config.gcc, etc.  Most of the work will be adding the 
gcc backend target files in config/target, you will need a .h, .c, and a 
.md file at a minimum.  You will also need some library changes, there 
are some target dependent parts of libstdc++ for instance.

There is extensive documentation available.  See the gcc/doc directory 
in the sources, or see the web site.  This isn't very readable, and it 
doesn't tell you how to do a port, but it has valuable info you will need.

The easiest way to start a port is probably to look at an existing port 
for a target that is similar to yours, and then pattern your port after it.

Hi,

Could you help me in configuring GCC to use as a cross compiler for Linux on windows. To be precise i want to compile my programs on windows using GCC and execute it on Linux machine.

I have downloaded cygwin and used the configure script to configure GCC to compile my windows program and tried to execute it on Linux , it says cannot execute binary file. Could you please help me on this.

Regards
Brajesh

See http://www.cygwin.com/ and http://www.mingw.org/ -- both provide
GNU Fortran 77 compilers that will run on Windows 2000, but with very
different runtime behaviour. Mingw site has a short description on
the difference between the two.

GNU Fortran 77 runtime library provides SYSTEM, which you can use. You'll
have to read the runtime library documentation for that.

Hi

My name is Satya
I am a graduate student at the Univ of Minnesota

First of all let me thank you for the g77 compiler.
I work in Windows 2000.

I have a question on the Fortran Language.

How can we call an external executable (DOS - exe file) inside a Fortran
program? 

Is it possible? Are there alternatives to it?

Thank you
satya

Wrong list.  Try the binutils list.  as and ld are both part of binutils.

Nicely.  For more information, I'd recommend reading the source.  :-)

Hello,

If I ask the wrong list please excuse and try to point  me to the right
direction.

I want to know how  gcc assembler and ld cooperates in order to build an
object file ( in special an ELF object file ).

I want to know how the symbol table is built and all other things
related to an object file.

Thanks,

NIcu

Well, optimizing gcc's memory allocation should be an intersting
project.  Certainly we do little in this area, so any improvement you
could contribute would be great.  Also, with the advent of 200+ cycle
memory misses, it might be fairly profitable.  As for register
allocation, I would hope that it would be hard to improve gcc's
scheme, but the right peron with the right algorithm...

> schemes for a specific architecture (Motorola's SC100 family).

Our code isn't specific to any processor and any code you submit that
we included, would have to be fairly machine independent, or at least,
it would have to not harm performance on other machines.

You should not count on us providing you with much, other than what
you can get with ftp and the web.  All that, you can find via our web
site.  We are more likely to answer a very specific and details
question, than a question like, so, how does this thing work?

> something that would be helpful (like the e-mail address of someone

We don't provide email addresses of anyone.  You already have _the_
email address.

You already know the list.  See our website for details on subscribing
(gcc.gnu.org).

It's probably be best if you post whatever questions you have directly
to the mailing list, so that more people can help.

     I am a student at "Politehnica" University Bucharest and my graduation 
project is to optimize the memory and register allocation schemes for a 
specific architecture (Motorola's SC100 family). I have been given a machine 
description for this architecture.

    I saw at www.gnu.org that you encourage people to write you, and so I 
wrote you this message, hoping that you can provide me something that would 
be helpful (like the e-mail address of someone willing to answer some of my
