Support in gcc for 586

Support in gcc for 586

[Nicolay Giraldo]

I just downloaded and installed cygwin, to find that I can't compile anything because gcc supports only 686 and up.
I have a Pentium MMX, what can I do ??

Use the gcc that comes with the package.

It should support 386+.

Humm.. I just checked my gcc.

flognat@CUTIE2K /usr/lib/gcc-lib
$ gcc --version
2.95.3-2
flognat@CUTIE2K /usr/lib/gcc-lib
$ ls /usr/lib/gcc-lib/
i686-pc-cygwin

Smells like 686 compiled??

No!!! It was built on i686 not optimized for i686.  The default
configuration is for i386 optimization.  However, the autoconfiguration
sees the arch as i686 if you configure on i686 and sees the arch as i586
if you configure on a i586, etc.

Did you actually TRY THIS?

Cygwin was built with this compiler.  I haven't seen anyone complaining
that Cygwin didn't operate on a "Pentium MMX".

If you are actually having some sort of problem, then post it here.
Otherwise, it appears that you are making incorrect assumptions about
the way that gcc operates.

Sorry, I assumed that the subdir in /usr/lib/gcc-lib indicated the
_target_ that gcc was built _for_. (like if you built a cross-compiler
for m68k on a 686, where should it be placed?)

I can test it on an old 586 later on today, and back off..

Yep, installed latest cygwin on an old 586, and gcc seemed to work,
sorry for threading on areas I don't know about.

Could it be something like gcc 2.95.3-3 requires cygwin 1.1.8??

Windows Spanish version:
El archivo CPP0.EXE está vinculado a un CYGWIN1.DLL:getrlimit de exportación
que no existe.

Using GCC 2.95.3-3 and Cygwin 1.1.7.

Using GCC 2.95.2-6 and Cygwin 1.1.7 there is no error message.
So what else can be ?

There is no reason why the gcc that you were using should be unable
to work with 1.1.7.

Again, if you are having problems, specific error messages are
an absolute requirement.

Yes, it is another kind of problem.
I have just 4 days with cygwin, so please forgive me.

I'm running postgresql, so I have to use cygwin 1.1.7 (thats what 
this list's archives says and works for now)

Yesterday I downloaded gcc, and it didn't worked, so I though it has
something to do with the lib/686 files, cause the errors were 
noticed there.

But the problem is the last gcc is linked against the last cygwin,
now I'm using an older gcc and it compiles things right.

Thanks for your patience.

Nicolay
