Connect cygwin with old version of gcc

Connect cygwin with old version of gcc

[yu xuesheng]

Hi. I just wonder how to connect the old version of GCC to Cygwin? I have a large code, which only can run under GCC 3.3.3. Thank you for your help!

Looks like it's still an available Cygwin package but it's old enough that
'setup.exe' won't present it to you by default.  You'd need to download
all the needed packages at that via 'wget' or something similar to your
local disk with the same directory structure as your usual download
directory.  You could then point 'setup.exe' at that local directory and
install from it.  If you already have these packages in your existing
local download directory, you may be able to get 'setup.exe' to look
at those directly by removing the newer versions and removing/hiding
the top-level 'setup.ini'.  This is advanced manipulation of 'setup.exe'.
If you understand this well enough to try it, you may find it simpler
to install the packages manually (tar + running postinstall scripts).
But that's advanced stuff too and should only be done "if you know what
you're doing"(tm).  If not or if you're not willing or able to solve any
problems that might arise from taking these approaches, you shouldn't
bother.  All of this puts you into the realm of things not supported by
this list.  So if you complain to this list later about problems you see
in the process or with the result, it may very well fall on deaf ears.

Good luck.

If you believe that this package is the sum total of what you need to
do what you want, then you want to:

>> ...download

When I say your "usual download directory", I mean your local Cygwin
download directory.  That's the directory you tell 'setup.exe' to use
for the packages it downloads.  You may be able to get away with putting
the package in a directory by itself and pointing 'setup.exe' at that
(i.e. specifying this as the local download directory and telling
'setup.exe' to install from the local directory).  I've never tried this
but I believe that such functionality was at least once supported in
'setup.exe'.  If that doesn't work, then:

I'll take this opportunity to repeat myself a little more:

But you sound like the adventurous type so go ahead and have fun! ;-)

Thank you Larry!
You said
"You could then point 'setup.exe' at that local directory and
install from it. "

I already downloaded gcc-core-3.3.3-3-src.tar.bz2, how can I make setup.exe do the installation from this file?
