Re: Problem while configuring gcc3.2

[Pardis Beikzadeh]

Hi,

I'm having a problem while installing gcc3.2. I'm trying to install
gcc3.2 for my installation of cygwin because anything higher than that
won't work if I try to compile mex files for Matlab. Unfortunately
when I try to configure gcc3.2 (before getting to the bootstrap step),
I get an error because no proper cc is found. This is of course
because I uninstalled my gcc3.4 in order to install gcc3.2 from
scratch according to the suggestion in the email below from the gcc
mailing list. Could you please tell me how to solve this problem?
Where can I get an installation of cc that will work with gcc3.2? It
seems like I'm stuck with a chicken and egg problem because it seems
like I need gcc before I can install gcc.

Also 'make bootstrap' doesn't work without running configure, so I'm
not sure what the "recommended way" mentioned in the email below
means.

Thanks in advance,


Pardis Beikzadeh

The bootstrap in Jim's reply means, I think, building a minimal (only C 
front-end) gcc-3.2 first using gcc-3.4. Then you can use the minimal 
gcc-3.2 to build a full gcc-3.2.

Maybe installing a gcc-3.3 based Cygwin-release like the '1.6.6' and 
then building gcc-3.2 with it would succeed immediately :

http://www.filewatcher.com/m/cygwin-1.6.6.zip.496537660.0.0.html

Or simply finding a gcc-3.2-based Cygwin-release from the net....

It can also be possible that gcc-3.2 expects some old Cygwin-runtime as 
the binutils & C-library components, trying to get gcc-3.2 to work
with uptodate binutils and Cygwin-runtime may simply be impossible or 
very hard :(

Thanks for the advice. After reading your suggestion I tried to find
an older installation of Cygwin. I found one but I have yet to try it
and see if in fact gcc3.2 does solve my other problems.

I don't see any suggestion in the mail you quoted that says to uninstall gcc3.4

I suggest you don't uninstall gcc3.4 and instead configure gcc3.2 so
it installs to a different path. That way you will have two versions
installed in separate locations.

It means following the usual installation instructions given on the
gcc website, which say to run configure first. Once you've configured
you can run 'make bootstrap'
