Hello,
I am in the middle of the complicated process of trying to restore gcc3 to
my cygwin install, while still keeping gcc 4.7. Up to a few months ago, gcc3
and gcc4 were installed alongside each other in cygwin. The gcc link pointed
to gcc4 and if I wanted gcc3, I used gcc-3 when indicating the compiler in
make. This worked well, but when cygwin upgraded to 4.7, the package manager
removed all gcc3 files and binaries from my install, instead of just
upgrading gcc4 and leaving version 3 as it was. I still have not received an
explanation as to why it was necessary to remove version 3, as opposed to
leaving it the way it was with both compilers available.
At any rate, I am looking into building gcc3 from src so I will still have
it available. In the past, I was using gcc 3.4. I have found the src for
3.4.4-3.4.6 at ftp://gd.tuwien.ac.at/. I am looking for some notes for how
to build this for cygwin.
I did at one point manage to get 3.4.4 installed on my current cygwin by
using the cygwin time machine, but when I tried to compile with it I got an
error.
#error ERROR: You must use a GNU Compiler version >= 3.4.5.
I think this was from a header file _mingw.h. For this reason, should I make
sure I build 3.4.5 or 3.4.6 and stay away from 3.4.4? I guess I'm asking if
3.4.5 or 3.4.6 would be more compatible with my 4.7 gcc installation.
Assistance would b greatly appreciated.
Unless you have a very good reason (and I can't see any) you should
use the latest release from the 3.4 branch, i.e. 3.4.7
Thanks,
The ftp site I downloaded from only went up to 3.4.6. I guess I will
have to fish around some for the last version. Any suggestions on where
to look?
I could also use a link for tips on compiling gcc under cygwin if anyone
knows where some documentation is.
