RE: using gcc 3.3.3
Thanks. I seemingly compiled gcc 3.4 20040310 successfully, once I had installed bison and flex into cygwin. I'm going to try the decisive test tonight which will be to rename all the g++ files other than the one in gcc_34 directory, compile a C++ program, then rename the cygwin1.dll to cygwin2.dll, then try to run the program. If it runs, I've got gcc 3.4 working correctly. This way, I know that the gcc 3.4 is definitely the only one being used, and that it's not relying on cygwin for the program to run (although it is to run the compiler). Now... is it possible to use -mno-cygwin on the compiler *itself*..., maybe? DISCLAIMER.

RE: Using gcc 3.3.3
Oh right! OK, sorry - I didn't know there was a mailing list. I was under the impression that you just sent an email to cygwin and somebody at cygwin who knew the works picked it up, and it went on the mailing list so it came up in searches as a by-product of that. I thought that all message posters got sent all the replies via email, rather than having a website that you have to explicitly check. I've seemingly successfully built gcc 3.3.3 with 3.3.2, which was built from 3.3.1. Doing 'make bootstrap' worked apart from when I tried to compile 3.3.3 with 3.3.1, which didn't work, which is interesting in that each one can only 'give birth' to the next one, rather than skip one. Also, just in case it isn't clear, we will eventually be releasing gcc 3.3.3 (and even 3.4), too, so this exercise is pretty much academic. Well, that is precisely why I am pursuing it, for academic interest. It's not like I actually think that gcc 3.4 will produce so much better code than 3.3.1 for my game that I *need* to have it, but it's the challenge of building it and letting it bootstrap itself that's the fun part of it, at least at the moment anyway. So, while it might not be the typical developer's prime convern, given that I do have this motive, is there any particular configurational route you can suggest to me to enable me to jump up the ladder and be able to build one of the 3.4 snapshots? for instance snapshot 3.3-[mmmdd] might be easily built from 3.3.3, which is then used to build 3.4[mmdd] ??? I'm just eaten up by the fact that 'there's something newer out there... they haven't been sitting on their arses, so they must have been putting some more good into the thing!'

Since gcc 3.3.3 isn't part of the Cygwin distribution yet, you would need to patch your local version if you want this functionality prior to it's inclusion in Cygwin. Actually, -mno-cygwin has been part of standard gcc for some time. The cygwin version of gcc does have some additional patches which make things more robust but for gcc 3.4, these changes are all part of the base. So, the bottom line is that -mno-cygwin should more or less work in most versions of gcc. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
RE: Using gcc 3.3.3
'man patch'. But according to Chris, who knows more about Cygwin's gcc than I do, -mno-cygwin should be configurable with vanilla gcc sources. So, if you're having difficulty with your locally built gcc/g++, you'll need to figure out what's different in your environment.

The -mno-cygwin option works but you still have to install mingw components for complete functionality just like in the cygwin distribution. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
RE: Using gcc 3.3.3
Thanks I tried building 3.3.3 using 3.3.1, which didn't work when doing 'make bootstrap'. But then I did a successful 'make bootstrap' of 3.3.2 using 3.3.1. The bootstrapped 3.3.2 works fine, and claims to have been compiled by itself not 3.3.1. Even -mno-cygwin works fine on it. So I'm now happy, in that I've used my 'on-a-plate' compiler to compile myself a better one. But I'm greedy and curious, I want more. So now I've included in the path environment variable the path to this before the cygwin path, and I'm now trying to make bootstrap 3.3.3 using 3.3.2. Do you think it should work? When I type 'man patch' it says 'no manual entry for patch', do I have to install this extra? And what of this Chris geezer, does he have a known email address? Can he be contacted to be asked questions such as this? -Original Message- From: Larry Hall [mailto:[EMAIL PROTECTED] Sent: 15 March 2004 02:11 To: Ben Taylor; Cygwin List Subject: RE: Using gcc 3.3.3 'man patch'.
