version 'next door'.  That lets you transfer files, inspect, alter, fix things 
of the sibling. Or clean it out and start with another.

. . which may be just another copy of the release version equipped with the Gcc 
4.x  compiler suite.

PREVIEW or HEAD are probably not needed for your project at all *unless* their 
newest features - not just Gcc 4.x - are specifically part of the project itself.


Bill Hacker

and "Trevor Kendall" advised this:

If you are using 1.8.x:
In /etc/make.conf uncomment WANT_GCC41=yes and rebuild.
If you are using HEAD, it is built automatically already.

To use it set CCVER to gcc41.
but "Matt" said "please do NOT use HEAD". so i used "LATEST preview
release" which was GCC 3.4 based. In "/etc/mk.conf" i added a line
"WANT_GCC41=yes" but i do not know how to rebuild ? i  tried Google
and got this:
# make buildworld
# make buildkernel
More on this at the end.

when i try this i get this message: "do not know how to build world".
funny message, i thought.  so i have these questions:
1.) Is it a good idea to use  DragonFly preview release as my
general-purpose OS. actually, i want learn UNIX and i want GCC 4.x to
work on a C++ project. i just use a Window Manager, xine-ui, firefox,
emacs, bash, gimp, audacious or xmms and nothing else. i don't use
Well, most of those applications will probably be available from pkgsrc 
and if not then some other workalike will be. And it's quite a good 
system to learn about UNIX on since it does not try to hide it's 
heritage like some Linux distros (Ubunto).

2.) how to rebuild the preview release for gcc4.x and how long this
process will be ?
It depends a bit on your computer and internet connection, but it can 
take a up to a couple of hours on a not to old PC.

3.) is it necessary to do this before rebuilding world:

cvs -d anoncvs at co pkgsrc

even after 4 hours, it is still downloading packages :-(. is it
downloading the source code of every package ?
No, it's not necessary, in fact I would not do that at all if I were 
you. Using binary packages are much easier, see below for more info.

4.) DragonFlyBSd guide also advises to use "cvs up" after step 3. what
is it and how much time will that take ?
It downloads the DragonFly sourcecode to your computer so that you can 
compile it. If you have a slow connection you might want to download a 
compressed tarball of the sources instead of using cvsup. You can 
download tarballs from here:

hmm.. this page gives lots of information tha i snot present in
"DragonFlyBSD handbook":
Yes, the steps under Keeping up to date are good, but use the file




it you want preview. If you have a slow connection you might want to 
download a tarball as mentioned above.

For third party application don't follow what's written under Installing 
software, look at and 
follow the steps under the section Pre-built pkgsrc packages, but use 
the addresses found on 

if a package you want can't be found there take a look in
