i think that the problems you guys have been having are attributable to attempts to try to use a Guide that was written to support GCC 3.4.3 with the expectation that it will work interchangeably with GCC 3.4.4 (or any toolkit component upgrade). experienced Gentoo users know better.

just remember, i haven't actually tried it, and the GCC 3.4.4 version of the Guide isn't guaranteed to work yet, as GCC 3.4.4 is currently b0rken. :?

With the advent of GCC 3.4.4, alot of people are getting confused about where to post:


For GCC 3.4.4

:arrow: If you want GCC 3.4.4, then YOU ARE IN THE WRONG PLACE. :oops: instead, you should use this version of the Stage 1/3 Guide for 2005.0 and GCC 3.4.4:
http://forums.gentoo.org/viewtopic-t-345229.html



:arrow: If you run into problems and need support, then post to the GCC 3.4.4 Support Thread:
http://forums.gentoo.org/viewtopic-p-2472891.html#2472891



If you are using GCC 3.4.4, PLEASE DO NOT POST TO THIS THREAD!



For GCC 3.4.3

:arrow: If you want GCC 3.43, then you are in the right place. :wink: use this version of the Stage 1/3 Guide for 2005.0 and GCC 3.4.3.
http://forums.gentoo.org/viewtopic-t-319349.html



:arrow: If you are using GCC 3.4.3 and you need support, then post to the GCC 3.4.3 Support Thread:
http://forums.gentoo.org/viewtopic-p-2240059.html


If you are using GCC 3.4.3, then POST SUPPORT REQUESTS TO THE SUPPORT THREAD!

thanks. :)

:arrow: Problems Setting Hostname & Domainname

the new stable branch versions of baselayout have deprecated the use of /etc/hostname and /etc/dnsdomainname in favor of /etc/conf.d/hostname and /etc/conf.d/domainname. if you install/update to sys-apps/baselayout-1.11.12-r4 or later and you've used the deprecated /etc/hostname and /etc/dnsdomainname methods, you'll notice boot warnings. you can make them go away by following the second set of examples in Section 10.2 of the Stage 1/3 Guide.

I was reading through this post and unless I missed it, I did not see this very well written document reffering to or applying to athlon-xp CPU's. Should I follow this documentation and change my Architecture, e.g. i686 or athlon-xp or not use this documentation for AMD CPU's at all?

I really hope this question makes sense.

The documentation is written using a Pentium as an example, with the idea that the reader would have the intelligence to change -march=pentium to say -march=athlon-xp to fit their particular x86 architecture. If thats too much for you to handle though, you could always check out the Jackass! project (the link is in my sig). We've got an Athlon-XP stage that's ready built so it will save you time and frustration.

The Jackass! Has Landed. :wink:

Here are a few pointers that will make your life on the Gentoo Forums easier both for you and for everyone else:


1. Documentation, Tips & Tricks is not a Support Forum, and this is an Instructional Thread, not a Support Thread.

The Support Thread is located HERE. Its hard to imagine that you could have missed the multiple boldfaced RED warnings about that, but if you did, please comply with the Forum rules and post all of your support requests to the Official Support Thread. That's why we have it. :wink:

Click Here.


2. What to do about changing to other CPUs is very plainly stated in the Guide. It seems that you didn't read this part:

Stage 1/3 Installation Guide wrote:
6.5 Configuring the USE Flags, Portage Options, and Compile Options: /etc/make.conf

In this example, we're compiling for the x86 architecture and a Pentium-class i586 subarchitecture. Our CHOST setting will be i586-pc-linux-gnu. Do not blindly follow the Guide and use this setting unless you are building for a 586-class computer! Use the appropriate tarball, CHOST setting, and architecture specifications for your processor.


3. Athlon-XP has been specifically addressed either in the Guide or the Support Thread.

I'd recommend using the text-search feature of your browser to find the information that already exists in these threads rather than asking someone to re-post it. Re-posting only adds alot of unnecessary bulk to the threads and in the big sheme of things, its counterproductive.


4. Please don't use ALL-BLUE posts.

In the context of the Stage 1/3 Guides and their associated Support Threads, we've been using the convention of "blue" posts to highlight important updates and support information that are essential for people who are troubleshooting problems. The purpose of the emboldened blue support information is to make these important announcements stand out from all of the noise in the support threads. Although this is not an official Gentoo Forums policy, its the convention that we've been following in the Stage 1/3 and Jackass! Support threads, so we'd appreciate it if you could follow the convention. By using bright blue text to solicit a support request in a Documentation thread, it appears that you've inadvertently broken some rules and conventions just to capture our attention. Now that your post has gotten our attention, if you could please remove the blue flags, that would help everyone.


5. The Jackass! Has Landed. Sith makes a good point. You should really check out The Jackass! Project (after editing the blue out of that previous post!).

thanks.

It seems like your guide calls for compiling glibc an unnecessary third time when you emerge -e system. How can we avoid this?

Use a Jackass! stage :wink: (link in my sig).

unnecessary? i would not call the final emerge -e system unnecessary. its absolutely essential to perform those passes to completely debug the installation. sure, there are other ways that this could be done, but they are MUCH more labor intensive and would require ALOT more seat time than simply performing an emerge -e system and taking an extended break from sitting at the console. the way that's mentioned in the Guide is the EASY way to do it. sure, there are other ways, but they're all HARDER.

the Guide states very plainly in the warnings provided that it is an advanced/expert installation method that will take a long time to complete. if you are not willing to spend the time on the Guide that is necessary to perform it in its entirety, then I recommend that you don't perform an install using this Guide. similarly, if you do not understand why the steps in the Guide are being performed, and you don't agree with them, I would recommend that you don't perform an install using this Guide.

if you don't want to follow the Guide, you don't have to. if you think that the third emerge of glbic is unnecessary, then don't do it. if you know enough to find another way to solve the problem, compile only the individual packages that need to be recompiled to solve the problem with retention in static libraries. just don't ask us for help when you make a mistake that borks your system. the recommended method works. other methods may not. feel free to experiment if you like, but if you deviate from the Guide and your solution doesn't work, don't ask us for help.

Well I installed it and it works perfectly, though there isn't much benefit to this install as compared to the normal particularly in the area of speed. I wasn't attacking you with the previous post.

there is a HUGE, MEASURABLE and undisputable difference in speed between a standard Gentoo install using GCC 3.3.5 and any install that uses GCC 3.4.3 and enables NPTL library. When you add GCC 3.4.3, NPTL, and the CFLAG optimizations that are used in the Stage 1/3 Guide, you HAVE to notice a significant speed improvement. if you're not experiencing an improvement, I'd say that there are only three possibilities that would explain your observations:

1. some component of your installation failed, and you're not actually getting the speed increase (ie: NPTL failure, b0rked GCC 3.4.3 libraries, etc.)

2. you are using subjective measurements such as perceived speed insted of objective benchmarks that provide firm and irrefutable numbers

3. you're just trying to yank my chain. :wink:

Just a note: I think the -finvisibility-inlines-hidden g++ option has been removed and/or implemented differently.

I am no compiler expert, but I think the option -fno-implement-inlines will accomplish the same thing?

Perhaps this should be updated in the guide, since this topic has a pretty high rank in a google search on gentoo+nptl

Is it okay to do this install through a knoppix livecd, or does it have to be done using a gentoo minimal livecd?

i've never done it using knoppix. i've only done it using the most current Gentoo Live CD. i have heard that other guys have done it using Knoppix, but never having done that approach, i couldn't begin to offer guidance or support.

have fun!

I did the install through knoppix =)

I did get the sandbox access error during the whole install, but once I rebooted, everything was fine.

I think its time to retire this version of the Guide in favor of the 2005.0 and GCC 3.4.4 version:

Is 2005.1 really the same install?

Edit: What I mean is Bob do you need to do anything different between the 2005.0 and 2005.1 install?

Edit: I will post this in the 2005.0 3.4.4 thread.

Nice article really lives up to its title "Faster than a Speeding Bullet... More Powerful than a Locomotive! ".
But libstdc++ has been upgraded to 6, so people will have to symlink libstdc++.so.6 to /usr/lib/libstdc++.so.5
