I just answered this in the other mail, to quote: Yes, this is because the Config is restarted again on each config change. This is an implementatino bug and probably the authors did not know better at that time (read 5 years ago). Though on that time the Config was not that slow because there where 2000 less packages and a handful of options less as well. The slowness is why we already started accelerating the worst code-pathes with Lua code. We already have on our Roadmap to rewrite the remaining parts, including a more inteligent implementation not restarting the whole Config process again after every Config change: http://www.t2-project.org/releases/ http://www.t2-project.org/developer/soc.html 2. i didnt like the package collection of the embedded target (perl, automake, etc, are not needed on my target system) so i've copied the embedded directory to another name, changed the title, and removed all packages i didnt want. this didnt work, and the Build-Target complained about all kinda errors (if needed ill do it again and post the exact errors). What is the easiest/quickest way to create a simple embedded system with only uclibc and busybox? and what is the way to configure what options i want on my busybox (on buildroot i could simple alter the config file under 'package' directory, but i dont see this on t2). Copying like this is usually fine. Maybe you just missed a little detail. Just do it again and post the detailed error, so we can help. For an introductoin about targets in T2 you can read the handbook at: http://www.t2-project.org/handbook/html/t2.target.html 3. related to my 2nd issue - what is the best way to alter the configuration files and configure options of the packages which are being built? i didnt see any information about this on the t2 tutorial. The target section of the handbook lists this: http://www.t2-project.org/handbook/html/t2.target.modifications.html 4. me too got an error on the gmp package (im using the t2-svn versions) - although ive read on the ML that this was fixed - am i missing something? Using the 6.0 branch should have worked. Maybe you used the trunk or the fresh 7.0 branch. Unfortuantly we had a regression in the C++ cross compiler STL header patch. This was fixed about a week ago. Can you retry and post if you still get this error? many thanks for this great product. i hope to be able to produce a useful distribution out of it once it works :) Thanks you are welcome!

[t2] Some questions about T2
I downloaded T2 v6.0.2, and I have some questions. I see that the package definitions are in the package directory, and was wondering if there is a way to update package definitions without downloading the entire toolkit? There are a number of architectures listed as supported. I am wondering how you do this. Since not all combinations of binutils-gcc-glibc work for every architecture, how do you define a working configuration for each arch? Does T2 provide any tools for capturing run-time configuration? For example, when I boot my machine into T2, and I change /etc/resolv.conf (or any of the files in /etc) is there some way to capture that? Can that information be folded back into package definitions? I see you've also made a comparison to Gentoo, and I am familiar with Gentoo. When you say that T2 does automated package build compared to the Gentoo ebuilds, what does that mean? Can I just specify a name somewhere and T2 will figure out how to download and build that package just based on the name? And how does T2 configuration compare to portage USE flags? Suppose I want to turn on IPV6 for my system, with Gentoo I would simply add 'ipv6' to my USE flags and rebuild the system. Does T2 provide this sort of high-level configurability that cascades down to the package level? Likewise, I tried building a basic embedded system, but it seems to want to build perl and X, and I want neither. Again, Gentoo USE flags would make it easy to turn this off, but I don't see how to do that with T2. What are the sophisticated wrappers in T2 that are better than the hardcoded CFLAGS in Gentoo? In Gentoo the make.conf file allows you to set system-wide CFLGAS which can be over-ridden on the command line for any package. And package ebuilds also allow you to set specific flags for a given package to override system or user choices (if they're known to be bad, for example). As far as libc choices go, Gentoo profiles define various libc alternatives, which claim to support system builds, although I have not used portage to build a uclibc system. On one final note, in trying to build with T2 for a basic embedded system, the build fails on building base/gmp with the following error, perhaps there is some way to recover from this (sorry, the config system is new to me): Due to previous errors, no 1-gmp.log file! (Try enabling xtrace in the config to track an error inside the build system.) --- BUILD ERROR --- Creating file list and doing final adaptions ... Processing static lib corrections ...
