The process to use an existing configuration is not to copy files, but to tell crosstool-NG to use an existing sample: ?ct-ng i686-nptl-linux-gnu > Could you take a look, see if there is a fix? (Excerpt from your build.log:) [ERROR] ? ?i686-nptl-linux-gnu-gcc: Internal error: Segmentation fault (program as) [ALL ?] ? ?Please submit a full bug report. [ALL ?] ? ?See <http://gcc.gnu.org/bugs.html> for instructions. As you can see by yourself, it's not crosstool-NG that fails, but 'as' that is segfaulting. It is difficult to remotely solve a segfault. There can be various causes for a segfault. To try to debug this, ask yourself the following questions: 1) Does it happen again if you re-run the build? [Yes] ? - no: see (A), below ? - yes: go to question 2 2) Does it happen systematically at the same point? [Yes] ?- no: see (A) below ?- yes: go to question 3 3) Does it happen if you select other components for the toolchain? [Not sure] ? - no, see (B), below ? - yes, go to question 4 4) Does running other CPU/memory intensive applications (eg. video encoding ? or other big compilation...) also segfault? [No] ? - no: see (A), below ? - yes: see (B), below (A) There is a non-reproducible glitch somewhere, most probably due to [Not sure] ? ?any or many of: ? ?- CPU/memory over-heating ? ?- CPU/memory over-clocking ? ?- one or more bad memory module(s) ? ?This is known as the infamous "SIG11 problem", with explanations and ? ?solutions described there: http://www.bitwizard.nl/sig11/ (B) Indeed, there is a problem when building this very source code. ? ?In this case, try re-running the same compilation command manually ? ?with debug turned on ( eg.: -v --verbose -Wa,-a=as-debug.log ) and ? ?see what it says. Sorry I can't help you more. Next time, please post to the crossgcc mailing list, there are many nice and knowledgeable people hanging on there. Regards, Yann E.
