Hi, I am trying to install gcc 4.6 on ubuntu 10.10 which has 4.4 installed. However the ./configure failed! the config.log is available and the first part of it which is odd for me is: $ ./configure ## --------- ## ## Platform. ## ## --------- ## hostname = magma uname -m = i686 uname -r = 2.6.35-22-generic uname -s = Linux uname -v = #33-Ubuntu SMP Sun Sep 19 20:34:50 UTC 2010 /usr/bin/uname -p = unknown /bin/uname -X = unknown /bin/arch = unknown /usr/bin/arch -k = unknown /usr/convex/getsysinfo = unknown /usr/bin/hostinfo = unknown /bin/machine = unknown /usr/bin/oslevel = unknown /bin/universe = unknown PATH: /usr/local/sbin PATH: /usr/local/bin PATH: /usr/sbin PATH: /usr/bin PATH: /sbin PATH: /bin PATH: /usr/games ## ----------- ## ## Core tests. ## ## ----------- ## configure:2222: checking build system type configure:2236: result: i686-pc-linux-gnu configure:2283: checking host system type configure:2296: result: i686-pc-linux-gnu configure:2316: checking target system type configure:2329: result: i686-pc-linux-gnu configure:2383: checking for a BSD-compatible install configure:2451: result: /usr/bin/install -c configure:2462: checking whether ln works configure:2484: result: yes configure:2488: checking whether ln -s works configure:2492: result: yes configure:2499: checking for a sed that does not truncate output configure:2563: result: /bin/sed configure:2572: checking for gawk configure:2602: result: no configure:2572: checking for mawk configure:2588: found /usr/bin/mawk configure:2599: result: mawk configure:3919: checking for gcc configure:3935: found /usr/bin/gcc configure:3946: result: gcc configure:4175: checking for C compiler version configure:4184: gcc --version >&5 gcc (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5 Copyright (C) 2010 Free Software Foundation, Inc.
