Gah, thanks for the information. We need to update the website; I've been using libMesh successfully with gcc-4.8 for a while, and once with whatever gcc-4.9-pre version is available in the Ubuntu PPAs. > I highlight here some of the errors I get during the configuration stage: > > gcc version 4.7.3 (Ubuntu/Linaro 4.7.3-7ubuntu3) > configure:5662: $? = 0 > configure:5651: /usr/bin/gcc-4.7 -V >&5 > gcc-4.7: error: unrecognized command line option '-V' > gcc-4.7: fatal error: no input files > compilation terminated. > configure:5662: $? = 4 > configure:5651: /usr/bin/gcc-4.7 -qversion >&5 > gcc-4.7: error: unrecognized command line option '-qversion' > gcc-4.7: fatal error: no input files > compilation terminated. These aren't actually errors; configure is just autodetecting which compiler flags your compiler does and doesn't support. > configure:10667: /usr/bin/gcc-4.7 -E conftest.c > conftest.c:12:28: fatal error: ac_nonexistent.h: No such file or directory This is an *intentional* error; configure is making sure that your compiler gives a failure code on exit when the preprocessor fails. > In file included from /usr/include/c++/4.8/unordered_map:35:0, > from conftest.cpp:56: > /usr/include/c++/4.8/bits/c++0x_warning.h:32:2: error: #error This file > requires compiler and library support for the ISO C++ 2011 standard.

This *probably* isn't an error; we test for compiler/STL support for several different versions of hash table based containers, and on recent gcc versions this particular hash table should indeed only be enabled when using C++11. > The makecheck.log also includes some errors that prompted me to write this > email. Send us those? We still might have to back up into the configure logs to figure out what caused them, but at least in "make" there shouldn't be any expected errors to distract from whatever the real problem is. --- Roy ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
