Looks like the (fairly old) gcc/g++ in /usr/local is misconfigured; it definitely tries to link a 64-bit (x86_64) C++ program against the 32- bit libstdc++.so (in /usr/local/lib) instead of the 64-bit version in / usr/local/lib64. (Actually it is forced to do so by libtool.) -Leif -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
