--- Comment #2 from H.J. Lu <hjl.tools at gmail dot com> 2012-11-13 03:48:39 UTC --- After I fixed configure.ac, "make install" gave me: /bin/sh ../libtool --mode=install /usr/bin/install -c libasan.la '/export/build/gnu/gcc-x32/release/usr/gcc-4.8.0-x32/lib/../lib' libtool: install: error: cannot install `libasan.la' to a directory not ending in /usr/gcc-4.8.0-x32/lib It can't tell "/usr/gcc-4.8.0-x32/lib/../lib" is the same as /usr/gcc-4.8.0-x32/lib.
