I verified the the Ubuntu package was uninstalled. I ran "find /usr/lib
-name libcxx\*" to make sure there were no left over libs installed. I
installed the cxxtools libs to /usr/local/lib from my build. I ensured the
ldconfig was ran (as root) so the libs would be found properly. Currently,
that version is GIT version 7f195300e07dfd82dc81a8835ea02e27435769bc which
was the version where this howto was checked in. I tried the latest and
greatest before that. I have attached the source file I am compiling and
the output from running the command you specified.
To throw another wrench in the works, I tested compiling it with the
clang++ compiler. I do this from time to time because of the better
readable logging it provides compared to gcc. It compiles without issue
under clang. The issue seems to be between GCC and CXXTOOLS somehow.
Sadly, I can'y use clang with the project I hope to use cxxtools with.
Sending files in too emails because I tripped up the message size limit on
the list.
