Hi, I just finished debugging it in visual studio 2012, it says:
========== Build: 176 succeeded, 1 failed, 0 up-to-date, 25 skipped ==========

I couldn't find the failed one except this if it is (not sure how to find it):
28>------ Build started: Project: libaprutil, Configuration: Debug x64 ------
4>  t_bitst.c
28>  The system cannot find the file specified.
28>  The system cannot find the file specified.
