On AIX v5.2 here are the boost_filesystem* libraries I have under /usr/local/lib
 
libboost_filesystem-xlc-1_32.a
libboost_filesystem-xlc-1_32.so
libboost_filesystem-xlc-d-1_32.a
libboost_filesystem-xlc-d-1_32.so
libboost_filesystem-xlc-d.a
libboost_filesystem-xlc-d.so
libboost_filesystem-xlc-mt-1_32.a
libboost_filesystem-xlc-mt-1_32.so
libboost_filesystem-xlc-mt-d-1_32.a
libboost_filesystem-xlc-mt-d-1_32.so
libboost_filesystem-xlc-mt-d.a
libboost_filesystem-xlc-mt-d.so
libboost_filesystem-xlc-mt.a
libboost_filesystem-xlc-mt.so
libboost_filesystem-xlc.a
libboost_filesystem-xlc.so

On AIX (maybe all unix's) boost libraries are found in /usr/local/lib

No boost libraries with a .lib extension

the actual xlc++ compiler command line that worked was:
xlc++ -o simple_ls simple_ls.cpp -I /usr/local/include -lboost_filesystem-xlc-1_32 -L/usr/local/lib
NOTE: after the -l the three letters "lib" are removed from the front of the actual library name.

On my Windows 2000 the file "libboost_filesystem-vc6-sgd-1_32.lib" is found in c:\boost\lib
 
Martin, thanks for your help.  I would have never got this working without your assistane.
