1) You describe to much path information in the #include directive in 
simple_ls.cpp . Like the Boost's .hpp, just start with "boost/(...).hpp".

I fixed the path information in the #include directive to be "boost/filesystem/...

2) Then make sure your compiler command line at least mention
"-I /user/local/include" or "-I $(INC)" where INC 
~includes~ "/user/local/include".

I get further, here is the new AIX compiler error:

xlc++ -o simple_ls simple_ls.cpp -I /usr/local/include

2a) On AIX, look inside your makefile.

What am I looking for?

2b) On MSDEV6, add "c:\boost\include\boost-1_32" in your project settings. More specifically in the "C++" tab, under "Preprocessor" category (drop-down list), and at "Additional include directories:".

I did this and I can now build, but I get a linker error:

LINK : fatal error LNK1104: cannot open file "libboost_filesystem-vc6-sgd-1_32.lib"

Thanks.
