Re: boost::filesystem help needed

I am also trying unsuccessfully to use the boost filesystem library.
I am getting an undefined symbol error when attempting to link the
example simple_ls.c program.  I am also puzzled by the lack of .so
libraries, but I can use only .a's if necessary.

Could someone post a command line that will compile and link
simple_ls.c on any linux with any gcc ?  I think I could work my way
forward from that, if I had it.

I copied the
libs/filesystem/build/bin/libboost_filesystem.a/gcc/debug/runtime-link-dynamic/libboost_filesystem.a
file to /usr/lib.  I also have the boost header files copied to
/usr/include/boost.

I have been trying variations on this command line and been getting
pretty much the same error:
