I have install boost library using this: $ sudo port install boost It seems download and compile fine on my local machine.

But then i tried to compile a simple echo client example from http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/examples.html

I get a bunch of compiler errors. I am using "g++ -o block_client blocking_udp_echo_client.cpp "

Here are some of the errors: $ g++ -o block_client blocking_udp_echo_client.cpp blocking_udp_echo_client.cpp:68:10: error: #include expects "FILENAME" or <FILENAME> blocking_udp_echo_client.cpp:69:10: error: #include expects "FILENAME" or <FILENAME> blocking_udp_echo_client.cpp:70:10: error: #include expects "FILENAME" or <FILENAME> blocking_udp_echo_client.cpp:71:10: error: #include expects "FILENAME" or <FILENAME> blocking_udp_echo_client.cpp:83: error: stray ‘\’ in program blocking_udp_echo_client.cpp:108: error: stray ‘\’ in program blocking_udp_echo_client.cpp:112: error: stray ‘\’ in program

Thank you for any help.

From my experience building software on MacOSX, I suspect that the problem is that you have not correctly defined an environment variable or something like that. If you write a line like "#include " and the compiler either cannot correctly resolve 'boost' or if the symbol resolves in such a way that an invalid file specification is created, then you might get the kind of error message that you are seeing. Another possibility -- if you have code left over from Windoze, look for backslashes in file specs. MacOSX is a Unix-like system that requires SLASHES, not BACKSLASHES. So lines line "#include will NOT work.
