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>

If I'm reading this correctly, the error is on line 68 of blocking_udp_echo_client.cpp, but when I follow your link, then the link to that file, copy the example and paste it into vi, I see that the file is only 60 lines long.

I would guess that the file you're compiling doesn't contain what you think it does, or you added stuff to the end of the file that isn't legal C.

Perhaps you're trying to compile html? In Christ, Steven Watanabe

Sorry. I copy-and-paste the wrong compile error: $ g++ -o echo_client blocking_udp_echo_client.cpp blocking_udp_echo_client.cpp:14:26: error: boost/asio.hpp: No such file or directory blocking_udp_echo_client.cpp:16: error: ‘boost’ has not been declared blocking_udp_echo_client.cpp:16: error: expected nested-name-specifier before ‘udp’ blocking_udp_echo_client.cpp:16: error: ‘udp’ has not been declared blocking_udp_echo_client.cpp: In function ‘int main(int, char**)’: blocking_udp_echo_client.cpp:30: error: ‘boost’ has not been declared blocking_udp_echo_client.cpp:30: error: ‘io_service’ was not declared in this scope blocking_udp_echo_client.cpp:30: error: expected `;' before ‘io_service’ blocking_udp_echo_client.cpp:32: error: ‘udp’ has not been declared It seems the compiler can't find the boost library on MacOS X. But I have installed it via: $ sudo port install boost It seems download and compile fine on my local machine. On Fri, Jul 24, 2009 at 8:30 AM, Steven Watanabe wrote:

It sounds like you don't have the include path for boost as part of your build environment.  By default I believe it should be installed somewhere like '/opt/local/include/boost'.  If you are using a compiled boost library, you may also need '/opt/local/lib'.  Can you post more information on what build system you are using? (Xcode, eclipse, make, etc).

I am building it from command line: $ g++ -o block_client blocking_udp_echo_client.cpp Can you please tell me how to add include path and boost library in g++ command? Thank you.

Thanks. I have created a XCode project and I have add Header Search Path to /opt/local/include/boost Library Search Path to /opt/local/lib. But I still have this error: "boost::system::get_generic_category()", referenced from: __static_initialization_and_destruction_0(int, int)in main.o __static_initialization_and_destruction_0(int, int)in main.o __static_initialization_and_destruction_0(int, int)in main.o I found this thread http://www.nabble.com/installing-boost-on-Mac-OS-X-(version-10.5.5)-td200872... but it did not solve my problem.

This is because you did not link to Boost.System library.

I have add /opt/local/lib to my LIBRARY SEARCH PATH in my xcode project info. And in my /opt/local/lib, I find this (I assume that is Boost.System library): -rw-r--r-- 2 root admin 80600 Jul 23 16:31 libboost_system-mt.a -rwxr-xr-x 2 root admin 30988 Jul 23 16:30 libboost_system-mt.dylib*
