Hi,
I downloaded the "chat_client.cpp" from the boost website (http://www.boost.org/doc/libs/1_37_0/doc/html/boost_asio/examples.html) and try to compile it on Cygwin (see my compile statement below..), but it failed. It's worked on Linux (without the -D__USE_W32_SOCKETS -D_WIN32_WINNT=0x0501) , however.
Thanks in advance for your help.
Compile statement:
g++ -o chat_client chat_client.cpp -D__USE_W32_SOCKETS -D_WIN32_WINNT=0x0501 -Wall -I/opt/boost/include -L/opt/boost/lib -lboost_thread -lboost_system -lboost_t
