Thread: [Cppcms-users] chat.cpp examples and boost/bind.hpp problem

Hello!

Newbie here; loving the framework so far!

Running on ubuntu 16.04. Downloaded cppcms-1.2.1.tar.bz2 and followed instructions to build and install. No errors.

Simpler examples like, hello_world, url_mapping and others build and run correctly.

However, ~/cppcms-1.2.1/examples/json_rpc_chat/  fails to build:

markhurst@ubuntu:~/cppcms-1.2.1/examples/json_rpc_chat$  make
g++ -O2 -Wall  -g chat.cpp -o chat -lcppcms -lbooster
chat.cpp:23:26: fatal error: boost/bind.hpp: No such file or directory
compilation terminated.
Makefile:7: recipe for target 'chat' failed
make: *** [chat] Error 1

I've searched best I can in online documentation, mailing list, and can't find solution. Because instructions say boost is NOT needed, and should not be used anyway:

  1.  Why does <boost/bind.hpp> and actual use of boost::bind() appear in chat.cpp and other example sources?
  2.  How do I fix the problem? Are there corrected examples?

THANK YOU, anyone who has an answer. I'm trying to demo the framework to our development team and show the more complex capabilities.

in geneally allmost all examples are implemented using C++2003 so boost was
used for simple things not in C++11 yet. You can either use boost header
only or use std::bind or C++11 lambda for this stuff

Not anything critical.

BTW if you look to the first lines in the code

#ifdef USE_STD_TR1_BIND
  #include <tr1/functional>
  using std::tr1::bind;
#elif defined USE_STD_BIND
  #include <functional>
  using std::bind;
#else
  #include <boost/bind.hpp>
  using boost::bind;
#endif

So just define USE_STD_BIND and you are good to go
