Re: [Boost-users] Using boost::function and boost::bind

There seemed to be an error here: addCommand("clear", boost::bind(&Console::clear, this); If changed to addCommand("clear", boost::bind(&Console::clear, this, _1); everything works perfectly. Boost is amazing! A Arabadji wrote:

Hello people!

I am a new boost user, and I am trying to implement a console for a game, which binds console commands to functions. These functions can come from different objects and this is why I decided to try using boost.

I am using Visual Studio 8.0 SP1.

I have something like this:

//all functions are of generic structure //the return nothing and they take a vector of arguments typedef boost::function1< void, std::vectorstd::string& > funcHolder;

//I also have a hash table, which holds function references and the //relative commands:

std::map commands;

//Finally I have a function: void Console::addCommand(const String &command, funcHolder f) { std::map::iterator t = commands.find(command); if(t == commands.end()) commands.insert( make_pair(command, f) ); else commands[command] = f; }

All of these things are members of a Console class. So once I added these, I tried adding this line to the constructor:

addCommand("clear", boost::bind(&Console::clear, this);

//clear method void Console::clear( vectorstd::string& args ) { lines.clear(); }

During compilation I get C4180 warnings. I have heard that those are due to VS8.0 SP1 compiler bugs, so I ignore them but then I get a following error:

Project : error PRJ0002 : Error result 1 returned from 'C:\Program Files\Microsoft Visual Studio 8\VC\bin\cl.exe'.

Compiler basically crashes.

Any ideas what might be wrong?

I thank everyone in advance, Artyom
