error: ‘size_type’ is not a member of ‘boost::interprocess::message_queue’

The program is compiling and running in my friends system correctly but when I am trying to execute on my system it is showing the above error at the following line.

message_queue::size_type recvd_size;

I am also included the namespace

using namespace boost::interprocess;

I have installed the latest boost library, using sudo apt-get install libboost-all-dev but again the compiler is showing error message as error: ‘size_type’ is not a member of ‘boost::interprocess::message_queue’

Probably you need to specify where boost's headers are.

-I /<path_boost>/include

If it are in:

/usr/local/include

You need this link. This because in default PATH of linux isn't specified.

If you open a console and digit:

echo $PATH

you'll see what path is "visible".

If you want to modify it:

sudo nano /etc/environment

And add to PATH the string:

:/usr/local/include

UPDATE
Final step, logout+login or refresh /etc/environment, look here.

If you change it to std::size_t it will work but I think the efficient way is to follow the @Velthune's answer.

Your compiler is telling you exactly what is wrong. boost::interprocess::message_queue as described here has no size_type element. There are some functions there that return size_type so you might be interested in doing something like this:

int maxMessages = myMessageQueue.get_max_msg();
