Hi All,
I am trying to run a program which is used for reading data from seial port.
But it is giving error message. I don't know how to solve that error
message. Please give me ideas to solve this. I am using gtkmm-2.4 and os is
Linux - ubuntu.
Here I have attached my program and the error message:
#include <gtkmm.h>
#include "gtkmmconfig.h"
#include <fcntl.h>
#include <iostream>
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
class serialport
{
public:
int read_fd;
Glib::RefPtr<Glib::IOChannel> iochannel;
Glib::ustring buf;
bool MyCallback(Glib::IOCondition io_condition);
serialport()
{
read_fd = open("/dev/ttyS0", O_RDONLY);
// connect the signal handler
Glib::signal_io().connect(sigc::ptr_fun(MyCallback),
read_fd, Glib::IO_IN);
// Creates a iochannel from the file descriptor
iochannel = Glib::IOChannel::create_from_fd(read_fd);
}
};
bool serialport::MyCallback(Glib::IOCondition io_condition)
{
iochannel->read_line(buf);
std::cout << buf;
if (buf == "Q\n")
Gtk::Main::quit ();
return true;
}
int main(int argc, char *argv[])
{
serialport win;
return 0;
}
For compilation I am using this command :
g++ IO.cc -o IO `pkg-config gtkmm-2.4 --cflags --libs` `pkg-config --libs
gthread-2.0`
Error:
IO.cc: In constructor 'serialport::serialport()':
IO.cc:29: error: no matching function for call to 'ptr_fun(<unresolved
overloaded function type>)'

Thank you!
