Can you explain, please, how did fflush(stdout) solve your problem ?

You only have to try to link if the target is an executable file. If the target is a library, then try to build the final executable too.

It is not, the code i posted is only a proof of concept.

You can do like this:


class ServiceImplClass
{
class SimpleThread
{
SimpleThread(ServiceImplClass* pParent); // keeps a reference to the parent; used to access...

- use netstat on the server host to see if the server is up;
- use telnet <IP> <port> from the real client machine (or a different computer in your network) to see if the server is reachable from...

The nonblocking mode is not important in this case. You must always loop until you receive all the bytes you wanted to, like this:



int n=0;
do
{
n += recv(socket, buffer, 1024, 0); // also...

This is the signature of the select function:


int select(int nfds, fd_set *readfds, fd_set *writefds,fd_set *exceptfds, struct timeval *timeout);


Based on this, you are using this function...

You have this:

istream & operator >> (istream & s, Candidate & v)
and you wanted to use this:

istream & operator >> (istream & s, Candidate* v)

From your code I understand that you wanted to instantiate Singleton<T> for T=SlaveManager. The 2 errors tells that, at the point of the instantiation, the linker is unable to find the definitions...

Did you solve your problem? If not, this may help

- try this command: "nm libbase.a | grep Malloc2D_uchr" to see if the library does contain your function
- in file bmalloc.h wrap your...

Are you sure the server is running? You can use telnet to test if the server is listening.

You can try this:



template<typename T>
T addone(T x)
{
return x+1;
}

I have no experience with mobile devices, but for a PC:
1) sendto() is to be used with UDP sockets, not TCP.
2) if you have a TCP socket which is not connected anymore, you can reconnect it to...

Your operator is incorrect because it is recursive (it calls itself) and doesn't have a stop condition. If you run thatcode, you'll get and endless loop.

There are not "static blocks" in C++; if you want to have static initializers per class in C++, you must take care to call them explicitly before making any object of that class. Also, in C++, global...

I think that you should check always if there are changes to your file. If your window is not active, it doesn't receive messages and your test doesn't take place. You may try this

I need to be able to create such BigDecimal instances out of double literals (like Java does).
But i think you are right, maybe the response to my question is the "precision", if the number of...

Java doesn't seem to have the same issue; that is why i think there is a way to "guess" the "exact" value in this case.

Hello,

I have the following problem in C++. I wrote a C++ implementation of the java class BigDecimal, but i have a problem with the double literals. So, i have this code fragment:

...

Try this comamnd: file <your_file_name>

It is returning a non-const object because this is its purpose, to remove the const.
In C++ you cannot call a non-const method for a const object. If you have a non-const method that doesn't affect...

Once you declare a const variable, the compiler is free to place it into an "read only" code segment; if this happens, it is not possible to change this variable anymore. If you still want to access...

You can define an "operator new" in your Base class; the compiler calls this operator with the right size of the memory to be allocated. But you must find a solution for stack allocated objects...

Try this:



namespace __gnu_cxx
{
template<>
struct hash<MyClass*>
{
bool operator()(const MyClass* s1) const

The initialization order for static variables defined in different translation units is undefined in C++ - this could be a reason; check the dependences between your static members/global variables.
