I have compiled FreeImage 3.10.0 from source at /lib/FreeImage on Mac OS X 10.6. I can see that after compilation these files were copied: /usr/local/lib/libfreeimage-3.10.0.dylib /usr/local/lib/libfreeimage.a /usr/local/include/FreeImage.h CMake cannot find FreeImage, but I cannot even do #include <FreeImage.h> // not found I am...
Hi, I find my self repeating a single line of code in child constructors, which are passed two variables. The first of these variables is always used to initiate a protected variable (defined in the parent class). I was wondering if there is a way for me to do that assignment in the parent constructor - which is then inherited, and do t...
I need to know which are the APIs/library used for multithreading by MSVC . If there are more than one , please let me know which is the most widely used. If my question sounds too naive , its because I've never done threading before , and from my past experience , I know there are people here who can get me started/point me at the righ...
I recently posted a question asking for what actions would constitute the Zen of C++. I received excellent answers, but I could not understand one recommendation: Make header files self-sufficient How do you ensure your header files are self-sufficient? Any other advice or best-practice related to the design and implementation of he...

My team wants to build a "plugin" for firefox/chrome/IE. How do I use javascript to detect if this plugin (not extension) is installed? I would like to have a piece of javascript that can detect if a certain plugin is installed. Returns true if installed, returns false otherwise. For example...how do I get a list of plugins, and then ...
I'm running 2 threads ( assume they are pthreads for the moment) . Thread_1() makes a user-defined API call which ultimately does some work in the kernel . Thread_2() is totally in user-space. My question is : Can Thread_2() start executing by pre-empting Thread_1() while the API call is in progress , the control is somewhere inside th...
When you implement IDropTarget you must implement this: virtual HRESULT STDMETHODCALLTYPE Drop( /* [unique][in] */ __RPC__in_opt IDataObject *pDataObj, /* [in] */ DWORD grfKeyState, /* [in] */ POINTL pt, /* [out][in] */ __RPC__inout DWORD *pdwEffect)=0; I want to know what kind of data...
I have a vector<list<customClass> > I have an iterator vector<list<customClass> >::const_iterator x When I try to access an member of customClass like so: x[0]->somefunc(), I get errors of a non-pointer type/not found. ...
Initially this may seem overly abstract or philosophical, but I am genuinely interested to see if someone has a convincing argument in favor of one implementation over the other. Given operator< for std::pair<T1, T2>, which would be the better implementation: return x.first < y.first || x.first == y.first && x.second < y.second;...
I would like to understand why I am getting a bus error with this code. int main() { int p=34; int *pp= (int *) ((char *)&p+1); cout<<*pp<<"\n"; return 0; } ...
I am integrating a medium-sized (10,000 or so lines) program written in C into a C++ program. I have created a new class, BWAGenome as an interface to the C code, so any access to the C functions is encapsulated. I am compiling everything with the g++ compiler. The .o files are all generated correctly, but when I attempt to link them tog...
When dealing with threads (specifically in C++) using mutex locks and semaphores is there a simple rule of thumb to avoid Dead Locks and have nice clean Synchronization? ...
hello .. i'm not sure if what im talking about is an operator overloading question. is it possible to overload keywords in C++?? for example : i need to write loopOver(i=0; ;i++) instead of for(i=0;;i++) ?? is that possible in C++ and i need to have something like 2 addTo 2 instead of 2 + 2 please help thanks in advance ...

Hey guys, Iv'e noticed that when I send a complete packet (collect it's data in a buffer and send) it is much slower than sending the packet byte by byte. Will it be okay if I make an online game using this method? ...
Hi to all, first i would like to say i am Newbie in C++. As part of my master thesis i am writing a program in C++ which also get as parameters the variables m and d (both integers). Were d is the power of 2 (this means 2^d elements). Parameter m define the number of possible interactions between one element and the total group (2^d el...
I am doing some C++ cross development - been doing that for a while on Windows and recently started on Unix. I suppose what I am after is to simplify Unix development experience - I have a local windows box I do development on, and a remote Solaris box which I use to compile and test code on unix environment. What I do now - I develop...
what is the difference between %d and %i when used in printf function ? ...
i'm just reading meyers "More Effective C++ 35 New Ways" - item 33, and he suggest there always to inherit from an abstract base class, and not a concrete. one of the reason he claims, which i can't quite get , is that with inheriting from an abstract class, treating array polymorphically (item 3 in the book) is not a problem. can some...
