The goal of this project is to create a library for distribution. In the past, I used forward declares so I didn't have to distribute a bunch of header files along with the libraries. However, I'm now trying to eliminate code duplication by switching to templates and am running into some issues. First, a simple example project showi...

Hi I'm new to Xcode. I'm trying to learn c++ and I was wondering if it is possible to have multi projects and choose which project should run. I used ms visual studios before and I like how under a solution I can create multiple projects and choose which one is the executable one. Xcode also has targets not exactly sure what they are may...
Here's the situation: I have three files, Test1.cpp and Test2.cpp. Test1.cpp can be compiled as-is into a stand-alone application. Test1.cpp also contains some functions that I would like to re-use in Test2.cpp. I'm using an #ifndef #endif block to conditionally exclude the main function of Test1.cpp so that when I compile Test2.cpp, ...
Hi, I am able to read the ibus keys configuration to know the keys that trigger an engine ON/OFF (accessible via the property "general/hotkey" and "trigger"). that is all good but that returns lists of strings (gchar*) which combination switches ON/OFF the IME (ex: ["SHIFT+CTRL+F9", "SHIFT+UNDERSCORE",...]). How can I get the correspon...
Hello! The OpenCV library is great. Most functions have the required functionality, however, I would like to modify some of the functions and recompile so that it fits my specific needs. how would we recompile the dlls and other files? is there a built-in script or do we need to write all the scripts ourselves? ...
So, when I pass a const char * to a function once, can I use it again? It appears to end up spitting out crap to me. const char *config_file = "file.txt"; function(int x, config_file); cout << "Number" << x; secondfunction(int y, config_file); Do I need to make another pointer to config_file? If so, how do I do that? Thanks! ...
I tried to compile TinyXML++(or TICPP) using premake4 with these settings: "premake4 vs2010 [--unicode] [--ticpp-shared] [--dynamic-runtime]". It compiles the .libs but I can't compile TiCPP.vcxproj because the compiler says "Unable to start program c:\ticpp\lib\ticpp.lib. This file is an unrecognized or unsupported binary file." Anyone ...
I have a c++ code developed with Visual C++ 2008, which creates a .exe file in the dubug subfolder of the application. The program runs properly on the development machine, a Windows Vista PC, but does not run when installed on another machine, a Windows XP PC on which Visual c++ 2008 is not installed. (I used InstalShield 2010 to deploy...
Hi there, Currently, I am trying to separate the display list from the OnPaint(), but glGenLists(1) return 0. Is there any prerequisite on using display list? Is function glGenLists(1) only survive inside OnXxx() event thread? Thank you! ...
I can't use Boost ASIO (reasons not related to programming) and I looked around and libcurl looks good. I'm building the binaries at the moment and decided to get some feedback from the community. Any comments regarding libcurl/alternatives? UPDATE: libcurl's not great for telnet. It's 2010! Shouldn't there be a simple way to do this?...

I'm still earning my C++ wings; My question is if I have a struct like so: struct Height { int feet; int inches; }; And I then have some lines like so: Height h = {5, 7}; Person p("John Doe", 42, "Blonde", "Blue", h); I like the initialization of structs via curly braces, but I'd prefer the above be on one line, in an anony...
Two Parts two my question. Which is more efficient/faster: int a,b,c,d,e,f; int a1,b1,c1,d1,e1,f1; int SumValue=0; // oops forgot zero // ... define all values SumValue=a*a1+b*b1+c*c1+d*d1+e*e1*f*f1; or Sumvalue+=a*a1+b*b1+c*c1; Sumvalue+=d*d1+e*e1*f*f1; I'm guessing the first one is. My second question is why. I guess a third que...
