Short answer: Not likely In order for this to work, you absolutely would have to use a 64-bit processor. Secondly, it would depend on the Operating System support for allocating more than 4G of RAM to a single process. In theory, it would be possible, but you would have to read the documentation for the … Read more
The const is meaningless in that example, and your compiler should give you an error, but if you use it to declare variables of that class between the closing } and the ;, then that defines those instances as const, e.g.: const class A { public: int x, y; } anInstance = {3, 4}; // … Read more
I had exactly the same problem after transferring to macOS High Sierra (though, errors were not the same, but similar). I found a workaround by renaming /usr/local/include to /usr/local/include_old (well, name does not really matter, just the fact that g++/clang will not search for headers in this folder anymore).
You probably have deactivated the debugging information for your project: Right click on your project -> Properties Configuration properties -> Linker -> Debugging Switch “Generate Debug Info” from No to Yes Rebuild your project and retry, it should now run without the message 🙂
First, the signature of your data() function: bool data(struct *sampleData) cannot possibly work, because the argument lacks a name. When you declare a function argument that you intend to actually access, it needs a name. So change it to something like: bool data(struct sampleData *samples) But in C++, you don’t need to use struct at … Read more
From the comments, the problem was caused by using dlls that were built with Visual Studio 2013 in a project compiled with Visual Studio 2012. The reason for this was a third party library named the folders containing the dlls vc11, vc12. One has to be careful with any system that uses the compiler version … Read more
It all starts with glReadPixels, which you will use to transfer the pixels stored in a specific buffer on the GPU to the main memory (RAM). As you will notice in the documentation, there is no argument to choose which buffer. As is usual with OpenGL, the current buffer to read from is a state, … Read more
Windows manifest files are Win32 resources. In other words, they’re embedded towards the end of the EXE or DLL. You can use LoadLibraryEx, FindResource, LoadResource and LockResource to load the embedded resource. Here’s a simple example that extracts its own manifest… BOOL CALLBACK EnumResourceNameCallback(HMODULE hModule, LPCTSTR lpType, LPWSTR lpName, LONG_PTR lParam) { HRSRC hResInfo = … Read more
How about this :- std::ifstream inFile(“file”); std::count(std::istreambuf_iterator<char>(inFile), std::istreambuf_iterator<char>(), ‘\n’);
Aside from the fact that there’s no call (and therefore no associated expenses, like parameter preparation before the call and cleanup after the call), there’s another significant advantage of inlining. When the function body is inlined, it’s body can be re-interpreted in the specific context of the caller. This might immediately allow the compiler to … Read more
