Exporting shared library symbols in a crossplatform way?
Is there a cross platform way to selectively export certain functions and structs from a C project which builds a shared library? I want to do in a way that does not require a specific build system (the visibility should be defined in the code, eg as a macro), and in a way which both GCC and MSVC can understand. Thank you. ...
Floating point stack handling with floating-point exceptions turned on

So far so good. However, when I do this, the f...

Why use Visual Studio 6 for C++

Unusual destructor behaviour when copying over stack variables
I wrote a test to check whether destructors were called before an overwriting assignment on a stack variable, and I can't find any rational explanation for the results... This is my test (in Visual C++ 2008 Release mode): #include <iostream> class C { public: char* ptr; C(char p) { ptr = new char[100]; ptr[0] = p;} ~C() { std::cout ...

Converting a Windows Dll to .lib for C++ Visual Studio 2008
I know there is a tool called Dll to lib but the developer is asking $1000. I only need to convert one library, once, so its not easy to justify that price. I tried IMPLIB32.EXE, but I just get empty .lib files. How can I accomplish this? Perhaps I can write a simple conversion app? Added1: The Dll's are typically stdcall not cdecl an...
