Delay loaded shared objects
Hi All, I am not sure whether this is the right list. Please let me know if there is a more appropriate list for this question. Does gcc/g++ (on a typical Linux platform) supports delayed loaded shared objects similar to the /DELAYLOAD option of MSVC [1]? The Win32 delay load implementation hides the LoadLibrary and GetProcAddress logic from the programmer (those are similar calls to dlopen/dlsym on Unix). Dependent DLLs are only loaded into library until the first function in this library is called. Many thanks, Robert [1] http://msdn.microsoft.com/en-us/library/151kt790.aspx
