How to overcome vc++ warning C4003 while writing common code for both gcc and vc++

Hope this helps I have a code that is compiled in both gcc and vc++. The code has a common macro which is called in two scenarios. , This might work depending on your VC++ version, etc
code :

wish help you to fix your issue This commonly occurs when including a Windows header that defines a min or max macro. If you're using Windows headers, put #define NOMINMAX in your code, or build with the equivalent compiler switch (i.e. use /DNOMINMAX for Visual Studio).
Note that building with NOMINMAX disables use of the macro in your entire program. If you need to use the min or max operations, use std::min() or std::max() from the header.

around this issue I have the following warnings while compiling an openFrameworks 007 project on Visual Studio 2010 SP1: , Add #undef max to the top of the relevant files.

To fix the issue you can do Maybe you placed #define NOMINMAX right before directly including "windows.h" but not before some other header which include it? Try moving it at the same beginning of the source file (if you didn't).

help you fix your problem Since Bitmap locks the underlying stream, you could copy the file contents to a MemoryStream and base the Bitmap on that instead. This should prevent the file from being locked:
code :
var bytes = File.ReadAllBytes(Path);
using (var stream = new MemoryStream(bytes)) // Don't dispose this until you're done with your Bitmap 
{
    Bitmap bt1 = new Bitmap(stream);
    // ...
}

Does that help It is strange to see this warning popping up in Boost. The compiler flag to disable this warning is -Wno-reorder, as per gcc's man page.
In your case, you can use:
