Docking - Name clash with opencascade library [message #27429]

I've got a small problem with "struct Handle", private to DockCont, which name is identical to OpenCascade library Handle macro.

The quick solution would be to rename Handle to DockHandle, just few lines of code change and no external visibility, as Handle struct is private.

Mjrt, could you please apply it ? Or, I could commit it by myself if you agree.

Ciao

Hello, Massimo.

It possible to use #pragma push_macro("SomeDefine") to save current defined value to macro stack and #pragma pop_macro("SomeDefine") to load saved value from macro stack.

For example:

#pragma push_macro("Handle")
#undef Handle
#include <Docking/Docking.h>
#pragma pop_macro("Handle")

Tested for GCC and MSC compilers.

Well, that could be a solution... I'll test it.
Anyways, I think it would be better to change the Handle struct name, it doesn't harm.

I know that's an OpenCascade fault, not a Docking one. OpenCascade has thousands of functions/structs/macros and no namespace....

Another solution can be consolidation of used OpenCascade headers to include in separate header file, where you can #undef all clashed macros after using it. Then you can include that header file into application with Docking package.

This is generic suggestions to solve such problems.

Not possible, the Handle() macro is needed everywhere.... It's a sort of smart pointer system made with macro, sigh.
OpenCascade has some very old code parts in it.
It should be rewritten with more modern compilers in mind, but it would be a really huge task.

Anyways, I tested your method and it works too, so it's ok for me.
I was just testing a sketcher app using opencascade.
