Summary0000656: WildMagic4 doesn't build on 64-bit Mac OS
Descriptionsrc/Mod/Mesh/App/WildMagic4/Wm4System.cpp relies on Carbon API calls. Since Carbon is 32-bit this is blocking my 64-bit build. It builds if you take out the offending code block, but not clear what effect this will have.

It seems that only these functions are used:
* Wm4::System::Memcpy
* Wm4::System::Read4le
* Wm4::System::Write4le
* Wm4::System::Fclose
* Wm4::System::Read8le
* Wm4::System::Fopen
* Wm4::System::Write8le

Can you send a patch of your modifications, please?

I'm reluctant to suggest anything since at the moment I don't have a working Mac build. I got a cmake setup to compile but the program immediately crashes with some kind of segfault. Haven't had time to look into it further.

But if you're sure System::GetPath is not used, then I suppose this crude workaround should be okay. Too bad the linker is trying to put this in if it's not needed; sounds like we could cut some things from the WildMagic includes in general?

Basically I just did:
571c571
< #ifdef __APPLE__
---
> #if defined(__APPLE__) & !defined(__x86_64__)

Which got me through with gcc. Obviously not ideal; will update next time I try to build; I'm on a MacBook so it's a slow process.

Cool, hope this works for people. A remaining issue is that I think checking for __x86_64__ is gcc specific. There must be better ways to check whether the build is 64-bit but I haven't tested them.

On Mac the mostly used compiler is still gcc to build FreeCAD. If somebody uses the Clang compiler, Intel, Borland or something else then the FreeCAD sources need to be ported anyway. So, for now this issue is solved.
