typedef struct{ float x, y, z, w; }Vertex4;
class X3DBaseDataObject { public: virtual void destroy(); }; ... ... ...
Where am I wrong? I tried setting the. cpp file to .mm and of type .cpp .objcpp, but still doesn't work. Also
#ifdef __cplusplus extern "C" { #endif
doesn't help.
The likeliest explanation is that the header is being #imported/#included by an Objective-C or C file you don't expect. Find the error in the Issues navigator. There will be a disclosure triangle next to it. One of the rows inside the issue will start with "In file included from." Hover the mouse pointer over that line for about ever, and eventually you will get a tooltip with the full content of that line. It will identify the source file that imported the header.
(You can also go to the Log navigator (last tab) and get a more-conventional build log, in which you still have to click a disclosure triangle, but the path to the file in question is spelled out clearly.)
