for example in "MDrawContext.h":
#if defined(__linux__) && __GNUC__ >= 8
friend class MDrawContext;
#endif
This will cause compilation error in linux under gcc < 9, like this:
‘Autodesk::Maya::OpenMaya20220000::MHWRender::MPassContext::~MPassContext()’ is private within this context
class OPENMAYARENDER_EXPORT MDrawContext : public MFrameContext
^~~~~~~~~~~~
I wander why this predefined line shows up in high versions of maya, and how could i compile this under linux gcc 8.5.
Now my solution is to directly modify these header files changing 9 to 8
