Make File Compiler Flag explanation

[PARTHIBAN_K]

Can anyone explain this compiler flag in Creo Toolkit Make File

MACH = -DPRO_MACHINE=36 -DPRO_OS=4
CCFLAGS = -c -GS -fp:precise -D_WSTDIO_DEFINED
CFLAGS = $(CCFLAGS) $(INCS) $(MACH)

 Why we defining DPRO_MACHINE = 36 & DPRO_OS=4 ?

Per my knowledge

DPRO_MACHINE = 36 is for X86E_WIN64

DPRO_OS = 4 is for WINDOWS

And those are used to set PreprocessorDefinitions.

FYI: 

LINUX : 34
IA64_NT : 35
X86E_WIN64 : 36
X86E_LINUX64 : 37
APPLE_OSX : 38

/* Operating systems */
VMS_OS : 1
UNIX_OS : 3
WINDOWS_32 : 4

Hope that helps 🙂

@PARTHIBAN_K Sorry I do not have any web link or seperate material for that.

It's something I came across/understood when I started working with Toolkit.
