RESOURCES
Python: https://www.python.org/
CPP Extension: https://github.com/godotengine/godot-cpp
SConstruct file:
#!/usr/bin/env python
import os
import sys
env = SConscript("godot-cpp/SConstruct")
For reference:
- CCFLAGS are compilation flags shared between C and C++
- CFLAGS are for C-specific compilation flags
- CXXFLAGS are for C++-specific compilation flags
- CPPFLAGS are for pre-processor flags
- CPPDEFINES are for pre-processor defines
- LINKFLAGS are for linking flags
tweak this if you want to use different folders, or more folders, to store your source code in.
env.Append(CPPPATH=["src/"])
sources = Glob("src/*.cpp")
if env["platform"] == "macos":
library = env.SharedLibrary(
"demoproject/bin/HelloWorld.{}.{}.framework/helloWorld.{}.{}".format(
env["platform"], env["target"], env["platform"], env["target"]

else:

"demoproject/bin/HelloWorld{}{}".format(env["suffix"], env["SHLIBSUFFIX"]),
