Compiler Flags / Where to find them

In VSCode Changes to default C/C++ Configuration

• Include Path of Python.h Header file "/usr/include/python3.8/**"

python3.8-config --cflags

-I/usr/include/python3.8 -I/usr/include/python3.8  -Wno-unused-result -Wsign-compare -g -fdebug-prefix-map=/build/python3.8-fKk4GY/python3.8-3.8.2=. -specs=/usr/share/dpkg/no-pie-compile.specs -fstack-protector -Wformat -Werror=format-security  -DNDEBUG -g -fwrapv -O3 -Wall 

python3.8-config --cflags

-L/usr/lib/python3.8/config-3.8-x86_64-linux-gnu -L/usr/lib  -lcrypt -lpthread -ldl  -lutil -lm -lm  

If compiling with gcc:

• link standard library to use std -lstdlb

Issues is Module Search Path

If module is not in the system modules, there are not found by default. Either add reequired directory toPYTHONPATHenviroment variable.

or

import os
import sys
sys.path.append(os.getcwd())
