Python plugin

[Kafra Pavianne]

Hi!!

i'm trying to add python 3.9 source to my plugins. test.c

#include <Python.h>

int main()

{

    PyObject* pInt;

    Py_Initialize();

    PyRun_SimpleString("print('Hello World from Embedded Python!!!')");

    Py_Finalize();

    printf("\nPress any key to exit...\n");

    if(!_getch()) _getch();

    return 0;

}

But when i compile i have an error including python

        CC      test.c
test.c:3:10: fatal error: Python.h: No such file or directory
    3 | #include <Python.h>
      |          ^~~~~~~~~~
compilation terminated.
make[1]: *** [Makefile:106: ../../plugins/test.so] Error 1

i research a little about it on stackoverflow and im seeying to pass the flags into plugins makefile like this

Makefile: Makefile.in
    @$(MAKE) -C ../.. src/plugins/Makefile

.SECONDEXPANSION:

../../plugins/%@DLLEXT@: %.c $(ALL_H) $$(shell ls %/* 2>/dev/null)
    @echo "    CC    $<"
    @$(CC) $(COMMON_INCLUDE) $(THIRDPARTY_INCLUDE) @PLUGINSTATIC@ @DEFS@ @CFLAGS@ -I/usr/include/python3.9  -Wno-unused-result -Wsign-compare -g -ffile-prefix-map=/build/python3.9-FZ7wim/python3.9-3.9.5=. -flto=auto -ffat-lto-objects -specs=/usr/share/dpkg/no-pie-compile.specs -fstack-protector -Wformat -Werror=format-security  -DNDEBUG -g -fwrapv -O3 -Wall @CPPFLAGS@ @LDFLAGS@ -L/usr/lib/python3.9/config-3.9-x86_64-linux-gnu -L/usr/lib/x86_64-linux-gnu  -lcrypt -lpthread -ldl  -lutil -lm -lm @SOFLAGS@ @LIBS@ @MYSQL_LIBS@ -o $@ $<

And when i compile with flags i got this error, like the python 3.9 is included now, but the linker doesnt work.

Could anyone help me how to solve this and add python to my plugins?

Thank you so much

undefined referenced like

undefined reference to `Py_Initialize'

show what you not linking with python library. need something like

-llibpython

but probably with full path to libpython.so with version number in name

you can see what library to use in other programs what linked to python.

Was the ldflags failling while linking python.

Now i can use python on my plugins and its libs.

Thank you!
