I figured out part of the problem. I had the library in my gcc command for
python as -L (path)\Python310\libs. It should just be -L (path)\Python310.

Subject: Errors creating executable for python script using cython and gcc
I'm having issues trying to get cython working with the gcc compiler. I want
to use the gcc compiler because I've heard it's harder to get your code from
the executable than using pyinstaller.
I'm on 64-bit Windows 10 and my target, for now, is the same.
I have an application that is written in python 3.10.4. It is a command line
application that goes against AWS, so there are no Windows calls in it.
I can produce the executable using pyinstaller and it runs just fine.
my code starts like this:
import src.python.app_name
import sys
def main(argv):
src.python.app_name.main(sys.argv[0:])
if name == "main":
main(sys.argv[0:])
However, when I use the cython command to produce the .c module with a
command like this:
cython -3 -o app.c app.py src\python\app_name.py
That seems to work just fine or at least it doesn't generate errors.
Then I tried to create the executable and I've run into all sorts of
problems that many others have run into on the internet, too.
I compile it with this command:
gcc -Wall -m64 -I (path)\Python310\include -L (path)\Python310\libs
-lpython310 name.c -o name.exe
and I get this:
name.c:220:41: warning: division by zero [-Wdiv-by-zero]
220 | enum { __pyx_check_sizeof_voidp = 1 / (int)(SIZEOF_VOID_P ==
sizeof(void*)) };
| ^
name.c:220:12: error: enumerator value for '__pyx_check_sizeof_voidp' is not
an integer constant
220 | enum { __pyx_check_sizeof_voidp = 1 / (int)(SIZEOF_VOID_P ==
sizeof(void*)) };
| ^~~~~~~~~~~~~~~~~~~~~~~~
I've tried adding the -DMS_WIN64 option to the gcc command, but then it
sends a bunch of undefined reference errors regarding __imp_Py* and it
complains about undefined reference to `WinMain'
I have no clue how to fix this. Can someone help me?
I'm using gcc version 12.1.0
I have a main routine defined like I mentioned. Not a WinMain routine.
