How to build Python 3.7 on Fedora 36 for use with go-python/cpy3?

dnf -y install gcc openssl-devel bzip2-devel libffi-devel zlib-devel xz-devel wget pkg-config
# optional:
# dnf -y groupinstall development-tools
cd /usr/src/
wget https://www.python.org/ftp/python/3.7.13/Python-3.7.13.tgz
tar xzf Python-3.7.13.tgz
cd Python-3.7.13/
./configure --prefix=/opt/python37 --enable-shared
make -j `nproc`
make install
echo 'export PATH=$PATH:/opt/python37/bin' > /etc/profile.d/python37path.sh
export PATH=$PATH:/opt/python37/bin
echo /opt/python37/lib > /etc/ld.so.conf.d/python37.conf
ldconfig
echo 'export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/opt/python37/lib/pkgconfig' > /etc/profile.d/python37pkgconfig.sh
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/opt/python37/lib/pkgconfig

# verify with
# python3.7 --version
# pkg-config --list-all

Hi!
Since the newest APIs has changed a bit, here is a code example that works for now.
Now, you need to use python3-embed instead of python3 in #cgo directive.

Here is the code that works for me.

package main

// #cgo pkg-config: python3-embed
// #include <Python.h>
import "C"

import (
	"unsafe"
)

func main() {
	pycodeGo := `
import sys
for path in sys.path:
  print(path)
`

	defer C.Py_Finalize()
	C.Py_Initialize()
	pycodeC := C.CString(pycodeGo)
	defer C.free(unsafe.Pointer(pycodeC))
	C.PyRun_SimpleString(pycodeC)
}

Fedora release 37 (Thirty Seven)
Python 3.11.1
gcc (GCC) 12.2.1 20221121 (Red Hat 12.2.1-4)

Thank you for tips above @christian-korneck
