   I am trying to build CPython3.6 from GitHub statically with the Documentation below:

   https://wiki.python.org/moin/BuildStatically

   Changed *shared* to *static*

   And only uncommented the module "testcapimodule" in Modules/Setup file:

   _testcapi _testcapimodule.c # Python C API test module

   And ran with 'make LINKFORSHARED=" "'

   However I got errors that:

       gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes    -std=c99 -Wextra -Wno-unused-result -Wno-unused-parameter -Wno-missing-field-initializers   -I. -I./Include    -DPy_BUILD_CORE  -c ./Modules/_testcapimodule.c -o Modules/_testcapimodule.o
   ./Modules/_testcapimodule.c: In function ‘test_datetime_capi’:
           ./Modules/_testcapimodule.c:2191:9: error: ‘PyDateTimeAPI’ undeclared (first use in this function)
                if (PyDateTimeAPI) {
                    ^
           ./Modules/_testcapimodule.c:2191:9: note: each undeclared identifier is reported only once for each function it appears in
           ./Modules/_testcapimodule.c:2203:5: error: ‘PyDateTime_IMPORT’ undeclared (first use in this function)
                PyDateTime_IMPORT;
                ^
           ./Modules/_testcapimodule.c:2208:1: warning: control reaches end of non-void function [-Wreturn-type]
            }
            ^
           make: *** [Modules/_testcapimodule.o] Error 1

   But when I build Cpython3.6 with *shared*, it can succeed.

   Is this issue only in Python 3.6? I believe Python 3.6 is only receiving security fixes at the moment, so this could only be fixed in 3.7, 3.8 and 3.9.

   It seems like this issue has been fixed in 3.8 and master branches (I didn't test Python 3.7): see below.

   I close the issue. Reopen/comment the issue if you consider that Python 3.7 should be fixed as well.

   I made this change:

   I built Python: it works as expected, _datetime is a built-in module:

   $ ./python
   Python 3.9.0a0 (heads/master-dirty:46b0b81220, Sep 17 2019, 22:42:19) 
   [GCC 9.2.1 20190827 (Red Hat 9.2.1-1)] on linux
   Type "help", "copyright", "credits" or "license" for more information.
   >>> import _datetime
   >>> _datetime
   <module '_datetime' (built-in)>

   Note:

   $ make
   ...
   The following modules found by detect_modules() in setup.py, have been
   built by the Makefile instead, as configured by the Setup files:
   _abc                  _datetime             atexit             
   pwd                   time
