[openssl-users] OpenSSL 1.1.0 providing new OIDs to source code

Yes, MY_NID is really NID_whatever. I tried it with putting OPENSSL_init_crypto(0, NULL); at start of my main().
Did not make any difference…
The Integer value of MY_NID will be printed out and is the correct integer value.
And i tried another thing. I replaced the two dll-libraries with the new created ones and then i run my Code and there all will be printed out correctly. BUT the whole time i used some older dll-libraries of openssl, (1.1.0f) and for development i used the latest 1.1.1-dev and then i build this, which has added a new x509 extension (Admission), which has a new OID (NID_extX509Admission, etc.) and there the short and long name will be printed out correctly after Building the Code. So this is a Little bit strange.
Or must i replace the dll-libraries every time i build the Code? But when, why has it worked with the old ones and the 1.1.1-dev (master branch)?

If you've come that far, MY_NID (which I assume is really
NID_whatever) obviously exists, or your code wouldn't even have
compiled. One possibility remains, that for some reason, libcrypto
hasn't been initialised like it should. This can happen if you only
call a very select set of OpenSSL functions. What happens if you add
this at the start of your main()?
(note, that should be seen as a temporary measure, as this is called
internally in quite a number of spots, so for larger uses of OpenSSL
functionality, you shouldn't need that)
