OpenSSL NMAKE Unresolved External Symbol

Question

I'm trying to compile a very light version of OpenSSL with many of the features disabled.

Using the post Build openssl with just RSA and AES I have run the build step successfully, but I have a problem when running nmake.

The first time it ran for a few minutes before failing. Now when I run nmake, it fails in the same way without all the previous text. Output shown below.

D:\xxxxxxxx\openssl-master>nmake

You seem to be using OpenSSL 3.0 which is the as-yet-unreleased still in development version of OpenSSL that you (presumably) downloaded from the git master branch - which is where all active OpenSSL development goes on. As a development branch this should be considered as unstable and not really suitable for any "real" use. It looks like the no-dsa support is currently broken. A fix is here:

https://github.com/openssl/openssl/pull/10375

One way to get things working would be to drop "no-dsa" from your Configure line. Or you could apply the fix at the above URL (or wait a couple of days for it to be merged). Probably though the best route is to just use a stable version of OpenSSL. The latest stable version is 1.1.1d which you can download as a tar from here:

https://www.openssl.org/source/

Alternatively if you have the git repo cloned locally then you can check that version out like this:

$ git checkout OpenSSL_1_1_1d
