Re: MSVC Compiling OpenSSL on Windows 64 issues with missing libs

[Raymi Coevan <raymi.coevan@xxxxxxxxx>]

Hi,

Indeed, the list you mentioned is exactly the one I have in my environment. In my MSVC project, I only statically link with libcrypto64MT.lib and libssl64MT.lib. No reference is made to libeaymt64.lib or libssl64MT.lib, from what I know at least. So I don't understand why I got these link errors...

Yes, the libraries have changed name for 1.1.0, with names that are
more in line with the Linux / MacOS X names.

I tried that one with standard installation location
(c:/OpenSSL-Win64), and here's what I found (looking for *.lib) that's
relevant:

    c:/OpenSSL-Win64/lib/VC/libcrypto64MDd.lib
    c:/OpenSSL-Win64/lib/VC/libssl64MDd.lib
    c:/OpenSSL-Win64/lib/VC/libcrypto64MD.lib
    c:/OpenSSL-Win64/lib/VC/libssl64MD.lib
    c:/OpenSSL-Win64/lib/VC/libcrypto64MTd.lib
    c:/OpenSSL-Win64/lib/VC/libcrypto64MT.lib
    c:/OpenSSL-Win64/lib/VC/libssl64MTd.lib
    c:/OpenSSL-Win64/lib/VC/libssl64MT.lib
    c:/OpenSSL-Win64/lib/VC/static/libcrypto64MDd.lib
    c:/OpenSSL-Win64/lib/VC/static/libssl64MDd.lib
    c:/OpenSSL-Win64/lib/VC/static/libcrypto64MD.lib
    c:/OpenSSL-Win64/lib/VC/static/libssl64MD.lib
    c:/OpenSSL-Win64/lib/VC/static/libcrypto64MTd.lib
    c:/OpenSSL-Win64/lib/VC/static/libcrypto64MT.lib
    c:/OpenSSL-Win64/lib/VC/static/libssl64MTd.lib
    c:/OpenSSL-Win64/lib/VC/static/libssl64MT.lib

>From those, I guess you need to change your dependencies to be
libcrypto64MT.lib instead of libeaymt64.lib, and libssl64MT.lib
instead of ssleaymt64.lib.

Cheers,
Richard
