The whole 32 bit vs 64 bit thing is a pain. On Windows and Linux you have to load all kinds of unobvious things. On AIX it just works. Code from 1988 (when I lost source code for half a dozen programs) still works on current machines. Why the others make it SO HARD is beyond me. In AIX old code works. One flag – saying you want 64 bit – is all you need to add to the Makefile. Otherwise is just works as always. It took me MONTHS to figure out how to make Linuc work – had to yum 32 bit, 64 bit, a compat set, etc. Nightmare.

Wish people would consider keeping things compatible like IBM does. Ditto on new features. Any new feature you merely need to add a flag, and all is good. Otherwise the old ones keep working. An example is POSIX. With IBM/AIX you could do things the old way, or set a flag for POSIX.

Yes, we have had the same source (with updates, I did do the POSIX updates) since 1988. Never a problem. Partly, I think, because they don’t deprecate ANYTHING. Use the old routines if you like. Or not if you chose.

Your problem is not having ALL of the required libraries! That is it. Finding what you need is the challenge.

I tried to build stunnel from the sources.

The compiling goes well ,but the linking gives an error

When comping 32bit I get :

sthreads.obj : error LNK2019: unresolved external symbol _CRYPTO_set_id_callback referenced in function _sthreads_init

..\bin\win32\stunnel.exe : fatal error LNK1120: 1 unresolved externals

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.16.27023\bin\HostX86\x86\link.EXE"' : return code '0x460'

Stop.

Anyone knows how to solve.
