Hi Ray, thanks for getting back to me. Please excuse my ignorance/inexperience but i'm very new to C++ (and OOP, compiling/linking in general). I'll try and explain as best i can what I have done so far and hopefully you will be able to advise how to proceed.
I am developing an application that uses the cURL library to post JSON format data. The requirement at my installation is to use the Watcom compiler which intially caused a few headaches, but I have managed to overcome them with some help from Luca on this mailing list. I downloaded cURL 7.64.0 and have been using the curl header in my application to carry out the post operations. In order to get around the problem of the Watcom calling conventions being different to CDECL, under the guidence of Luca I generated an import Lib for Watcom from the libcurl.dll and have been using that when compiling and linking to generate my executable. My application works fine under Windows 7 and 10, however, I get the bcrypt.dll missing error message when attempting to run it on Windows XP. If you require any further information, please let me know and I will do my best to assist you. Kind regards, Dan. ________________________________ From: curl-library <curl-library-boun...@cool.haxx.se> on behalf of Ray Satiro via curl-library <curl-library@cool.haxx.se> Sent: 02 July 2019 08:24 To: curl-library@cool.haxx.se Cc: Ray Satiro Subject: Re: Missing bcrytp.dll when running Watcom compiled Libcurl program on XP.

I am aware that XP is no longer supported, however, at my installation we still have a couple of legacy machines that we require to still run XP. I have openSSL 1.1.1c installed on Win 7 machine, and have copied the libcurl.dll, lincrypto-1_1.dll and libssl-1_1.dll files to one of legacy XP machines, however, when trying to execute the program, it says that "brcypt.dll" is missing. I undertand that bcypt.dll was introduced in in Windows operating systems later than XP, so it works fine on our Windows, 7 and 10 machines. I would be extremely grateful if anyone could suggest a method that would enable my program to run on Windows XP. How exactly did you build curl? I see in Makefile.Watcom WINVER is set to Vista when IPv6 is enabled at build time [1]. We may have similar logic elsewhere. In other words some features may require targeting later versions of Windows for some compilers. The official build of curl for windows [2] works on XP and comes with IPv6 enabled. To use that libcurl.dll you would also need the OpenSSL DLLs and there is a link to them on the same page.
