Ray- Wow! THANKS for taking the time for such a detailed explanation. That helped tremendously.
I downloaded curl-7.51.0.zip from https://curl.haxx.se/download.html and it all worked beautifully. And I did need mingw32-make.exe mingw32 CFG=sspi-winssl so thanks for your forethought in that. I switched over to libcurl.a, and tried to add the CURL_STATICLIB compiler flag, but the .exe still requires libcurl.dll - is that expected? Compiler flags are: [image: Inline image 2] On Thu, Dec 1, 2016 at 1:37 PM, Ray Satiro via curl-library < firstname.lastname@example.org> wrote: > On 12/1/2016 12:09 PM, Greg Saunders wrote: > > Thanks, Daniel- that got me going in the right direction and I was able to > get it running.
