Carl,

I'm guessing, but you are running on Windows? If not ignore this note.

I don't know enough to give you an absolute answer, but I have had a
previous experience that may help you figure out what you need to do.

I have (build and use) Apache and OpenSSL.

When I got curl for the first time, to play around with it, I got both
the SSL version as well as the non-SSL version. I could get the non-SSL
version to work ok but the SSL version would't do anything ... no errors
... nothing. I gave up and left it for a while.

Then (somehow) I did something that generated an error ... I cannot
remember how I did it and I can't reproduce it. But the jest of this
is, it was looking for (trying to load DLL's with different names). I
renamed my SSL DLL's (I think) to these names and it worked. Later on I
built the code (cURL/libcurl) myself and no longer have trouble, but I
am still not totally certain of the issue.

What I think happened is that OpenSSL changed the names of their DLL's
... your Apache/PHP is using the new named ones and cURL wants the older
ones. I think the SSL libs from the cURL site are old.

This doesn't totally make sense - but I havn't taken the time to figure
it out -- I have built the code myself and don't have the problem any
more. But I also can't confirm what I built works with SSL either ... I
never got around to checking.

I have to look again to see if I had to change anything with the recent
builds ... I don't think so, but I will try building cURL again and see.

In the mean time, I have a tool you can run to look at what DLL's are
needed and perhaps this will help you figure out what to do. It will
list the DLL's a program needs and will say if it can or cannot load
them.

A friend at work wrote the tool, there are no restrictions on its use,
copying or otherwise and obviously there is no support or guarantee -
it won't hurt anything though.

[c:\]jschkdll.exe curl.exe

If I discover more information I will send you a note...
Let me know how you make out.

Chris.
