Could not initialize openSSL library ? [SOLVED]
lazarus / 38-Networking and Web Programming

Hi friends.
I have developed a complete Lazarus app and now i want to distribute
it as a demo to my users.
I usually use windows urlmon to download data from the server but, now
i use fphttpclient instead, when i download data from the server.
My hopes is that fphttpclient will work on Mac also.
From Lazarus client, the app works fine but, when i use fphttpclient
in my Lazarus app on a computer without Lasarus i get this error:Could
not initialize openSSL library ?

Is there anyone who can answer which openSSL library, which is
compatible with my Lazarus app, I have to use when I will distribute
the app.

Thanks in advance.
Bob

On Windows, you'll need to include ssleay32.dll and libeay32.dll from
here:

Make sure you have the right bitness (32-bit / 64-bit). They're named
the same.

 On a MAC openssl is phased out? I forgot what replaced it. My Mac is
lazy.

Why are you shouting?

On Mac, they're still there, although deprecated for years:

ceptual/cryptoservices/SecureNetworkCommunicationAPIs/SecureNetworkCom
municationAPIs.html#//apple_ref/doc/uid/TP40011172-CH13-SW3

fphttpclient should work fine on Mac too.

I is not shouting - at least did not mean to -, but current, and it
does not work anymore unless you have a 32 bit mac.

No, works fine. They're universal libs with both 32-bit and 64-bit
architectures.

Note: those DLLs are primarily meant for use with Indy, which
FPHttpClient does not use.  Any OpenSSL distribution should work
fine.  The only real difference between Indy's distribution and other
3rd party distributions is that the DLLs in Indy's distribution have
no external dependencies, such as to Microsoft's VC++ runtime.  Other
distributions may, so be mindful of that.
