Re: [twsocket] ICS V7 bug ?
Here is an article from Microsoft concerning the msvcr71.dll and where to place it. Another case of DLL hell. The only safe way to install an ICS SSL application is to install the two or three SSL and runtime DLLs in the same directory as the program. Otherwise you may get conflicts with other applications also using OpenSSL but using different SSL version DLLs that are either installed in the windows directory or available via a path (as is Subversion). I learnt this the hard way, installing Subversion broke one of my servers. Several FTP clients also use OpenSSL.

Re: [twsocket] ICS V7 bug ?
I always put the libraries in the application folder. For one application, I probably need to switch to another library. I tested RTC yesterday (RealThinClient). It can use commercial SSL libraries like SecureBlackBox of which I have a license of an older version. But after a simple test , I'll discard RTC ICS with SSL was twice as fast as RTC with plain http. It's not so thin either, the compiled exe was 126 kb larger and there's another 200kb for SecureBlackBox , but the complete package would be smaller because I don't need openSsl . Using cab compression, the 2 openSSl libraries are still 613 kB Paul - Original Message - From: Arno Garrels arno.garr...@gmx.de To: ICS support mailing twsocket@elists.org Sent: Sunday, July 26, 2009 10:02 AM Subject: Re: [twsocket] ICS V7 bug ?

I recently managed to build OpenSSL with C++ Builder, so one was able link .obj files rather than the libraries, though I'm not sure whether OpenSSL license allowed this for closed-source applications. That is very interesting. Maybe you could create a wiki page to describe the required steps and provide any required file beside OpenSSl source code. Each person will then decide if the license allows him to do it or not. -- francois.pie...@overbyte.be http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

They contain plenty of dependancies to other run-time libraries. So probably a huge effort to get it working in Delphi. I haven't tried this yet. -- Arno Garrels -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

I had understood that you rebuild OpenSSL DLL using BCB.
