*Bug Reference:* "OpenSSL v1.1.1 could not loaded on Windows platform" https://bugs.freepascal.org/view.php?id=37137 1) I can confirm that the new v1.1.x DLL names are correct. I also checked some of the builds linked from the OpenSSL binary's page. The OpenSSL commit that discusses the name changes: https://github.com/openssl/openssl/commit/520f434b42c83d63d8777075eb66967618551d5b 2) There is a problem with the loading. The DLLs names have to be handled in pairs. If the first DLL fails to load (crypto/util DLL), then both should be skipped and the next pair tried. If the second DLL (SSL lib) fails to load, the first one needs to be unloaded and the pair skipped to try the next pair. Otherwise it is possible to load two DLLs that are not matched versions. Reference master branch code: https://github.com/graemeg/freepascal/blob/master/packages/openssl/src/openssl.pas#L5634
This needs to be checked.
3) I recommend the newest libraries be tried first, working backwards towards the oldest.
This is already so ? The version numbers are added from new to old ?
Both #2 and #3 are demonstrated by this patch on the synapse mailing list: https://sourceforge.net/p/synalist/mailman/message/36933840/ <https://github.com/graemeg/freepascal/blob/master/packages/openssl/src/openssl.pas#L5634> 4) The bug report says "Fixed in Version: 3.2.0", but that appears to be incorrect.
I have changed that to 4.0 Michael. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
