Thanks Barto and Téquila for helping us out - I was the one who suggested Al to post his problem here, since I didn't have an overview which x64 resources to point to.
Anyway, while the x86 binaries work on x64 bit Linux, a frequent problem seems to be the
"missing (a 32bit?) libCURL" problem we have observed earlier and which is also the root of Al's post.
This makes me wonder, whether there is anything we can learn from this situation and which we could do to prevent it occurring at a next release. For instance, would it be possible to provide a built-in or packaged version of libcurl?
The HTTP downloading mechanism is more or less used as an update functionality of SG, by Baller Bude and other servers, thus it is becomes a critical part of SG.
My thanks in advance for any helpful thought in this matter.
Best regards,
TheDoctor
